For the production of netting from thermoplastics, the material is first melted in the extruder and subsequently extruded through counter-rotating nozzles which have holes on the circumference. The extruded melt strands from the inner and outer holes fuse to each other at the points where they cross. This way an endless netting tube is made which is then cooled, folded flat, cut at the edges (if required) and wound up.
