ABSTRACT:
A stop mechanism for a feed roller associated with a cutter in a dispenser for flexible rolled web material has a stop lever which provides a substantial mechanical advantage. The increased mechanical advantage permits the vacuum cups of a vacuum cup timer to be effortlessly and reliably set. The stop lever has a long actuating arm which pivots about a pivot point. The long actuating arm creates a substantial mechanical advantage for setting the vacuum cups in vacuum-gripping engagement. The mechanism advantage greatly enhances the low pull force requirement and smooth operation of the dispenser.
