A positioning mechanism, as provided by the system shown by the steering rollers 78, operatively locates and transfers the cooperating tissue layer, in motion 26 in a face-to-face relationship. , and superimposed with the primary tissue layer, which moves 24. At the process and apparatus site where the cooperating tissue layer 26 and the primary tissue layer 24 are operatively brought together for further processing, each one of the layers of primary tissue and tissue are substantially continuously directed along the designated machine direction 28 of the process and the apparatus.
For the purposes of the present invention, a named component region is operatively synchronized with another, the second component region, when the selected 5-component regions are configured. and arranged to move at substantially the same speed and in substantially the same direction. The regions of selected components may or may not be in physical contact with each other during the synchronized condition. Also, the regions of 10 selected components may or may not be fixed with each other during the synchronized condition.
In a particular aspect, the synchronization of the first edge region 32 of the primary tissue layer 24 to the The third edge region 36 of the cooperative tissue layer 26 may include an operative fastening to the first edge region 32 to the third edge region 36 along the first region 40, as representatively shown in Figure 2.

In the configurations shown 5 representatively, for example, the first junction region 40 and the second junction region 42 may each extend. ~ 'z -. Ar '' x • "ZzSz -:. * 'And ~' - 'X- - *" jéíf f substantially longitudinally along the machine direction 28 of the process and the apparatus. The fastening operation can provide a substantially direct fastener 98, or an indirect fastener.
With reference to Figure 2, the synchronization of the first edge region 32 of the primary tissue layer to the third edge region 36 of the tissue layer cooperating with the direct coupling 98 may include a first, substantially permanent fixation to the first edge region to the third edge region along the first joint region 40. Alternatively, synchronization of the first edge region 32 of the primary tissue layer with the third edge region 36 of the tissue layer Cooperator may include a temporary fastening of the first edge region to the third edge region along the first joint region 40.
Similarly, the synchronization of the second edge region 34 of the primary tissue layer to the edge region 38 of the tissue layer cooperating with the direct attachment 98 may include a second, substantially permanent fixation of the second region of edge to the fourth region of the bank along the second junction region 42. Alternatively, the synchronization of the second edge region 34 of the primary tissue layer with the fourth edge region 38 of the cooperating tissue layer can including a temporary fastening of the second edge region to the fourth edge region along the second joint region 42.
The arrangement and configuration of the direct clamping mechanism can be substantially continuous, or it can; be intermittent with a regular or irregular pattern, as required. Additionally, the clamping mechanism can be of any operational type, such as adhesive joints, thermal joints, sonic joints, welds, pins, staples, sewing, knitting and the like, as well as the combinations of them. In the illustrated arrangement, for example, the clamping mechanism includes the adhesive bonds 80 formed through the operation of the adhesive applicators shown 94.
Various types of conventional techniques for depositing or applying, or for forming the synchronized laminate fabric 44 can be employed. For example, techniques for air deposition such as spraying, melt blowing, swirling or the like can be used, as well as the combinations thereof. Alternativame > Therefore, various contact techniques, such as slot adhesive, pearl coating, or photogravure coating on the substrates can be used.
With reference to Figures 4 to 5A, the synchronization of the first edge region 32 of the primary tissue layer to the third edge region 36 of the layer of tissue cooperating with an indirect coupling can, for example, include at least a connector member, provided separately 96 which is interposed between the first side edge region 32 of the primary tissue layer and the third side edge region 36 of the cooperating woven layer along the first attachment region 40. Similarly, another connector member, provided separately 96 can be interposed between the second side edge region 34 of the primary tissue layer and the fourth side edge region 38 of the cooperating tissue layer along the second joining region 42. Each of the connector members extends substantially longitudinally in the machine direction 28 along their corresponding joint region 40 or 42, and may be of equal or unequal size along their transverse directions 30. Members connectors may extend longitudinally in a substantially continuous or discontinuous configuration, as desired, to provide the synchronized laminated fabric 44. In the arrangement of Figure 4, for example, the connector member 96 may be bent into a C-shape which is convex in the laterally exterior direction.
