Abstract
Abstract An extruded integral plastics net structure comprising first sets of spaced parallel strands, second sets of spaced parallel strands extending transversely thereto, the sets of strands being joined together at all or certain of their points of intersection to form a net structure wherein the intersection points along any one strand are in the alternating forms of any two of the following: (a) integral masses of mirror image symmetry about the median plane of the net, (b) assymetrical junctions in which there is substantially only linear contact and adhesion between the strands and (c) symmetrical junctions having only linear contact with little or no adhesion between the strands.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
144 words
An extruded integral plastics net structure having mesh members comprising a first set of spaced parallel strands and a second set of spaced parallel strands extending transversely thereto, each set of strands comprising strands of dissimilar cross section, the sets of strands being joined together at at least some of their points of crossing to form a net structure wherein the crossing points along any one strand of the first set comprise (a) integral junction masses of mirror image symmetry about the median plane of the net intersections, and (b) asymmetrical junctions in which there is substantially only linear contact and adhesion between the strands and the crossing points along any of the strands of the second set comprise the latter form (b) and (c) symmetrical junctions having only linear contact and adhesion between the strands at crossings with no adhesion between the strands.
Claim 2
Dependent Claim
144 words
An extruded integral plastics net structure having mesh members comprising a first set of spaced parallel strands and a second set of spaced parallel strands extending transversely thereto, each set of strands comprising strands of dissimilar cross section, the sets of strands being joined together at at least some of their points of crossing to form a net structure wherein the crossing points along any one strand of the first set comprise (a) integral junction masses of mirror image symmetry about the median plane of the net intersections, and (b) asymmetrical junctions in which there is substantially only linear contact and adhesion between the strands and the crossing points along any of the strands of the second set comprise the latter form (b) and (c) symmetrical junctions having only linear contact and adhesion between the strands at crossings with no adhesion between the strands.
Claim 3
Dependent Claim
54 words
An extruded integral plastics net structure as claimed in claim 1, wherein each mesh member is a dual strand comprising two strands so that each mesh member crossing comprises four intersection points one of form (a), two of form (b) and one of form (c), forms (a) and (c) being diagonally opposite each other.
