Abstract:
An apparatus for shaping thermoplastic materials, comprisinga suction-pressure bell; an upper clamping frame and a lower clamping frame between which the material to be shaped can be clamped, each said clamping frame having an opening surrounded by a rim which is received against said material during shaping; a seal between the suction-pressure bell and the upper clamping frame, which seal can be expanded under controllable force so that said material can be drawn into said suction-pressure bell during shaping; a mold which can be received through said openings against said material during shaping; a lower part supporting the mold and the lower clamping ring; and a force absorbing device which can connect the suction-pressure bell and lower part supporting the mold, which device absorbs forces occurring during shaping.
