Definitions
- the present invention relates to disposable hygiene products and more specifically, to methods and apparatuses for processing disposable hygiene products. More specifically, the invention relates to cutting and applying segments of one web to attach to a disposable diaper.
- diapers comprise an absorbent insert or patch and a chassis, which, when the diaper is worn, supports the insert proximate a wearer's body. Additionally, diapers may include other various patches, such as tape tab patches, reusable fasteners and the like.
- the raw materials used in forming a representative insert are typically cellulose pulp, tissue paper, poly, nonwoven web, acquisition, and elastic, although application specific materials are sometimes utilized. Usually, most of the insert raw materials are provided in roll form and unwound and applied in assembly line fashion. As in many manufacturing operations, waste minimization is a goal in web processing applications, as products having spliced raw materials cannot be sold to consumers. Indeed, due to the rate at which web processing machines run, even minimal waste can cause inefficiencies of scale.
- a slip-and-cut applicator is typically comprised of a cylindrical rotating vacuum anvil, a rotating knife roll, and a transfer device.
- an incoming web is fed at a relatively low speed along the vacuum face of the rotating anvil, which is moving at a relatively higher surface speed and upon which the incoming web is allowed to “slip”.
- a knife-edge mounted on the rotating knife roll, cuts off a segment of the incoming web against the anvil face.
- This knife-edge is preferably moving at a surface velocity similar to that of the anvil's surface. Once cut, the web segment is held by vacuum drawn through holes on the anvil's face as it is carried at the anvil's speed downstream to the transfer point where the web segment is transferred to the traveling web.
- the present invention allows for square, and non-square, and preferably trapezoidal, ear webs to be applied to a traveling web, with zero or minimized waste present in the incoming ear web. Zero material is wasted due to the geometry of the chosen ear pattern and its downstream processing.
- An ear is a component of a diaper that is grasped and pulled around the waist of a wearer.
- ears are secured to the diaper at a first end, and a second free end is typically equipped with securing means, such as a pressure sensitive adhesive, or hook and loop material.
- securing means such as a pressure sensitive adhesive, or hook and loop material.
- elasticity provided about the waist region of the diaper allows the free end to be snugly pulled about the waist of a wearer.
- Ears can be rectangular or made of irregular shapes.
- the present invention provides a process wherein a rotary knife or die, with one or more cutting edges, turns against and in coordination with a corresponding cylinder to create preferably trapezoidal ears.
- Ear material is slit into two lanes, one for a left side of a diaper and the other for a right side of a diaper. Fastening tapes are applied to both the right and the left ear webs. The ear material is then die cut with a nested pattern on a synchronized vacuum anvil.
- the resulting discrete ear pieces however, due to the trapezoidal pattern of the ears, alternate between a correct orientation and an incorrect (reversed) orientation.
- the reversed ear is required to be rotated 180° into the correct orientation such that the ears and associated tape present a left ear and a right ear on the diaper.
- Two ear turner assemblies can be provided, to rotate every other ear applied to the right side of the product, and every other ear applied to the left side of the product. In this manner, for a single product, one of the two ears will have been rotated 180°.
- Ear application to a chassis web can be by a bump method (described later) with intermittent adhesive applied to the chassis web or can be by vacuum transfer.
- the present invention also allows for two side panel assemblies, including fastening mechanisms, to be attached to two ears, the side panel assemblies attached in a pre-folded condition. Two more ears can be coupled to a chassis web to create a front panel to wear about the waist of a user.
- the present invention also allows for chips of material to be removed from the ears to provide a diaper with contoured leg openings.
- the chips may be removed from the ears before the ears are attached to the chassis web.
- the chips may be removed from the ears after the ears are attached to the chassis web.
- the chips may be removed from the ears and a portion of the chassis web removed after the ears are attached to the chassis web.

- FIG. 1 a diagrammatic illustration of a prior art process for applying tabs to webs in a diaper making process, to result in an intermediate product shown in FIG. 2 .
- the present invention can use this prior art method of affixing the segments 12 to the web 10 , with a different anvil, the new anvil 114 described below.
- Web 10 is a composite material used in formation of diapers which is generally formed of various layers of material such as plastic back sheets, absorbent pads and nonwoven top sheets.
- a series of ears 12 are applied to web 10 .
- a rotatable vacuum anvil 14 is used to supply the ears 12 to web 10 .
- Anvil 14 has internally reduced air pressure or vacuum (not shown), and a plurality of openings 24 are provided through its surface to enable suction of the tab segments 12 against the anvil surface 14 .
- a web of the ear tab forming material 16 is fed by rollers 20 and 22 against the anvil surface 14 where it is cut into segments by a rotary knife 18 .
- the surface of the anvil roll 14 can have vacuum holes 24 on its smooth surface.
- the infeed of the ear tab forming material 16 can be at a first speed (with individual ears 12 spaced together), after which the individual ears gain speed to the speed of the anvil 14 .
- Typical infeed speeds could be 120 mm/product for the infeed, while anvil speeds could be 450 mm/product on the anvil.
- This transition from the slower first speed to the quicker second speed takes place at the cut point, the ear tab forming material 16 slipping on the anvil 14 until cut.
- it is desired to place vacuum on the ears because centrifugal force would try to throw the ears off of the vacuum anvil 14 .
- Ear webs 16 can be comprised of two portions, 12 a and 12 b , as shown in FIG. 2 .
- Segment 12 a is more specifically referred to as the tab section of the ear 12
- segment 12 b is the ribbon section of the ear 12 .
- the ears can comprise a trapezoidal shape, as shown in FIGS. 6, 7A and 7B , which will be described later.
- the trapezoidal shape of FIGS. 7A and 7B is particularly advantageous for zero waste applications, where it is desired to reduce or eliminate the scrapping of raw material.
- two parallel series of alternating ear webs 16 with ribbon sections of the ear 12 could be created by mirroring the web 16 as shown in FIG. 3 and placing the mirrored web down one/half of an ear length (not shown).
- FIG. 4 a front view of an anvil roll 114 is shown carrying ear forming material 16 (and later, individual ears 12 ) in phantom.
- the anvil roll 114 is preferably formed with two vacuum portions 116 separated by a center groove portion 118 .
- the vacuum portions 116 are preferably mirror images of each other.
- the anvil roll 114 is symmetrical about a center plane through its circumference.
- Each vacuum portion 116 contains several circumferential rows of circular vacuum holes 24 .
- Each vacuum portion 116 may also contain a circumferential groove 120 with an additional circumferential row of vacuum holes 24 located in the circumferential groove 120 .
- each anvil pocket 122 is a groove which extends across the face of the entire anvil roll 114 .
- One ear retaining portion 124 is located on each of the vacuum portions 116 .
- Each ear retaining portion 124 has an ear vacuum hole pattern 126 made of a plurality of vacuum holes 24 located at or near the surface of the anvil roll 144 .
- a plurality of rows of vacuum holes 24 can be employed, each row having a plurality of vacuum holes 24 , although more or less than those configurations or patterns shown can be used.
- FIG. 5 a schematic view of a nested zero waste ear applicator device and methods of the present invention are shown.
- Components of this ear applicator include a web slitter 210 , which processes incoming ear web material 16 into two parallel paths (not shown from this view). After being slit, ear web material is processed by tape applicator 220 , which can add tape to the ears for securing the ears 12 about the waist of a wearer.
- an ear die is used to cut the ear web 16 into the pattern shown in FIG. 7A .
- the ear material 16 is die cut with a nested pattern on a synchronized vacuum anvil/die combination 230 / 232 and carried by rotation or otherwise to an ear turner assembly 200 .
- ears 12 having different heights, H 1 and H 2 can be produced in this configuration by speeding up or slowing down the infeed rate of material 16 into the anvil/die combination 230 / 232 . In this manner, more or less slip is allowed on material 16 prior to cutting, resulting in longer or shorter ears.
- the ear material 16 has already been slit into two lanes, one for a left side of a diaper and the other for a right side of a diaper, it is noted that two parallel ear dies 230 are used to produce the pattern shown in FIG. 7A to the slit web 16 , but because of the side vantage point of FIG. 5 a only one of the lanes is visible if more than one is desired.
- the resulting discrete ear pieces however, due to the trapezoidal pattern of the ears shown in FIG. 7A , alternate between a correct orientation A and an incorrect (reversed) orientation B.
- the reversed ears B are required to be rotated 180° into the correct orientation A such that the ears and associated tape present a left ear and a right ear on the diaper, such as that shown on FIG. 7B .
- correct orientation A such as shown in FIG. 7B
- the shorter of the parallel edges of the trapezoid will face toward an outside, left for the left side, and right for the right side. This geometry is desirable to accommodate the legs of the wearer when the ears 12 are pulled about the waist of the wearer.
- an ear turner assembly 200 that has a series of pucks 234 that travel radially from a minimal radius R 1 (and therefore a minimal tangential speed) to a maximal radius R 2 (and therefore a maximal tangential speed) at a depositional site.
