A strip-like pattern sheet has a plurality of patterns and register marks spaced apart from each other by a predetermined distance in its longitudinal direction. The pattern sheet is transported from a supply roll to a take-up roll in such a way that it covers the opening of a female mold. At the upper stream of the female mold, the register marks are detected so that a pattern-sheet-holding-and-transferring means holds the pattern sheet at a predetermined position and heats it. The pattern sheet is displaced by one pitch so as to cover the opening of the female mold. The softened pattern sheet is pressed by a compressed air against the cavity surface of the female mold with the cavity being evacuated. Thereafter the holding-and-transferring means is returned to its initial position and the female and male molds are mated so that molten resin is injected into the molding cavity defined between the female and male molds so that a pattern is imprinted on the surface of a molded article or finished product. The pattern may be imprinted or transferred in an efficient manner and the precise registration between the pattern and the surface of the molded article or finished product can be attained.
A device for molding an article by injection molding while simultaneously imprinting on or transferring onto the molded article each pattern which is printed on a continuous sheet in a predetermined pitch, wherein the pattern sheet is pressed under the air pressure against the cavity surface of a female mold prior to the injection molding, and molten plastic material is injected from a male mold into the cavity defined by said male and female molds which are mated together, whereby said pattern sheet and the molded article are integrated with each other, said device comprising:
A device as set forth in claim 5, wherein said shift means has a supporting plate connected to one end of the transfer means and a moving plate movable in one direction with respect to the supporting plate, said cover means being capable of moving on the moving plate in the direction perpendicular to the above direction with respect to the supporting plate.
