ABSTRACT:
A feed mechanism for feeding a web of rolled flexible sheet material, such as soft paper towels, out of a dispenser. The mechanism includes a feed roller within the dispenser and a web cutting blade in the feed roller and projectable and retractable therewith as the feed roller rotates. A contoured cam is attached to an end of the feed roller, and a spring-loaded cam follower presses against the contoured cam. The cam follower, through the cam, controllably assists in the rotation of the feed roller during the feed roller cycle when the blade cuts the web and thereafter to feed a free end of the material to an accessible position outside of the dispenser. The needed maximum pull forces by the user on the material to cut and withdraw the material from the dispenser are thereby significantly minimized, and the likelihood of the soft towel material tearing off in the user's wet hands is accordingly reduced.
