Abstract
1,088,513. Automatic tension control. W.H.A. ROBERTSON & CO. Ltd. Dec.3O, 1965 [March 4, 1965], No. 9226/65. Heading G3R. A pulley mounted on a pivoted lever forms a loop in material to be wound on a drum and movements of the lever control an electromagnetic friction brake associated with the drum drive to maintain constant tension. As described, wire from a wire drawing machine is wound on to a drum driven by an A. C. motor associated with an electromagnetic clutch and brake. Variations in tension are detected by variations in the position of a pulley urged against the wire by spring tension applied to a lever on which the pulley is mounted. Movements of the lever in one direction or the other from a mean position corresponding to a desired tension, produce electrical signals of one polarity or the other to increase, after amplification, the energization of the clutch or brake to correct the tension automatically. Signals from a tachometer generator operated by the lever are also introduced to improve stability of the control system.
