Abstract

An apparatus and a method for forming a sheath over an elongate member comprises an extruder that has an output to supply a melt material having a temperature. A heat exchanger connected downstream the output of the extruder removes heat from the melt material in a controlled manner. An elongate member, which may be a cable core, is supplied to a crosshead that is connected downstream the heat exchanger to surround the elongate member with a sheath of the melt material.
