Definitions

  • This invention relates to a package of a continuous strip of material for use in cutting into sheet elements arranged end to end.
  • Strips of material are used for manufacture of diapers and other absorbent products.
  • the strips are cut on the manufacturing line at longitudinally spaced transverse cut lines to divide the strip into individual sheet elements each used in the manufacture of a respective absorbent product.
  • these strips are also die cut to provide different widths for shaping of the products to better match the body of the user and for better aesthetics.
  • Most current processes of this type die cut the elements from a single strip of the material having a width at least equal to the maximum required width and discard the waste at the sides formed by cutting away the side portions to the narrower scalloped width. Attempts are made to recycle the waste portions, generally by grinding and returning the materials to the strip manufacturer.
  • recent developments have increased the complexity of the materials thus increasing the cost and making recycling more difficult. There is therefore pressure to reduce the amount of waste.
  • Previously packages of a continuous strip of material have been formed using a technique known as "festooning" in which the strip is folded back and forth to lay a series of strip portions back and forth with each portion being folded relative to the next about a line transverse to the strip.
  • the technique of festooning has been available for many years and is used in packaging many different types of materials but particularly material of a fibrous nature such as fabric, non-woven strips and the like.
  • the strip is conventionally guided into a receptacle such as a cardboard box while a first reciprocating movement causes portions of the strip to be laid across the receptacle and folded back and forth and a second reciprocating movement causes the positions of the portions to be traversed relative to the receptacle transversely to the portions.
  • the receptacle comprises a rigid rectangular container at least partly of cardboard having a base and four upstanding sides.
  • Festooning can be used for packaging the strips of varying width but this technique has significant disadvantages which inhibit the effectiveness of the product when removed and processed.
  • the fold lines which are essential to the process will interfere with the absorbency or other performance of the material when such fold lines occur at a central area of the sheet element.
  • a method of forming a package of a strip of sheet material comprising: providing a strip of material having a first side edge, a second side edge defining a width therebetween, a first surface and a second surface, the strip having a width across the strip which varies along the length of the strip such that the width of the strip varies from areas of minimum width to areas of maximum width; forming a plurality of stacks of the strip by folding the strip in each stack repeatedly back and forth to form a plurality of folded strip portions of the strip, with each folded strip portion of the strip being folded relative to one next adjacent folded strip portion about a first fold line transverse to the strip and relative to a second next adjacent folded strip portion about a second fold line transverse to the strip and spaced from the first fold line; arranging the folded strip portions of each stack to form a plurality of first fold lines arranged at one of two opposed ends of the stack and a plurality of second fold lines arranged at the other of the ends of the stack; arranging the folded
  • the strip in each stack is continuous from an end connecting portion at one end of the stack to an end connecting portion at an opposed end of the stack and including splicing one end connecting portion of the strip from each stack to an end connecting portion of the strip of the next adjacent stack by a splice connecting portion of the strip so as to form a strip that is continuous along its length through the package.
  • the stacks are substantially upright with a bottom and a top, two sides parallel to the edges of the strips of the stacks and two ends containing the fold lines of the stacks and wherein the end connecting portion of the bottom of a stack is connected to the end connecting portion of the top of a next adjacent stack to form the splice connecting portion which extends along one end of the stack.
  • the package is compressed downwardly so as to decrease the height of the stacks from a rest height to a compressed height; wherein the package is engaged by packaging material which maintains the compression.
  • the compression is sufficient to reduce the thickness of each strip portion of said stacks.
  • the strip is fibrous.
  • the package is wrapped by a flexible packaging material forming a closed bag from which air is withdrawn and which is sealed against ingress of air.
  • the method includes applying to the strip of each stack a series of machine readable markings each located at a longitudinal location on the strip which is arranged to identify a longitudinal location of a respective one of the fold lines; including unfolding the strip; scanning the unfolded strip to locate the machine readable markings; and cutting the unfolded strip by using the machine readable markings to locate cut lines transverse to the strip at or adjacent the fold lines.
  • a method of forming a package of a strip of sheet material comprising: providing a strip of material having a first side edge, a second side edge defining a width therebetween, a first surface and a second surface, the strip having a width across the strip which varies along the length of the strip such that the width of the strip varies from areas of minimum width to areas of maximum width; forming a plurality of stacks of the strip by folding the strip in each stack repeatedly back and forth to form a plurality of folded strip portions of the strip, with each folded strip portion of the strip being folded relative to one next adjacent folded strip portion about a first fold line transverse to the strip and relative to a second next adjacent folded strip portion about a second fold line transverse to the strip and spaced from the first fold line; arranging the folded strip portions of each stack to form a plurality of first fold lines arranged at one of two opposed ends of the stack and a plurality of second fold lines arranged at the other of the ends of the stack;

  • the package comprises a generally rectangular body 10 formed from a strip 11 of a material to be packaged and generally this material will be of a fibrous nature formed by woven or non-woven material although this is not essential to the package structure.
