Description
- This present invention relates to an apparatus and a method for forming a block of folded material. Preferably, the apparatus and method will be used in the production of festooned packages that are commonly used in the hygienic industry, which commonly uses a web of non-woven fabric or airlaid material.
- International document WO 98/58864 shows a package of festooned web material that is cut into several stacks. As shown, the end of each stack is accessible so that it can be connected to the end portion of another stack. A strip portion is pulled from underneath the stack in order to provide a free end from the bottom of the stack. This operation generally had to be carried out manually, requiring someone to grip the end portion and arrange it in the preferred position. This requirement for manual handling presented a serious inconvenience, because the festooned packages are generally used in the hygienic industry. Cleanliness of materials used in this application is crucial and the elimination of manual operations is of utmost importance in order to preserve sterile and clean stacks of material. In addition, removing a strip from the bottom required flipping of the festooned block—a time consuming procedure.
- The present invention provides an apparatus and a method for separating the web from a block of folded material that can be used for hygienic products. The inventive apparatus and method is more effective in handling the web after the festooning of a block is completed.
- The apparatus comprises a holder for holding an end of the web from the bottom layer of the block, and a cutter for providing an end portion from the uppermost layer of the block so that manual handling of the web is no longer necessary during the entire process. The elimination of manual handling is particularly important for the production of materials that will be used in hygienic products, such as diapers and other sanitary products. Additionally, automatic handling of the web material reduces down time of the production line, thus increasing production efficiency. The apparatus also includes a holder integrated into the apparatus so that the end portion from the bottom layer can be laid on top of the block without requiring the entire block of material to be flipped.
- The holder may include a roller for winding and unwinding a portion of the web. The holder allows effective handling of the web as the height of the block increases in continued folding. This allows a continuous unwinding of the end portion and prevents loose portions from protruding or hanging from the block.
- The block may be formed on a receiving element which may be moved to a horizontally adjacent processing station. This movability decreases down time of the folder during the cutting operation. Alternatively, a conveyor may be used to move the block of folded material.
- In order to ensure effective and accurate cutting of the web, an accurate and precise cutter is required. The cutter includes a sledge and a cutting knife movable on the sledge. The knife can be rolled on the web, engaging the sledge in order to cut the web so that the material stress is minimized during the cutting of the web material. In order to obtain a more clean cut, a clamping bar may be used to fix a portion of the web onto the sledge.
- The holder may include a needle roller having protruding needles which may be inserted into the web, enabling the apparatus to handle the web without an additional clamp which would increase the risk of damaging the material. The protruding needles can be small enough in diameter to avoid any damage, since the web of non-woven or airlaid material is relatively light.
- In order to prevent damage to the needles during rotation of the roller, the sledge may have notches through which the needles may pass during its rotation. The notches guarantee the needles do not contact the sledge. Contact may fracture a needle, requiring one to discard an entire block of material, as broken needle parts wedged into the block may be exceedingly dangerous.
- A stripper may be positioned adjacent to the roller in order to ease the final release of the web from the roller.
- The invention also includes a method for forming a block of material. According to the inventive method, the web is folded on a receiving element until the folded block reaches a desired height. Thereupon, the uppermost web layer is fed into a cutter and is then cut, whereby the end of the bottom layer is laid at least partly on top of the block.
- An end portion from the bottom layer of a block may be withheld on a holder before starting to form the block, so that during the block formation, the holder can retain a sufficient part of the web to allow arrangement of the end portion at the side of the block, since the height of the block increases as the block is formed.
- The block is moved in the horizontal direction so that the holding and releasing of the end portion results in laying down the end portion on top of the block. This step ensures that the end portion from the bottom of the block is laid on top of the block.
- Preferably, the uppermost web layer is cut, and its end portion falls down on one side of the block. If the web is perforated to enable different lines of the web to be pulled from the festooned block, the different lines may be connected to one another. Such a splicing operation requires the connecting portions to have a preselected length, because removing the end portions from the stack could result in damage to the web.
- Other objects, advantages and novel features of the present inventive method and apparatus will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.
- FIG. 1 is a side view of the inventive apparatus according to the principles of the invention.
- FIG. 2 is a side view showing a beginning of the method for providing loose end connecting portions on top of a block of folded material.
- FIGS.3-9 show various steps of the method for forming a block with loose ends arranged partly on top of the block.
