Abstract

An extruder die for plastics material has a predetermined cross-sectional area and can be deformed to change this cross-sectional area to allow variation of the cross-section of the extrusion. This finds particular application in the re-covering of a spliced plastics covered rope where the diameter of the rope increases between an uncovered spliced section and the covered remainder of the rope. Such a die can be used to extrude a plastics covering over the splice section and, at the end of the uncovered section, expand over the existing cover to provide a continuously covered rope.
