Definitions

  • the method of spreading patterned sheet materials for automatic match-up and cutting covered by this patent allows several superimposed layers of patterned materials to be spread in such a way that any distortions present in the pattern can be corrected, thus guaranteeing that the pattern always occupies the same position in all the layers, and that any lines present in the pattern (striped or checked materials) are straight and, where applicable, orthogonal, and allowing material already spread to be moved from the spread table to the cutting table without losing the alignment of the pattern in all the various layers.
  • match-up is used to indi­cate that the pattern occupies a position in each of the pieces that ensures that the pattern in the finished gar­ment will present the desired continuity or symmetry.
  • the method for spreading patterned sheet material for automatic match-up and cutting covered by this invention provides a solution to this problem, allowing several super-imposed layers of patterned sheet material to be spread on top of one another in such a way that any distortions present in the pattern are corrected, thus guaranteeing that the pattern occupies the same position in all layers, as well as ensuring that any lines in the pattern, (striped or check materials) are either straight or, where desired, orthogonal.
  • this method for spreading materials allows material which has already been spread (spreading lay) to be moved from the spread table to the cutting table without losing the alignment of the pattern in all the various layers, before going on to match up and cut the material, using automatic processes, with the pattern always remaining perfectly aligned and any lines remaining perfectly straight and/or orthogonal, throughout the operation.
  • the method also seeks to minimise both the amount and the complexity of any manual operations to reduce as far as possible their repercussion on overall production costs, thereby enabling this method to be used for industrial applications.
  • the spikes are pushed through a sufficiently rigid laminar material until they occupy the positions assigned to them. This may be done by driving the spikes through the same support (paper, cardboard, etc.) of the pattern used in the preceding operation. In this way, one can ensure that the spikes are in the positions they are intended to occupy and they they will not change their position at any point during the process.
  • eachspike pierces all the layers at the same point in the pattern, and also makes any spikes lying in straight lines parallel to any of the edges of the material pierce all the layers at points in the pattern that like­wise define straight lines parallel to the edge of the material.
  • the spikes continue to hold all the layers of the material in place. Once on the cutting table, there is no need to remove the spikes due to the fact, mentioned above, that they are themselves able to be cut. Thus the alignment of the pattern is assured in all the layers until all the pieces have been cut.
  • This makes it possible to apply automatic match-up techniques, with the aim of adjusting the position of each piece to be matched up on the basis of the true position occupied by the pattern in the top layer of the material, since the material-spreding technique described herein ensures that the pattern will occupy this same position in all the other layers.
  • Figure 1 shows a small-scale example of a layout of pieces (some identified by the numbers 11, 12, 13 and 14) which are ready for cutting out of patterned material. This figure shows pieces which make up a garment, but the process can be equally applied to other industrial processes outside the clothing industry in which patterned materials have to be cut (upholstery, footwear, etc.).
  • Figure 1 shows the hypothetical distribution of the points occupied by the match-up points for each piece, these being indicated by small triangles (e.g. 23). In this figure it will also be observed that it is possible for some pieces to have no match-up assigned to them.
  • a series of match-up requirements might be applicable between all the pieces shown in Figure 1. For example, it could be that piece 13 should present the same pattern position at point 18 as piece 12 and point 19, or, alter­natively, that piece 11 should present the same pattern position at point 21 as piece 20 at point 22. The reason for this would be that these pieces will be joined up in the final ensemble and that continuity of the pattern will be necessary at these points to satisfy quality-of-­finish requirements.
  • Figure 2 shows (at reduced scale) a variation consisting of a life-size diagram of all the pieces to be cut, some of which are referenced by the numbes 31, 32, 33 and 34, preferably with an indication of the match-up points defined for them.
  • a rectangular grid with equally spaced lines (36) along the X (37) and Y (38) axes has been superimposed over this diagram. The usefulness of this grid and its con­tribution to the spread method in question will be examined later.
  • the spacing of the grid lines along the X and Y axes should preferably coincide, although this is not absolutely necessary, with the spacing of the pattern on the material in these two directions, as long as the pattern, as is often the case, is repeated at regular intervals along these axes.
  • these spikes can be fitted with a flat, horizontal base and a fixed perpendicular needle (52) in such a way that, when the assembly rests on its flat base, the needle remains in a vertical position.
  • the point of the needle (53) must be sharp, to enable the spike to penetrate the material without damaging it.
  • the height of the spike is not relevant to the definition of the method, but it should range between a minimum that will allow easy pene­tration of the material and a maximum that will not impede the movement of the head with which automatic cutting machines are usually equipped, since these spikes continue to pierce the material throughout the cutting operation.
  • these spikes are made of a material that is sufficiently rigid on the one hand to hold the material in place in the correct position, and yet is sufficiently soft on the other hand to be cut by the cutting tool used in the cutting machine, (e.g. a blade).
  • the dimensions and shape of the flat base are not relevant either, but they should also be capable of being cut by the cutting tool in use.
  • the need for the spikes to be cuttable is due to the fact that, as will be seen in greater detail further on, the spikes are not removed from the spreading lay when this is transferred to the cutting table but instead remain in the layer throughout the operation, in the course of which they may be cut and are, therefore, disposable. Nevertheless, any spikes which are not cut because they do not happen to lie in the path of the cutting tool may be recovered and re-used in further spread operations.
