ABSTRACT:
A roll-forming apparatus is specifically designed to handle metal wires or other wire stock that is not for or is difficult for use in a drawing process, so that it can provide a reduced-diameter wire in a roll-forming process. The apparatus comprises a framed structure having four sides within which a pair of roll-forming rollers are arranged in parallel, one roller being powered by a driving power source, and the other roller being interchangeable. For a typical application, a plurality of such apparatuses may be arranged in series such that each unit is oriented at a right angle with regard to its adjacent unit.
