Referring now in detail to the drawings in which like reference characters indicate like parts. the improved wrapping machine has been illustrated applied to the wrapping of magazines designated as M" which are fed to and travel through the machine ilatwise or in a horizontal plane and to which wrappers W are applied as continuous operation. The particular disposition of the magazines M as they travel flatwise through the machine is governed by the location of the several wrapping elements. In the illustrated embodiment the magazines are carried on their backs with their top edges in the lead and their back edges away from and front or open edges toward the front of the machine.

The improved wrapping machine is shown in its entirety in Figures l through 4. With r-eference to Figure l, the machine may be divided into two general parts, the first, extending in- Wardly from the left, inlet, infeed or leading end of the machine, the preliminary portion containing magazine infeed opening and inserting parts, and the second-extending from the preliminary portion to the right, outlet, discharge or trailing end of the machine, the main portion containing the wrapper-applying and sealing parts. In addition, the machine has also been divided with reference to Figure 2 into an inner or far side and an outer or near side. These terms will be employed throughout the description in denoting the positions of the various parts longitudinally and transversely of the machine.

The several wrapping elements of the improved machine are mounted on a conveyor table or platform I supported in an elevated position on a suitable base. At the infeed, inlet or left end of the machine is provided a hopper or feeding chute 2 in which the magazines are stacked for feeding or introduction into the machine. As shown in detail in Figures 5, 6 and 7, the hopper 2 is substantially U-shaped with its closed end at the right facing along the table formed as a lia-t rear plate or wall a", the bottom edge of which is spaced above the table. The sides of the hcpper may be formed as inverted U-shaped members, the upper ends of which slope inwardly to facilitate positioning of the magazines. A vertically disposed bar 5 may be adjustably attached to the outlet face of the plate 3 by which clearance between the surface of the table and the lower edge of the plate can be varied to accommodate magazines of different thickness and allow only one magazine at a time to be withdrawn from the hopper.

At the bottom of the hopper are spaced fixed runners 6 projecting above the surface of the table between which travels an inlet or infeed conveyor l, preferably formed as an endless chain or unidirectional conveyor having spaced upstanding fingers, pins or pushers 8 which project sufficiently to successively engage the bottom magazines of the stack and carry them in succession through the opening at the front of the hopper. As shown in Figures 1 and 2, the magazines are conveyed or caused to travel through the wrapping machine by a plurality of endless or unidirectional conveyors, all of which are preferably adapted to be driven through suitable chain or belt drives by a single electric motor or other source of supply Si, operated by a switch Sa. Of the several conveyors the feed chain 1 extends through the first or preliminary stage, phase or portion of the machine and is .carried at either end on sprockets i6, the inner of which is driven.

Attached to the upper face of the conveyor table or platform and extending longitudinally therealong through this first phase is a guide rail Il against which the .back edges of the magazines abut. Spaced along the machine from the hopper 2 is a slitter or magazine opener I2 which may be hingedly attached to the surface of the table and adjusted in height relative to the table through suitable means such as the adjusting screw I3. rThe opening or slitting blade or edge Ill of the opener is offset and projects into or lies in the path of travel of the magazines carried by the conveyor l. By adjusting its height through the adjusting screw I3, the blade may be caused to insert itself between the pages of each magazine and thus open the magazine at any desired level. To ensure both uniform opening and prevent dislodgement of the magazines during the opening operation a weighted presser foot I5 may be mounted on the table in advance of the opening blade Ill. As shown, the presser may be hingedly attached to the surface of the table and is adapted to engage and press against the front of each magazine.

At its outlet or trailing end the opener I2 overlies and engages the downslanting leading end of a guide rail I6 which is supported in elevated p0- sition above the table and over the path of travel 0f the magazines by brackets li'. After each magazine has been opened its upper portion is transferred from the opener to the elevated guide rail, the latter then maintaining the magazine in open position.

