Abstract

Extrusion die with outlets for a radiating series of individual strands, an adjacent alternative outlet for a bulk sheet extrudate of similar width or dia. to the array of strands, and means for alternately interrupting each outlet stream without simultaneously stopping both. Pref. both outlet patterns are annular and flow control is by a pair of reciprocating knives at an interval which allows either of the two die outlets to be uncovered progressively as the other is choked. For mfre. of integral mesh or network extrudates, esp. which the initial extrudate is subsequently stretched longitudinally and radially over a suitable mandrel.