  • Many materials of various thicknesses can be packaged using the festooning technique provided they can accept the creasing necessary at the end of each portion.
  • the package body is formed of a plurality of side by side stacks of the strip where each stack comprises a plurality of folded strip portions of the strip which are laid on top of one another.
  • each stack comprises a plurality of folded strip portions of the strip which are laid on top of one another.
  • the portions are folded back and forth at respective end fold lines 25 and 26 so that the fold lines lie in a common vertical plane defining the ends 15 and 16 of the stack.
  • Each portion of the strip lies directly on top of the previous portion so that side edges 27 and 28 of the portions of the strip define a first set of lines in the common plane at right angles to the strip portions which contain all the side edges 27 of the stack and similarly, the side edges 28 of the strips of the stacks define a second set of lines in the common plane at right angles to the strip portions which contain all the side edges 28 of the stack.
  • the package is formed by stacking the portions each on top of the next from a bottom portion 29 up to a top portion 30 to form the stack.
  • the package is thus formed from the plurality of stacks 12 each of which has a length equal to that of the other stacks and therefore equal to that of the package and the stacks are formed up to a common height which is therefore equal to the height of the package.
  • the package 10 is formed from a plurality of individual stacks 12 arranged side by side. In figure 1 there are shown only three such stacks for convenience of illustration whereas in figure 2 there are shown six such stacks arranged side by side forming a complete package structure. Each stack is formed from a folded strip which is continuous through the stack. Each stack has a top end 13, a bottom end 14, two ends 15 and 16 which are opposed and two sides 17 and 18 which are opposed.
  • the dimensions of the package can be varied in according to the requirements so that the number of stacks can be increased or decreased, the length and height of each stack can be varied to increase the number of folded strip portions and to increase the length of the folded strip portions.
  • the strips of each stack are folded back and forth from the fold lines 25 to the fold lines 26 to form a folded strip portion having a length equal to the distance between the fold lines.
  • the strips are cut so that they have a varying width between the side edges 27 and 28 of the strip.
  • the strips are of a simple form in which the width varies periodically between narrow sections 32 and wider sections 33. More complex width variations can be employed in other example.
  • the strip is intended for manufacturing diapers or similar products which are formed each from a respective sheet element cut from the length of the strip.
  • Each sheet element in the example shown has an intended cut line 34 at the wider section 33 and a second intended cut line 35 also at the wider section 33 so that the narrower section 32 is located between the intended cut lines.
  • the cut lines 34 and 35 are in effect imaginary lines. Their position can however be determined by the design of the sheet elements and the position along the length of the strip which forms the beginning and end of the sheet elements.
  • the sheet elements are in effect thus arranged end to end so that each is separated from the next simply by cutting along the intended cut line.
  • the strip has a varying characteristic along its length which determines the position of the sheet elements on the strip and therefore determines the positions of the intended cut lines. In the example shown the varying characteristic in the varying width. Other characteristics such as additional materials or varying thickness can be used.
  • each folded strip portion of each of the package bodies is defined by an exact whole number of sheet elements.
  • the number of sheet elements is three but this can of course be varied from a minimum of one up to a maximum which depends solely upon to maximum allowable size of the transportable package structure.
  • the folded strip portion will contain more than one sheet element since the sheet elements are often of the order of six inches to two feet in length and the required package structure will be generally significantly larger than this and certainly of the order of four feet in length.
  • the design of the wider and narrower portions of the strip is arranged such that no waste is formed when the slitting action occurs and the wider portions match exactly with the narrower portions of the next strips.
  • the wider portions of one strip and the narrower portions of the next adjacent strip so that so that some waste pieces will be formed by cutting out of the structure and discarding of those waste pieces.
  • the strip portions will nest each exactly along side the next with the narrower portions of one receiving the wider portions of the next.
  • the wider portions do not exactly match the narrower portions, they will still be some nesting effect even though there may be spaces left between the folded strip portions.
  • each folded strip portion contains an exact whole number of sheet elements ensures that the cut lines occur directly at the fold lines. Thus there are no fold lines across the strip in any part of the sheet elements after the sheet elements are cut along the cut lines. This is desirable in that the absence of fold lines in the material of the sheet elements will avoid compromising the performance or absorbency of the sheet element in the main body of the sheet element.
  • the folded strip portion contains a whole number of the sheet elements and the sheet elements are identical ensures that the side edges of the each folded strip portion lie directly on top of the side edges of the previously laid folded strip portions. There are no overhanging or feathered edge portions therefore and all parts of the strip are fully contained within the stack.
