ABSTRACT:
A wire fabric and apparatus and method of making same including processing wire to produce a wire fabric of open construction and with the wire fabric formed with small openings relative to the gauge of the wire so as to form a security mesh, including coiling the wire to have small loops, cutting the coiled wire into individual lengths by cutting out a small portion of an individual loop of the coiled wire, repetitively interweaving the coiled wire before the coiled wire is cut with the coiled wire lastly cut to form the security mesh with the interweaving operation of one individual length of coiled wire at a time, and alternately shifting the coiled wire forward and backward for successive interweaving operations for providing the proper orientation for interweaving between the lengths of coiled wire before each interweaving operation.
