Abstract
A two roll sheet material dispenser cabinet for paper towelling and the like has an automatic transfer system from one roll to the other when one roll is exhausted. The dispenser feeds sheet material sequentially and comprises a cabinet with first and second roll stations and a feed mechanism to feed sheet material from the rolls to a dispensing opening. The feed mechanism has a gripping roller, and a pressure plate pressed against the roller to provide a feed passage between the roller and plate, a feed mechanism rotates the gripping roller, the sheet material from one roll station is retained in the feed passage while sheet material from the other roll station is dispensed. When the sheet material from one roll station is exhausted, the feed mechanism automatically dispenses sheet material from the other station.
Claims16
In a dispenser for sequentially feeding sheet material such as paper towelling from rolls of sheet material, including:
- a cabinet adapted to be attached to a wall, the cabinet having a dispensing opening for the sheet material;
- a first roll station in the lower portion of the cabinet;
- a second roll station above the first roll station;
- the improvement of a feed mechanism for feeding sheet material through the dispensing opening comprising:
- at least one gripping roller;
- pivoted pressure plate having pressure means to press the plate against the gripping roller to provide a feed passage for the sheet material between the gripping roller and the pressure plate;
- feed means to rotate the gripping roller and feed sheet material adjacent the gripping roller through the feed passage to the dispensing opening;
- retaining means for retaining the sheet material from the second roll station, positioned in the feed passage between the sheet material from the first roll station and the pressure plate when the sheet material from the first roll station is in the feed passage adjacent the gripping roller, the retaining means preventing the sheet material from the second roll station from feeding until the sheet material from the first roll station is exhausted, at which time rotation of the gripping roller feeds the sheet material from the second roll station through the dispensing openings.
A dispenser for sequentially feeding sheet material such as paper towelling from rolls of sheet material comprising:
- a cabinet adapted to be attached to a wall, the cabinet having a dispensing opening for the sheet material and side walls on each side of the dispensing opening;
- a first roll station in the lower portion of the cabinet;
- a second roll station above the first roll station;
- at least one gripping roller to grip the sheet material;
- pivoted pressure plate having pressure means to press the plate against the gripping roller to provide a feed passage for the sheet material between the gripping roller and the pressure plate, the pressure plate having a serrated lower edge for tearing the sheet material;
- feed means to rotate the gripping roller and feed sheet material adjacent the gripping roller through the feed passage to the dispensing opening;
- retaining means for retaining the sheet material from the second roll station, positioned in the feed passage between the sheet material from the first roll station and the pressure plate when the sheet material from the first roll station is in the feed passage adjacent the gripping roller, the retaining means preventing the sheet material from the second roll station from feeding until the sheet material from the first roll station is exhausted, at which time rotation of the gripping roller feeds the sheet material from the second roll station through the dispensing opening.
The method of sequentially feeding sheet material, such as paper towelling from rolls of sheet material, from a dispenser having:
- a cabinet adapted to be attached to a wall, the cabinet having a dispensing opening for the sheet material;
- a first roll station in the lower portion of the cabinet;
- a second roll station above the first roll station;
- the method comprising the steps of:
- feeding sheet material from a roll in the first roll station through a feed passage between a gripping roller and a pressure plate to the dispensing opening;
- positioning sheet material from a roll in the second roll station through the feed passage between the sheet material from the roll in the first roll station and the pressure plate, and
- preventing sheet material from the roll in the second roll station positioned in the feed passage, from feeding through the feed passage when rotation at the gripping roller feeds sheet material from the roll in the first roll station through the feed passage to the dispensing opening, until the sheet material from the roll in the first roll station is exhausted, at which time rotation of the gripping roller feeds the sheet material from the roll in the second roll station through the feed passage to the dispensing opening.