- R 1 and R 2 The difference between R 1 and R 2 is such that individual pucks 235 can be unnested and allow clearance (in the radial direction from adjacent pucks 234 ) for every other ear to be rotated, as will be described later in relation to FIGS. 10 a and 10 b .
- the rotated ears are then unnested and into the correct orientation and brought to the proper speed for deposition onto either an additional vacuum drum (as shown on FIG. 5 a ) and subsequently onto web 10 or high vacuum drum 250 .
- FIG. 7A two lanes of ears 12 are depicted, 16 A and 16 B representing right and left ears intended for a product.
- the longest side of the ears 12 is intended for attachment to web 10 , so because trapezoids are desirable, every other trapezoid in each lane will require 180° rotation to allow the desired side (for example, the longest side) of the ear 12 to be confronted with attachment to web 10 .
- All of the “B” labeled ears 12 on supply 16 A will be rotated 180° into an A position.
- All of the “B” labeled ears 12 on supply 16 B will be rotated 180° into an A orientation position to achieve the desired depositional orientation shown in FIG. 7B .
- ear configurations can vary as shown in FIGS. 7C-7F .
- FIGS. 7C and 7D wavy or curved ear patterns are shown.
- FIG. 7E a square pattern is shown.
- FIG. 7F a trapezoidal pattern is shown.
- Chips may be cut out in any shape of ear patterns, such as such in FIG. 7F .
- the chips can be of any shape or size and can be positioned either on edges of the ears or on the interior of the ears.
- Vacuum drum 240 is a size change roll that matches pitch. Vacuum drum 240 can also be used as a roller, in conjunction with or replacing roller 260 , FIG. 16 .
- the rotation of high vacuum drum 250 is quicker than that of vacuum drum 240 .
- the higher vacuum in drum 250 relative to drum 240 allows the ears 12 to be snatched or grabbed at the higher rotational speed present in drum 250 .
- FIG. 5 a a schematic view of a nested zero waste back ear applicator device and methods of the present invention is shown, with an alternate web path configuration.
- FIG. 8 a perspective schematic view of the nested zero waste back ear applicator device and methods of the present invention is shown.
- two ear turner assemblies 200 R (right) and 200 L (left) are provided, to rotate every other ear 12 applied to the right side of the chassis web 10 , and every other ear 12 applied to the left side of the chassis web 10 .
- one of the two ears will have been rotated 180°.
- two types of pucks are provided, non-rotating pucks 234 A and rotating pucks 234 B.
- the non-rotating pucks 234 A carry the “A” ears shown in FIG. 7A , or the ones that do not require rotation.
- the rotating pucks 234 B carry the “B” ears shown in FIG. 7A .
- ears 12 are picked up from the ear die/anvil station 230 / 232 and rotate about the rotator 200 , while every rotating puck 234 B also rotates radially during rotation of the rotator 200 , as will be described later.
- the ears 12 are then deposited onto chassis web 10 and bonded thereto, for instance by ultrasonic bonding ring 252 , where the resulting product is sent downstream for further processing.
- FIG. 8 a a perspective schematic view of the nested zero waste back ear applicator device and methods of the present invention with an alternate web path configuration is shown.
- This is the preferred embodiment of the vacuum drum/ultrasonic bonding ring 250 / 252 in relation to the vacuum drum 240 .
- the ears are ultrasonically bonded to the chassis web 10 between the vacuum drum/ultrasonic bonding ring 250 / 252 and the vacuum drum 240 as the chassis web 10 travels from right to left as pictured.
- FIG. 9 a side view of the ear turner assembly device 200 is shown.
- the ear turner assembly device 200 used to rotate alternating ears, again with the entire device 200 , rotating about a central axis, and each puck 234 traveling radially from a minimal radius R 1 to a maximal radius R 2 at a depositional site during rotation, and then back to the minimal radius R 1 .
- the difference between R 1 and R 2 is such that individual pucks 235 can be unnested and allow clearance for every other ear to be rotated. Comparing the During rotation from the R 1 to the R 2 position, rotating pucks 234 B undergo not only the increase in radius, but also undergo 180° rotation about an axis perpendicular to the central axis.
- FIG. 10 a a front view of the ear turner assembly device 200 used to rotate alternating ears is shown.
- the pucks 234 are each equipped with vacuum voids 236 through which a vacuum is pulled, retaining ears on the rotator device 200 through their rotation (radially rotating for every ear, radially and axially rotating for every other ear) until deposition.
- the pucks 234 are can be roughly trapezoidal in shape to roughly match the shape of the ears 12 .
- the non-rotating pucks 234 A remain in their axial non-rotated position relative to the rotating pucks 234 B, which rotate from their initial position nested between two non-rotating pucks 234 A, and back.
- the pucks 234 are configured to receive wavy shaped ears as described earlier.
- the pucks 234 are configured to receive trapezoidal shaped ears as described earlier. It is preferable to configure the pucks 234 to match the desired ear pattern.
- FIG. 11 a perspective view of the two ear turner assembly devices 200 R and 200 L are shown. Also shown are vacuum manifolds used to apply the vacuum to the pucks 234 . In this sense, the rotation of the pucks 234 is described in currently pending U.S. application Ser. No. 11/244,387, which is incorporated herein by reference. A front view of this configuration is shown in FIG. 13 and a side view in FIG. 14 .
- FIG. 12 a mechanism for rotating pucks 234 b is shown.
- screws 236 are provided such that movement of the pucks 234 B away from the center axis simultaneously causes rotation of puck 234 B.
- a radially traveling coupling 238 couples the puck with the screw 236 , and when the threads of the screw are engaged with the radially traveling coupling 238 , rotation is caused.
- FIG. 15 is a cross-sectional view of the ear turner assembly device 200 used to rotate alternating ears along the line shown in FIG. 12 .
- screws 236 are operably coupled with pucks or rotator assemblies 234 .
- pucks 234 are moved along a radial line in relation to shaft turner 246 .
- Vacuum manifold 244 is provided to commute vacuum to the pucks 234 and ultimately to hold the ears 12 in place.
- Ear turner cam 242 is provided for rotative purposes.
- FIG. 16 a front view of a rotatable vacuum wheel 114 , ultrasonic bonding ring 252 , and vacuum pattern 124 used for pitch changing ears from a slower web and applying and bonding the ears 12 sandwiched between roller 260 and the anvil 114 to a faster moving chassis web is shown.
- the aggressive vacuum pattern 124 on high vacuum drum 250 will have withdrawn ears 12 from vacuum drum 240 .
- This step follows the rotation of the “B” ears as described above.
- the chassis web 10 is fed in between the roller 260 and the high vacuum drum 250 .
- the ultrasonic bonding ring 252 couples the ears 12 with the chassis web 10 (refer to FIG. 5 ).
- FIG. 17 a schematic view of the nested zero waste back ear applicator device 200 an alternate embodiment of a means for applying the ear 12 to the chassis web 10 is shown.
- a protuberance carrying rotatable body 274 is urged against the chassis web 10 , as disclosed in U.S. Pat. No. 6,475,325, which is incorporated herein as if fully set forth.
- the disclosure of U.S. Pat. No. 6,475,325 is referred to as the “bump transfer” method.
- intermittent adhesive is applied to the chassis web 10 at station 270 .
- the intermittent adhesive is applied at intervals to make contact with ears 12 carried by rotating body 200 .
- the protuberance carried by body 274 urges the chassis web 10 towards an ear 12 carried by a puck 234 .
- the coupled material is processed by final bonding station 272 , after which the ear/chassis combination is sent downstream for further processing as desired.
- FIGS. 18-28 schematic and plan views are presented of a novel disposable garment configuration using methods of performing nested zero waste back ear application including a multi-component ear portion fabrication, bonding and folding.
- the embodiments of FIGS. 18-28 are particularly well suited for formation of what is called in the industry as an adult-sized diaper.
- the products are required to be quite large (for instance, 32′′ wide in a non-stretched condition) in the waist section to fit about the waist of an adult.
- the adult-sized products are typically shipped in packages about 8′′ wide, so the products require folding, particularly at the waist zone where the product is the widest, in order to be compactly packaged and shipped.
- the prior art often employed a Z-fold of ears to get the waist band down to size.
- the ears 12 applied to web 10 shown in FIG. 2 would have to be folded as to not extend much past the profile of the chassis web 10 . This assists both processing of the web as it avoids flying parts, but also assists packaging and transport of the material.
- FIGS. 18-28 show construction of an ear segment that can be formed of multiple pieces, as opposed to the one-piece ears of the prior art (see, e.g., ears 12 of FIG. 2 ). This allows both creation of a contoured multi-piece ear segment, as well as assembly of at least portions of the ear segment in a pre-folded condition.
- a plan view of an ear tab forming material 316 is shown entering the system similarly positioned to material 16 shown on FIG. 8 or 8 a .
- the ear tab forming material (or wing) 316 is a non-woven continuous web of material which is ultimately formed into shaped ear portions 312 .
- Shaped ear portions 312 as described with respect to FIGS. 7 a -7 f , can take on different shapes, and can have correct original orientation, or orientation that requires re-phasing or turning as described above.
