Abstract
Apparatus for forming an insulation layer around an electrical conductor and having a die insert or core tube for guiding the conductor through a die orifice. The insert is movable to control its position and its position is controlled by two rotatable mountings. A first of the mountings eccentrically holds and is rotatable around the insert while the second mounting lies radially outside of and eccentrically holds the first mounting. A monitoring means analyzes degree of eccentricity of the conductor and operates a driving means for the mountings to move the insert in the appropriate direction for concentricity.