- FIG. 10 is a side view of the apparatus according to the principles of the invention.
- FIG. 11 is a plan view showing the sledge and needle roller of the inventive apparatus.

The bottom layer of theblock 5 has anend portion 7 which is retained by atail holding roller 8. Asledge 9 is positioned near the upper left side ofblock 5. A rail system guides thesledge 9, which is moved in a horizontal direction by an electric drive system (not shown). - A
needle roller 10 is positioned on the upper right side of the block. Aclamping bar 11 is positioned below theneedle roller 10. Theclamping bar 11 is movable in a horizontal direction. Before beginning the cutting operation, the finishedblock 12 is removed from the position found in FIG. 1. - FIG. 2 shows the starting position for separating the web from a
block 5 of folded material. Initially, theblock 5 is moved horizontally from thereceiving element 6, so that the block passes under thetail holding roller 8. - As shown in FIG. 3, the end portion is laid down on top of the block. The horizontal movement of the
block 5 may be accomplished by either moving thereceiving element 6, or by using any known conveyor means. - As seen in FIG. 4, the
block 5 is moved completely beyond thetail holding roller 8, so that theend portion 7 from the bottom layer of theblock 5 is arranged on top of the block. - As seen in FIG. 5, the
sledge 9 begins to move under thefolding cylinders bar 11. Meanwhile, thetail holding roller 8 is moved in the same direction as thesledge 9. - As seen in FIG. 6, the
sledge 9 moves under theneedle roller 10, and the clampingbar 11 clamps a portion of theweb 4 to thissledge 9 in order to cut theweb 4. In this position, the needle roller rotates, thereby inserting some of the needles into theweb 4. This prevents theweb 4 from falling after it has been cut. Then a cutter is moved onto thesledge 9, separating theweb 4. Thecutter 13 may include a rolling knife in order to reduce a friction between thecutter 13 and thesledge 9. At the cutting area, the sledge is made of hardened steel in order to reduce wear. - As shown in FIG. 7, the cutting of the
web 4 leaves anend portion 14. Bothportions block 5, so that they can be easily detected and gripped for further processing of the folded web. The other part of theweb 4 forms anotherend portion 7′, which is fixed to theneedle roller 10. Thereafter, thesledge 9 returns from its position under theneedle roller 10, to its original position, which is shown in FIG. 2. - As shown in FIG. 8, the
needle roller 10 rotates about its axis in order to provide anend portion 7′ of sufficient length before beginning to fold another block. This winding process is followed by thefolding cylinders web 4. An addition, thetail holding roller 8 is moved to the left side under theneedle roller 10. - FIG. 9 shows the starting position for forming a new block of folded material. The
new end portion 7′ from the bottom of the new block is partly unwound from theneedle roller 10, and hangs between theneedle roller 10 and thetail holding roller 8. The rotation of thefolding cylinders element 6 moves downward. This action pulls a part of theend portion 7′ on the side of the new block. After forming the new block, the cycle repeats and the parts move to their position as shown in FIG. 2. - FIG. 10 shows the apparatus according to the principles of the invention. Note that the apparatus is shown in a position similar to the position depicted in FIG. 7. The
cutter 13 has acutting edge 21 which engages the hardened surface of thesledge 9. Theweb 4 is clamped between thesledge 9 and the clampingbar 11. - The
needle roller 10 hasrecesses 22 withneedle holders 16 in which needles 15 are mounted. Theneedles 15 are angled with respect to the radio direction.Recesses 22 may be integrated into thecylinder 17 of theneedle roller 10 in order to locate theneedle holders 16. As theroller 10 rotates, someneedles 15 are inserted into the web. This ensures a holding of theweb 4 onto theneedle roller 10. - As shown in FIG. 11, the
sledge 9, shown on the bottom side, may includenotches 18 which are slightly wider than the diameter of theneedles 15. As theneedle roller 10 rotates, theneedles 15 pass through thenotches 18, so that theneedles 15 do not contact thesledge 9. As theweb 4 is held between thesledge 9 and theneedle roller 10, the needles are inserted into theweb 10. As evident in FIG. 11, the sledge may be driven bybelts - A stripper30 may be arranged at the
needle roller 10 in order to ensure that theweb 4 is released from theneedle roller 10 when it unwinds.