- ear portions 312 of the present invention will have side panel assembly receiving ear portion configurations 312 a and 312 d , and non-receiving ear portion configurations 312 b and 312 c as will be described later.
- the ear tab forming material 316 is slit and spread, for instance as shown on FIG. 8 at station 210 .
- Lanes 316 a and 316 b of slit and spread ear tab forming material 316 receive the side panel assemblies described in FIG. 19 a , and ultimately become left and right ear segments on a disposable product.
- FIG. 19 a a schematic view of formation of side panel assemblies 320 is shown.
- the formation of side panel assemblies 320 begins with an outer non-woven web material 318 , which is slit and spread into discrete non-woven web portions 318 a , 318 b , 318 c , and 318 d , each of the non-woven web portions also preferably being cut in the cross-machine direction into the preferred size.
- Fastening mechanisms 322 can be tape tabs, covered tape tabs, strips of hook and loop material, continuous hook and loop material, patches of hook and loop material, etc. The fastening mechanisms 322 will be unfastened and refastened about the waist of the user to tighten the disposable garment about the waist.
- the non-woven webs 318 carrying fastening mechanisms 322 are folded over, creating a folded web 318 and folded fastening mechanisms 322 ′.
- the folded fastening mechanisms 322 ′ of web portions 318 a and 318 b will have opposing fastening mechanisms 322 ′ as they will become the right and left hip waist fastening mechanisms, respectively, once placed about the waist of a user (shown later in the process).
- a stretch laminate web 324 is also provided. This too is slit and spread into discrete stretch laminate web portions 324 a , 324 b , 324 c , and 324 d.
- the non-woven web portions 318 a , 318 b , 318 c , and 318 d are bonded to stretch laminate web portions 324 a , 324 b , 324 c , and 324 d respectively, forming the side panel assemblies 320 in four different lanes, 318 a + 324 a , 318 b + 324 b , 318 c + 324 c , and 318 d + 324 d .
- the non-woven web portions 318 a , 318 b , 318 c , and 318 d can be bonded to the stretch laminate web portions 324 a , 324 b , 324 c , and 324 d in any fashion, such as by ultrasonic bonding using a mechanism such as shown in FIG. 16 , by lap seams, by adhesives, fin seams, etc.
- the stretch laminate portions 324 a , 324 b , 324 c , and 324 d can also be folded if desired, or the stretch laminate portions 324 a , 324 b , 324 c , and 324 d in combination with the non-woven web portions 318 a , 318 b , 318 c , and 318 d can all be folded together and again.

- An inner axle 1218 and an outer axle 1220 are coupled to the transfer roll 1214 (or hub 1222 ) and the trim shoes 1212 , respectively.
- the inner axle 1218 and the outer axle 1220 are capable of being operated at different speeds in relation to one another by servo motor (not shown). This difference in speed allows the trim shoes 1212 to rotate faster or slower with respect to the transfer roll 1214 as desired. In use, as will be described later, this speed differential creates a ripping effect by first pulling the combined web 1202 away from the chip 30 as the transfer roll 1214 is rotating faster than the shoe 1212 , then by pulling the chip 1230 away from the combined web 1202 as the shoe 1212 is rotating faster than the transfer roll 1214 .
- FIG. 64 a two-dimensional representation of the trim shoe 1212 and transfer roll 1214 of FIG. 63 is shown.
- vacuum channels 1217 communicate with vacuum ports 1216 on both the trim shoe 1212 and transfer roll 1214 to maintain control of the chip 1230 and combined web 1202 .
- different rotational speeds of the trim shoe 1212 and transfer roll 1214 will cause a ripping effect by first pulling the web 1202 away from the chip 1230 as the transfer roll 1214 is rotating faster than the shoe 1212 , then by pulling the chip 1230 away from the combined web 1202 as the shoe 1212 is rotating faster than the transfer roll 1214 .
- FIG. 65 is a cross sectional view of a trim shoe 1212 and transfer roll 1214 of the present invention.
- vacuum is communicated to ports 1216 through channels 1217 , which are coupled to a source of vacuum (not shown).
- Rotation of the outer axle 1220 which is coupled to the shoe 1212 , causes rotation of the shoe 1212 .
- the inner axle 1218 is coupled preferably to hub 1222 and to transfer roll 1214 .
- FIGS. 66-71 a sequence is shown of the trim removal system 1210 removing chips 1230 and discharging them, and then the system 1210 returning to its initial position to remove more chips 1230 from the next segment of web 1202 .
- FIGS. 72-75 are plan views of the position of the chips 1230 relative to the web 1202 at the positions associated with FIGS. 66-68 respectively, demonstrating the ripping effects of the present invention.
- FIG. 66 a schematic view of the system 1210 is shown receiving an infeed web 1202 .
- die and anvil system 1226 is shown rotating to engage the web 1202 and cut from it chips 1230 (not apparent in this view), as is well known in the art.
- the die of the die and anvil system 1226 is susceptible to wear and tear and requires replacement once the die dulls to an unacceptable condition.
- the trim shoe 1212 can be seen in an initial chip engaging position, aligned to receive the chip 1230 of the web 1202 onto the shoe 1212 , which, as described previously, will be urged against the surface of the shoe 1212 by vacuum ports 1216 .
- the trim shoe 1212 will be seen to be rotating about outer axis 1220 .
- a discharge chute 1228 is shown for ultimately receiving waste chips 1230
- an outfeed conveyor 1240 is provided for receiving the web 1202 with the chip 1230 removed, for further processing and manufacturing steps in the composition of the disposable garments, as desired.
- Inner axle 1218 is preferably operated at a first continuous speed, rotating hub 1222 and transfer roll 1214 at a continuous speed, consistent with the infeed speed of the web 1202 .
- the outer axle 1220 , and associated shoes 1212 are rotated at the same speed as the inner axle 1218 .
- the position of the chip 1230 relative to the web 1202 is shown in FIG. 72 for the initial chip engaging position. In this position, the anvil and die 1226 has created a sever, but the chip 1230 and web 1202 could remain somewhat coupled depending on the sharpness of the die 1226 .
- the severing method shown in the figures, particularly the severing trim removal device 1210 is just one method of forming the novel products of the present invention, other methods of severing and/or trim removal may be used.
- the outer axle 1220 , and associated shoes 1212 are toggled slower than inner axle 1218 to allow the web 1202 to be ripped from the chip 1230 at the leading edge of the chip 1230 in the machine direction. It is apparent in this view that the distance between the trailing edge of the shoes 1212 has become closer to the leading edge of the transfer roll 1214 . This ripping is caused by the main web 1202 being ripped away from the chip 1230 at the leading edge of the chip 1230 as is shown in associated FIG. 73 .
- the outer axle 1220 is toggled equal to and then faster than the inner axle 1218 , to allow the chips 1230 to rip from the web 1202 at the trailing edge of the chips 30 as is shown in associated FIG. 74 .
- the chip 1230 will be removed from the web 1202 by ripping first the main web 1202 away from the chip 1230 at the leading edge of the chip 1230 , and next by ripping the trailing edge of the chip 1230 from the web 1202 .
- the outfeed conveyor 1240 is provided for receiving the web 1202 with the chip 1230 removed as shown in FIG. 75 , for further processing and manufacturing steps in the composition of the disposable garments, as desired.
- the vacuum of the transfer roll 1214 can be turned off at this point to allow for release of the web 1202 to the conveyor, for instance in accordance with application Ser. No. 11/141,552, entitled “High Speed Vacuum Porting” which is incorporated herein by reference.
- the chip 1230 is discharged into a discharge chute 1228 , which is preferably vacuum assisted, although other collection means would satisfactorily accomplish the function of collecting waste chips 1230 . It is noted that vacuum is allowed to turn off of the shoes 1212 to allow the chips 1230 to release into the chute 1228 . Alternatively, a vacuum in the chute 1228 could simply be provided that is stronger than the vacuum applied to the shoes 1212 .
- the die of the die and anvil system 1226 in the above described trim removal apparatus may be replaced by a perforating apparatus.
- the perforating apparatus preferably forms the chips 1230 on the web 1202 but does not completely sever the chips 1230 from the web 1202 .
- the perforated chips 1230 perforated could then be removed from the web 1202 in the same manner described above.
- the perforating apparatus may take any form known in the art including, but not limited to, a perforating die roll.

- The present invention relates to disposable hygiene products and more specifically, to methods and apparatuses for processing disposable hygiene products. More specifically, the invention relates to cutting and applying segments of one web to attach to a disposable diaper.
- The invention disclosed herein also relates to apparatus and methods for waste reduction. Generally, diapers comprise an absorbent insert or patch and a chassis, which, when the diaper is worn, supports the insert proximate a wearer's body. Additionally, diapers may include other various patches, such as tape tab patches, reusable fasteners and the like. The raw materials used in forming a representative insert are typically cellulose pulp, tissue paper, poly, nonwoven web, acquisition, and elastic, although application specific materials are sometimes utilized. Usually, most of the insert raw materials are provided in roll form and unwound and applied in assembly line fashion. As in many manufacturing operations, waste minimization is a goal in web processing applications, as products having spliced raw materials cannot be sold to consumers. Indeed, due to the rate at which web processing machines run, even minimal waste can cause inefficiencies of scale.
