In a system comprising an upstream die plate (12) and a downstream die plate (14) for carrying out plastic processing with reduction of cross section on a moving strip or wire (F) of material, one drawing capstan (16) downstream of an upstream die plate (12), and a further drawing capstan (18) downstream of a downstream die plate (14), possible errors of rotational speed of the upstream capstan (16) with respect to the downstream capstan (18) are detected by measuring the volume of material that passes per unit time at a location upstream of the upstream capstan (16), which is the capstan being controlled, and at a location upstream of the downstream capstan (18), which is the reference capstan. The measurement must be made in the vicinity of the corresponding die plates (12,14)(it is not important whether before or behind). <IMAGE> |
