ABSTRACT:
A mesh structure comprises intersecting elongate members with each node at which they intersect being on the boundaries of four apertures in the mesh structure. One of said members has a locus which first defines the boundary between a first of said apertures and a second of said apertures, then transits said node and defines the boundary between a third of said apertures and the fourth of said apertures. The other of said members has a locus which first defines the boundary between said second and said third apertures, then transits said node and defines the boundary between said fourth and said first apertures. Said loci or said one member and said other member while transiting said node have such configurations that said members are knotted together. A method of manufacture comprises forming a system of loops in each of a plurality of warp members, inserting a weft member through each of said loop systems consecutively, and drawing tight said warp members so that said loop systems are tightened around the weft member. The configurations of said systems of loops are such that after tightening thereof each said warp member becomes knotted to the weft member. Apparatus operates to perform the foregoing method and thereby manufacture the mesh structure.
