ABSTRACT:
A dispenser guides a web from a roll of sheet material over a feed roller to a position to be grasped by the user while roller mounted knife means cuts the web into individual sheets and a manually engagable handwheel, rotatable with the feed roller, provides peripherally spaced finger notches to facilitate manual forward rotation of the roller in dispensing the material. The notches are formed differently in separate circumferential portions of the handwheel such that pawl means, successively engaging the notches incident handwheel rotation, prevents reverse rotation of the feed roller throughout a first portion of each feed roller revolution and biasing means acts to cause reverse rotation throughout a second portion of the feed roller revolution to assure return of the knife means to a safe inaccessible location within the dispenser when the handwheel is released.
