Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a trim cover having gathers on its surface.

2. Description of the Related Art Generally, in a trim cover for forming a seat for vehicles, furniture, and the like, there is a trim cover having a gather on its surface in order to enhance the appearance of the seat.

Conventionally, this type of gather is usually formed by sewing on a skin material before laminating it on a wadding material, or it is usually shaped with a rubber tape that is reduced after sewn a stretched rubber tape on the back surface of the skin material, A trim cover is manufactured by integrally bonding the skin material with a wadding material and a backing material.

Problems to be Solved by the Invention However, in these manufacturing methods, not only the number of steps is extremely high but the cost is increased, but also the gather shape varies depending on how the sewing machine is hung and the rubber is fed. Since the gather is shaped, the skin material cannot be laminated on the wadding material, so that the display material moves greatly with sitting and the gather pattern is easily broken.

Means for Solving the Problems In the method for manufacturing a trim cover according to the present invention, after laminating a backing material having elasticity on the back surface of the wading material, the wadding material is partially stretched to a desired width at an appropriate position. Pull from the left and right, place the skin material on the surface of the wadding material, form a concave pattern at the required part except the tensile part, at the same time laminate the skin material to the wading material, and then release the tension of the wading material Then, a gather is formed in the tensile portion.

Working This trim cover manufacturing method requires a lot of man-hours because the wadding material is partially stretched and the surface is laminated with a skin material, and at the same time, patterning is performed and then the stretching of the wadding material is released to form gathers. Not only that, but because gathers can be formed on the skin material laminated to the wadding material, it is possible to shape gathers that do not easily deform.

Embodiments The following will be described with reference to the accompanying drawings.

In the illustrated embodiment, the skin material, the wadding material, and the backing material are joined together in three parts, and a trim cover for a sheet in which a wading pattern is formed in a concave pattern on the surface thereof is manufactured.

A urethane slab or the like cut into a predetermined size is used as a wadding material 1 for forming the trim cover, and a backing material 2 having elasticity such as nylon half or wooly nylon is provided on the back surface side thereof as shown in FIG. 1a. Laminate in advance. Next, this wadding material 1 is supported and pulled by a jig P such as a clip or a clip from the right and left at regular intervals as shown in FIG. Fig. 1c while maintaining its tensioned state
As shown by (1), the skin material 3 is placed on the surface of the wadding material 1, and the skin material 3 is subjected to the heat pressing treatment. In the hot pressing, the concave patterns 4, 4 ... In which the wadding material 1 is compressed are formed in the middle of the tension portion in the lateral direction, and at the same time, the skin material 3 is laminated on the wadding material 1. After the hot pressing is completed, the tension of the wadding material 1 is released. When the tension is released, the wadding material 1 is reduced to its original shape. Therefore, the surplus material corresponding to the stretched width of the wading material 1 is used as the skin material 3
The gathers 5 can be formed on the surface of the as shown in FIG. In addition, in the shaped portions of the concave patterns 4, 4, ..., there are unnecessary portions of the skin material 3 on the left and right, which are to be cut off when the trim cover obtained as described above is cut and formed into a required shape. it can.

In the trim cover manufactured in this way, the wadding material 1
Since the gathers 5 are formed on the surface of the skin material 3 laminated on the above, since the inside of the gathers 5 is filled with the wadding material 1, it is possible to form the shape having good shape retention and not easily deformed. In addition, it can be formed with accurate dimensional accuracy by compression molding with a mold, and can be formed without requiring a lot of man-hours by patterning simultaneously with laminating the skin material 1. In addition, the gathers 5 can not only be formed in a constant shape by making the pulling width of the wadding material 1 constant, but also the skin material 3 of the same piece can be arbitrarily deformed by changing the pulling width of the wading material 1. Easy to do.

EFFECTS OF THE INVENTION As described above, according to the method for manufacturing a trim cover of the present invention, it is possible to extremely easily manufacture a trim cover having high use durability without easily gathering the gather. is there.

[Brief description of drawings]

1A to 1C are explanatory views showing a manufacturing process of a trim cover according to the present invention, and FIG. 2 is a partial perspective view of a trim cover manufactured by the same method. 1: wadding material, 2: lining material, 3: skin material, 4, 4…: concave pattern, 5: gather.

Claims (1)

[Claims] 1. A backing material having elasticity is laminated on the back surface of the wading material, and then the wading material is pulled from right and left at appropriate places so as to partially extend the desired width, and a skin material is placed on the surface of the wading material. It is characterized in that a concave pattern is formed at the required places except the tension part and at the same time the skin material is laminated on the wadding material and then the tension of the wading material is released to form gathers in the tension part. And method for manufacturing trim cover.
