Abstract

Extruder head incorporates an eccentric toothed disc or collar coincident with an annular extrusion die to produce perforated tubing or netting. A toothed element bears against a solid collar or core respectively where the teeth intersect the flow path. The nip ensures that the melt path is perforated and the melt is unable to deform over the end of the tooth and thus produce blind interstices. The core plate or collar may have a smooth or ribbed annular profile to butt or mesh with the cutter teeth.
