Abstract

1410691 Sheet forming ADOLF ILLIG MASCHINENBAU 29 Aug 1973 [9 Sept 1972] 40674/73 Heading B5A A method of forming articles from thermoplastic material comprises feeding a web 9 through a heating zone A in which the web is heated to below its deformation temperature and the web is supported by a feeding device which offers no constraint to expansion of the web, and then through a heating zone B in which the web is heated to at least its deformation temperature and the edge portions are entrained by the feeding means, e.g. a spiked chain (14), Fig. 4 (not shown), and then to a deformation station (7), Fig. 1 (not shown). The chains can diverge to stretch the sheet in the station B.
