Abstract

998,085. Moulding hollow articles from thermoplastic material. JOHN WADDING- TON Ltd. Sept. 8, 1961 [June 9, 1960], No. 30006/60 Divided out of 993,054. Heading B5A. A sheet of thermoplastic material, e.g. polythene, polyvinyl chloride, polycarbonate or cellulose acetate, at moulding temperature is folded longitudinally and fed to a divisible mould which is clamped against the sheet, and the sheet moulded by blowing or by vacuum. The mould is cooled by air or water, and may have holes for escape of air. The mould may move with the sheet and several moulds may be used for simultaneous moulding operations. Specification 875,819 also is referred to.
