Abstract

870,016. Vacuum-forming plastic sheet materials. PARNALL & SONS Ltd. March 29, 1960 [April 9, 1959], No. 11926/59. Class 87(2). A sheet 9 to be vacuum-moulded in a mould 10 is heated by a platen 3 which is swung into a vertical inoperative position (shown dotted) during which movement it is simultaneously rotated by a chain 11 into a position in which the heating surface 3a is directed away from the mould.
