Abstract

896,549. Extruding two-colour articles. TELECOMMUNICATIONS S.A. DE. Jan. 2, 1961 [Jan. 14, 1960], No. 47/61. Class 87(2). [Also in Group XXXVI] In a method of producing a longitudinally extending article by extrusion from an extrusion head, a first quantity of plastic material is transported to the head through a main extruding device 3, and simultaneously a second quantity of plastic material is transported to the head through an auxiliary extruding device to impart a particular characteristic means of identification to the first quantity of material, the auxiliary extruding device having a control means allowing rapid change in the relationship between at least a part thereof and the head, whereby the identification characteristic may be changed without interruption in the production of the extruded article. In Fig. 2 a wire is being coated with plastic material containing two tracer filaments of plastic material of different colours. The auxiliary extruding device is mounted on a rotatable table 31 containing four identical auxiliary extruders, which may be fed each with a differently coloured plastic material from hoppers through feed holes as at 36. Thus rotation of the table 31 to the correct position enables the tracer filaments to be made of any of the four colours, the changes from colour to colour being made without stopping the machine. When at the correct position the auxiliary screw is driven through a dog clutch 34 by a variable speed motor so that the width of the extruded filaments may be varied. The screw casing 30 has a certain play in its longitudinal axis so that, during extrusion, it is forced against the extruder head 38. The head 38 is slidable in a direction at right angles to the plane of Fig. 2, between fixed positions to enable one, two, or more filaments to be extruded on to the wire covering. The head 38 is operated by a doublyacting air cylinder and a pushrod which has a shoulder engaging with different positions on a rotatable cam, Fig. 1 (not shown). Specification 722,591 is referred to.