- In present systems, waste materials are recycled. However, the act of harvesting recyclable materials from defective product is intensive. That is, recyclable materials are harvested only after an identification of a reject product at or near the end of a process. The result is that recyclable materials are commingled, and harvesting requires the extra step of separating waste components. Therefore, it is beneficial to use up all of incoming rolls, so that a portion of the incoming rolls do not become waste. That objective is accomplished with the present invention
- When manufacturing hygiene products, such as baby diapers, adult diapers, disposable undergarments, incontinence devices, sanitary napkins and the like, a common method of applying discrete pieces of one web to another is by use of a slip-and-cut applicator. A slip-and-cut applicator is typically comprised of a cylindrical rotating vacuum anvil, a rotating knife roll, and a transfer device. In typical applications, an incoming web is fed at a relatively low speed along the vacuum face of the rotating anvil, which is moving at a relatively higher surface speed and upon which the incoming web is allowed to “slip”. A knife-edge, mounted on the rotating knife roll, cuts off a segment of the incoming web against the anvil face. This knife-edge is preferably moving at a surface velocity similar to that of the anvil's surface. Once cut, the web segment is held by vacuum drawn through holes on the anvil's face as it is carried at the anvil's speed downstream to the transfer point where the web segment is transferred to the traveling web.
- Continual improvements and competitive pressures have incrementally increased the operational speeds of disposable diaper converters. As speeds increased, the mechanical integrity and operational capabilities of the applicators had to be improved accordingly.
- The present invention allows for square, and non-square, and preferably trapezoidal, ear webs to be applied to a traveling web, with zero or minimized waste present in the incoming ear web. Zero material is wasted due to the geometry of the chosen ear pattern and its downstream processing.
- An ear is a component of a diaper that is grasped and pulled around the waist of a wearer. Typically, ears are secured to the diaper at a first end, and a second free end is typically equipped with securing means, such as a pressure sensitive adhesive, or hook and loop material. As a user grasps an ear and pulls the ear, elasticity provided about the waist region of the diaper allows the free end to be snugly pulled about the waist of a wearer. Ears can be rectangular or made of irregular shapes.
- The present invention provides a process wherein a rotary knife or die, with one or more cutting edges, turns against and in coordination with a corresponding cylinder to create preferably trapezoidal ears. Ear material is slit into two lanes, one for a left side of a diaper and the other for a right side of a diaper. Fastening tapes are applied to both the right and the left ear webs. The ear material is then die cut with a nested pattern on a synchronized vacuum anvil.
- The resulting discrete ear pieces however, due to the trapezoidal pattern of the ears, alternate between a correct orientation and an incorrect (reversed) orientation. The reversed ear is required to be rotated 180° into the correct orientation such that the ears and associated tape present a left ear and a right ear on the diaper.
- To accomplish the reversal of the ear pattern, discrete ear pieces are picked up at the nested ear pitch by an ear turner assembly that will expand to a pitch large enough for ears to be unnested and allow clearance for every other ear to be rotated. The rotated ears are then unnested and into the correct orientation.
- Two ear turner assemblies can be provided, to rotate every other ear applied to the right side of the product, and every other ear applied to the left side of the product. In this manner, for a single product, one of the two ears will have been rotated 180°.
- Ear application to a chassis web can be by a bump method (described later) with intermittent adhesive applied to the chassis web or can be by vacuum transfer.
- The present invention also allows for two side panel assemblies, including fastening mechanisms, to be attached to two ears, the side panel assemblies attached in a pre-folded condition. Two more ears can be coupled to a chassis web to create a front panel to wear about the waist of a user.
- The present invention also allows for chips of material to be removed from the ears to provide a diaper with contoured leg openings. In one embodiment, the chips may be removed from the ears before the ears are attached to the chassis web. In an additional embodiment the chips may be removed from the ears after the ears are attached to the chassis web. In an additional embodiment the chips may be removed from the ears and a portion of the chassis web removed after the ears are attached to the chassis web.

- Referring to the drawings there is seen in
FIG. 1 a diagrammatic illustration of a prior art process for applying tabs to webs in a diaper making process, to result in an intermediate product shown inFIG. 2 . The present invention can use this prior art method of affixing thesegments 12 to theweb 10, with a different anvil, thenew anvil 114 described below.Web 10 is a composite material used in formation of diapers which is generally formed of various layers of material such as plastic back sheets, absorbent pads and nonwoven top sheets. A series ofears 12 are applied toweb 10. In the illustrated process ofFIG. 1 , arotatable vacuum anvil 14 is used to supply theears 12 toweb 10.Anvil 14 has internally reduced air pressure or vacuum (not shown), and a plurality ofopenings 24 are provided through its surface to enable suction of thetab segments 12 against theanvil surface 14. A web of the eartab forming material 16 is fed byrollers anvil surface 14 where it is cut into segments by arotary knife 18. - The surface of the
anvil roll 14 can have vacuum holes 24 on its smooth surface. In a typical configuration of a slip-and-cut applicator, there is a pattern of vacuum holes 24 distributed to evenly draw the entering web onto the surface ofanvil 14 and thence into the cut point where theknife edge 18 engages theanvil 14. - It can be seen from
FIG. 1 that in the prior art, the infeed of the eartab forming material 16 can be at a first speed (withindividual ears 12 spaced together), after which the individual ears gain speed to the speed of theanvil 14. Typical infeed speeds could be 120 mm/product for the infeed, while anvil speeds could be 450 mm/product on the anvil. This transition from the slower first speed to the quicker second speed takes place at the cut point, the eartab forming material 16 slipping on theanvil 14 until cut. However, immediately at the transition cutpoint 18 from the slower speed to the faster speed, it is desired to place vacuum on the ears because centrifugal force would try to throw the ears off of thevacuum anvil 14. -
Ear webs 16 can be comprised of two portions, 12 a and 12 b, as shown inFIG. 2 .Segment 12 a is more specifically referred to as the tab section of theear 12,segment 12 b is the ribbon section of theear 12. - Alternatively, the ears can comprise a trapezoidal shape, as shown in
FIGS. 6, 7A and 7B , which will be described later. The trapezoidal shape ofFIGS. 7A and 7B is particularly advantageous for zero waste applications, where it is desired to reduce or eliminate the scrapping of raw material. In another zero-waste technique, two parallel series of alternatingear webs 16 with ribbon sections of theear 12 could be created by mirroring theweb 16 as shown inFIG. 3 and placing the mirrored web down one/half of an ear length (not shown). - Referring now to
FIG. 4 , a front view of ananvil roll 114 is shown carrying ear forming material 16 (and later, individual ears 12) in phantom. Theanvil roll 114 is preferably formed with twovacuum portions 116 separated by acenter groove portion 118. Thevacuum portions 116 are preferably mirror images of each other. Theanvil roll 114 is symmetrical about a center plane through its circumference. Eachvacuum portion 116 contains several circumferential rows of circular vacuum holes 24. Eachvacuum portion 116 may also contain acircumferential groove 120 with an additional circumferential row of vacuum holes 24 located in thecircumferential groove 120. - Still referring to
FIG. 4 , two diametrically opposed anvil pockets 122 and two diametrically opposed pairs ofear retaining portions 124 are shown. The ear retaining portions can be created as inserts, with different vacuum patterns applied as the user deems necessary. Eachanvil pocket 122 is a groove which extends across the face of theentire anvil roll 114. Oneear retaining portion 124 is located on each of thevacuum portions 116. Eachear retaining portion 124 has an earvacuum hole pattern 126 made of a plurality of vacuum holes 24 located at or near the surface of the anvil roll 144. A plurality of rows of vacuum holes 24 can be employed, each row having a plurality of vacuum holes 24, although more or less than those configurations or patterns shown can be used. - Referring now to
FIG. 5 , a schematic view of a nested zero waste ear applicator device and methods of the present invention are shown. Components of this ear applicator include aweb slitter 210, which processes incomingear web material 16 into two parallel paths (not shown from this view). After being slit, ear web material is processed bytape applicator 220, which can add tape to the ears for securing theears 12 about the waist of a wearer. - After slitting and application of the tape to the
ear web 16, an ear die is used to cut theear web 16 into the pattern shown inFIG. 7A . Theear material 16 is die cut with a nested pattern on a synchronized vacuum anvil/diecombination 230/232 and carried by rotation or otherwise to anear turner assembly 200. - Referring still to
FIG. 5 , the cutting edges of the ear dies 230 turn against and in coordination with acorresponding anvil 232 to create preferably trapezoidal ears. It is noted that as shown inFIG. 6 ,ears 12 having different heights, H1 and H2, can be produced in this configuration by speeding up or slowing down the infeed rate ofmaterial 16 into the anvil/diecombination 230/232. In this manner, more or less slip is allowed onmaterial 16 prior to cutting, resulting in longer or shorter ears. - Because the
ear material 16 has already been slit into two lanes, one for a left side of a diaper and the other for a right side of a diaper, it is noted that two parallel ear dies 230 are used to produce the pattern shown inFIG. 7A to theslit web 16, but because of the side vantage point ofFIG. 5a only one of the lanes is visible if more than one is desired. - The resulting discrete ear pieces however, due to the trapezoidal pattern of the ears shown in
