ABSTRACT:
A dispenser for coiled sheet material, such as paper towelling, having an improved transfer mechanism for transferring feed from a partially consumed roll of sheet material to a fresh or reserve roll. The sheet from the partially consumed roll is fed across an apron to a pair of cooperating feed rolls. The transfer mechanism comprises a sensing finger carried by a pivotable frame which rides on the sheet material being dispensed from the partly consumed roll. When the end of the sheet material moves past the finger, the finger being unsupported, will drop through an opening in the apron to thereby pivot the frame downwardly and cause a roller to move the free end of the sheet of the reserve roll into the nip between the feed rolls so that the sheet from the reserve roll will then be fed from the dispenser. A pivotable discharge plate is mounted at the discharge opening of the dispenser and can be pivoted between a controlled feed position and a free feed position. When in the controlled feed position, only predetermined lengths of the sheet can be dispensed, but when the plate is in the free-feed position, a continuous length of sheet can be dispensed.
