Abstract

1501292 Web tension controlling apparatus BUTLER AUTOMATIC Inc 4 March 1975 [4 March 1974] 8968/75 Heading B8R A web tension controlling apparatus comprises a dancer roller assembly 12, Fig. 1, including a pair of rollers 32, 34 mounted pivotally on fulcrum levers 36a, 36b, and biased in the loop forming direction by a piston cylinder assembly 44, the angular displacement of the assembly 12 from a horizontal plane of reference being sensed by a potentiometer 56 producing electric signals which in conjunction with signals corresponding to the rate of angular displacement are applied to a controller 58 whose output signals depending on the direction of the angular displacement of the assembly 12, engage one or the other of an overspeed or underspeed clutches 62, 64, respectively, to restore the assembly 12 to its reference plane. In operation deflection of the assembly in the clockwise direction results in the potentiometer 56, Fig. 2, emitting a positive signal which is applied both to an amplifier 83 and a differentiator 85 (which takes account of the rate of deflection), the outputs of the amplifier and the differentiator being applied to a leg circuit 87 which feeds its output signal to the overspeed clutch firing circuit. The circuit 104 causes the clutch 62 to be engaged until the assembly is deflected in the anticlockwise direction. In a similar manner the potentiometer 56 emits a negative signal which prior to application to the underspeed clutch firing circuit 116 is passed through an inverter 96 to invert the signal to a positive one.
