ABSTRACT:
A stop mechanism for a feed roller associated with a cutter in a dispenser for flexible rolled web material has a stop lever mounted to pivot in a plane normal to a feed roller rotational axis, such lever having a slot with lift and stop flanges disposed on opposite sides of the slot, respectively. A feed wheel rotatable with the feed roller has a control tab to successively engage with the lift and stop flanges so that as the feed roller rotates by web material being pulled from the dispenser, the control tab first lifts the stop lever by means of the lift flange and then abuttingly frictionally engages with the stop flange to retain the stop lever in its lifted position and stop feed roller rotation until the frictional engagement is relieved by pulling tension on the web being terminated whereupon the lever drops until the tab can pass over the upper end of the stop flange to free the feed roller for further rotation.