While it is possible to feed the magazines directly from initial opening to the wrapping stage, the condition of each magazine after the initial opening particularly lends itself to a heretofore tedious oeration. Accordingly, the travel of the magazines prior to the wrapping stage is preferably made sumcient to provide or encompass an inserter station i8 at which maps or other inserts I may be inserted into'the openings in the magazines, either manually or automatically. Beyond the inserter station there is preferably provided a second slitter, opener or opening blade or knife I9 which is adapted to insert itself into each magazine below the level at which the latter was opened by the opener I2, thus turning back additional pages of each magazine and pocketing the insert between these pages and those turned back in the initial opening, This opener is adjustable in height by shims or like means 19a and, as in the case of the first opener, overlies and is adapted to transfer the open or upper portion of the magazine to an elevated guide rail 2i).

Each magazine, containing its insert and open at the desired level, next enters the main or wrapping stage of the operation. As they enter this stage the magazines are transferred from the chain conveyor 1, rst to a pair of belt conveyors 2l and later to a second or main chain conveyor 22, both of which may be driven by the aforementioned motor 9, and the latter of which carries the magazines to the discharge end of the wrapping machine. As each magazine enters the wrapping stage of the machine it is met by a wrapper W which is fed into the path of the magazines by separate feeding and conveying means. While the wrappers may be fed into the machine in the same direction as that in which the magazines travel, an opposed feed is employed in the villustrated embodiment. This feed may comprise a feeding table or other suitable hopper or feeding device 23 of conventional type on which a plurality of wrappers may be stacked and by which the wrappers can be individually extracted from the stack and fed to an upwardly inclined or upslanting conveyor 24 underlying the work table I.

As shown in Figures l, 18 and 2l, the wrapper conveyor 24 travels along in a guidevvay which may be formed by upper guide rods 25 and lower guide rods 25a, respectively, round and channelshaped and suitably supported on the frame of the table and spaced to permit iiatwise travel of the wrappers. To ensure proper positioning of the wrappers their inner or far ends are guided by an L-shaped guide rail 26 and their outer or near ends are loosely supported on a raised inslantng guide rail 21, the latter causing the wrappers to tend to flow towards and maintain engagement with the guide rail 26 As in the case of the magazine feed conveyor 1, the wrapper conveyor is preferably formed of a pair of spaced chains 218 provided with upslanting pins or pushers 29, spaced to accommodate the individual wrappers. These chains are carried on sprockets 3|) at either end of the conveyor, the upper or left sprocket being mounted ona shaft 3| driven through drives by the motor 9.

As will hereinafter become apparent it is desirable to score each wrapper to facilitate the infolding of a vflap between the pages of the associated magazine at a later stage in the wrapping operation. For this purpose there is affixed to the underside of the wrapping table adjacent the upper or discharge end of the wrapperconveyor 24 a scoring device comprising a pair of multipointed scoring discs 32 and an opposed double grooved roller 33 positioned to engage each wrapper inwardly of its outer or near end and apply thereto two parallel rows of scorings or perforations 34 corresponding in spacing to the depth or thickness of the lower or unopened portions of the magazines.

On arriving at the upper or left end or terminus of the wrapper conveyor the Wrappers are transferred to an infeed conveyor 35. This conveyor comprises the aforementioned pair of relatively wide spaced belts 2| carried at either end on .drums or supporting drums and adapted to bear or press thereagainst are a plurality of relatively narrow spaced gripping belts 31 each engaging and driven through the wrapper conveyor driving shaft 3| and arranged in substantially V-disposition by a pair of pulleys 38 and 39. Of these pulleys the former is aixed to the top of the table and the latter is weighted to maintain the belts under tension and in tight engagement with the Wide conveyor belts. With this arrangement the leading edges of the wrappers are led from the wrapper conveyor 24 onto the gripping or pressure belts 31 and by the latter fed to theconveyor belts 2| and around the left drum 35, in process reversing the direction of travel of the wrappers to coincide with that of the magazines. As will be evident, the linear speeds of the wrapper conveyor 24, the conveyor belts 2| and the pressure belts 31, as Well as the magazine infeed or preliminary conveyor 0, must be synchronized to cause each wrapper, as it reaches the upper surface of the wrapping table to coincide with one of the magazines. This may be accomplished by the use of a single chain drive 40 running over sprocket gears of appropriate size affixed tov the drive shafts of the pulleys carrying the several members and driving this chain drive through suitable drives and reduction gearing by the motor 9.