FIG. 7A , alternate between a correct orientation A and an incorrect (reversed) orientation B. The reversed ears B are required to be rotated 180° into the correct orientation A such that the ears and associated tape present a left ear and a right ear on the diaper, such as that shown onFIG. 7B . In correct orientation A, such as shown inFIG. 7B , the shorter of the parallel edges of the trapezoid will face toward an outside, left for the left side, and right for the right side. This geometry is desirable to accommodate the legs of the wearer when theears 12 are pulled about the waist of the wearer. - To accomplish the reversal of the ear pattern, discrete ear pieces are picked up at the nested ear pitch by an ear turner assembly 200 (see
FIGS. 5 and 8 ) that has a series ofpucks 234 that travel radially from a minimal radius R1 (and therefore a minimal tangential speed) to a maximal radius R2 (and therefore a maximal tangential speed) at a depositional site. The difference between R1 and R2 is such that individual pucks 235 can be unnested and allow clearance (in the radial direction from adjacent pucks 234) for every other ear to be rotated, as will be described later in relation toFIGS. 10a and 10b . The rotated ears are then unnested and into the correct orientation and brought to the proper speed for deposition onto either an additional vacuum drum (as shown onFIG. 5a ) and subsequently ontoweb 10 orhigh vacuum drum 250. - Referring to
FIG. 7A , two lanes ofears 12 are depicted, 16A and 16B representing right and left ears intended for a product. The longest side of theears 12 is intended for attachment toweb 10, so because trapezoids are desirable, every other trapezoid in each lane will require 180° rotation to allow the desired side (for example, the longest side) of theear 12 to be confronted with attachment toweb 10. All of the “B” labeledears 12 onsupply 16A will be rotated 180° into an A position. All of the “B” labeledears 12 onsupply 16B will be rotated 180° into an A orientation position to achieve the desired depositional orientation shown inFIG. 7B . - It is noted that ear configurations can vary as shown in
FIGS. 7C-7F . InFIGS. 7C and 7D , wavy or curved ear patterns are shown. InFIG. 7E , a square pattern is shown. InFIG. 7F , a trapezoidal pattern is shown. Chips may be cut out in any shape of ear patterns, such as such inFIG. 7F . The chips can be of any shape or size and can be positioned either on edges of the ears or on the interior of the ears. - Referring now back to
FIG. 5 , following rotation of every “B” labeledear 12, each ear is deposited ontovacuum drum 240, rotated and picked up byhigh vacuum drum 250.Vacuum drum 240 is a size change roll that matches pitch.Vacuum drum 240 can also be used as a roller, in conjunction with or replacingroller 260,FIG. 16 . - Because the
ears 12 need to be sped up to match the speed ofchassis web 10, the rotation ofhigh vacuum drum 250 is quicker than that ofvacuum drum 240. The higher vacuum indrum 250 relative to drum 240 allows theears 12 to be snatched or grabbed at the higher rotational speed present indrum 250. - Referring now to
FIG. 5a , a schematic view of a nested zero waste back ear applicator device and methods of the present invention is shown, with an alternate web path configuration. - Referring now to
FIG. 8 , a perspective schematic view of the nested zero waste back ear applicator device and methods of the present invention is shown. As can be seen, twoear turner assemblies 200R (right) and 200L (left) are provided, to rotate everyother ear 12 applied to the right side of thechassis web 10, and everyother ear 12 applied to the left side of thechassis web 10. In this manner, for a single product, one of the two ears will have been rotated 180°. As can be seen fromFIG. 8 , two types of pucks are provided,non-rotating pucks 234A androtating pucks 234B. Thenon-rotating pucks 234A carry the “A” ears shown inFIG. 7A , or the ones that do not require rotation. Therotating pucks 234B carry the “B” ears shown inFIG. 7A . As theear turner assemblies ears 12 are picked up from the ear die/anvil station 230/232 and rotate about therotator 200, while everyrotating puck 234B also rotates radially during rotation of therotator 200, as will be described later. - The
ears 12 are then deposited ontochassis web 10 and bonded thereto, for instance byultrasonic bonding ring 252, where the resulting product is sent downstream for further processing. - Referring now to
FIG. 8a , a perspective schematic view of the nested zero waste back ear applicator device and methods of the present invention with an alternate web path configuration is shown. This is the preferred embodiment of the vacuum drum/ultrasonic bonding ring 250/252 in relation to thevacuum drum 240. In this configuration, the ears are ultrasonically bonded to thechassis web 10 between the vacuum drum/ultrasonic bonding ring 250/252 and thevacuum drum 240 as thechassis web 10 travels from right to left as pictured. - Referring now to
FIG. 9 a side view of the earturner assembly device 200 is shown. The earturner assembly device 200 used to rotate alternating ears, again with theentire device 200, rotating about a central axis, and eachpuck 234 traveling radially from a minimal radius R1 to a maximal radius R2 at a depositional site during rotation, and then back to the minimal radius R1. The difference between R1 and R2 is such that individual pucks 235 can be unnested and allow clearance for every other ear to be rotated. Comparing the During rotation from the R1 to the R2 position, rotatingpucks 234B undergo not only the increase in radius, but also undergo 180° rotation about an axis perpendicular to the central axis. This can be performed preferably with a screw operation (reference letter S,FIG. 12 ). During rotation from the R2 position back to the R1 position, therotating pucks 234B rotate back through their 180° rotation to get to their initial position by use of a yankee screw, which is capable of both advancing and retracting thepucks 234B, and rotating thepucks 234B, upon driving the shaft of the yankee screw inward and outward radially. - Referring now to
FIG. 10a , a front view of the earturner assembly device 200 used to rotate alternating ears is shown. As can be seen, thepucks 234 are each equipped withvacuum voids 236 through which a vacuum is pulled, retaining ears on therotator device 200 through their rotation (radially rotating for every ear, radially and axially rotating for every other ear) until deposition. As can be seen, thepucks 234 are can be roughly trapezoidal in shape to roughly match the shape of theears 12. It is also seen from this view that thenon-rotating pucks 234A remain in their axial non-rotated position relative to therotating pucks 234B, which rotate from their initial position nested between twonon-rotating pucks 234A, and back. - Referring now to
FIG. 10B , an alternate shape of thepucks 234 is shown. InFIG. 10A , thepucks 234 are configured to receive wavy shaped ears as described earlier. InFIG. 10B , thepucks 234 are configured to receive trapezoidal shaped ears as described earlier. It is preferable to configure thepucks 234 to match the desired ear pattern. - Referring now to
FIG. 11 , a perspective view of the two earturner assembly devices pucks 234. In this sense, the rotation of thepucks 234 is described in currently pending U.S. application Ser. No. 11/244,387, which is incorporated herein by reference. A front view of this configuration is shown inFIG. 13 and a side view inFIG. 14 . - Referring now to
FIG. 12 a mechanism for rotating pucks 234 b is shown. There, it is seen that screws 236 are provided such that movement of thepucks 234B away from the center axis simultaneously causes rotation ofpuck 234B. Aradially traveling coupling 238 couples the puck with thescrew 236, and when the threads of the screw are engaged with theradially traveling coupling 238, rotation is caused. -
FIG. 15 is a cross-sectional view of the earturner assembly device 200 used to rotate alternating ears along the line shown inFIG. 12 . Particularly, screws 236 are operably coupled with pucks orrotator assemblies 234. By rotation of thescrew 236,pucks 234 are moved along a radial line in relation to shaft turner 246.Vacuum manifold 244 is provided to commute vacuum to thepucks 234 and ultimately to hold theears 12 in place.Ear turner cam 242 is provided for rotative purposes. - Referring now to
FIG. 16 , a front view of arotatable vacuum wheel 114,ultrasonic bonding ring 252, andvacuum pattern 124 used for pitch changing ears from a slower web and applying and bonding theears 12 sandwiched betweenroller 260 and theanvil 114 to a faster moving chassis web is shown. - In this embodiment, the
aggressive vacuum pattern 124 onhigh vacuum drum 250 will have withdrawnears 12 fromvacuum drum 240. This step follows the rotation of the “B” ears as described above. Thechassis web 10 is fed in between theroller 260 and thehigh vacuum drum 250. Theultrasonic bonding ring 252 couples theears 12 with the chassis web 10 (refer toFIG. 5 ). - Referring now to
FIG. 17 , a schematic view of the nested zero waste backear applicator device 200 an alternate embodiment of a means for applying theear 12 to thechassis web 10 is shown. Instead of the vacuum porting system as previously described, a protuberance carrying rotatable body 274 is urged against thechassis web 10, as disclosed in U.S. Pat. No. 6,475,325, which is incorporated herein as if fully set forth. The disclosure of U.S. Pat. No. 6,475,325 is referred to as the “bump transfer” method. In this embodiment intermittent adhesive is applied to thechassis web 10 atstation 270. The intermittent adhesive is applied at intervals to make contact withears 12 carried by rotatingbody 200. The protuberance carried by body 274 urges thechassis web 10 towards anear 12 carried by apuck 234. With theear 12 coupled with the chassis web, the coupled material is processed byfinal bonding station 272, after which the ear/chassis combination is sent downstream for further processing as desired. - Referring generally to
FIGS. 18-28 , schematic and plan views are presented of a novel disposable garment configuration using methods of performing nested zero waste back ear application including a multi-component ear portion fabrication, bonding and folding. The embodiments ofFIGS. 18-28 are particularly well suited for formation of what is called in the industry as an adult-sized diaper. - One difficulty with adult-sized products is sheer size. The products are required to be quite large (for instance, 32″ wide in a non-stretched condition) in the waist section to fit about the waist of an adult. However, the adult-sized products are typically shipped in packages about 8″ wide, so the products require folding, particularly at the waist zone where the product is the widest, in order to be compactly packaged and shipped.
