Abstract
Mechanism for cutting a web of rolled flexible sheet material in a dispenser having a feed roller and pinch roller between which the web passes is provided with a knife mounted in the feed roller to be projected outwardly beyond the periphery of the feed roller during a web severing cycle wherein engagement of the pinch roller with the web immediately before the knife penetrates it acts to maintain tension in the web ahead of the knife and a high friction surface portion of the feed roller periphery which is in contact with the roll of material maintains tension in the web behind the knife as the web severing cycle proceeds while peripheral protrusions on the feed roller momentarily bump the roll out of contact with the feed roller during feed roller rotation to permit periphery which is in contact with the roll of material maintains tension in the web behind the knife as the web severing cycle proceeds while peripheral protrusions on the feed roller momentarily bump the roll out of contact with the feed roller during feed roller rotation to permit any loose loop of web behind the feed roller to slip along a low friction feed roller surface portion and jar the roll into parallelism with the feed roller to minimize potential build up of loose roll loops within the dispenser.
