Abstract

474,001. Shaping thermoplastic resins. TRIPLEX SAFETY GLASS CO., Ltd., CHART, A. D. D., and BAKER, H. W. June 25, 1936, Nos. 17707 and 21607. [Class 87 (ii)] A shaped article is made from a sheet of thermoplastic resin, by holding the sheet in a continuous ring-shaped clamp, heating the sheet until it becomes plastic, and maintaining a difference of fluid pressure between the opposite faces of the sheet until the sheet has been sufficiently distended. When the sheet has cooled, the pressure is removed, and the article is removed from the clamp. The clamped portion may be cut off or it may remain as part of the article. Liquid or gas or both, or vacuum may be employed for producing the pressure difference. As shown, a sheet of thermoplastic resin such as is described in Specifications 417,999, 419,357. and 421,397, [all in Group IV], is clamped between a ring 11 and a disc 14 having an inlet 15 for compressed air. The sheet may be blown upwardly, as shown, or downwardly or horizontally. The sheet may be made of superposed parts to prevent thinner portions 18 from being produced. The invention is applicable to the shaping of windscreens for aircraft.