- The prior art often employed a Z-fold of ears to get the waist band down to size. For instance, the
ears 12 applied toweb 10 shown inFIG. 2 would have to be folded as to not extend much past the profile of thechassis web 10. This assists both processing of the web as it avoids flying parts, but also assists packaging and transport of the material. - The embodiments of
FIGS. 18-28 show construction of an ear segment that can be formed of multiple pieces, as opposed to the one-piece ears of the prior art (see, e.g.,ears 12 ofFIG. 2 ). This allows both creation of a contoured multi-piece ear segment, as well as assembly of at least portions of the ear segment in a pre-folded condition. - Referring now to
FIG. 18 , a plan view of an eartab forming material 316 is shown entering the system similarly positioned tomaterial 16 shown onFIG. 8 or 8 a. Preferably the ear tab forming material (or wing) 316 is a non-woven continuous web of material which is ultimately formed into shapedear portions 312.Shaped ear portions 312, as described with respect toFIGS. 7a-7f , can take on different shapes, and can have correct original orientation, or orientation that requires re-phasing or turning as described above. - In a preferred
embodiment ear portions 312 of the present invention will have side panel assembly receivingear portion configurations ear portion configurations - Referring to
FIG. 19 , the eartab forming material 316 is slit and spread, for instance as shown onFIG. 8 atstation 210.Lanes tab forming material 316 receive the side panel assemblies described inFIG. 19a , and ultimately become left and right ear segments on a disposable product. - Referring now to
FIG. 19a , a schematic view of formation ofside panel assemblies 320 is shown. The formation ofside panel assemblies 320 begins with an outernon-woven web material 318, which is slit and spread into discretenon-woven web portions - To each of the discrete
non-woven web portions more fastening mechanisms 322 are applied. Fasteningmechanisms 322 can be tape tabs, covered tape tabs, strips of hook and loop material, continuous hook and loop material, patches of hook and loop material, etc. Thefastening mechanisms 322 will be unfastened and refastened about the waist of the user to tighten the disposable garment about the waist. - Next, the
non-woven webs 318 carryingfastening mechanisms 322 are folded over, creating a foldedweb 318 and foldedfastening mechanisms 322′. This causes the combination of thenon-woven web 318 and thefastening mechanisms 322 to be narrower than the discretenon-woven web portions fastening mechanisms 322′ ofweb portions fastening mechanisms 322′ as they will become the right and left hip waist fastening mechanisms, respectively, once placed about the waist of a user (shown later in the process). - In addition to the discrete
non-woven web portions stretch laminate web 324 is also provided. This too is slit and spread into discrete stretchlaminate web portions - Next, the
non-woven web portions respective fastening mechanisms 322′, are bonded to stretchlaminate web portions side panel assemblies 320 in four different lanes, 318 a+324 a, 318 b+324 b, 318 c+324 c, and 318 d+324 d. Thenon-woven web portions laminate web portions FIG. 16 , by lap seams, by adhesives, fin seams, etc. - The
stretch laminate portions stretch laminate portions non-woven web portions - Referring now to
FIG. 20 , a plan view of a side-panel assembly 320 coupled to the ear tab forming material is shown. In a preferred embodiment, side-panel assembly 320, and particularly thepanel 320 havingconfiguration 318 a+324 a (fromFIG. 19 ), is slip-cut onto the top oflane 316 a, and particularly slip-cut and coupled toear portion configuration 312 a. - Similarly, side-
panel assembly 320, and particularly thepanel 320 havingconfiguration 318 b+324 b (fromFIG. 19 ), is slip-cut onto the bottom oflane 316 a, and particularly slip-cut and coupled toear portion configuration 312 d. - In
lane 316 b, side-panel assembly 320, and particularly thepanel 320 havingconfiguration 318 c+324 c (fromFIG. 19 ), is slip-cut onto the top oflane 316 b, and particularly slip-cut and coupled toear portion configuration 312 d. - Similarly, side-
panel assembly 320, and particularly thepanel 320 havingconfiguration 318 d+324 d (fromFIG. 19 ), is slip-cut onto the bottom oflane 316 b, and particularly slip-cut and coupled toear portion configuration 312 a. - The
panels 320 can be coupled to the slit and spread eartab forming material 316 in any fashion. Preferred methods may include ultrasonic bonding, adhesive bonding, heat, etc. Also, the coupling between thepanels 320 and the eartab forming material 316 could be contained in or be a portion of a larger laminate involving other materials and bonds. - Next, referring now to
FIG. 21 , the side-panel assemblies 320 have been folded over (or under) the eartab forming material 316, to conform to, and preferably be narrower than, theear portions 312 oflanes - It is desirable to process the combination of the side-
panel assemblies 320 temporarily staked to the eartab forming material 316 together, so that components do not become entangled in the machinery during processing. It is also desirable so that packaging can be accomplished orderly and uniformly. Preferably, the side-panel assemblies 320 are temporarily staked to the eartab forming material 316. The temporary staking can be done, for instance but not by way of limitation, by a light application of adhesive, by a light compression bond, by a light compression bond assisted by slight penetration of pins through the layers, by a weak ultrasonic bond, or by other types of temporary and light bonds may be employed. - Referring now to
FIGS. 22-25 , after the side-panel assembly 320 has been coupled to the eartab forming material 316, and after the side-panel assembly 320 has been folded, the side panel and wing assembly 320+316 is treated as theear 12 was treated with reference toFIGS. 1-17 . For instance, theside panel assembly 320 andear tab 316 can be re-phased (FIGS. 22-23 ), then die-cut, repitched, and rotated (FIGS. 24-25 ). - In particular, the
ear portion configurations FIG. 8 or 8 a onto the machine shown onFIG. 9 , which would die-cut, re-pitch and rotate every other wing assembly as shown onFIG. 24 . - The 316 a lane would be treated by one of the
ear turner assemblies 200R (right) or 200L (left) ofFIG. 11 , and the 316 b lane would be treated by the other of the 200R or 200L ear turner assemblies. - As a result, and as shown on
FIG. 25 , every other of theear portion configurations - Referring now to
FIG. 26 , theears 312 andside panels 320 have been properly oriented and re-phased such that rightfront ear 312 b (front of product, noside panel 320 attached) and its associated right backear 312 d (back of product, with aside panel 320 attached and folded) are mirrored with leftfront ear 312 c (front of product, noside panel 320 attached) and its associated left backear 312 d (back of product, with aside panel 320 attached and folded). Theseears 312 andside panels 320 are introduced to and coupled with web 10 (or chassis top sheet), typically a composite material used in formation of diapers which is generally formed of various layers of material such as plastic back sheets,absorbent pads 340 and nonwoven top sheets (visible inFIGS. 27 and 28 ). - Referring now to
FIG. 27 , the next step is to fold theears side panels 320 down, in overlapping fashion, such that either one oflanes ears side panels 320 are folded into, and narrower than, the width of thechassis assembly 10 in the cross-machine direction. -
FIG. 28 is an in-use plan view of an inventive disposable product formed by the methods of the present invention. As can be seen, theears side panels 320, which had been previously folded onto theears 312. A user can place theabsorbent pad 340 in the crotch region and couple thefastening mechanisms 322 of theside panels 320 about the waist, to reach the front ofears - Referring now to
FIGS. 29-42 , schematic and plan views of methods of assembling a disposable product, including forming a nested zero waste ear to a nested zero waste wing portion, attaching ear and wing portions to a chassis top sheet, and folding the product to form a folded diaper are shown. In general, the product shown inFIGS. 29-42 is formed by cutting (preferably die cutting) a web (preferably a stretch laminate or non-woven) to form an ear, alternately turning and attaching the ear to a wing, fold and stack the ear to the wing, die cutting the wing, alternately turning and attaching wing and ear assembly to a chassis, folding and stacking a wing to a chassis non-woven. - Referring to
FIG. 29 , the process begins with a web portion 1000 (preferably non-woven), introduced into the system, which, as shown inFIG. 30 , is split and spread into four lanes ofnon-woven webs FIG. 19a . Instead of the rectangular cuts created of the discretenon-woven web portions FIG. 19a , theears 1012 shown in formation of the ear ofFIGS. 29-32 can be cut of a zero-waste trapezoidal configuration as shown, or other zero waste rectangular or non-rectangular configurations (such as inFIGS. 7a-7f ). - As shown in
FIG. 31 ,tapes 1022 are applied to the non-woven (similar to 322 and 322′ ofFIG. 19a ) and folded. Next, referring toFIG. 32 theears 1012 are die cut, repitched and rotated, in the fashion shown, for instance utilizing a machine depicted inFIGS. 11-14 . The final orientations showntapes 1022 folded in-line of theears 1012, and the ear orientations after folding resulting in four different ear orientations, 1012 a, 1012 b, 1012 c, and 1012 d. - In
