The laminate is generally laminated and then wound into a roll for storage, and when used, it is generally taken out from the roll and cut into a required length and shape for use. ing. The roll-up direction is the vertical direction of the laminate, and the width perpendicular to the winding direction is the lateral direction, which will be described below.

に大きな力を要した。In the laminate having the three-layer structure, the length ratio of the front cloth, the foam sheet, and the back cloth in the longitudinal direction before lamination is 1: 1: 1.
Are laminated so that Therefore, when the front cloth and the back cloth are materials that are difficult to stretch in the longitudinal direction or are knitted or woven so that they are hard to stretch, due to the poor spreading of the front cloth and the back cloth regardless of the elongation of the foam sheet, The laminate has poor longitudinal elongation, and when the laminate is used for those requiring longitudinal elongation, required portions, other portions having curved surfaces, etc., it is difficult for the laminate to elongate. Therefore, there are drawbacks such as wrinkles, folds and wrinkles on the surface of the laminate, and sometimes the laminate is torn. Also,
It took a lot more force than necessary because it forcedly stretched and used it.

がかかる等の欠点があった。Further, a laminate formed by using a cloth made of a woven fabric or the like which has a low longitudinal elongation as both the front cloth and the back cloth, but has a good lateral elongation is formed in the lateral direction of the laminated body. Since it has elongation, it was considered to use the lateral direction of the laminate as the longitudinal direction of the product by utilizing the elongation in the lateral direction. For example, in Japanese Unexamined Patent Publication No. 58-38585, when a laminate having the above three-layer structure is used on a side portion of a top plate of a vehicle seat, the minimum tensile stress direction (lateral direction of laminated product) is before and after the seat. It has been proposed to cover the seat by processing so that it is oriented in the direction (that is, the depth direction of the seat portion).
By using the laminate in the horizontal direction as the vertical direction in this manner, it becomes possible to use it in a portion requiring longitudinal extension, and wrinkles are not generated, but the laminate is processed in the horizontal direction. There are drawbacks such as complicated processes that are very time-consuming.

It was considered to be a material having elasticity in both the vertical and horizontal directions. For example, Japanese Utility Model Publication No. 3-37944 proposes a composite sheet (laminate) obtained by laminating a front cloth and a back cloth made of a woven cloth having an elongation of 100% or more in the longitudinal direction and the transverse direction of the foam sheet. Certainly, this laminate has stretchability, and even if it is used for a part that needs stretch or a part with a curved surface, wrinkles, folds, etc. do not occur, but it is used as a front cloth and a back cloth. What can be done is restricted, and a table cloth made of elastic material,
The use of a backing cloth has drawbacks such as an increase in cost.

It is important that it is 1.10. If the ratio of the length in the longitudinal direction is smaller than the above range, elongation cannot be imparted to the laminate, and if it is more than that, wrinkles may occur on the surface of the laminate.

The same length as the longitudinal length (L2) of the body sheet, that is, the ratio is L3 / L
2 may be 1.00, but the length of the backing cloth before lamination (L3) and the length of the foam sheet in the lengthwise direction are the same as for the front cloth regardless of whether they are stretched or not. When the ratio of (L2) is about L3 / L2 = 1.01 to 1.10, it is preferable because elongation can be imparted to those that are elongated and elongation can be imparted to those that are not elongated.

Is preferred. The longitudinal tensile tension of the foam sheet is preferably applied so that the ratio of the length in the longitudinal direction of the foam sheet before lamination and the front cloth, or the length of the foam sheet and the back cloth is within the above range. The longitudinal elongation of the body sheet is 101-110%
It is preferably about the same. Further, when laminating only the top cloth to the foam sheet, it is sufficient to laminate the non-tensioned top cloth to the foam sheet to which tension tension is applied,
When the front cloth and the back cloth are laminated, even if the front cloth and the back cloth are laminated at the same time on the foam sheet subjected to the tensile tension, the front cloth is laminated and then the back cloth is laminated, or the back cloth is laminated. A method of laminating the rear surface cloth may be used, and the method is not particularly limited, but it is preferable to laminate the one having good elongation first, since it can be laminated without being restricted by poor elongation.

When it is set to 1.10, elongation can be imparted to the obtained laminate even when a non-stretchable surface cloth is used, and further elongation than that of the surface cloth or the back cloth itself. Is added. Moreover, no wrinkles are formed on the surface of the laminate. Therefore, the laminated body can be easily stretched, the outer cloth is not liable to be broken, and there is no fear that the wrinkles are generated even when the laminated body is used in a portion having a curved surface. In addition, by laminating the constituent materials having good elongation in the above ratio, the restriction on the elongation of the laminated body due to the constituent material having the worst elongation can be relaxed.

There is no risk of wrinkling, and since it can be used in parts that require longitudinal elongation without applying excessive force, there is no risk of breaking the laminate, and even if this laminate is used for things with curved surfaces, it will not break. There is no risk of wrinkles. By setting the ratio of the length of the foam sheet before lamination (L2) to the length of the front cloth (L1) before lamination to be L1 / L2 = 1.01 to 1.10, the longitudinal elongation as a front cloth is completely reduced. Elongation can be imparted to the obtained laminate by using a material which is not used. Also,
The layered product of the present invention is a layered product which is not restricted by the elongation even when a front cloth or a back cloth made of a constituent material that is hard to stretch or does not stretch is used by being laminated in the above ratio. As a result, the range of things that can be used as front and back cloth has expanded. Further, by being laminated at the above ratio, a laminate having not only longitudinal elongation but lateral elongation is obtained.
