ABSTRACT:
A transducer measures the angular relationship between a drive and a driven member throughout a range of relative angular positions therebetween. The transducer provides a signal indicative of that angular relationship, and the signal can be transmitted to a controller that regulates the torque applied by the drive shaft. The transducer can be used in a web spooling apparatus where the position of the driven member relative to the drive shaft during web winding operation is a function of tension transients in the web. The transducer enables the system to adjust the torque of the drive shaft as a function of the angular relationship of the driven member and drive shaft so that the system can reduce tension transients in the web being wound onto the spool.