orientation 1012 a, thetapes 1022 are on the top side, with the long side (opposite the top side) on the bottom side. Inorientation 1012 b, thetapes 1022 are on the bottom side, with the long side (opposite the bottom side) on the top side. Similar rotation and resulting orientations are shown with respect to 1012 c and 1012 d. - Referring to
FIGS. 33 and 34 , awing web 1040, preferably non-woven for receiving foldedtapes 1022 coupled toears 1012 is shown, withwing web 1040 slit and spread such as inFIGS. 18 and 19 , and the ear after cutting, repitching and rotation, is introduced to the wing web as shown inFIG. 35 (similar toFIG. 20 above). - As can be seen in
FIG. 35 , the foldedtapes 1022 coupled toears 1012 are introduced in the fashion shown, with the 1042 lane of wing web material receiving foldedtapes 1022 coupled toears 1012 inorientation 1012 a coupled to awing web portion 1042 b, such that the short edge of the trapezoid in the cross-machine direction (left to right) receives the long edge of theears 1012 from the 1012 a orientation. The short edge ofwing web portions 1042 a in the cross-machine direction receives the long edge ofear 1012 in the 1012 b orientation. The configuration that results is pictured inFIG. 35 , also regardinglane 1044 of wing web material with the short portions of portions 1040 a in the cross-machinedirection receiving ears 1012 in the 1012 c orientation on the long side of the 1012 c orientation in the cross-machine direction, and similarly withportions 1044b receiving ears 1012 in the 1012 d orientation as shown. - All of the ears are then folded down as shown in
FIG. 36 , such thatportions b host ears 1012, whileportions Portions host ear portions 1012 oriented in the 1012 c and 1012 d orientations, respectively. - In
FIGS. 36-40 , the process continues as shown, similar to the process described above in relation toFIGS. 21-27 . A representative product as shown inFIG. 41 is formed thereby, its cross section shown inFIG. 42 . - Referring to
FIG. 37 , it is seen that every other of the pair of elements from the 1042 lane are rotated. The 1042 d and adjacent 1042 a elements are not rotated, while the 1042 b and adjacent 1044 c are rotated 180° into sequence. Similarly with respect tolane 1044,elements elements - What can be seen in
FIG. 38 is that the elements have been positioned properly to be deposited onto a chassis web (preferably pre-formed with the elements such as an absorbent core, top sheet and back sheet as shown, but not labeled in the remaining figures). All of the folding of theear portions 1012 on the wing portions 104 s are to the top oflane 1042 and the bottom oflane 1044, so that when a chassis portion is coupled betweenlanes FIG. 39 , thewings 1042 a carryingears elements elements - Referring now to
FIG. 40 , theelements 1042 a (carryingear 1012 a), 1042 b (carryingear 1012 b), 1042 c and 1042 d, as well as 1044 a (carryingear 1012 d), 1044 b (carryingear 1012 c), 1044 c and 1044 d are folded over to be in-line with thechassis web 10. - Referring now to
FIGS. 43-60 , and additional embodiment is formed using the procedure shown therein. - Referring to
FIG. 43 , a laminate is shown after slit stretching (501-504), and four lanes ofhook material 505 are shown below.

FIG. 60 . - It is contemplated that it may be desirable to provide a disposable product with a contoured or
curved leg opening 1200 by trimming a portion of a combinedweb 1202 afterwings 1042 a-1042 d,1044 a-1044 d have been placed on thechassis web 10 as shown inFIGS. 61 and 62 . For illustrative purposes, the combinedweb 1202 and resultingdisposable garment 1204 ofFIGS. 39-41 are shown inFIGS. 61 and 62 , however, it should be understood that the methods described herein may be utilized on any combined web. Preferably, the combinedweb 1202 includes achassis web 10, a plurality ofear carrying wings non-ear carrying wings FIG. 39 . - Preferably, a portion of the
ear carrying wings non-ear carrying wings garment 1204 may be removed to create a contoured shape, as shown inFIG. 61 . However, it is also contemplated that a portion of thechassis web 10 between theear carrying wing non-ear carrying wing FIG. 62 . For example, as shown inFIG. 61 , a portion of the chassis web between a first non-ear carryingwing portion 1042 d and a first ear carryingwing portion 1042 b has been removed. - It is contemplated that any means known in the art may be utilized to remove the desired portions of the
wings 1042 a-1042 d,1044 a-1044 d and, if desired,chassis web 10, to create thecontoured leg opening 1200. For example, and not by way of limitation, a knife roll may be utilized to cut thegarment leg opening 1200 to the desired contour. In such a system, a contoured knife roll, with a cutting edge sized and configured to cut theleg opening 1200 to the desired shape would be provided. It is contemplated that both the left 1200 a and the right 1200 b leg opening could be cut at the same time for example with a knife roll with two cutting surfaces, or that a pair of knife rolls, one for theleft leg opening 1200 a and one for theright leg opening 1200 b may be utilized. Each knife roll is provided with an associated anvil, as is well known in the art. In use, the anvil and the knife roll each rotate, with the combinedweb 1202 to be cut between the surface of the knife roll and the anvil. As the knife roll rotates, the cutting edge cuts the combinedweb 1202 against the anvil. - It is further contemplated that a
trim removal system 1210 such as shown inFIG. 63 may be utilized to remove the cut chips from the combinedweb 1202.FIG. 63 shows aninfeed web 1202, and a chip orchips 1230 to be removed therefrom. Atransfer roll 1214 and an associated trim shoe ortrim shoes 1212 are provided to engage the combinedweb 1202 andchips 1230. Preferably, thetrim shoes 1212 are shaped complimentary with thechips 1230.Vacuum ports 1216 are provided on thetransfer roll 1214 and trimshoes 1212 for maintaining the combinedweb 1202 andchips 1230 in close contact with thetransfer roll 1214 and trimshoes 1212. It is noted that other methods of cutting the web, in addition to the particulartrim removal system 1210 may be used to form the products of the present invention. It is also noted that thechip removal system 1210 as pictured, is configured to cut twochips 1230 from theincoming web 1202 at outboard portions of theincoming web 1202.Different shoe 1212 configurations can be used to cut different sized and/or shapedchips 1230, such as thechips 1230 desired to be removed from successiveback ears FIG. 76 , orchips 1230 from between successivefront ears FIG. 76 if desired. CompareFIG. 76 showing chips removed between successivefront ears FIG. 77 , with no chips between front betweenfront ears - An
inner axle 1218 and anouter axle 1220 are coupled to the transfer roll 1214 (or hub 1222) and thetrim shoes 1212, respectively. Theinner axle 1218 and theouter axle 1220 are capable of being operated at different speeds in relation to one another by servo motor (not shown). This difference in speed allows thetrim shoes 1212 to rotate faster or slower with respect to thetransfer roll 1214 as desired. In use, as will be described later, this speed differential creates a ripping effect by first pulling the combinedweb 1202 away from the chip 30 as thetransfer roll 1214 is rotating faster than theshoe 1212, then by pulling thechip 1230 away from the combinedweb 1202 as theshoe 1212 is rotating faster than thetransfer roll 1214. - Referring now to
FIG. 64 , a two-dimensional representation of thetrim shoe 1212 andtransfer roll 1214 ofFIG. 63 is shown. As can be seen,vacuum channels 1217 communicate withvacuum ports 1216 on both thetrim shoe 1212 andtransfer roll 1214 to maintain control of thechip 1230 and combinedweb 1202. From this perspective, it can be seen that different rotational speeds of thetrim shoe 1212 andtransfer roll 1214 will cause a ripping effect by first pulling theweb 1202 away from thechip 1230 as thetransfer roll 1214 is rotating faster than theshoe 1212, then by pulling thechip 1230 away from the combinedweb 1202 as theshoe 1212 is rotating faster than thetransfer roll 1214. -
FIG. 65 is a cross sectional view of atrim shoe 1212 andtransfer roll 1214 of the present invention. As can be seen, vacuum is communicated toports 1216 throughchannels 1217, which are coupled to a source of vacuum (not shown). Rotation of theouter axle 1220, which is coupled to theshoe 1212, causes rotation of theshoe 1212. Theinner axle 1218 is coupled preferably tohub 1222 and to transferroll 1214. - Referring now to
FIGS. 66-71 , a sequence is shown of thetrim removal system 1210 removingchips 1230 and discharging them, and then thesystem 1210 returning to its initial position to removemore chips 1230 from the next segment ofweb 1202.FIGS. 72-75 are plan views of the position of thechips 1230 relative to theweb 1202 at the positions associated withFIGS. 66-68 respectively, demonstrating the ripping effects of the present invention. - Referring now to
FIG. 66 , a schematic view of thesystem 1210 is shown receiving aninfeed web 1202. In this figure, die andanvil system 1226 is shown rotating to engage theweb 1202 and cut from it chips 1230 (not apparent in this view), as is well known in the art. Unfortunately, the die of the die andanvil system 1226 is susceptible to wear and tear and requires replacement once the die dulls to an unacceptable condition. - In this view, the
