发明名称 APPARATUS FOR PRODUCING OPENINGS OR PRE-OPENINGS ON AN ARTICLE SHAPED BY THERMOFORMING IN A SET OF PRESSURE-CASHING DIE/COUNTERDIE
摘要 A device for making cutouts or precut scores in thermoformed parts within the mould/counter-mould assembly consists of a counter-mould (4) arranged to internally house a support (5) for cutting block (6) able, during certain production phases to form score lines or cut-outs in the material (2). The support (5) is mounted on a hinged structure (7) which can be moved vertically up or down with the aid of a pusher shaped cam (8) associated with a control means (9). The cutting block assures the formation of the cut lines during closing of the mould and the formation of the thermoformed part.
