Abstract

There is provided sheet forming apparatus comprising a supporting frame (10) having pivotally mounted thereto a mandrel member (13). The supporting frame (10) slidingly mounts a flexible sheet metal platen (17) secured to the mandrel member (13) by a sheet engagement clamp assembly (20) including an air manifold (18) adapted to blow air into the cores of a clamped core sheet. The mandrel member (13) is operable by pneumatic ram assembly (24). A heater assembly (27) heats the underside of the platen (17). A trailing edge sheet clamp assembly (32) locates a sheet to be formed under tensile control of a pneumatic ram assembly (33). A heater hood (35) is adapted to heat the upper surface of a sheet to be formed on the platen. Control of the working components is centralized in a control assembly (not shown) comprising a programmable logic controller electronically controlling heating and exercising electropneumatic control over the respective sheet clamps and rams.
