Abstract

445,479. Automatic control of strip tension. BRITISH THOMSON - HOUSTON CO., Ltd., Ltd., Crown House, Aldwych, London. Oct. 11, 1934, No. 29144. Convention date, Oct. 11, 1933. [Class 38 (iv)] Strip material 10 is unwound from a reel 11 by a motor 13 which may be driven at various speeds, as for example by the Ward Leonard control shown. Constant tension is maintained on the strip by a dynamic braking generator 260 the current output of which is maintained constant, for example, by the vibratory regulator 33. In order that the tension may remain the same for all speeds of the strip the output of the braking g generator 260 is adjusted in correspondence with speed adjustments of the driving motor 13. The resistance absorbing the output may be a rheostat 31 coupled directly to the hand wheel 44 which adjusts the field strengths of the Ward Leonard machines. In a modification using magnetic contactors for bring- ing the driving motor up to a basic speed magnetic contactors vary the braking resistance and subsequent control is obtained by a speed controlling rheostat coupled with a braking rheostat.
