摘要：<p>An extrudate rotator die element, (24) extrusion die (18) comprising the extrudate rotator die element and a method for making multiple stripe extrudate from multilayer extrudate. The extrudate rotator die element (24) comprises a plurality of inlet slots (46), a plurality of outlet slots connected by rotated slot cavities (44). Each slot cavity (44) has a major cavity axis that rotates such that the outlet major axis of each outlet slot is oriented at an angle from the inlet major axis of the connected inlet slot (46) and the outlet slots are oriented such that each outlet major axis is coplanar with each other outlet major axis.</p>
