Abstract

997,212. Striped extrusion. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 24, 1963 [Dec. 31, 1962], No. 49137/62. Heading B5A. In a method of producing striped thermoplastic extrudates, coloured material in a chamber e in the die system is extruded through the same orifice F as the mainstream of thermoplastic, part of the mainstream being diverted through ducts d to exert pressure on the coloured material causing it to extrude through ports p to joint the mainstream at F and form stripes thereon. The chamber is formed as a U-shaped well in the die ring M having a cover C and may be divided into compartments to hold materials of different colours. A floating disc BS may be interposed between the coloured material and source of pressure. The mandrel and/or die ring may be rotated so that the stripes form a pattern and the extruded tube may be subjected to a blow operation. In another embodiment, the chamber e is formed in the mandrel. The method may be applied to the extrusion of rods, sheets, tubes, coating wires &c.
