发明名称 Process and system for bending of a cellular sheet
摘要 A process and a system is employed for bending to a curved contour a light-weight cellular plate (10), wherein three plate layers (11-13) are connected to each other in pairs via layers of glue. The cellular plate (10) has a first, planar outer layer (11) and a second, opposite, planar outer layer (12) together with a third, intermediate layer (13) of cellular material. A pressure plate (14) and a counter pressure plate (15) receive between them the cellular plate (10) and these plates (10, 14, 15) are arranged on a moulding means (16), after which the plates (10, 14, 15) are jointly clamped against the moulding means in a stationary fastening region. After this the plates are jointly pressed in regions laterally outside the stationary fastening region against the moulding means. Pressure loading (C) is exerted successively in a lateral direction from the stationary fastening region in a direction towards the edge region of the plates (10, 14, 15).
