。(Prior Art) Automotive interior materials whose decorative properties are improved by covering the surface of a base material with an ornamental fabric and a synthetic resin skin material are known from Japanese Patent Publication No. 59-24008, etc.; For automatic refrigerator interior materials, after pasting an ornament fabric on the surface of the base material, a synthetic resin skin material is set, and the synthetic resin skin material is pressed against the periphery of the ornament fabric using a high-frequency welding tooth mold to form an ornament fabric lifter. While crushing, the raised part is entangled with the molten resin of the synthetic resin skin material to be joined and integrated (problem to be solved by the invention). The joint part between and the synthetic resin skin material is
Since it is applied to the raised part of the ornament fabric lifter, the bonding strength is insufficient, and during high-frequency welding, an electric field concentrates at the end of the raised light, generating sparks that may cause the molten resin to fly away or cause damage around the welded part. There is a problem in that many product defects such as whitening phenomenon occur due to the falling of the brushed hair.

うえ基材（３）を受型（１２）より外して製品とする。The base material used in the present invention may be a molded base material with unevenness made of synthetic resin board or hard fiber board, or a flat base material, and the surface thereof may be coated. Chemical fibers are used as ornamental fabrics,
It consists of a raised fabric such as moquette or carpet with a raised length of 1 to 10 mm woven with natural fibers or other arbitrary fibers, while the synthetic resin skin material may be one that can be high-frequency welded. The material does not matter, but depending on the material, a synthetic resin adhesive layer for high frequency welding such as true melt adhesive may be formed in advance on the back side of the part to be welded. In order to melt away the raised hair in the area where the synthetic resin skin material is to be high-frequency welded or to make it thinner by melting it down or laying it down before applying high-frequency welding treatment, it is necessary to apply pressure using high-frequency waves, ultrasonic waves, or a mold for heating and melting. However, when using fabric ornaments made of materials that are difficult to melt and remove or fall down using these methods, it is necessary to spray a low-melting point real-melt resin powder between the naps of the concerned part and pressurize it with the mold. Moreover, this thinning can be done immediately before coating the synthetic resin skin material or before coating the fabric ornament on the base material (Example) Next, To explain the invention in detail with reference to the drawings, fil is a lower mold for vacuum forming having a concave-convex surface, and an upper mold (2) to be paired with it is installed above it so that the molds can be freely matched. be done. (3) is a base material that is set on the mold surface of the lower mold (1), and the base material (3) is a synthetic resin board or hard fiberboard that has been pre-molded into a textured material. A part of the surface of the base material (3) is coated with an ornamental fabric (4) made by cutting a carpet fabric made of polyamide fiber with a brushed length of about 6 cm into the desired shape, and this is coated with the ornament fabric (4). ) is temporarily attached. For example, as shown in No. 40, the ornament fabric (4) has the inner cavity (6) of the contour-shaped weld tooth (5) of the acid ornament fabric (4) connected to a vacuum source, and the lower end opening is a perforated temporary ( 7) and the weld upper mold (9) closed by the breathable cushioning material (8), vacuum adsorb the ornament fabric (4) to the required position of the base material (3) and connect it to the weld lower mold aI. By applying pressure between them, the raised part of the peripheral edge part was melted and thinned, and air was then blown into the inner cavity (6) to attach it with the adhesive interposed between the ornament fabric (4) and the base material (3). The base material (
3), a thin wall portion (4a) as shown in FIG. 3 is formed by melting and removing the naps on the peripheral edge portion of the surface of 3), but the thin wall portion (4a) is formed by lying down without melting.
In this case, it is preferable to use a synthetic resin adhesive or the like so that the laid down nap is adhered to the surface of the ornamental fabric (4). In this way, when the base material (3) partially covered with the ornamental fabric (4), which has been thinned by melting or removing the naps on the peripheral edge, is placed in the lower mold (11), the vinyl chloride resin is used. A laminated type synthetic resin skin material (11) consisting of a film and a vinyl chloride resin foam is interposed between a lower mold (1) and an upper mold (2) as shown in Fig. 1, and its periphery is chucked. Then, the synthetic resin skin material (11) is completely adsorbed onto the surface of the base material (3) partially covered with the ornamental fabric (4) and bonded by vacuum forming.Then, the base material (3) Remove it from the lower mold (11) and transfer it to the receiving mold (12) for welding and fusing the skin material as shown in Fig. 2.
3) attached to the negative side of the tooth mold (14).
) is lowered, and the overlapping portion of the synthetic resin skin material (11) with the edge portion of the ornamental fabric slit (4) is welded by frequency welding to the thin wall portion (4a) described above using the tooth pattern (14). At the same time, the excess synthetic resin skin material (11) covering the ornamental fabric (4) is removed by fusing using the fusing blade (13), and then the finishing upper mold (1) is removed.
5) is raised to remove the above-mentioned fused and cut excess portion, and the base material (3) is removed from the receiving mold (12) to form a product.

) and the ornamental fabric (4) are high-frequency welded at the thinner part of the ornamental fabric (4) by melting and removing the raised naps or laying it down, so the joining strength is excellent and the appearance is good. It gives a good finish, and since there is no electric field concentrated from the fusing blade to the nap tip during welding work, there is no generation of sparks or whitening phenomena.

。(Effects of the Invention) As is clear from the above description, the present invention provides a method for welding a synthetic resin skin material to an ornament fabric and melting and removing the remaining portion of the synthetic resin skin material. By removing 7 volumes of the raised fluff at the peripheral edge where the skin material is to be welded or by laying it down in advance, we are able to eliminate poor welding and reduce the molten resin caused by sparks caused by electric field concentration at the tip of the raised fluff. It has the advantage of eliminating the whitening phenomenon caused by scattering and falling of the brushed hair around the welded area, resulting in a good-looking finish.
This is a significant contribution to the industry as it solves the problems of the conventional manufacturing method for this type of automobile interior material.
