<p>An apparatus for profiling rod or wire comprises two pairs of driven profiling rollers (17) arranged normally one to the other, the rollers of each pair being spaced to engage the material at opposite sides thereof. The rollers (17) can be skewed at an angle ( alpha ) to the direction of travel of the material (22) to be profiled so as to produce in one operation a profiled rod or wire twisted along its longitudinal axis. <IMAGE></p> |
