Abstract

Press head for an extruder to supply a conductor 60 with a covering sheath 62 with two layers, comprising two distributors mounted in a body 1 with distribution channels for two different-colored plastics. To supply the conductors in alternation with a covering sheath of one or the other color or with a striped covering sheath without stopping the production line and without removing the press head each of the distribution channels of the distributor is divided into different zones and feed channels 11, 11', 12, 12' are arranged in the body, which controlled by throwing valves 51, 51' feed the distribution channel zones diametrically opposite with different colored plastics in alternation so that the color in the surface and inner layer 62a, 62b of the covering sheath can be thrown into diametrically opposite zones of the covering sheath and in relation to the layers in the adjacent zones. <IMAGE>
