ABSTRACT:
Wire stock for connecting rods is run through the nip of a pair of obliquely toothed rolls having teeth which taper from one face of the roll towards the other, and have a larger radius at the tip than along the portions flanking the tip. The angle of obliqueness matches the angle that a turn of a spiral wire will traverse the connecting rod. Round wire stock for the single-faceted spiral wires is run through the nip of a pair of rolls one of which has a cylindrical surface (i.e., a flat longitudinal profile), and the other of which has a circumferential groove with a slightly larger diameter than the round wire stock. As the wire is flattened on one side, its curved side is broadened. As the resultingly single-faceted round wire is wound into flattened spiral form, it is spatially orientationally guided, so that the facet becomes located facing outwards. The rods and flat spirals are conventionally assembled with one another and secured to one another at respective ends, to provide a balanced flat spiral woven wire conveyor belt with rounds of turns nested in concave oblique crimp notches on the connecting rods.