As each of the wrappers is fed through a feeding slot 4| extending transversely across the table,

it progressively engages the underside or back of each magazine infed by the conveyor l) until the magazine rests on the wrapper with the back edge of the former substantially on the transverse center line of the latter and their leading edges substantially in line, thus dividing the exposed or uncovered portions of the wrapper into a rela-l tively wide inner or far flap 42 and a relatively- 6 narrow outer or near iiap 43, the latter being perforated as aforementioned. During this mating stage the inner or wide fiap is picked up by fold or deflector rods 44. These rods are of somewhat S-shape and cross over the path of travel of the magazines with the inner ends of the rods at table level and their outer ends supported thereabove, thus causing the inner flap to be progressively folded over the face or upper side ofthe magazine as the latter travels down the table.

As previously mentioned, the magazines reach the point of joinder with the wrappers in opened condition by virtue of the supporting rail 29 associated with the second slitter knife |9. While the magazine is still held open by an extension of this rail, the narrow outer or under flap 43 is brought into engagement with a tucker blade 45 of inverted L-shape and having an upper flange 46 of increasing width slanting downwardly and '1nwardly from the infeed or left end of the wrapping machine and projecting over the surface of the table in the path of travel of the magazines. So shaped, the tucker blade is enabled to first upfold and then infold or tuck the outer flap of the wrapper into the opening in the magazine over the lower or unopened portion of the latter, the resulting two folds in the flap being along the fold lines provided by the scorings 34. lower iiap is folded into the magazine the upper or unfolded portion of the magazine slides 01T of or is released by the supporting rail 20 and closes over the iiap. thus gripping it between the pages of the magazine.

Concurrently with the engagement of the outer flap 43 by the tucker blade 45 the inner or over flap 42 is engaged adjacent the back edge of the magazine by an overfolding blade 41 similar in shape and opposed in opening direction to the tucker blade 45 and attached to the table on the opposite or far side of the path of travel of the magazine.. This overfolding blade, which succeeds and assists the fold rods 44 in bringing the flap into engagement with the face of the maga-l zine, causes the inner flap to fold snugly over' the back edge of the magazine.

Spaced beyond the tranverse feeding slot 4| is the main conveyor 22 which is preferably formed of an endless chain similar to the magazine and wrapper feed conveyors and having somewhat similar upstanding pins or pushers 48. Assisted by the belt conveyors, this chain conveyor 'carries the magazines and their associated wrappers through the wrapping stage to the discharge end of the table. To prevent slippage of the magazines relative to their wrappers in the interval or space between the feed and main conveyors there are provided a pair of presser belts 49, each overlying one of the beltk driven 01T the drive shaft 3| of the wrapper con-` veyor 24 through a suitable belt drive.

In the illustrated embodiment the belt drive from the drive shaft 3| engages a pulley 54 on a shaft 55 to which is anixed the infeed'or leading pulley '56 of the inner rdriving belt 52. At its As the discharge or trailing end the inner belt runs over a pulley 51 affixed to a shaft 58 to which is also aiixed the trailing or discharge pulley 59 0f the other or outer driving belt 53, the leading or infeed end of which is carried by a fixed pulley 6D. Intermediate their leading and trailing pulleys, the belts are carried by a plurality of idler pulleys 6|, hingedly attached to longitudinal and transverse brackets, 62 and 63, respectively, mounted on and disposed above the surface of the table over the path of travel of the magazines. As shown in Figures 13 and 14, the longitudinal positions of the idler pulleys 6I attached to the longitudinal brackets 62 may be adjusted as desired while the heights of the pulleys 51 and 59 at the discharge ends of the belts are made adjustable by the adjusting screws 64. To maintain the magazines in proper position transversely of the table there are also provided an inner or far guide rail 65 and a partial outer or near guide rail 66, the former aligned with the inner guide rail Il associated with the feed conveyor 1 by which the back edges of the magazines are guided through the remainder of the wrapping operation.

