Abstract

Machine à tréfiler perfectionnée comportant des filières et des cabestans accouples, avec des quills d'entraînement, caractérisée en ce que la friction à couple constant, réalisée par perte hystérésis, comporte un << quill >> dont l'arbre menant est solidaire d'un anneau en ferrite orienté à grand champ coercitif présentant des pôles magnétiques permanents alternés et que l'organe mené - cabestan - est monté fou sur l'arbre menant et comporte un disque en alliage magnétique de faible champ coercitif, placé coaxialement en regard de l'aimant multipolaire avec un entrefer réglable.Improved wire drawing machine comprising dies and coupled capstans, with drive quills, characterized in that the friction at constant torque, produced by loss of hysteresis, comprises a "quill" whose driving shaft is integral with a ferrite ring oriented with a large coercive field having alternating permanent magnetic poles and that the driven member - capstan - is mounted idle on the driving shaft and comprises a disc of magnetic alloy of low coercive field, placed coaxially opposite the multipolar magnet with an adjustable air gap.
