られていた。 However, in this method, when the base resin is injected into the cavity, the resin flows while contacting the skin material, so the skin material partially expands and contracts due to the flow resistance of the resin, which causes molding. Wrinkles and flow patterns remain on the surface of the product, resulting in defects in appearance. In order to solve this problem, it is necessary for the skin material to be placed along the mold surface, but conventionally, for example, a weight was hung from the bottom edge of the skin material so that tension was applied to the skin material when the mold was closed. A similar device was used.

材が得られた。Embodiment 1 FIG. 1 shows an embodiment of a device for supplying a skin material to a mold according to the present invention. The part of the skin material 3 that is unwound from the roll 1 and wound onto the winding shaft of the roll 2 that passes between the male molding die 4 and the female molding die 5 is connected to the male molding die 4. Close the mold while pressing. At this time, the skin material 3 on the roll 2 side is clamped and fixed by the clamp 6 to prevent the roll 2 from rotating in the opposite direction. When the skin material 3 is pressed against the female mold 5 using the male mold 4, the skin material 3 is first pressed against one end surface of the male mold 4 by the pressing roller 7 and fixed roller 8. When the mold is further closed, tension is applied to the skin material 3, and the skin material 3 is disposed along the mold surfaces of the male molding die 4 and the female molding die 5. For the pressing roller 7 and the fixed roller 8, one pair having a roller portion having a length suitable for the width of the skin material 3 may be used, or two or more pairs having a roller portion having a short length may be used. Further, the length of the handle of the pressure roller 7 can be adjusted in the mold closing direction using a resilient means such as a spring, as shown in FIG. 2 (a perspective view of the handle surrounded by a broken line in FIG. 1). It is designed to be expandable and contractible (the pressing roller 7 is movable in the mold closing direction) so that appropriate tension is applied to the skin material 3. Also, the roll 1 is configured to rotate when the skin material 3 is pulled with a force greater than a predetermined tension, or the tension applied to the skin material 3 is detected by a tension meter, and this value matches the set value. It may also be configured to rotate automatically. After applying a certain tension through the above operation, a base resin such as polypropylene was injected into the cavity to form an automobile ceiling material, and a ceiling material with a desirable skin appearance without wrinkles or flow patterns on the surface was obtained. It was done.

Conventionally, the upper end of the skin material 3 was clamped by a clamp 6 equipped with a spring 12, and then the weight 13 was suspended from the lower end of the skin material 3 and the mold was closed while applying tension, so the weight 13 did not need to be attached or removed each time molding was performed. In addition, the molding process becomes very complicated, such as using different weights 13 depending on the type of skin material 3, etc.
Furthermore, the molding efficiency was also poor.
