Abstract

Apparatus for forming an insulation layer around an electrical conductor comprising an extruder head and a die insert within the head, the insert having a feedpath for the conductor towards the die orifice. An insert holder is provided and the insert is pivotally movable within the insert by the use of a flexible mounting means which allows for movement of the insert about any plane. The mounting means may be a flange with an annular weakened section to provide the flexibility. Alternatively, the mounting means comprises spring steel annular tubes disposed between the insert and holder.
