Abstract

1470498 Sheet forming dies K KICHLU 27 March 1974 [28 Dec 1972] 35492/72 Heading B5A A sheet forming die, e.g. 1 or 2 comprises one or more facing silicon rubber units, e.g. 5 or 6 removably attached to a rigid heated backing, e.g. 1a or 2a. The facing unit(s) may be provided on one or both dies of a matching pair 1, 2, on a ball or roller (13, Fig. 2, not shown) co-operating with a die (9) or on a vacuum male die (32, Fig. 3, not shown) co-operating with a flexible fluorocarbon shaping diaphragm (40). The facing units may be provided with flexible cover sheets 7, 8, may be embossed and/or provided with printing matter, e.g. transfers, may incorporate powdered glass filler and may be subject to change of size by application of internal pressure. The cover sheets 7, 8 may comprise the electrodes for radio frequency heating of the dies. The sheet being formed may comprise a non-woven fabric or felt either composed of or containing thermoplastic fibres or a thermoplastic binder, a mat or felt impregnated with a hardenable resin or a thermoplastics sheet, e.g. polyurethane. The sheets may contain glass or sisal fibres or felt reinforcement. The formed sheet may be provided with a polished, brushed, matt or showerproof surface. The sheets may be used for producing shoes, hats and gloves.
