Beschreibung
Zusammenfassung:	The present invention is directed to the manufacture of plastic net formed by extruding a plurality of spaced strands of plastic into a net structure. In accordance with the invention, adjacent strands in the net are joined in physical contact throughout all or a substantial portion of the length of the strand between the joints in the net structure. The strands are merged and integrally consolidated in the joints so that in effect the extruded structure is a solid sheet with or without perforations between the strands. Thereafter the strands are stretched preferably in two different directions to draw the strands apart and separate them throughout the length of the strands between the joints to form a high strand count oriented net produced for the first time by extrusion.
