Abstract

Plastics sheets having film thicknesses between 0.05 and 2.5 mm have a fluid pressure medium applied to them at a temperature below plastics softening temperature and are isostatically formed under a medium pressure which is higher than 20 bar. An automatically working apparatus developed for this purpose comprises at least:
- a continuous string (6) of shiftable, frame-like pallets (5) which are advanced by a conveyor (11') step by step;
- a loading station (20) in which one sheet to be formed (3) each is placed on one of the pallets (5) in defined arrangement;
- a heating station (40) in which each sheet (3) is heated to a defined temperature;
- a forming station (50) with a forming tool (51) disposed in a press (70) the drive (100) of which is capable of producing a considerable mould closing force; and - an unloading station (160) in which the formed sheet (5) is removed from its pallet (5) and directed into a collecting device (163).