The examples of the configurations of the connector member 96 are shown representatively in FIGS. 6 through 6C. More particularly, Figure 6 representatively shows a pair of connector members 96 which are bent into a C shape which is concave in the laterally outer direction, and are located in each of the joining regions 40 and 42. Additionally, the C-shaped connector member is attached to the lateral surfaces inward of the corresponding portions of the primary tissue layer and the cooperating tissue layer. Figure 6A representatively shows a unitary connector member, of: a piece which extends across the width of the transverse direction of the synchronized fabric 44 and is located in both of the joining regions 40 and 42. Figure 6B representatively shows a pair of connector members provided separately, one of which is located in each joint region. Each connector member is in the form of a sheet layer arranged substantially parallel to the primary and cooperating tissue layers 24 and 26. Figure 6C representatively shows another pair of connector members 96 which are bent into a C shape and They are convex in the laterally outer direction. Each bent connector member is attached to the lateral surfaces outwardly of the primary and cooperating tissue layers 24 and 26 in their corresponding attachment regions 40 and 42.
Referring again to Figures 1, 2 and 3, a selected splitting mechanism 82 can separate the laminated fabric 44 along a serpentine dividing line 46 which extends longitudinally in the machine direction 28 along the length of an intermediate section located 60 of the laminated fabric 44, and undulates laterally side by side with a pattern that repeats periodically and cyclically. The repeating pattern provides a first pattern segment 86, and a second pattern segment, directionally opposite and transverse 88, the which undulates back and forth substantially in a regular pattern that repeats cyclically. The dividing mechanism can be provided by the cutter 82 illustrated. Suitable cutting mechanisms may include die cutters, water cutters, laser cutters or others power beam cutters, and the like, as well as combinations thereof. The serpentine division line can be continuously curvilinear, or it can be composed of an interconnected series of individual straight line parts, or individual arched line parts, as well as the combinations thereof.
Where the technique of the invention is configured to provide individual shaped articles 100, the synchronized tissue 44 can define a plurality Interconnected of the sections of article 101 along the mechanical direction 28, as shown representatively in the ^ .jy ^^^^^ ^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^ FIGURES 7 and 8. More particularly, FIGURE 7 representatively shows a configuration in which the individual shaped articles 100 are intended to have a longitudinal symmetry (with substantially married-shaped piles that combine at the longitudinal ends, and opposite of the article). In an arrangement of Figure 7, the repeating pattern of the serpentine dividing line 46 can provide a first pattern segment 86, and a second longitudinally adjacent pattern segment 88. The second pattern segment 88 longitudinally identical in relation to the pattern segment. first pattern segment 86. Therefore, when observing the individual length dimensions of the two pattern segments along the same machine direction, the second pattern segment 88 is observed as being substantially identical to the first segment. of pattern 86, but it is observed that it is "flipped" in the longitudinal direction, in a manner which provides the arrangement of a substantially identical configuration in the longitudinal direction, as compared to the first pattern segment.
With reference to Figure 8, another aspect of the invention can be configured to provide the article formed with a desired non-symmetry along the machine and longitudinal direction. To provide longitudinal asymmetry, the splitting mechanism can be configured to separate the laminated fabric 44 along a dividing line serpentine, variegated, distinctive 46. The variegated division line, of multiple section 46 extends longitudinally in the machine direction 28 along the indicated midsection 60 of the laminated fabric 44, and undulates laterally on the 5 side with a pattern that repeats itself periodically and cyclically. The repeating pattern provides a first pattern segment 86, and a second pattern segment, longitudinally adjacent 88. The second pattern segment is distinct from the first pattern segment, and is not longitudinally symmetrical with the first pattern segment.
The first pattern segment 86 of the selected variegated poltron has a first return and return return configuration which traverses through a first angle 87, and the second pattern segment 88 of the selected variegated pattern has a second backward and backward Ccimbio configuration which traverses through a second angle 89. The second angle of return change differs from the first return angle, and it can be relatively greater or less than the first angle of the return change. As a result, the variegated dividing line 46 can advantageously provide for the production of individually formed articles having a pair of longitudinally opposed end portions which differ from one another.
With reference to Figures 1 and 9, the various configurations of the invention can include an appropriate relocation mechanism 84 which can operatively pivot either or both of the first and second parts 56 and 58 of the cooperating tissue layer. 26 around the first and second junction regions 40 and 42, respectively. Equivalently, the relocation mechanism can pivot either one or both of the first and second parts 52 and E > 4 of the primary tissue layer 24 around the first and second joining regions 40 and 42, respectively. The relocation mechanism 84 can, for example, be provided by means of a folding board, a splitting board, an air jet system which blows by opening the first and second parts, a vacuum system and opens the first parts. and second, or similar, as well as combinations thereof.
