A device for feeding transverse wires above and below a production line for mesh mats which consist of welded transverse and longitudinal wires, said device comprising an upper transverse wire feeder, which has a guide channel and which is arranged in a first position, in which transverse wires are fed along the guide channel of the production line, and comprising a lower transverse wire feeder, by means of which transverse wires can be conveyed from below to the production line, wherein a lower transverse wire store is provided, from which transverse wires can be removed by the lower transverse wire feeder, and wherein the upper transverse wire feeder is designed as a transverse wire switch, which can be pivoted at least into a second position, wherein the lower transverse wire store can be loaded with transverse wired by the transverse wire switch in the second position.

Fence mesh including line wires, and stay wires extending laterally across and intersecting the line wires to form a mesh, wherein a first type of wire knot is formed by a knot wire around the line wire and stay wire at intersections of the stay wires with the line wires in a primary zone, and wherein a second type of wire knot is formed by a knot wire around the line wire and stay wire at intersections of the stay wires with the line wires in a secondary zone, characterised in that the first type of wire knot is different from the second type of wire knot; and a machine for the formation of such a mesh.

A chain link fence and a method of manufacturing an improved selvage therefore that provides no exposed ends of wires. The chain link fence of the present invention is manufactured from a plurality of wires coupled in a woven format so as to form loops. The chain link fence includes slats woven through the plurality of loops so as to provide privacy subsequent installation. The chain link fence manufacturing method provides for an improved selvage at the top and bottom thereof wherein the selvage has no exposed ends and as such eliminating the deficiencies of traditional selvages. The method of the present invention includes providing a plurality of bends to the exposed ends of the wire comprising the chain link fence. The plurality of bends culminates in the formation of a novel selvage that has the exposed ends of the wire penetrating into the body of the plurality of slats.
