ABSTRACT OF DISCLOSURE A disc roller mechanism and method for forming helical-shaped structures from a feed wire or rod, wherein the feed wire is drawn through a plurality of staggered disc-shaped forming rollers by rotation of the rollers, while the wire is also being rotated about its own axis so as to form the desired helical-shaped product. The roller mechanism includes a support frame and a first set of at least two fixed position driven disc-shaped rollers and a second set of at least one idler disc-shaped rollers, said idler rollers being transversely adjustable positions relative to the first driven roller set rotatably mounted in the frame. The driven roller set usually has a roughened outer perimeter surface to facilitate drawing the feed wire through the intersecting forming rollers. If desired, the feed wire can be pulled off a rotatable supply spool such as by a pair of guiding rollers and then passed through the staggered disc-shaped forming rollers to provide the desired helical-shaped product.
