Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a covering material for a seat, etc. More specifically, the present invention relates to a method for manufacturing a covering material for a seat, etc., and more specifically, a step of supplying a woven fabric as a backing fabric from a woven fabric supplying device; The present invention relates to a method of manufacturing a covering material for a seat or the like, which includes the steps of laminating a synthetic resin skin formed into a film by a synthetic resin molding machine on one side, and joining the woven fabric and the skin.

Some conventional facing materials use a woven fabric such as stockinette as the backing fabric, and the facing material is formed by bonding a synthetic resin skin to this woven fabric, and the vertical and horizontal elongation of the woven fabric Since the ratio differs by about 4 to 5 times, when using it as a covering material for seats, etc., the cutting direction must be determined by considering the vertical and horizontal elongation ratio when cutting the covering material, and in that case, the cutting direction must be determined by considering the elongation rate in the vertical and horizontal directions. Depending on the shape of the seat, for example, in the case of the upholstery of a seat cushion, the main part, a pair of side parts, a so-called belt-like gusset part, etc. are cut by punching or other methods. It has the disadvantage that it is difficult to cut the woven fabric economically, and if the elongation of the woven fabric is not taken into consideration, there is a high risk of damage or cracks occurring when the covering material is used. When covering the outside of a cushion pad such as a seat after cutting and sewing a covering material using a woven fabric that has little elongation in one direction, it is difficult to cover the outside of a cushion pad such as a seat because the elongation in one direction is small. It had some drawbacks.

The purpose of the present invention is to adjust the elongation rate of the facing material by adjusting the elongation rate of the woven fabric when the elongation rate in the vertical and horizontal directions of the woven fabric used as the backing fabric is different, and to adjust the elongation rate of the facing material during cutting and covering work. Without limitation, each part cut according to the shape of the seat etc. can be obtained more efficiently and economically than a series of upholstery materials,
The present invention provides a method for manufacturing a covering material for a seat, etc., which makes it extremely easy to cover a cushion pad with the covering material.

This will become clear from the detailed description below with reference to the drawings.

FIG. 1 schematically shows a manufacturing apparatus for carrying out the method for manufacturing upholstery materials for seats, etc. according to the present invention. It has a supply device 1 for supplying a woven fabric 4 such as stockinette, etc., and a synthetic resin molding machine 5 for supplying a film-like skin 6. The synthetic resin molding machine 5 is a film molding machine using a T-die method or a calendar processing machine. You can use machines etc.

A skin 6 made of a synthetic resin extruded by a synthetic resin molding machine 5 is laminated on the upper surface of the woven fabric 4 supplied from the woven fabric supply device 1, and a joint 7 is provided to join the woven fabric 4 and the skin 6. The cover material 11 is wound around the take-up roll 9 through a surface treatment section 8 such as 7-bore treatment.

A woven fabric 4 having a small elongation rate in the longitudinal direction and a large elongation rate in the lateral direction is wound around the woven fabric storage section 2 of the woven fabric supply device 1, and both sides of the woven fabric 4 are joined. It is held by a tension mechanism 3 provided across the front and rear of the section 7, and is pulled along a guide 3a extending in an oblique direction before reaching the position of a pair of rollers 7a as the joint section 7, as shown in FIG. The woven fabric 4 is stretched in the lateral direction, and the woven fabric 4 is heated by the heating roller 3b as the woven fabric 4 is stretched.
Remove wrinkles and the like that occur in the woven fabric 4. Next, the woven fabric 4 and the outer layer 6
Simultaneously with or after this lamination, a skin 6 made of synthetic resin is bonded to the upper surface of the woven fabric 4 using bonding means such as pressure and heating at the bonding portion 7, thereby forming a facing material 11. . Although detailed explanation of the tension mechanism 3 will be omitted,
A wrapping transmission device is formed along the guide 3a, and a clamping portion is formed at the tip of the chain of the wrapping transmission device, and when this clamping portion is on the side approaching the woven fabric 4, the woven fabric 4 is held in place and released on the other side.

A film-like skin 6 extruded from a synthetic resin molding machine 5
After being cooled, it is wound around a take-up roller, and the skin No. 6 is supplied to the take-up roller, and after being laminated onto a pair of rollers 7a, the skin 6 and the weave are passed through a joint 7 equipped with heating and pressing means, etc. It is also possible to join it to cloth 4. Furthermore, the widths of the outer skin 6 and the woven fabric 4 are set to be the same at the joint portion 7. Furthermore, code 13,1
4 and 15 indicate guide rollers, respectively.

As shown in FIG. 3, when the elongation rate of a woven fabric 4 of a certain size is large in the transverse direction X and small in the longitudinal direction Y, an appropriate tensile force is applied in the transverse direction X according to the percentage of elongation. For example, if a tensile force that consumes about half of the elongation rate is applied, the horizontal direction
The length of is 1. The length in the vertical direction Y is compressed to 82 from Sl, and in this state, the synthetic resin skin 6
When the facing material 11 is formed by joining, it is in a state where it can return to a length of S2-1)S1 in the longitudinal direction Y, where the elongation rate is small, and it has a further small elongation rate in the longitudinal direction Y.

In addition, since the elongation rate remains in proportion to the percentage in the horizontal direction I can do it. Note that by varying the tensile force applied in the lateral direction X, the elongation rate in the vertical and lateral directions can be adjusted.

The above is an outline of one embodiment of the method for manufacturing a covering material for a seat or the like according to the present invention.

It is possible to form the back base fabric using an inexpensive woven fabric that has different elongation rates in the vertical and horizontal directions.At this time, by adjusting the elongation rates in the vertical and horizontal directions of the woven fabric, when it is formed as a facing material, the vertical and horizontal elongation rates of the facing material are adjusted. If the elongation rate is adjusted, and if the elongation rate in the vertical and horizontal directions is approximately equal, then when cutting each part of the seat etc. from a series of upholstery materials, the elongation rate will be adjusted. The upholstery material can be cut efficiently and economically without having to cut the upholstery material, and the covering work of sewing the upholstery material onto the cushion pad can be carried out with great ease.
