Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming decorative wrinkles on a skin used, for example, on the seat and back of a chair.

[Conventional technology]

Conventionally, as shown in FIG. 6, after forming wrinkles 11 on the skin 1, a cylindrical band 8 is brought into contact with the wrinkles 11, and the thread 3 is
The wire is sewn and fixed, and the wire is passed inside the cylindrical band 8.
Wrinkling and drawing processing was performed by using the wire to draw the epidermis inward through the elastic band.

[Problem that the invention seeks to solve]

However, in the conventional method described above, it takes time and effort to form the wrinkles 11, and it is difficult to sew the cylindrical band 8 to the epidermis 1 on which the wrinkles 11 are formed.

[Means for Solving the Problems] As a means for solving the above conventional problems, the present invention provides a cylindrical elastic band 2A in which an elastic yarn is used for the weft and a normal yarn is used for the warp in the longitudinal direction. After fixing to the skin 1 in the stretched state, the skin 1 is returned to the normal state to form wrinkles 11 on the skin 1, and a wire 6 is passed inside the elastic band 2A, and the wire 6 is inserted through the elastic band 2A. This provides a method for pulling out wrinkles 11 from the skin 1 by pulling the skin 1 inward.

[Effect]

The effects of the present invention are as follows.

When a tensile force is applied in the lateral direction to a cylindrical elastic band, the weft threads of the elastic band are elastic threads, so after being stretched in the lateral direction, that is, in the longitudinal direction, and fixed to the epidermis, when the tensile force is removed, the elastic band shrinks and returns to its original state (normal state). At that time, as the elastic band shrinks, the epidermis shrinks and wrinkles are formed. Furthermore, a wire is passed inside the elastic band, and the outer skin is drawn inward by the wire, but since the warp of the elastic band is a normal thread, the elastic band does not extend in the longitudinal direction and draws the outer skin inward. I can do it.

〔Effect of the invention〕

Therefore, in the present invention, since the cylindrical elastic band is fixed to the unwrinkled epidermis by means such as sewing, fixation is easy, and the reduction (return) of the elastic band prevents wrinkles from forming on the epidermis. Because it is formed, wrinkles can be easily formed, and at the same time, the epidermis can be easily drawn inward.

〔Example〕

An embodiment of the present invention is shown in FIGS. 1-5. The cylindrical elastic band 2A is made of a woven fabric using elastic threads for the weft and normal threads for the warp, and expands and contracts only in the transverse direction, that is, in the longitudinal direction. Thus, the elastic band 2
A is stretched in the longitudinal direction and sewn to the back surface of the epidermis 1 with threads 3, and then restored to its normal state to form wrinkles 11 on the epidermis 1. The elastic band 2A has a wire 6 inserted therein, and as shown in FIG. The wrinkle 11 forming part is drawn inward on the epidermis 1 through the elastic band 2A, and the wrinkle 1 is formed as shown in FIG.
The epidermis 1 has a retracting portion 11A in which a numeral 1 is formed.
To provide a chair 8 covered with. In FIG. 3, 81 is a seat, 82 is a backrest, and 83 is a headrest. The elastic band 2A of this embodiment expands and contracts only in the longitudinal direction, so when it is drawn inward by the wire 6, it does not stretch in the longitudinal direction, that is, in the drawing direction, and it is possible to draw the skin 1 inward.

In order to sew the elastic band 2A to the skin 1 in a stretched state, for example, a jig 4 is used as shown in FIG.
The elastic band 2A is stretched and hooked onto the pins 41 at both ends of the jig 4, placed on the skin 1, and sewn with a sewing machine, or as shown in FIG. Roll 2 with elastic band 2A on top
1, the elastic band 2A is taken out from the sewing machine table 1, and stretched by tension rolls 53 and 54, wound onto the roll 22, and passed onto the sewing machine table 51. A method is used in which the outer skin 1 is placed under the sewing machine 2A and sewn using the sewing machine main body 52.