  • the stack is therefore in effect a solid structure having a constant density across its width. When compressed therefore the stack can form a very rigid structure with no possibility of damaging the side edges of the strip or of interleaving any material between the side edges of the strip.
  • each stack is off set by one half of the length of the sheet element.
  • the fold line 25A of the sheet element 12A is off set from the fold line 25 and the sheet element 12 by a distance equal to one half of the length of the sheet element from the fold line 25A to the cut line 34.
  • the nesting effect of the stack provides an integral package structure when these are brought together and wrapped by the packaging material as described hereinafter.
  • an alternative arrangement can be provided in which the position of the fold lines relative to the sheet elements is of less importance and it is possible to accept a fold line 35A at a position along the length of the sheet element different from the intended cut line 35.
  • the fold lines are aligned but the sheet elements are longitudinally offset.
  • the package structure can be directly rectangular apart from the outside edges which are shaped to follow the side edges of the outermost package bodies.
  • the package is wrapped by a flexible packaging material preferably of heat sealable non-permeable plastics which encompasses the whole of the package as indicated at 40 (not shown in figure 1).
  • the packaging material forms a sealed package which allows air to be extracted from the package and this vacuum action can be used with physical compression D from the top and bottom 13 and 14 of the package so as to compress the package to a reduced height in a vacuum packaging system.
  • the amount of compression can be determined so as to minimize the volume of the package without interfering with the required loft of the product when withdrawn from the package.
  • the package structure avoids the necessity for rigid sides of a box or similar container so the package structure is stable due to the compression of the layers to reduce the height of the layers and due to the pressure of each layer against the sides of the next adjacent layers.
  • Compression of the package is only possible in the direction D which is at right angles to the surfaces of the portions of the strip. This acts to compress the height of the stacks so that the thickness of each strip portion in the direction D is reduced by that compression. Compression along the portions or at right angles to the stacks is not possible since this will act to distort the strip.
  • Mechanical compression therefore of the package in the direction D thus reduces the dimension of the package in that direction allowing the air to be withdrawn from the flexible packaging material 40 causing the packaging material to be pulled down onto the package to maintain it in its compressed condition and to apply pressures tending to hold the stacks in intimate contact. Further detail of the packaging and compression arrangement are shown in the above applications.
  • the strip of each layer is connected to the next by a traverse or spliced portion of the strip which extends from one stack to the next so as to form a continuous strip through the full length of the package.
  • the technique for connecting the strip of each stack to the next layer is shown and described in more detail in the above applications and is shown in figure 7.
  • the spliced portion is simply omitted for convenience of illustration.
  • four stacks 222, 201 , 202 and 203 are shown.
  • the strip of each stack is continuous from a top strip portion 205 to a bottom strip portion 206.
  • the connection is effected by a tail portion 208 which extends from the bottom portion 206 beyond one end of the stack.
  • the portion 208 extends along the end of the stack at 216 and includes a twist 215 with fold lines 213 and 214 to form a portion 217 extending along the end of the next adjacent stack.
  • the portion 217 is connected by a splice 211 to the top portion 205 of the next adjacent stack.
  • Other splicing arrangements are possible as described in more detail in the above copending applications.
  • a web 50 is supplied on a master roll 51 and is unwound from the master roll by a feeding and guide system 52 including two nip roller pairs 53 and 54.
  • a slitting system 55 is mounted transversely to the web for dividing the web into a plurality of parallel side by side strips. This can be provided a by a slitter bar which carries a plurality of slitter knives at transversely spaced positions so as to slit the web into a plurality of strips 57 which are carried forwardly by the guide system 52 so that they are maintained in the common plane of the web and are maintained edge to edge.
  • the slitting system comprises a die cutting roller 56 which rolls on a platen 56A so as to cut the strips into the wider and narrower portions described hereinbefore.
  • the strips 57 are split apart by a suitable guide system well known to one skill in the art and alternate ones of the strips are passed over a diverting roller 91 which increases the path length by a distance equal to one half of the length of a sheet element so as the strips pass through the guide rollers 58 they are aligned into the position shown in figure 5.

  • the table 60 is mounted upon a jacking system 61 which is shown only schematically and acts to raise and lower the table so that the table is gradually lowered as the strips are folded onto the table.

  • the marking may or may not be located directly at the cut line depending upon the location of the machine reader relative to the cutting blade and in the example shown, the marking is located in advance of the intended cut line.
  • the marking may extend only across a short part of the width of the strip. It will be appreciated that as the markings are registered with respective ones of the cut lines, each marking is offset from its associated cut line by the same distance. In an arrangement in which only the fold lines are marked by the ink jet marking, there will be only one marking on each strip portion. In an arrangement in which the number of sheet elements on each strip portion is a whole number greater than one, each intended cut line can be marked and therefore there will be a plurality of markings on each strip portion.
