Abstract:
An apparatus for forming a pattern onto an article during an injection molding thereof, comprising:means for feeding a pattern-bearing film in a film feeding direction to a molding position where a male mold and a female mold are opposed, said male and female molds having parting surfaces, respectively;a heating board for heating said pattern-bearing film so as to soften the film, said heating board having a heating surface and being movable into and away from a space between said male mold and said female mold;means for transferring said pattern-bearing film to an internal surface of said female mold so as to cause said pattern-bearing film to contact said internal surface;means for causing said male mold and said female mold holding said pattern-bearing film in the female mold to approach each other to form a closed molding cavity;resin injecting means for injecting a molten resin into said cavity to form a molded article to adhere said pattern-bearing film to a surface of said article; anda heating wire supported on an upstream-side surface of said heating board with respect to said film feeding direction and at an upstream side of the female mold with respect to said film feeding direction, said heating wire being operative to heat the pattern-bearing film so as to cut the film into a proceeding portion and a following portion thereof when the heating board is moved to the pattern bearing film that has been transferred onto the parting surface of the female mold.
