<p>Each capstan (1) is composed of two concentric and coaxial parts, the first (2) of which driven by a motor (10) and comprising the typical capstan pulling face (2a), the second part (3) a freely-revolving ring (33) affording a run-out (3a) from which the wire (9) is drawn through a die (32) by and onto a successive capstan; the speed of the individual capstans is synchronized by a device (50) capable of monitoring both the angular movement (Sc) of the shaft (5) driving the first part (2) of the caps tan and the angular movement (Sa) of the ring (33), detecting any difference between the two, and correcting the angular velocity (Nc) of the shaft (5) accordingly.</p> |
