ものであった。In the above-mentioned uses, etc., there is a demand for a material with a concavo-convex pattern due to seasonality and sunlight. Among them, those with a wavy, wrinkled, uneven pattern are sensually preferred and welcomed in some cases. Conventionally, the method of manufacturing a laminate with a wrinkled uneven pattern is to simply adhesively laminate a foam sheet and a top sheet material, and then pass this through an embossing roll or the like to give it a wrinkled uneven pattern. It was something.

製造方法にある。That is, the method for manufacturing a laminate having a wrinkled uneven pattern according to the present invention involves adhesively laminating a flexible sheet material on one or both sides of an elastic foam sheet while applying tension in a plane direction to the elastic foam sheet. The laminate is later made tension-free and shrinks to reveal an uneven pattern. Another gist of the present invention is to adhesively laminate a flexible sheet material on one side of the elastic foam sheet while applying tension in the plane direction to the elastic foam sheet,
Thereafter, the laminate is made tension-free and shriveled to reveal an uneven pattern, and further, a backing material is adhesively laminated on the opposite side of the flexible sheet material of the laminate showing the wrinkled uneven pattern. A method for manufacturing a laminate having an uneven pattern.

。As the elastic foam sheet in the present invention, synthetic resin foam sheets such as flexible polyurethane foam sheets, polyethylene foam sheets, polypropylene foam sheets, and polyvinyl chloride foam sheets, foam rubber sheets, etc. can be used, and the thickness of these sheets is particularly limited. Although it is not recommended, a distance of 1 m to 30 m, preferably 3 m to 5 m is good.

ジン状態を維持することができる。Figure 1 shows the process of adhering and laminating a flexible sheet material on one side of an elastic foam sheet while applying tension in the plane direction, and then releasing the tension on the laminate after binding. This is an example. To apply tension in the planar direction to an elastic foam sheet, if the tension direction is in the longitudinal direction of the foam sheet, the flexible sheet material should be brought into contact with the elastic foam sheet before it is laminated. The Te/Sijin state can be maintained by acting on the fibers to keep them in an appropriately elongated state at all times.

接着可能ならしめるものである。Further, if it is in the middle direction of the foam sheet, tension may be applied using a clip-type tenter or the like. Of course, tension may be applied in both the length direction, width direction, or diagonal direction. What is shown in Figure 1 is mainly a lamination drive roll (1).
The tension is applied to the elastic foam sheet (3) by taking the difference in circumferential speed between the roller and the feed roll (2). Further, the tension may be applied uniformly over the entire surface of the elastic foam sheet or may be applied partially. For those that are partially tensioned, flexible sheet materials are laminated with adhesive, and after the tension is released, a different textured pattern is obtained. In addition, the elongation rate of the elastic foam sheet due to tension is ← Takashi- or higher, and preferably, the flexible sheet material can be bonded to the elastic foam sheet under tension in this manner using an adhesive or by frame lamination. Elasticity 6 - Foamed sheets are laminated using flame lamination. The one shown in Figure 1 uses the flame lamination method, that is, the surface of the elastic foam sheet (3) to be adhesively laminated is made into a molten state by a frame (4), and the sheet (3) is bonded to the surface of the elastic foam sheet (3) with this melt. This makes it possible to bond the flexible sheet material (5).

ものとすることができる。When the lamination is completed and the art materials are being bonded by adhesion, or after the bonding is complete, the tension of the laminate is released and the elastic foam sheet contracts due to its restoring force, and the flexible sheet material adhered to the outer surface of the foam sheet A shriveling uneven pattern appears. Furthermore, if the elastic foam sheet and the flexible sheet material are not tension-free during the adhesive bonding process, a partially adhesive bonded pattern with a soft texture can be formed, which is different from that after the adhesive bonding is completed. It can be a sensory thing.

よい。FIG. 2 shows the elastic foam sheet (3) with the first layer on both sides of the elastic foam sheet (3) under tension in the plane direction.
This shows an example of the process of adhesively laminating the first and second flexible sheet materials (5) and the second flexible sheet material (5), and then releasing the tension of the laminate. In this example, the tenth flexible sheet material (5) and the second flexible sheet material (five) were simultaneously supplied to the elastic foam sheet (3). The first flexible sheet material (5) is first supplied and laminated with one side adhesive, and then the second
flexible sheet materials (5 pieces may be supplied and adhesive laminated.

よい。FIG. 4 shows an example of the step of further adhering and laminating an odorous material (6) to the shrunken concave-convex pattern laminate having a flexible sheet material on one side obtained by the process illustrated in FIG. 1. When laminating with adhesive, it is preferable to carry out the process in an almost tensile-gonless state so as not to eliminate the formed concave and convex pattern. Also, in this case, depending on the thickness and type of the elastic foam sheet, wrinkle-like unevenness may appear on both sides to be bonded. In cases where it is desired to ensure the same, it is advisable to interpose another elastic foam sheet and laminate with adhesive.

いう点で優位である。As the odor material (6) used here, the same material as the above-mentioned flexible sheet material or a sheet material with even less flexibility can be used. A laminate using this odorous material is advantageous in that it prevents curling due to a difference in stress accumulation balance in the laminate, which tends to occur in the single-sided flexible sheet material laminate described above.

ールをするだけで済むため極めて能率的である。As described above, according to the method of the present invention, a laminate exhibiting a shrunk uneven pattern can be produced without using expensive embossing equipment. Moreover, unlike the embossing method, there is no heating and pressing process, so there is no need to worry about deterioration or discoloration of the top sheet material, and high quality products can be obtained. In addition, in terms of the manufacturing process, it is extremely efficient because it does not require the conventional step of adding a concavo-convex pattern after adhesive lamination, that is, it is only necessary to control the tension of the elastic foam sheet during the lamination process.