  • one way to achieve these aims is by placing the spikes in lines or at the cross-points of the grid the lie closest to the match-up points or areas of the pieces.
  • the advantage of placing the spikes on the lines or cross-points of the grid is that this produces the greatest number of aligned spikes (objective no. 2).
  • the spacing of the grid is suitable, it may also be possible to achieve objective no. 4, that of not placing the spikes too close together, since the distance bewteen any two spikes will be at least that of the spacing along the X or Y axis.
  • two of the match-up points (40 and 41) have been replaced by a single spike (39) which has been placed at one of the grid cross-points.
  • the latter can be placed at the appropriate points. To ensure that the spikes do not change their relative positions during the remaining stages of the spread operation, these are now fixed in place. This is done by pushing them through a layer of laminar material sufficiently rigid for this purpose.
  • this will be paper, but it may also be plastic, cardboard or any other laminar material with enough rigidity to ensure that the spikes to not move with respect to each other. If the cutting machine to be used employs a suction device to hold the cloth, the laminar material should also be air permeable to ensure the efficacy of the suction device.
  • FIG. 4 is a cross-section diagram of a spreading lay.
  • the first layer (47) which is pierced by the spikes (49) is precisely the layer referred to above, the purpose of which is to fix the positions of the spikes and which may consist of the same drawing used to define these positions in the first place.
  • the layers of material to be simultaneously cut (48) may then be "impaled" into place. To do this, it is only necessary to ensure that each spike penetrates all the layers of material at the same point in the pattern, and also make each spike defined for straight lines parallel to either the X or Y axis pierce the material at points that also define straight lines in the pattern that are parallel to the edges of the cloth. In this way, as has already been mentioned several times above, not only can one ensure that the pattern always occupies the same position in all the layers, but also that the pattern meets all the pertinent requirements of straightness and orthogonality.
  • Figure 6 shows in a perspective view the different layers after spreading. It can be seen how the pattern in all layers lies in the same position and how each spike pierce all the layers of the material at exactly the same point of the pattern.
  • the spikes are aligned along straight lines parallel to either X of Y axis, thus facilitating the spread affordation, especially when the lines defined by the spike coincide with lines in the material.
  • This refers to very usual cases like checked or striped fabrics, in which there are lines in the pattern wich run parallel to the edge of the material. In these cases it is very useful for the spread operation if two or more spikes are in lines also parallel to one of the edges. This allows the operator to take this line as a reference line for the spreading operation, and, in this way, he or she can compensate lack of straightness or orthogonality of the material just piercing the spikes in the same line of the pattern.
  • the spacing between the X and Y lines of the grid 36 in Figure 2 represents the minimum allowable distance between spikes if the spikes are placed on the cross-point of the grid. If the pattern is not repeated at regular intervals, this spacing can be determined in an empirical way in order to guarantee that one spike ensures the perfect alignment of the pattern in all the layers not only at the point at which it is placed, but also in an area around it corresponding to this spacing.
  • a typical value for the spacing is 5 cm, but it will depend on the characteristics of the material, its distorsions, its lack of straightness etc., and also on the quality of the spreading operation. Again the spacing is not a critical point in the method described.
  • the spread operation itself is made manually.
  • One or more operators pierce each of the material layers in such a way that guarantees that one spike pierces all the layers on the same point of the pattern. And in such a way that spikes which are in lines pierce the material in the same line of the pat­tern to correct misalignment of the material. (Case of checked or striped materials).
  • the next step is to transfer the spreading lay to the cutting table for the match-up operation - if a match-up system is available - and the cutting process.
  • another layer 46 which may be of any laminar material like paper, cardboard, plastics, etc..
  • the purpose of this layer which, when used, is the first to be spread on the spread table, is to facilitate the transfer of the whole spreading lay from the spread table to the cutting table without the base of any spike snagging on any projection during the course of this operation, since this would seriously impede the transfer operation and, worse still, might disarrange the relative position of these spikes.
  • this lower layer is limited to the transfer operation and, if desired, it may be removed once the spread pattern has been placed on the cutting table.
  • the "spreading lay” formed in the described way can be moved to the cutting table manually or with the help of some auto­matic mechanism. During this operation the pattern keeps on the same position without suffering any movement. This can be ensured because of several reasons: First of all the transfer operation from the spreading table to the cutting table is carried out by pulling the "spreading lay" from the bottom laminar material 46 which supports all the “spreading lay”; in this way no force is applied to the different layers of material; second the material is perfectly fixed by means of the spikes; third no spike will snag on any projection during the course of this operation thanks to this bottom laminar material. This transfer operation is not needed if the spread operation is carried out directly on the cutting table. This is possible, but it is not advisable because this means to occupy the cutting table during the spread operation, which can be much longer than the cutting operation.
  • the spikes remain in their assigned positions throughout the whole spread, match-up and cutting operation. This is possible thanks to the spikes being made of a material that can be cut by the cutting tool itself. The fact that these spikes remain in their original positions throughout the process is what makes it possible to match-up the various pieces in all the layers contained in the spread­ing lay once they have been matched up on the top layer.
