Abstract: A net structure includes a plurality of metal rightwards inclined wires including, in sequence, a first rightwards inclined wire, a second rightwards inclined wire, and an N-th rightwards inclined wire. The net structure further includes a plurality of metal leftwards inclined wires including, in sequence, a first leftwards inclined wire, a second leftwards inclined wire, and an N-th leftwards inclined wire. The first rightwards inclined wires intersects, in sequence, from the first rightwards inclined wire through the N-th rightwards inclined wire at an intersection at which a twine portion is formed. The second rightwards inclined wires intersects, in sequence, from the second rightwards inclined wire through the N-th rightwards inclined wire at an intersection at which a twine portion is formed. The N-th leftwards inclined wire intersects the N-th rightwards inclined wire at an intersection at which a twine portion is formed, thereby forming a net structure with a plurality of hexagonal meshes.
Abstract: The present invention is directed to a method for fabricating three, four, six, or eight-threaded knotlessly woven nets, which involves aligning at least a plurality of flyer wheels to form a braiding head, and then positioning two such braiding heads against one another. Bobbins are then positioned on recesses formed at discrete intervals along the circumference of said flyer wheels, and the bobbins are then rotated about said flyer wheels in figure-eight shaped fashion to weave a net shank. Then, the bobbins are rotated between the braiding heads in figure-eight shaped fashion to form a connection point between the net shanks.

Abstract: A loop for providing a ladderless woven fabric made from warp and weft threads and with a stitch-like appearance.In the loom the warp threads (3) pass into holes of thread guides which are mounted side by side on a shaft (7), rotatably drivable through approximately 180.degree. about its axis between first and second positions; the warp threads (3) initially define triangles at the center of which are provided openings (14) for the insertion therethrough of weft threads. During the forward rotating movement, the threads (3) close around the weft thread, and the latter leaves the thread guides by way of slots (15), after which, as the thread guides execute a return stroke, the triangles reform around the openings (14).
