Abstract

721,902. Moulding door panels &c. from thermoplastic sheet material. ARLEY FABRICATIONS, Ltd. March 20, 1953 [March 20, 1952], No. 7161/52. Class 87 (2). A sheet of plastic material 6, which can be softened by heat and stretched while hot is heated and clamped by supports 1 over an opening 2 in a press bed 3 and is then stretched over former 5 by depressing press head 4 which is then left in position until the plastic material has cooled and set. The former 5 is made of material, such as wood, which is a bad conductor of heat. When it is required to make a depression in the sheet, a former 7 is placed in the opening 2, over which the sheet is stretched to make the depression, such for instance as a housing for a handle in a door.
