Abstract

1458841 Continuous melt thermoforming DU PONT OF CANADA Ltd 25 Feb 1974 [28 Feb 1973] 8504/74 Heading B5A A process for the continuous melt forming of articles of uniform thickness, e.g. pie plates from a thermoplastic polymer, e.g. polyamide. comprises the steps of extruding a flat web 18 downwardly over a series of mould cavities 14 in a wheel or belt to sequentially cover the cavities, and cooling the polymers, the cavities being formed in moulds comprising a porous metal, e.g. bronze or stainless steel. In the figure the wheel is driven by a motor 6 and belt 5, and a segment 8 sequentially connects each mould with a sourse of vacuum 10 via a pipe 9. The formed articles can be cooled by a fan or internal cooling means on the wheel.