In a particular aspect of the invention, the pivoting of the first portion 56 of the layer of cooperating tissue 26 around the first attachment region 40 to lie laterally on one side of the first portion 52 of the primary tissue layer 24 is configured to provide the first contoured fabric 90 with bilateral symmetry in the transverse direction 30. Similarly, the pivoting of the second part 58 of the layer of cooperative tissue 26 around the second attachment region 42 for lateral rest adjacent to the second portion 54 of the primary tissue layer 24 can be configured to provide the second contoured tissue 92 with bilateral symmetry.
Additionally, the pivoting of the first part 56 of the layer of cooperating tissue 26 about the first joint region 40 can be configured to provide the first contoured fabric 90 with a predetermined longitudinal variation along the machine direction 28. Similarly, the pivoting of the second part 58 of the layer of cooperating tissue 26 around the second joining region 42 can be configured to provide the second contoured tissue 92 with the predetermined longitudinal variation desired. Desirably, the longitudinal variation in the longitudinal direction may directly correspond to at least two different patterned segments 86 and 88 provided in the repeating pattern of the variegated serpentine division line, previously described [46].
The process and apparatus of the invention can provide a synchronization of the primary and cooperative tissue layers 24 and 24 without indirect or direct attachment of the primary tissue layer to the cooperating tissue layer, as illustrated in the figure. 10. Therefore, the coordinating mechanism 80 operatively maintains the primary tissue layer and the cooperating tissue layer along the joining regions 40 and 42 in a manner in which they simultaneously maintain the simultaneous movement desired. ? -in substantially the same speeds and direction. Suitable coordinating mechanisms can, for example, include pairs of pressure point rollers, movable clamps, air jets, pneumatic pressure devices, vacuum suction devices, devices that produce electrostatic attraction, devices that produce magnetic attraction and the like, as well as combinations thereof.

As illustrated in FIGS. 3, 12 and 13, each contoured woven article 90 and / or 92 may have a plurality of convex, alternating outer regions 110 and concave outer regions 112. Additionally, in the various configurations of the invention, each tissue item contoured 90 and / or 92 may be divided with the selected disconnecting mecha- nism 83 along its transverse direction 30 to provide a plurality of individual shaped articles 100. Desirably, the convoluted fabric is directionally divided transversely into a plurality of said regions. convex outlets 110 to provide the plurality of the individual shaped articles. In other desired aspects, each of the individual formed articles 100 may be longitudinally non-symmetrical along its longitudinal, machine direction 28 (eg, Figures 12 and 13).

The tubular member may be operatively flattened to provide the synchronized laminated fabric 44. The flattened honeycomb has a pair of side-opposite, folded, side-by-side regions 116 and 118 which correspond to the first and second joined regions previously described: of the laminated fabric 44. In the desired arrangements, the folded edges are substantially seamless. The flattened member can be separated along the serpentine dividing line 46 of the invention to provide the first composite fabric 48 and the second composite fabric 50. The first composite fabric has a first upper part of the tubular member 114 combined with a first lower part of the tubular member. Similarly, the second composite fabric has a second upper part of the tubular member 114 combined with a second lower part of the tubular member.
With reference to Figure 15, the first part of the composite fabric 48 can be pivoted substantially around the first bent edge region 116 to ^ _ ^ _ _ _. ^. ^^ «^^^^^^^^^^^^^ - ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Similarly, the second, upper part of the second composite fabric 50 can be pivoted substantially around the second folded edge region 118 to rest laterally on one side of said second lower part of the second composite fabric to form the second composite fabric 92. , the contoured fabrics can be divided along their transverse directions to provide the individual shaped articles having the previously described shapes.
The aspect of the invention which employs the tubular member 114 can provide the contoured tissues 90 and 92 in a configuration which does not have a seam extended longitudinally along the middle portions of the contoured tissues. Similarly, the incorporation of the tubular member can provide the individually wrapped articles 100 with a configuration which does not have a seam extending longitudinally along the middle portions of the individual shaped articles.
