The assembly to shape two thermoplastic boards/films by deep drawing, to be welded together, has transport units which give them the same movement path with compensation for thermal expansion and space savings

摘要

To shape two boards or film webs of thermoplastic materials, and then weld them together, a transport system has two transport units at the deep drawing shaping station and two transport units at the heating station. The stacking magazine(s) is (are) to one side and across the direction of the movement of the boards or film web sections, close to the heating station. To shape two boards or film webs of thermoplastic materials, and then weld them together, a transport system (3) has two transport units (20,21) at the deep drawing shaping station (1) and two transport units (22,23) at the heating station (2). The stacking magazine(s) (4,5) is (are) to one side and across the direction of the movement of the boards or film web sections (19), close to the heating station. At least one transport unit (22,23) can slide across the direction of travel, between the heating station and the stacking magazine(s).
