Abstract
A web supply and take-up system in which the web is transported from a supply reel to a take-up reel by means of a capstan and pressure roller. The take-up reel is driven to wind up the transported web. The improvement comprises a roller mounted for restricted rotation and placed between the supply and take-up reels in frictional engagement with the web. The roller supplies a counter force to the take-up reel drive force which assists the capstan and pressure roller in stopping undesired web movement.
