Abstract

Extrusion of crosslinked mesh or netting using a die which can extrude continuous tubular film and which also deposits transverse hoops or strips on to the extruded tubing, has knives for cutting the tubing into longitudinal strands, associated mandrel and haul off equipment for biaxially stretching the resulting mesh. The knives may slit the tubular layer before or after the deposn. of the transverse strips.
