Abstract: A sheet feeding device of the present invention includes a cutter capable of being moved back and forth by hand between two reference positions outside of a sheet conveyance range. When the cutter is held in a halt at a position other than the reference positions, the sheet feeding device returns a sheet toward the upstream side by a preselected amount and then returns the cutter to one of the reference positions. Even when the cutter moved by hand for the replacement or the replenishment of a sheet is left in the sheet conveyance range, the cutter is prevented from again cutting the leading edge of the sheet when returning to the reference position. This protects the leading edge of the sheet from defective cutting.

Abstract: A paper towel dispenser which provides for hands free, automatic feeding of the first sheet of a primary web roll, such as a paper towel roll, into a feed mechanism when its cover is closed. The dispenser also automatically transfers its web feed supply from a primary roll to a reserve roll upon the exhaustion of the primary roll. The present invention eliminates the need for an attendant to thread the leading edge of a primary or reserve roll into the feed mechanism of the dispenser. The dispenser also eliminates wasted paper because it does not begin to feed the reserve roll until the primary roll has expired. The dispenser can include either a manual feed mechanism or a powered feed mechanism. The dispenser relies on a sensor for determining when a portion of the web is absent from a side of the feed mechanism proximate a web discharge opening.
