Postforming apparatus

A postforming apparatus can be compared to a straightener in that its design is largely similar. Unlike a straightener, however, it is used solely to form process multi-wire type materials such as strands or ropes. The forming is called postforming because the apparatuses, which can be grouped together in postforming systems, are usually positioned downstream from the stranding point on the stranding line. Upstream from the stranding point the material is usually subjected to preforming by preforming heads. Both the preforming and postforming operations are performed for the express purpose of minimizing the recovery efforts of individual elements in the strand or rope structure as well as the internal stresses of the final product, which correlate with the forming conditions.
