Abstract

1,083,034. Vacuum moulding. DUNLOP CO. Ltd. May 27, 1964 [June 13, 1963], No. 23508/63. Heading B5A. A male or female moulding member, for use in a vacuum forming process, has at least part of its forming surface made of a resilient material, e.g. foamed or unfoamed synthetic or natural rubber, so as to enable it to be easily withdrawn from any undercut portion of the formed article. In Fig. 1 (not shown) a sheet of polypropylene is drawn to the shape of a wheel over a vacuum mould (1), a lip (8) being formed by a ring (9) of non-cellular vulcanized rubber. In a second embodiment, shown in the Figure, a female vacuum mould, comprising a ring 28 and a shaped central disc 29 seated in a flanged backing member 23, is used to form a wheel from a sheet 35 of polypropylene. The mould cooperates with a male plunger comprising a backing member 21, to which is bonded a ring 22 of foamed rubber having a lip 23, which lip forms the undercut portion 33 in the finished article.
