Abstract

The invention relates to an extrusion head for producing hose- or pipe-shaped preforms from extrudable plastics, which preforms are preferably composed of several layers. The extrusion head comprises a plurality of distributors which are combined to form units and which each consist of four distributor discs 29 to 32 contacting one another by means of contact faces 33 to 38, with the contact faces constituting planes on which the longitudinal axis 26 is positioned perpendicularly. In the region of the contact faces of the distributor discs 29 to 32 there is arranged a feeding channel with two passages which provide connections with two partial channels 43, 44 which are also arranged between the distributor discs 29 to 32 or the separating planes therebetween and which each end in one portion in the plane in which the central distributor discs 31, 32 contact one another and form the annular exit gap 53. In this way it is possible to achieve a modular system and an assembly which is
