Abstract
A method of coating flexible sleeving is disclosed generally comprising the steps of passing flexible sleeving from a supply source into a heating unit, heating the flexible sleeving in the heating unit to an outside surface temperature sufficient to aid extrudate bonding but insufficient to damage the flexible sleeving, passing the heated flexible sleeving through a crosshead extrusion die assembly wherein the tip and die have substantially zero land length without the application of deformative forces beyond apparatus friction to the flexible sleeving, extruding a coating of an electrically insulative resinous material onto the flexible sleeving in the crosshead extrusion die, cooling the coated flexible sleeving, and processing the cooled, coated flexible sleeving so as to render it thermally stable at all temperature extremes in which use thereof is contemplated.
