Patent ID: 7261532

Claim:
An in-mold decoration apparatus comprising: a fixed mold half; a movable mold half provided in opposition to said fixed mold half and movable in such a direction as to separate from and contact with said fixed mold half; a first decorating sheet feeding machine comprising an upstream-side frame provided on a first side of one mold half of said fixed mold half and said movable mold half, a downstream-side frame provided on a second side of said one mold half at a position opposed to said upstream-side frame in a horizontal direction such that said one mold half is disposed between said upstream-side frame and said downstream-side frame, a first feed roller provided on said upstream-side frame, for feeding a first decorating sheet in the horizontal direction, a first take-up roller provided on said downstream-side frame, for taking up the first decorating sheet fed from said first feed roller, an upstream-side sheet guide roller provided on said upstream-side frame so as to be movable in a vertical direction with respect to said upstream-side frame, for guiding and supporting the first decorating sheet fed from the first feed roller; a downstream-side sheet guide roller provided on said downstream-side frame so as to be movable in the vertical direction with respect to said downstream-side frame, for supporting the first decorating sheet taken up on the first take-up roller, an upstream-side guide roller moving part provided on said upstream-side frame, for moving said upstream-side sheet guide roller in the vertical direction with respect to said upstream-side frame, a downstream-side guide roller moving part provided on said upstream-side frame, for moving said downstream-side sheet guide roller in the vertical direction with respect to said downstream-side frame, and a control section for performing alignment of the first decorating sheet with said one mold half by controlling said first and second guide roller moving parts to move the first decorating sheet in the vertical direction; and a second decorating sheet feeding machine comprising a second feed roller provided on a first side of the other mold half of said fixed mold half and said movable mold half, for feeding a second decorating sheet in the vertical direction, and a second take-up roller provided on a second side of said other mold half at a position opposed to said second feed roller in the vertical direction such that said other mold half is disposed between said second feed roller and said second take-up roller, for taking up the second decorating sheet fed from said second feed roller; wherein, with the first and second decorating sheets pinched between said fixed mold half and said movable mold half, molten resin can be injected into said fixed mold half and said movable mold half so that patterns of the first and second decorating sheets are respectively bonded to surfaces of a resin molded article.
