ABSTRACT:
This application describes a cross-head for directing flowable polymeric materials 90.degree. from the axis of an extruder or similar pressure source and providing substantially uniform pressure patterns at the cross-head output. This is accomplished by dividing and subdividing the stream entering the cross-head, each subdivision taking place on an axis of pressure symmetry and each substream being twisted 90.degree. before reaching its next point of subdivision. The subdivision and twists are accomplished by mounting twisted pieces of flat bar stock in the conduit carrying the stream or substream, each piece having its input end positioned on the axis of symmetry of the stream at the point of stream division.
