Abstract
A die for extrusion of an extrudate from an extruder has a tubular member, a hollowed distributor portion and a hollowed nozzle portion configured and arranged so that extrudate issuing from the die has two visible longitudinal components. The tubular member has three successive and integral portions wherein first and third portions are, in cross-section, continuous and wherein the second portion is, in cross-section, discontinuous. The first tubular member portion has an interior wall surface which, in cross-section, has radial projections and recesses therebetween so that the interior wall surface defines a shape which is an outline of a star-like shape, and the second tubular member portion has longitudinal openings which are in alignment with the first portion projections. The distributor portion surrounds the first tubular member portion to define a chamber and has an opening into the chamber, and the nozzle portion has a first end integral with the distributor portion and extends to the third tubular member portion to define a chamber extension and end enclosure.
