Abstract

897,384. Vacuum-moulding thermoplastic sheets. HYDRO-CHEMIE A. G. July 8, 1958 [July 9, 1957], No. 21849/58. Class 87(2). [Also in Group XXVIII]. A sheet of resin foil 3 to be moulded into dish form is held on the rim 2 of a vacuum mould box 1 by a frame 4 hinged thereto and after heating is predrawn on downward movement of a compressed air actuated jack plug 10 (see Group XXVIII), to the position shown in dotted lines 11 within the mould 5 which is then evacuated through a duct 9 resulting in the sheet 3 being sucked from the plug and drawn against the mould wall from which it is removed after cooling and withdrawal of the plug by swinging the frame 4 about its pivot.
