Patent ID: 8192189

Claim:
An arrangement in connection with extrusion tools, which comprises a nozzle structure which is provided with coaxially arranged nozzle elements and coaxially arranged melt channels between the nozzle elements, said nozzle elements and melt channels being arranged to form one or more layers which cover a flexible elongated element on the surface of the flexible elongated element, which passes through the innermost nozzle element, and a guide member corresponding to the diameter of the elongated element for controlling the flexible elongated element, the guide member being a separate unit arranged to be pushed in the direction of the elongated element into its position at least partly inside the two innermost nozzle elements defining a first melt channel, wherein the guide member is arranged to provide a tapered space between the elongated element and the guide member, and that the tapered space is in fluid communication with the first melt channel for extruding a material onto the elongated element through the tapered space in the manner of a pressure tooling.