Following the overfolding and tucking operations the outer of the conveyor belts 2| ends and the outer portion of the underside of each magazine is then supported directly on the table. The magazines then enter the sealing cycle or phase of the wrapping machine. At the start of this cycle the projecting sealing flap 5| is brought into engagement with a pasting or gluing device. This device consists of a pasting wheel 61 comprising a plurality of discs 68, the peripheries of which are formed in part by gear or other multi-surfaced segments 69. The pasting wheel is mounted on a shaft carried below the surface of the table and driven through suitable drives and gearing by the motor 9. Immediately above the wheel the table is slotted to enable the multisurfaced wheel B1 to extend therethrough and engage the underside of the sealing nap. Below its shaft the paster depends into an open-topped paste tank or container 1l. In this container the liquid paste or other sealing material is maintained at a substantially uniform level through a gravity feed connected to the bottom of the tank through a pipe or conduit 12 and having at its inner or far end a cup or inverted dome-shaped receptacle 13 for receiving a supply bottle 14 in inverted position.

To ensure adequate contact between the pastecarrying multi-faced segments 69 of the pasting discs 68 and the sealing flap 5I there is preferably provided a multi-bladed idler roller 15 which is hingedly attached to the table above the pasting wheel 66 and adapted by its weight to press the nap against the pastel', Since the several blades of the roller are positioned to interflt between the blades of the paster there is provided a stop in the form of a lock screw 16 positioned to engage the roller-supporting arm 11 and limit the downward movement of the roller when the machine is not in operation. Another element of the pastel is a wiper in the form of a multitoothed bracket 18 attached to the side of the tank above the paste level and positioned to remove or wipe excess paste from the pasting discs before they are brought into contact with the sealing ap.

It will be noted that the multi-faced pasting edges of the pasting discs 63 comprise only a seetor and that the remainders of the peripheries of the discs are of decreased diameter. The purpose of this divided periphery is to limit the application of the paste to that portion of the sealing flap intermediate its leading and trailing edges, this being accomplished by making the peripheries of the sectors of less length than the width of the wrappers. Consequently by synchronizing the revolutions of the pasting wheel 61 with the travel of the main conveyor 22 the leading and trailing edges of the pasting segments 69 will contact the ap 5l within its leading and trailing marginal edges, preventing excess paste from oozing or being forced out of the edges of the flap on sealing with consequent detriment to subsequent handling.

The slot in the wrapping table accommodating the pasting device extends therebeyond to provide an elongated stepped opening or slot 19 for sealing or accommodating the sealing ilap 5l during the sealing step of the wrapping operation. This slot is interrupted by a preferably one-piece underfolding device attached to the table through a bracket and comprising a downfolding blade 8l and an underfolding blade 82 arranged in succession. Of these blades the downfolding blade 8| is formed as a substantially V-shaped nger 83 disposed perpendicular to the table and having a nap-engaging underedge 84 downslanting toward the right from above the level of the flap to below the table. Thus, as it contacts the downfolding blade in the course of travel or progress of the associated magazine along the table, the sealing ap is downfolded against the front edge of the magazine. Beyond the downfolding blade 3l the under portion of f the ap 5l projecting below the magazine to the inner side of the table to which the adhesive was applied by the paster 61, is engaged by the underfolding blade "82. As shown, this blade has a twisted or turned face, starting as a at vertically disposed surface and ending as a flat horizontal surface level with the surface of the table. By virtue of its shape the underfolding blade is enabled to fold the projecting portion of the sealing flap under the magazine until it finally rests at against the back or underside of the wrapper.

