Abstract

Improvements introduced in the main patent object 388,337, applied on February 16, 1971, for: "An apparatus for extruding a coating on a core of an advancing electrical conductor", whose improvements include an extrusion machine having a hole annular extrusion defined by an outer die and an inner die or tip and having between the inner and outer dies at least one die or intermediate die, the die in position immediately to the inner die having a passage that opens to a space to be delimited between the first extruded layer and the second extruded layer.
