    Abstract: In the method, after the pattern-bearing film is fed to the female mold, the distal end of the film is fixed under a lower portion of the female mold, and at the same time the film is retreated by a force from the film supply portion. Thus, this tightens up the film so that the slacks or wrinkles cannot be formed on the film. Therefore, the film can be fortunately spread around the parting surface of the female mold. In the apparatus, the film suppressing frame is pressed to the female mold through the sliding rod arranged in the female mold, in such a manner that the female mold embraces the frame. Thus, the pressing of the frame is performed by a simple structure, and the film is accurately positioned to the internal surface of the female mold. Also, the film suppressing frame is constituted to advance from and retreat to the female mold. Thus, this causes a space between the both molds and an outside standby position to be useless. A space around the apparatus can be effectively utilized.

    Abstract: A pattern-bearing sheet for a simultaneous injection-molding and pattern-forming method, has a sufficient malleability in the following conditions. When the sheet is cut to a 10-mm width and subjected to a tensile load and thus elongated at a rate of 30%/second in an environment at 50.degree. C., the sheet should exhibit a stress value of 0.6 kg or higher at the yield point and after passing through the yield point in the case where the sheet is formed from a material having a yield point, and the sheet should exhibit a stress value of 0.6 kg or higher at an elongation of 10% and higher in the case where the sheet is formed from a material not having a yield point. Desirably, the value when the sheet cut to 10-mm width is elongated at a rate of 7%/second to an elongation of 200% (200% modulus value) at a temperature of 100.degree. C. to 120.degree. C. should be 0.3 kg or lower.

    Abstract: A decoration sheet is retained on the cavity periphery by a sheet clamp in such a state that it is projected into a molding cavity of a female die. Then the decoration sheet is heated and softened by a curved hot platen, and thereafter it is drawn through suction ports of the female die to bring the sheet into close fit to the inner periphery of the molding cavity. The deformation amount of the decoration sheet heated and softened is decreased in premolding the sheet into the molding cavity surface of the female die. Therefore, distortion of the decoration sheet, appearance of wrinkles, and breakage thereof become little. Next, the female die and the male die are coupled with each other to effect die clamping, and a molten resin is poured to fill the molding cavity to effect injection molding.
