发明名称 FORMING METHOD OF THERMOPLASTIC RESIN SHEET
摘要 PURPOSE:To obtain a formed article, the sheet stocks of which are different from each other locally, by a method wherein thermoplastic resin sheets, at least one of which is made so as to have the width narrower than the width of hot glued laminated sheet, are employed so as to hot glue two or more sheets under the condition that one of their side edges is put upon the other. CONSTITUTION:Two different sheets S and H are fed parallel to a forming device by passing through a guide 20 arranged to a trestle. Both the respective widths W1 and W2 of tire sheets S and H are made to be narrower than the width W of the hot glued sheet. The forming device carries both the sheets S and H under the condition that only both their sides are clamped to a heating section 50 and a forming section. The central part of the sheets are locally hot glued with a heat sealer 42 so as to be made into an integral body and carried. After that, the laminated sheet is pressed with hot plates 52 and 52' and formed with molds 52 and 62'. When a container is formed at a forming section 60, the container main body side is made of the sheet S and the cover side is made of the sheet H. Thus, laminated sheet, the necessary portion of which can show proper function, can be obtained.
