Abstract: Apparatus for loading and unloading a frame bearing a cover material for application to a formed thermoplastic sheet, especially in the production of cover panels for motor vehicles, is associated with a press including two dies for simultaneous moulding of the sheet and application of the cover material thereto, and includes a take-up station disposed outside the press for taking up a frame and a device for automatically transferring the frame from the take-up station to a moulding station between the dies. The device includes a pair of guides supported by one of the dies, the guides extending from the take-up station to the moulding station. The device further includes a frame take-up member mounted for sliding movement along the guides and associated with an actuator for controlling movement of the frame take-up member between the take-up and moulding stations.
