Patent ID: 8235696

Claim:
An in-mold forming apparatus, comprising: an injection molding unit comprising a first mold and a second mold for injection molding; a film feeding mechanism for feeding in-mold foil between said first mold and said second mold; a transfer foil being formed on said in-mold foil; a mold closing mechanism for closing said first mold and said second mold, thereby to fix said in-mold foil inside a cavity formed between said first mold and said second mold; a resin injection forming mechanism for injecting fused resin into said cavity, thereby to unite said transfer foil formed on said in-mold foil with said resin; and a charger arranged in the neighborhood of at least one of said first mold, said second mold, and said in-mold foil; said charger including a charging unit for freeing ions by applying to a charging element capable of charging particles in the neighborhood of said in-mold foil upon application of a sufficiently high voltage, said charger configured to apply said sufficiently high voltage to said charging element to charge particles in the neighborhood of said in-mold foil, and a plate electrode having a front surface and a rear face, said rear face being charged positively for adsorbing said particles charged by said ions; wherein said particles are foil dusts separated from said in-mold foil, said charging unit and said plate electrode are arranged opposite to each other across said in-mold foil, and said plate electrode includes an insulator arranged on to cover said front surface of said electrode opposite to said charging unit, and wherein said charging unit faces one surface of said in-mold foil, said insulator has a first surface facing an opposite surface of said in-mold foil and a second surface opposite said first surface facing said front face of said plate electrode.
