Employed for coarser wire meshes, usually ½" mesh or coarser.
First, the number of wires to make up the width of the roll is calculated (the warp wires). The wire is run through a series of gears (crimping wheels) to achieve the desired crimp, such as intermediate, lock, or smooth top. If the roll is 100 feet in length, the wire is crimped, then the required number of warp wires are cut to 100 ft lengths. The wires are threaded through slots on the loom to keep them the proper distance apart. Next, the number of wires to make up the length is calculated (the fill wires). The fill wire is run through the crimping wheels and the required number of fill wires are cut to size. If the roll is to be 36" wide, the fill wires are cut to 36" lengths. The fill wires are fed across the warp wires, over one wire, under the next one, and so on, one fill wire at a time, until the roll is complete.
Employed for fine and some coarse wire meshes, usually ½" mesh or finer. First, the number of wires to make up the width of the roll is calculated (the warp wires). Next, the required number of warp wires are wound around a drum, called a beam, enough turns to make up the length, and the beam is attached to the loom. Then, the loose ends of the wires are threaded through a series of slots on the loom, to keep the wires the proper distance apart, and tied to a take up drum. A bobbin of wire (the fill wire) is threaded over one warp wire and under next, and so on across the width. The bobbin then travels back in the other direction, creating looped, or selvedge edges. The bobbin continues traveling back and forth, with the finished portion wrapping around the take up drum.
