GAB//FTH9034 The transfer assembly for a dispensing cabinet for dispensing wound sheet material, such as paper toweling, from a primary roll and a reserve roll includes a transfer arm having a pair of dispensing fingers under which the leading end of the sheet material from the reserve roll is disposed and a sensing arm including a sensing surface over which sheet material from the primary roll being fed into the nip between a drive roller and a pressure roller rides. The transfer arm and sensing arm are mounted for common movement between a non-transfer position wherein the sheet material riding over the sensing surface of the sensing arm, in cooperation with the pulling force being applied thereon by the drive roller, holds the transfer finger away from the nip and a transfer position wherein, in response to the tail end of the sheet material being detached from the primary roll, the transfer arm moves toward the nip and the transfer fingers push sheet material from the reserve roll into the nip. Subsequent rotation of the drive roller causes the sheet material from the reserve to be fed through the nip and dispensed from the cabinet. |