trim shoe 1212 can be seen in an initial chip engaging position, aligned to receive thechip 1230 of theweb 1202 onto theshoe 1212, which, as described previously, will be urged against the surface of theshoe 1212 byvacuum ports 1216. Thetrim shoe 1212 will be seen to be rotating aboutouter axis 1220. In this view, adischarge chute 1228 is shown for ultimately receivingwaste chips 1230, and anoutfeed conveyor 1240 is provided for receiving theweb 1202 with thechip 1230 removed, for further processing and manufacturing steps in the composition of the disposable garments, as desired. -
Inner axle 1218 is preferably operated at a first continuous speed, rotatinghub 1222 andtransfer roll 1214 at a continuous speed, consistent with the infeed speed of theweb 1202. At this initial chip engaging position shown inFIG. 66 , theouter axle 1220, and associatedshoes 1212, are rotated at the same speed as theinner axle 1218. - The position of the
chip 1230 relative to theweb 1202 is shown inFIG. 72 for the initial chip engaging position. In this position, the anvil and die 1226 has created a sever, but thechip 1230 andweb 1202 could remain somewhat coupled depending on the sharpness of thedie 1226. The severing method shown in the figures, particularly the severingtrim removal device 1210 is just one method of forming the novel products of the present invention, other methods of severing and/or trim removal may be used. - Referring now to
FIG. 67 , theouter axle 1220, and associatedshoes 1212, are toggled slower thaninner axle 1218 to allow theweb 1202 to be ripped from thechip 1230 at the leading edge of thechip 1230 in the machine direction. It is apparent in this view that the distance between the trailing edge of theshoes 1212 has become closer to the leading edge of thetransfer roll 1214. This ripping is caused by themain web 1202 being ripped away from thechip 1230 at the leading edge of thechip 1230 as is shown in associatedFIG. 73 . - Referring now to
FIG. 68 , theouter axle 1220 is toggled equal to and then faster than theinner axle 1218, to allow thechips 1230 to rip from theweb 1202 at the trailing edge of the chips 30 as is shown in associatedFIG. 74 . At this point in the process, thechip 1230 will be removed from theweb 1202 by ripping first themain web 1202 away from thechip 1230 at the leading edge of thechip 1230, and next by ripping the trailing edge of thechip 1230 from theweb 1202. - The
outfeed conveyor 1240 is provided for receiving theweb 1202 with thechip 1230 removed as shown inFIG. 75 , for further processing and manufacturing steps in the composition of the disposable garments, as desired. The vacuum of thetransfer roll 1214 can be turned off at this point to allow for release of theweb 1202 to the conveyor, for instance in accordance with application Ser. No. 11/141,552, entitled “High Speed Vacuum Porting” which is incorporated herein by reference. - Referring now to
FIG. 69 , thechip 1230 is discharged into adischarge chute 1228, which is preferably vacuum assisted, although other collection means would satisfactorily accomplish the function of collectingwaste chips 1230. It is noted that vacuum is allowed to turn off of theshoes 1212 to allow thechips 1230 to release into thechute 1228. Alternatively, a vacuum in thechute 1228 could simply be provided that is stronger than the vacuum applied to theshoes 1212. - The rotational speed of the
shoes 1212 andouter axle 1220, which were first operated at a speed roughly equal toinner axle 1218, rotatinghub 1222 andtransfer roll 1214, initially decreased, or lagged as is shown by comparingFIG. 66 withFIG. 67 . - Next, the rotational speed of the
shoes 1212 andouter axle 1220, increased, or surged relative to theinner axle 1218, rotatinghub 1222 andtransfer roll 1214. - In order to return to the initial chip engaging position, the rotational speed of the
shoes 1212 andouter axle 1220, must again decrease, or lag relative to theinner axle 1218, rotatinghub 1222 andtransfer roll 1214. This lag is apparent by comparingFIG. 68 toFIGS. 69, 70 and 71 . Finally, inFIG. 71 , through one revolution, thesystem 1210 has removed and discharged thechips 1230, discharged theweb 1202 for further processing, and theshoes 1212 have been returned to their initial position to removemore chips 1230 from the next segment ofweb 1202. - It is contemplated that the die of the die and
anvil system 1226 in the above described trim removal apparatus may be replaced by a perforating apparatus. The perforating apparatus preferably forms thechips 1230 on theweb 1202 but does not completely sever thechips 1230 from theweb 1202. Theperforated chips 1230 perforated could then be removed from theweb 1202 in the same manner described above. The perforating apparatus may take any form known in the art including, but not limited to, a perforating die roll. - It is further contemplated that the chips may be removed from the
wings 1042 a-1042 d,1044 a-1044 d prior to attaching thewings 1042 a-1042 d,1044 a-1044 d to thechassis web 10. The chips may be removed from thewings 1042 a-1042 d,1044 a-1044 d, using any means known in the art. For example, thewing web wings 1042 a-1042 d,1044 a-1044 d. - Although the illustrated embodiments of
FIGS. 61, 62 and 76 show a particular configuration or shape of chip being removed from thewings 1042 a-1042 d,1044 a-1044 d andweb 10, is contemplated that the chips removed from thewings 1042 a-1042 d,1044 a-1044 d could take any desired shapes to provide acontoured leg opening 1200. - It is further contemplated that, if desired, chips could be removed from only the
ear carrying wings non-ear carrying wings FIG. 77 shows a chip removed from only theear carrying wings wings 1042 a-1042 d,1044 a-1044 d using any means known in the art, including those means described above. - It is further contemplated that chips may be removed from the
wings 1042 a-1042 d,1044 a-1044 d and thechassis 10 in separate steps as shown inFIG. 78 . For example, chips may be cut from thewings 1042 a-1042 d,1044 a-1044 d in a first step and then cut from theweb 10 in a second step, or vice versa. The chips may be cut from thewings 1042 a-1042 d,1044 a-1044 d andweb 10 using any means known in the art, including those means described above. - Referring now to
FIGS. 79-90 , using the principles of the present invention, several product configuration variations are shown. For instance, it is possible to pre-apply either front 1042 (c or d) or 1044 (c or d) or back 1042 (a orb) or 1044 (a orb) ears to a chassis web using previously known slip/cut techniques (e.g., the slip/cut appliedears 1144 shown inFIG. 79 ), and then use the alternate rotation technique of the present invention to assemble a novel product configuration (see, e.g.,FIG. 79 ). Similarly, it is possible to post-apply either front or back ears to a chassis web using previously known slip/cut techniques, after using the alternate rotation technique of the present invention to assemble a novel product configuration, resulting in a configuration such asFIG. 79 . In this method, the slip/cut technique is used to, for instance, apply each front ear 1144 (both left and rightfront ears 1144,FIG. 79 ), and the alternating rotation technique described previously is used to apply each back ear portion (e.g., 1042 b and 1044 b,FIG. 79 ) - Additionally, it is seen that
extension panels 1012 can be applied or not, if desired (compareFIG. 79 withextension panels 1012 andFIG. 85 , without extension panels 1012) to theback ear portions 1044 if desired, and that thoseextension panels 1012 can be paired with theback ears 1044 with theextension panels 1012 in pre-folded (or unfolded) condition if desired (e.g., shown unfolded, with fold lines, onFIG. 79 ). Additionally,front ear portions 1144 can arrive at the chassis web in a pre-folded condition (e.g., shown unfolded, with fold lines, onFIG. 79 ), if a widerfront ear portion 1144 is desired. These configurations can also be combined with the chip removal technique previously discussed (or any other chip removal or die cutting or ear web formation technique), in which curved portions of either one or bothears leg portion FIGS. 80 and 81 ), the product configurations ofFIGS. 79-90 can be achieved. - Referring to

FIG. 87 , the embodiment ofFIG. 86 is shown with the additional product feature ofchips 1230 having been removed from both the front ear and back ear portions of the product, for instance using the severing and chip removal pattern ofFIG. 76 . Referring toFIG. 88 , a plan view of a product variation showing alternately rotated applied front ears, and alternately rotated back ears, using the previously described techniques, for instance the technique used to construct the product configuration shown inFIG. 28 is shown, with the exception that no extension panel is present in the embodiment shown inFIG. 88 . - Referring to
FIG. 89 , the embodiment ofFIG. 88 is shown, with the additional product feature ofleg portions - Referring to
FIG. 90 , the embodiment ofFIG. 89 is shown with the additional product feature ofchips 1230 having been removed from both the front ear and back ear portions of the product, for instance using the severing and chip removal pattern ofFIG. 76 . - The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
