PCT No. PCT/FR95/00887 Sec. 371 Date May 27, 1997 Sec. 102(e) Date May 27, 1997 PCT Filed Jul. 4, 1995 PCT Pub. No. WO96/06557 PCT Pub. Date Mar. 7, 1996An apparatus for safely controlling a paper cut-off device in a paper towel dispenser in which a knife of the cut off device can effectively be locked in a stop position within a recess of a drum. Alternatively, the apparatus can lock the knife in a position of initial rotation within the recess of the drum prior to ejection of the knife. The knife is locked in either of these positions by stopping mechanisms arranged on the lateral side of the housing of the towel dispenser at a location of a fixed cam with a plurality of radiating fingers, and near the end flange of the drum opposite a heel-shaped pinion, respectively. A rotation control mechanism disposed at the base of the housing ensures swiveling and retraction of the knife into the recess formed on the drum. |
