ABSTRACT:
There is disclosed apparatus for rewinding a web. The apparatus comprises a simple inexpensive clutch arrangement which gradually applies and removes driving force from a rewind shaft. A pair of bearing sleeves are received about the shaft. The sleeves have cooperable cam surfaces. The first sleeve is continuously driven. A roll in contact with the web senses the tautness or slack in the web and selectively operates a cam to move the sleeves into and out of camming cooperation. When in camming cooperation, the first sleeve binds on the shaft to effect clutching and consequent rotation of the shaft.