As the front end of each magazine leaves the underfolding device its underside is engaged by a relatively wide belt conveyor 85 similar to the belt conveyors 2|, and its upper side is brought into contact with an over or presser belt 86 of relatively narrow width, As its name implies, the presser belt travels on a plurality of pulleys 81 which are hingedly attached to suitable brackets carried by the table and enabled to apply the sealing pressure requisite to4 effectively seal the sealing flap 5I to the back of the wrapper. This pressure is preferably applied continuously to the discharge end of the table.

To prevent wrinkling of the upper side of the wrapper during the pasting and underfolding operations there may be provided a smoothing plate 88 hinged at its leading end above the surface of the table and adapted to engage the wrapper adjacent the main conveyor 22 and hold it flat against the front of the magazine.

As the magazines sealed in their wrappers are discharged from the wrapping table they drop onto a discharge table 89 disposed normal to the wrapping table and carrying a discharge belt conveyor 90 by which the magazines are carried away from the wrapping table for further handling. As in the case of the several conveyors previously mentioned, the discharge conveyor may be driven through suitable drives by the motion of the machine.

tor 9 and synchronized in speed of the main conveyor 22. l

To facilitate understanding of the invention the heretofore described operation of the several parts of the wrapping machine has been shown graphically in Figures 2l and 22, the former being a perspective View showing a succession of magazines M at various steps in the wrapping portion of the machine. Figure 22 illustrates the various conditions or steps through which the magazines M pass as they travel or progress from the leading to the discharge end of the machine. Of the several views in this'gure, a shows the stack inwhicha plurality of magazines are introduced into the machine' through the hopper 2. In b the bottom magazine of the stack has been extracted from the hopper -by the feeding conveyor 1. In c the magazine has been opened by the initial opener blade l2. d shows a map or other matter I inserted in the opening in the magazine. In e the magazine has been opened at a lower point by the secondopening blade I9, pocketing the map between the upper pages. At f the opened magazine has entered the wrapping stage 'and rests on its wrapper W. In the next stage, g, the outer iiap 43 has been tucked into the magazine and the inner flap 42 is in pro'c'ess of being overfolded. In the next stage, h,v adhesive has been applied to the sealing flap 5 |`by` the' paster 6l. At i the sealing flap is 'in process vof being underfolded by the blades 8| and 82, and at y the sealing ap has been sealed against the back of the wrapper and the wrapping is completed.

In the illustrated embodiment of the wrapping machine numerous of the parts are shown as being adjustable, either automatically through the use of hinged or like mountings, such as those employed for the idler pulleys 6I carrying the driving belts 52 and 53, or manually through with the 4travel radjusting screws or like means, such as provided for the initial opener I2. With these adjustments it is possible to handle magazines and the like of varying thickness. It will also be evident that magazines varying in other dimensions can be handled readily by corresponding variations in the spacing or size of the several parts or elements of the machine without 'change in their character or function. While the illustrated embodiment is capable of wrapping magazines continuously at a relatively high output the arrangement of its parts is such that it is also adapted for use with a companion machine arranged in parallel if a higher output is desired. In such case by reversing the transverse positions of the o parts on the companion machine and employing either the same or separate power means to drive the machines, it is possible to operate a pair of machines either separately or together in a minimum of space without interfering with the view of the several operating stages or impairing the accessibility of the parts of either machine.

From the above detailed description it will be apparent that there has been provided an improved wrapping machine for continuously wrapping a succession of magazines or the like in which the magazines travel through the machine flatwise in a straight line throughout the wrapping operation, thereby simplifying the construc- While illustrated in its application to the wrapping of magazines, it will be understood that the machine is equally adapted to the wrapping of other fiat articles. It should be understood that the described and disclosed embodiment is merely exemplary of the invention and that all modications are intended to be included which do not depart either from' the spirit of the invention or the scope vof th appended claims.--` l Having described my invention, I claim:
