Description

A PACKAGE OF A STRIP OF MATERIAL AND A METHOD FOR SUPPLYING A STRIP OF MATERIAL}

The present invention relates to a package of strip material and a method of forming a package of strip material.

In many cases, the continuous strip material may be wound on a single spring-shaped roll known as a pad or pancake, or it may be a wrapped package in which the strip crosses back and forth in the spring shape. These two configurations are limited in the length of the material and require fly attaching for continuous operation. In addition, the package structure may damage the band due to the change of tension through the diameter of the package. Conventionally, a continuous band-shaped package has a long length of festooning (flowers, leaves, ribbons, etc.). It was formed using a technique known as draping, where the bands were folded back and forth so that a series of bands were placed back and forth, with each band folded about the next band around the line across the band. Pestuning's technology has been available for many years and has been used in many different materials for packaging, but has been used in particular for textile materials such as wovens, nonwovens and the like. In this technique, the strip is typically guided into a container, such as a cardboard box, with a first reciprocating motion allowing portions of the strip to lie across and retracting back and forth, and a second reciprocating motion The section was crossed across the container. Typically the container comprises a rigid rectangular container that is partly cardboard with at least a bottom and four upright sides.

The purpose of the festooning method is to package the strips for feeding them to a machine using the strips. Some users prefer festoon packages over cold packages of this type of material. The festoon package can simply be positioned adjacent to the machine without the need for any driven release stand. Additionally, since the leading and trailing ends of the package are available at the top of the package, a series of packages act as one extended source from front to back. In addition, the material is simply broken down into the package, which results in the tension control of the large package due to the inertia of the package and thus is pulled out of the package as compared to the larger strapping packages that require a driven release stand. There are also fewer problems with the control of tension in the material. Thus, the festoon package does not need to be used for a complex unwinding stand that occupies more space than is available and involves significant costs.

The festoon package is in the form of a rigid container or box to properly store and contain the material, and the material is stored therein at the time of transport to maintain the material against compression and deformation as the baggage is conveyed with the surrounding package. The cardboard container thus provides support for other similar laminated containers and prevents excessive compaction of the package from occurring at the bottom of the lamination upon conveyance of the cargo. Cardboard containers and packages used in conventional configurations have a number of problems.

First, the containers must be recycled or disposed of in need of shipping cardboard containers in the direction of return from the end user to the supplier, both of which are costly.

Secondly, since the cardboard container simply holds the material without significant compression, there is a waste of space in the container as the air is packaged with the material. In addition, the conventional package structure does not minimize the amount of space formed in the structure. Therefore, the transportation cost of the material is significantly increased by the large capacity of the material, which provides a density significantly below the optimum for most efficient transportation.

Third, the presence of the essential box during the construction is limited in its proper control as the strip is placed because the sides of the box limit the movement and position of the guide member controlling the strip. to be.

Fourth, as the strip is placed, the side of the box parallel to the strip does not closely regulate the side of the package structure, and there is a risk that the strip may fall between the side of the box and the edge of the package.

In addition, conventional packaging techniques in which each band split from the fabric of the feedstock is individually packaged in separate festoon stations are very slow and require a large floor area for a large number of stations. The large area covered by the station also increases the distance the band travels from the cutting station to the festoon station, along with potential band tension problems and risks for the band. US Patent No. 5087140, issued February, 1992.

Thus, while the significant requirements for this type of package remain, the technology currently available is unsatisfactory for the reasons mentioned above.

It is therefore an object of the present invention to provide an improved package structure and packaging method for strip-shaped materials in which the stability of the package can be improved. [0007] The continuous rubber folded back and forth in such a way that the fan is folded to form a stack of strips. It is also known that the strip is drawn out from one end of the laminate by feeding the strip continuously. Accordingly, fan-folding bands that are simultaneously folded to form side-by-side stacks of bands are disclosed in US Pat. No. 3,372,393 to Shore in April 1973. The bands are connected to the next band by a series of connecting tabs which must be broken before these bands can be used. These rubber bands are used in an extrusion machine and individually supplied by the operator to the interior of the machine. In non-related fields, individual stacks of strips, such as tickets, are folded in a fan shape, each stack being contained in a separate container or cassette. It is known to package in a configuration. One example of such a configuration is EP 0 383 501 A (Almex Control System Limited). The strips have a tail that extends from the bottom of the cassette to the open top and hangs at one end to be connected to the strip of another similar cassette. However, individual cassettes must be prepared essentially as individual sources of strips. These cassettes are provided in a vehicle parking system, and in most cases one or two additional cassettes must be prepared to be supplied to users. Another example of a prior art example in this field was given to Yamamoto in January 1993. US Pat. No. 5,177,934, in which a strip of single toilet paper is folded into a stack and compressed into a vacuum pack instead of being rounded.

According to one embodiment of the present invention, each folded portion of the stack comprises a plurality of laminates each comprising a strip folded back and forth so that the side edges of the strip portion are folded about the next portion around a line across the strip and the side edges of the strip portion align. Is configured; The bands are continuous through each stack from one end of the stack to the bottom of the band at the opposite end of the stack, with the stacks next adjacent stack without interfering with the rigid container wall. In the package of strip | belt-shaped material arrange | positioned side by side together as a common package with the side wall of the strip | belt part of each laminated body in the vicinity of

The ends may be connected to the other end junctions so that a continuous strip is produced from the connected laminates, or the ends are already connected to the other end junctions of the other laminate to provide a continuous die formed by the laminated stack, one of which is connected. A package of strip material is provided wherein the top and bottom ends of the strips of each laminate are arranged in the package to provide end connections.

According to a second embodiment of the present invention, there is provided a method, comprising: side-by-side supplying a strip-shaped material arranged as a plurality of strips; each folded portion of the laminate is folded and folded about a next portion around a line across the strip; Forming a stack comprising a strip that is folded back and forth to align the side edges of the strip portion; the strip is continuous through each stack from the top end of the stack to the bottom end of the stack; The strip material comprising the stacks arranged side by side in parallel to form a material such that the side edges of the strip portions of each stack are adjacent to the side edges of the next adjacent stack without disturbing the rigid container walls. A method of forming a package of the present invention; Provided at the top and bottom end of the strip of each laminate, the end connecting portion in the package Each of the goads may end-connect the end junctions to the other end junctions to make a continuous strip from the joined stack; or one end junction of the stack to produce a continuous strip formed by the linked stacks. A method of forming a package of strip material is provided, characterized in that it is connected to each end connection of another laminate. Embodiments of the present invention are described with reference to the accompanying drawings:

11 is an equivalent view of a package according to the present invention showing a state after the belt is partially unwound and decompressed for use, and a state in which the bag is omitted for convenience of illustration.

A first embodiment of a package according to the invention is shown in FIGS. 1 to 5, in which the package comprises a substantially rectangular body 10 formed of a flexible strip or sheet 11 to be packaged. This material is a fiber formed from a woven or nonwoven material, although not essential to the package structure. As long as the material is capable of forming the required wrinkles at the ends of each folded strip, many materials of varying thickness can be packaged using the techniques described above. The band has a width that is greater than the thickness, thereby defining two approximately flat faces and two side edges. Such bands are preferably constant in width but not necessarily.

As shown in FIG. 2, the completed package for use in the end of the machine is shown, with the strap having a front end 12 and a rear end 13 of the package, the other part being continuous through the package. As shown in FIG. 2, the package, when fitted in its normal position for conveyance or use, includes a top 14, a bottom 15, two sides 16 and 17, two ends 18 and Has 19.

The package is formed from a stack of multiple bands. In the illustrated embodiment, a stack of four bands, shown at 20, 21, 22 and 23, respectively, is shown. The stacks are parallel and side by side and have no media. These stacks are parallel to the sides 16, 17. The package has end stacks 20 and 23 and a plurality of intermediate stacks (two in this embodiment).

The term "laminate" is not intended here to require that the laminate is vertical or that the position of the laminate is specific. Laminates, on the other hand, are usually formed by placing the strips on top of the front strips to form an upright stack, which is not essential in construction.

The size of the package can vary as needed, so the number of stacks, the length of each stack and the height of each stack can also vary within the limits of width.

Each strip stack consists of a plurality of strip portions placed on one top. Thus, as shown in FIG. 1, the band portions are folded back and forth to form an accordionally folded sheet at each end fold lines 25 and 26. Since the parts of each band are placed directly on top of the preceding part, the bands have a constant width. As shown in FIG. 3, the side edges 27 and 28 of the portion of the strip lie on a common vertical surface 27A. The side edges 27 of the strip stack are thus aligned, and the side edges 28 of the strip stack are also aligned.

The package is thus formed by placing the strips from the bottom 29 to the top 30 on top of the next strip, forming a stack. The package is thus formed of a plurality of stacks, each stack having the same length as the other stacks in the direction of the bands on which it is formed. The laminate is also formed with a common height and is therefore equal to the height of the package.

As shown in FIGS. 4 and 5, but for the sake of illustration, as omitted in FIG. 2, the package is preferably wrapped in a flexible package material 40, an impermeable plastic that is heat sealable to enclose the entirety of the package. The package material preferably has a base portion 41 and a side portion 42 and an upper portion 43 which is heat sealed and enclosed around the package as indicated by reference numeral 43A in FIG. 5. The package is compressed from the ends 14 and 15 to significantly reduce the height of the package, which compression draws or ejects air from the package. Since the sealed bag is used in a vacuum package system to keep air outside the bag, the air pressure outside the bag keeps the package compressed in the height direction and keeps the stacks in contact with each other. The amount of compression and the amount of reduction in the height direction can be considered to minimize the amount of the package without disturbing the height of the product required when being pulled out of the package. Packages and sealed bags defined only by a laminate define a rigid structure that stands free. In this way, the package structure avoids the need for a box with a rigid side or similar container, the package structure compresses the laminate to reduce the height of the laminate, and then to the sides of the next adjacent laminate. It becomes stable by the pressure of each laminated body with respect to.

The flexible package material does not necessarily need to be a bag, but can also be a simple package. The use of vacuum and compression laminates to maintain packing is preferred, but not necessary.

Compression of the package is possible only in the direction D perpendicular to the surface of the strip. This acts to compress the thickness of the band portion, so that the length of each laminate in the D direction is reduced by its compression. Compression along the band or at right angles to the stack is not possible because the band twists. Therefore, mechanically compressing the package in the D direction by the sandwiching substrates D1 and D2 reduces the size of the package in that direction so that air is extracted out of the flexible package material 40 and the package material is It sticks to the package to keep it compressed and pressurize the laminate to stay tight.

In the state of the package material shown in Fig. 4, the base material 41 of the package material or bag 40 is formed and sized to be slightly larger than the uncompressed state of the package structure itself. In this way the package structure can be easily inserted into the plastic package material or the bag and held in place by the package material. Upon transport and storage, the package structure is compressed and in a vacuum state. In this state, the side portions 42 of the package material are compressed in the D direction to form the wrinkles 39. However, when the vacuum is released, the package is inflated from the compressed state to a normal loose state, the bag expands to its initial size and the wrinkles 44 are stretched out.

The package, as a laminate, may exhibit a direction as shown in FIG. 2, which is formed by laying the strip horizontally to erect the laminate vertically. In this orientation, the top of the bag is at the top of the package. In the directional relationship shown in FIGS. 4 and 5, the package rotates 90 degrees, so that one end 18 is at the top. Although not required, it can be so and can help to partition as described below. In this orientation, the top of the bag is positioned at the end of the package. The package can also be rotated so that one side is on top, as shown in FIG. In all of these orientations, the package becomes stable when it is wrapped so that it can be handled stacked on top of another package using conventional transport and handling systems.

However, it is preferred that at least the package is left unfolded and held vertically to feed the strip to the end-use machine as shown in FIGS. 9 and 10. In this directional relationship, the stacks 20, 21, 22, and 23 are all upright and side by side, so that the individually folded bands are separated from the horizontal upper band 30 of each stack. The horizontal bottom band 29 of each laminate remains horizontal.

The initial structure of the package as shown in FIG. 1 includes a laminate in which bands separated from the following bands are formed side by side. This is accomplished in one structure by dividing the fabric into a number of side by side bands and folding these bands simultaneously side by side using a carriage having a pair of nip rollers. The nip rollers reciprocate on the carriage at right angles to their length, so that the nip moves back and forth between the ends 18 and 19 to be placed in the measured band length and at the fold lines 25, 26. Fold the straps.

As shown in FIG. 1, the upper end strips 30 of each stack 20 are generally laid across the top of the stack, with free ends towards the ends 18 draped downward from the top 14. Will have (44). The top end of the stack 20 can be pulled out to form the front end 12.

The bottom strip 29 includes a tail 45 formed prior to the formation of the stack as part of a strip that is removed from the bottom of the stack and suspended to the side 18 of the package.

In some manner of material or in some processes, the tail 45 may or may not be connected, as shown in FIG. 1, and may simply be freely placed on top of the package material to be connected after transport and storage have been completed. It can be seen that the package structure is stable and thus usable so that it can be loosely connected when transferred to the machine to be supplied. Thus, the connection may be made when the package is waiting to be released after conveyance or when the first stack 20 is released. By holding the tails 45 in position from the top of the package upwards along the sides of the package, these tails are made available so that the package material as described above can be held in place and the package material Alternatively, the upper portion of the bag may be opened or removed to use from the upper end and the upper portion of the tail 45.

As shown, the tails 45 are arranged at the end 18 of the package. It is theoretically possible but practical to have the tails arranged alternately at the opposite ends 18 and 19, for example the tails 45 of the stacks 21 and 23 arranged at the ends 19. It is not preferable.

As shown in FIG. 2, preferably, prior to conveyance, the tails 45 are joined to the upper portion 44 by means of a join 46. Since the attaching is possible without the need for high speed operation, an effective attaching system including stitching, taping and heat sealing can be used which takes more time than is normally used in current production lines. have. The joins are shown as superimposed, but in practice they may be faced to eliminate the superimposition.

The joining is carried out so that the surface A of each strip is attached to the surface A of the strip of the next adjacent laminate, and similarly the surface B is connected as well. In some cases, this is necessary because the bands have different surface properties. In some cases, this may not be necessary for the treatment of the strip, but in general it is desirable that the strip is fed so that no twist occurs in a consistent manner.

In order to keep the strap free from being twisted, it is necessary to mold the tail 45 in the direction of encountering the twist that occurs when the release conveyance is made from the stack 20 to the stack 21. Careful strip analysis and unwinding processes show that one twist occurs when transferring from one stack to the next. Therefore, it is necessary to count the number of twists by one twist 47 at the tail before the stitching 46 is performed.

Preferably, this twist is applied to the first fold line 48 at the first strip portion 50 and the second fold line 49 at the strip portion 51. The first fold line 48 and the strip 50 are aligned with the stack 20 and the fold line 48 is horizontally aligned at an angle of 45 °. This forms a horizontal portion 52 of the band extending from the fold line 48 to the fold line 49 and is perpendicular to the normal vertical direction of the tail 45 and the bands 50 and 51. And substantially horizontal. The first fold line 48 causes the horizontal portion 52 to lie outside the vertical portion 50 of the tail 45. The second fold line 49 is the vertical portion of the tail 45 51 is arrange | positioned so that it may be inside the horizontal part 52. FIG. This configuration provides a configuration that allows for a single twist while minimizing the length of the horizontal portion 52 and limits the available drooping portion of the tail 45 which can be aesthetically drawn and erroneously twisted.

The vertical part 51 of the tail 45 extends to the place 46 where the stack 21 is connected vertically, from which the strip 44 extends to the side of the stack 21 and the stack Extends to the top of 21;

The horizontal portion 52 is preferably arranged at or near the bottom of the stack 20, so that almost all the tails 45 are supported by the stack 21 as the stack 20 is picked up. do. Thus, when the tail 45 is harvested and before being conveyed through the tail 45 from the bottom 29 to the top 44 of the stack 21, there is little possibility of entanglement with the band from the stack 20. none.

3, 4 and 5 show the same package as shown in FIG. It is shown in FIG. 3 in a partially continued state, so that part of the tail 45 is connected to the relevant portion 44 of the next stack. In FIG. 3, the same positional relationship as that shown in FIG. 2 is shown. The compression plates D1 and D2 thus operate vertically. In Figures 4 and 5, the same package rotates in the fitted plates D1 and D2, so that the plates are vertical and the end 18 moves upwards. This facilitates stitching and twisting by placing the tails 44 and 45 in a horizontal orientation since the tails are held in place by the horizontal ends 18.

In Fig. 4, the package is in a state before compression but the bag 40 is in an open, twisted state. In FIG. 5 the package is compressed and held by the bag 40. In this state, the height of the package between the ends 14 and 15 is reduced as shown by the compressed height at the normal height, which is the ratio of the usual height that varies with the degree of compression of the material.

This reduction in height leaves the free portion 54 of the connections 44 and 45 to be accommodated in the compression portion. This is achieved by carefully folding the connections 44, 45 at the first transverse line 53 and the second transverse line 53A as shown in Fig. 5, both of which are perpendicular to the length and free portions. Half of the length of 54 is occupied.

Compression is performed mechanically in the D direction by fitting plates D1 and D2 until there is a desired decrease in the height of the package. During this compression, the connections 44, 45 are loosened and excess length 54 is formed. Since the folding operation is performed carefully by hand, the folded portions as shown in FIG. 2 are placed on each stack together with the respective band portions 44. When compression is complete and a folding operation is performed, the bag is sealed and sealed using a commonly available vacuum sealing system that seals the top edge of the bag and draws out the bag's internal air. In addition, evacuation can be used to assist mechanical compression when the bag is not sealed, so that the bag can be opened to perform careful folding operations and sealed after the folding operation is complete. However, wrinkles of the tail 45 should be avoided during vacuum extraction.

The spacer member 58 is located between the ends 44 including the connecting portions 44 and 45 and the fold line 25. Even when heavily compressed, it can be seen that the fold lines form a non-uniform surface with a series of transverse grooves and ribs defined by the actual fold lines. It is important that the connections 44, 45 are made flat and free of wrinkles, and if these connections are vacuum compressed from the bag to the end 18 (i.e. air pressure from outside the bag), wrinkles may be formed.

The spacer member 58 is thus a closed cell foam, for example, a relatively hard and flat material which defines a flat outer surface 60 which is attached to the compressible filler material 61 on the underside. It comprises a rigid sheet 59 formed of a. The rigid sheet may be formed of cardboard or similar material having sufficient rigidity to remain substantially flat, thus defining a flat face 60 facing the connection. Since the compressible material or foam is arranged to fill the grooves between the fold lines and compress at the fold lines, the rigid sheet remains flat and does not compress into the grooves.

The spacer member may be used even in the above-described state in which the package is conveyed after compression and wrapping in the configuration shown in FIG. 1 used to prevent wrinkles of the tail portions 44 and 45.

Fig. 6 shows a selection example for the connecting portion which does not need to be folded at the time of compression. The connecting portion extending from the tail portion 45 to the tail portion 44 is twisted as described above to form the torsion portion 47, and are joined together to form the joining portion 46. However, in this configuration, the joining is performed such that the connection is taut across the end 18 of the package without the fold corresponding to the fold 54 of FIG. 2. Thus, in FIG. 6, the package represents a compressed state where the bag is sealed and under vacuum.

The package is in a state where the bottom end 15 is leaning against the horizontal support and the upper end 14 is looking upward. In this position, the bag can be inflated to release the vacuum and return the package to its normal state. In this expansion, the connection has an insufficient length to reach its normal height, so that the excess length necessary to form the extended connection is pulled from the upper band portion 30 as indicated by arrows 30A and 30B. Obtained.

Slip sheet 30C located between the upper two bands and the third belt portion 30D in order to ensure that the upper end band portion 30 slides freely across the upper end 14. ) Is provided. Thus, the fold line 26 at the end 19 of the package is pulled away in the direction of arrow 30B and away from the band portion 30D and the next adjacent fold line without tending to be pulled with the next band portion 30D. Can be pulled. The slip sheet may be formed of any frictionless low friction plastic sheet or similar material. The slip sheet covers the entire area between the ends and the sides, thus separating the two bands from the rest of the package.

In Fig. 7, an alternative configuration for performing torsion, stitching and folding operations at the connecting portions 44 and 45 is shown. In this configuration, the package remains in its original position with the top 14 at the top. In this positional relationship, before compression, the connecting portions defined by the tails 44 and 45 are twisted as described above to form the torsion portion 62, and the seam 63 is formed as described above. Although they are joined to form, the difference is that the torsion and the seam are located on the upper end 14. These are done on the horizontal top surface of the package, so that they can be done manually without difficulty due to support from the top end 14. The joining is performed such that the height of the tail 45 from the bottom of the package along the end of each stack is equal to the height of the package in the uncompressed state.

In a package structure in a bag having an open top facing the package end 18, compression is performed as shown in FIG. 3 using fitting plates D1 and D2. In order to prevent the side of the package from protruding to the side by compression, a pair of side plates 64 and 65 support the side of the package during the compression operation. The bag is, of course, located inside the plates 64 and 65 at the top of the fitting plate D2 and at the bottom of the fitting plate D1.

When the package is compressed, the length of the tail becomes longer than the compressed height of the package, thus forming a carefully folded excess as shown in FIG. In situations where the compressed height is less than half the normal height, multiple folding configurations can be used to define the fold 66 comprising fold lines 67, 68, 69 and 70. . The spacer plate 68 is located between the end 18 of the package and the tail 45 and the fold 66.

8 shows another alternative technique for accommodating the seams, torsions and folds required at the connection. In FIG. 8, the ear paste is located at the top of the upper end 14 similarly to the configuration in FIG. However, the torsion and folds are located on the end 18 of the package and are coupled to one element. Thus, the second fold line 73 and the first upper fold line 72 in the direction of automatically twisting the strip around its length to make a single twist 74 required at the same position as the fold. ) Thus, in doing so, the fold corresponds to the extension of the fold in FIG. 2. This folded portion is clean in appearance and reduces the crease of the band, because the fold lines 72) and 73 are separated by the length of the fold 74 and are located closely across the length of the band. Because.

9 and 10 show a technique for unfolding a package formed as shown in FIGS. 2 to 8 and described above. Although a particularly illustrated package is shown in FIG. 8, the position of the torsion and the gluing portion has little or no influence on the unfolding operation, and therefore the packages shown in FIGS. 2 to 7 act the same.

Thus, as shown in FIG. 9, when the package is released from compression, the connection loosely stretches with the torsion portion 74 at some position along the longitudinal direction, which leads to the unwinding operation from one stack to the next. Make it effective. The bag 40 is cut away and the top 43 and sides 42 are removed leaving only the bottom 41 and a portion of the side spanning over the surface 82. Spacer 58 is removed.

The package is placed on the release stand 80 for the unwinding action. This provides a generally horizontal main support surface 81 on which the laminates 20 to 23 stand up in a way of unwinding from top to bottom.

Additionally, stand 80 includes side support surface 82 perpendicular to face 81. The stand is then inclined at an angle of about 10 to 20 degrees sufficient to tilt the package to one side, so that the stack 23 is leaning against the surface 82 and each of the remaining stacks is leaning against the next adjacent stack. Lose.

The angle is sufficient to prevent the laminate from collapsing or tightening with respect to the other laminate in a direction away from the surface 82.

It can be seen that the tendency of the package to slightly expand and pull on the first stack 20 is that the first stack 20 tends to fall while the other stacks remain stable. This angle is thus selected to prevent the possibility of the first stack falling down and to prevent the possibility that each subsequent stack will fall when the first stack and the other stack are unwrapped. The first tooth stack 20 is thus able to be unrolled from the top down, followed by each stack in turn. This configuration has the advantage that it does not require another support for the package side, and keeps it in place when the package is unwound. In addition, when releasing another laminating agent from one laminate, it becomes possible without frictional contact with a band of another support or package material capable of tearing the weak material.

The bands can be used for cutting bands into a continuous series of sheet materials having a predetermined length. While placing the stack in a package system as described above, an indicator (not shown) for placing a mechanically readable marking 90 on the strip in line with the fold line is located near the package system. The markings include inkjet markings, possibly in the form of dots or squares, and can be read by the naked eye or a cutting machine or in some cases directly by a machine. The marking may or may not be located directly on the fold line, depending on the position of the machine reader 91 relative to the fold edge 92 or the cutting edge 92 arranged to cut near the fold line. In the illustrated embodiment, the marking is located at the beginning of the folding line or the intended cutting line. The marking may extend across only a short portion of the width of the strip. When the marks are fitted to each of the fold lines, each mark may be slightly out of the associated fold line by the same spacing. In a configuration where only the fold line is indicated by the inkjet mark, there will be only one mark on each band. In order to keep the cutting line on the fold line, the number of sheet materials on each band portion needs to be exactly the same as the number of parts to be cut entirely. In many cases, the relative lengths of the sheet material and the strips are such that the number of portions to be totally cut is one or more. Thus, each intended cutting line may be displayed, and only the folding line may be displayed. The cut lines thus allow the fold lines to be placed close enough to the ends of the sheet material to prevent the fold line from degrading the performance of the sheet material.

In FIG. 11, a package formed from the same stack as described above is shown positioned horizontally on top of another stack so that the stacks can be unwinded from the top. It is possible to use the same jointing, twisting, dismantling structure as described above. However, simpler attaching techniques are available if the package is positioned in this manner. Thus, when wrapped, compressed and sealed, the package structure is positioned so that the laminates 20 to 23 are horizontal. In this positional relationship, the vertical load from one package to the other allows the conveyance through the package structure to be palletized downward without distorting or damaging the bands. This is due to the fact that when the band is compressed into a stack, it is relatively hard across its width, and the bands together form a substantially rigid structure.

As shown in FIG. 11, the upper stack 20 is partially from the leading end portion 12 towards the trailing end portion 94 of the stack at the end 14 of the package. Unfolds. The next stack 21 has its front end 95 at the same end 14 as the attracted end 94, and the stack 21 by means of a connecting portion 96 comprising an seam 97. Is connected to the front end 95 of the head. The connecting portion 96 lies on the same plane as the end 14 and normally extends diagonally between the laminates 20 and 21.

In a symmetrical manner, the attracting end (not shown) of the stack 21 is connected to the front end by means of a connecting portion (not shown) including an seam. Both the trailing end of the stack 21 and the connecting and front ends of the stack 22 are arranged at the end 15 of the package in the same plane as the tip 15.

Furthermore, at the end 14 another connection 98 and an ear paste 99 interconnect the attracting end 100 of the stack 22 and the front end 101 of the stack 23.

Connections 96, 98 and further connections for additional laminates are arranged at the ends 14. The connections for the laminates which alternately float one by one are arranged at the opposite ends 15. The connections are in the same plane as the ends of the strip and thus lie flat on the sides of the package when packaged and wrapped as described above.

The positional relationship of the packages used to unfold the packages is as shown in FIG. The bag is placed in place to properly hold the end strips and connections, but the top 43 is opened by cutting or removing a small opening, and the front end 12 of the strip is found and pulled out of the opening. By placing the packages in this positional relationship, each stack can be unfolded in sequence without the risk that the stack collapses because each stack is laterally supported by the lower stack.

It can be seen that the illustrated stitching technique ensures that when the bands are unfolded as shown in FIG. 11, no twisting is applied as the unfolding action is moved from one stack to the other stack. However, in order to ensure that the side A of the strip of the laminate 20 is in contact with the side A of the laminate 21 (also, the side Bs are connected), it is necessary to turn the band of the laminate 21 upside down. have. Symmetrically, the laminate 22 has the same directional relationship as the laminate 20, and the laminate 23 is inverted like the laminate 21. This flip is obtained by physically lifting the intermediate stack and rotating it 180 ° about an axis perpendicular to the stack. The same effect can be obtained by twisting the strip 180 degrees when the strip is fed into the folding system for simultaneously folding side by side as described above. This torsion has the effect of facing side B outward of the fold line at the ends 18 of the stacks 20 and 22.

An optional configuration of folding and compression techniques as described above can be used for a single strip laminate. Such bands can be relatively wide, for example folded fabrics or carpets folded back and forth, packaged in bags and compressed and held as vacuum bags by external air pressure.

This compression reduces the height of the laminate to some extent, making the structure rigid and free standing, thus protecting the strip and allowing for easy handling.

In order to prevent unintentional expansion of the package at any time during conveyance, storage or handling, for example by piercing the bag or releasing the vacuum, the bag is a shrink wrap material that holds the package in a compressed state. It can be wrapped in the back.

In another embodiment (not shown), the package can be formed by constructing each stack in turn from a single end of the strip, so that the strips are continuous from each stack to the next stack without the need for seaming. . This technique has the disadvantage that the construction of the laminate is relatively slow and requires multiple winding stations to pick up the full width of the stripped fabric.

In another embodiment, when the package as shown in Figure 1 is compressed and transported to the point of use, the package remains unconnected at the top and bottom ends. At the point of use, instead of connecting the strips of one antagonist to the strips of another adjacent stack to supply a continuous strip from the package, each stack is connected to the corresponding stack of the next adjacent package. Thus, each stack is supplied as a separate strip to the machine used, and the strips of each stack are joined to stacks of different packages for continuous supply of separate strips by stitching at the place of use. The stacks, however, are placed side by side in the package and the bottom strips are exposed with tails as shown in FIG. 1 for connection.

In another configuration similar to that shown in FIGS. 5 and 5 although not shown, alternating tails 45 are disposed at opposite ends of the package structure. In this configuration, it is possible to omit the torsion at the connection and connect the tail directly to the top of the next layer. When the tails are connected without kinks, an automatic torsion effect is generated by disassembling from one layer to the next, causing the band to twist 360 degrees. This torsion is eliminated by torsion in the opposite direction at the next conveyance position.
