しておいてもよい。(Example) Next, the present invention will be described in detail using an example in which a door trim for an automobile having the shape shown in FIG. 3 is manufactured. The material is made of synthetic resin, hard fiberboard, hardboard, etc., and a skin material 3 having at least the surface thereof, such as a fabric skin material or a bonded skin material, is adhered to the surface thereof, First of all,
A preset mold 4 having a mold surface corresponding to the surface shape of the molding base material 1 is manufactured from an iron plate. The preset mold 4 is provided with a large number of suction holes 5 as shown in the figure, and the inner cavity 6 is connected to a large capacity vacuum source such as the suction side of a blower through a suction pipe 7. Then, on the surface of this preset mold 4, as shown in FIG.
The cloth surface is placed facing the preset mold 4 without clamping the periphery of the skin material 3, and the surface material 3 is sucked onto the surface of the preset mold 4 by suction pressure applied through the suction hole 5, so that the periphery becomes free. To make a skin material 3 in close contact with each other without plastically deforming it. At this time, since the skin material 3 is only lightly fixed to the surface of the preset mold 4 by suction, it is in a state where misalignment and wrinkles can be corrected very easily by hand. Next, the second
As shown in the figure, a molded base material 1 whose surface has been spray-coated with a two-component adhesive is suctioned and brought into close contact with the surface of the preset mold 4, and is shaped into a shape corresponding to the surface shape of the molded base material 1. When pressed against the back side of the skin material 3, the skin material 3 is adhered to the surface of the molded base material 1 without wrinkles, so its outer periphery is wrapped around the back surface of the molded base material 1 and secured with a tack needle or the like. Then, an automobile door trim as shown in FIG. 3 is obtained. As the skin material 3, any material can be used, such as a single fabric skin material, a bonded skin material backed with urethane foam, or a raised skin material with a raised surface. For 1, materials molded from non-porous materials such as hardboard, synthetic resin molded products, hard fiberboard, and iron plates can be used, and any type of adhesive can be used. Moreover, in addition to being applied only to the surface of the molded base material 1 as in the above embodiment, it may also be applied to the back surface of the skin material 3.

る。(Effects of the Invention) As is clear from the above description, the present invention allows a skin material having at least a cloth surface to be easily attached to the surface of a molded base material having a complex surface shape without causing wrinkles. This material can be used as an interior material for automobiles.
If the slope of the uneven portion is within a range of about 60°, the skin material can be adhered without difficulty, and the present invention is not limited by the material of the molding base material, and the skin material can also be applied to at least the surface. As long as it has a cloth surface, there is no need to use expensive materials with good moldability, and even unskilled workers can mass-produce products of uniform quality. This is an extremely significant contribution to the industry as it solves manufacturing problems.
