Abstract

1,003,033. Mould for making cellular articles. DUNLOP RUBBER CO. Ltd. April 24, 1962 [April 24, 1961], No. 15574/61. Heading B5A. A mould comprises one or more pairs of cavities 3, 4 in either two halves of a formed sheet or two solid blocks of thermoplastic, the pairs of cavities being brought together when the sheets or blocks are hinged about a flexible section 8 which may be formed by a groove. Moulds comprising formed sheet may be reinforced by metal or glass fibre-resin backings. In use each half of the mould is filled with foam-forming composition and the mould closed before the composition has set. In Figs. 3, 4 a block 12 of preformed foamed polyurethane is included to make a two density cushion. The mould can be made by vacuum forming polypropylene sheet. Specifications 1,003,031 and 1,003,037 are referred to.
