A sheet material dispenser, comprising:
- a dispenser housing including a support mechanism for holding at least one roll of sheet material, and a discharge for discharging the sheet material from the dispenser housing;
- a dispensing mechanism including a drive roller configured to engage the sheet material, and a drive motor in communication with the drive roller to drive rotation thereof for dispensing of the sheet material from the discharge;
- a pressing roller arranged along the drive roller and configured to engage the sheet material between the pressing roller and the drive roller;
- and
- a drive belt assembly including a drive belt operatively connected to the drive motor and to the pressing roller for transferring power from the drive motor to the pressing roller for driving rotation thereof, and a biasing member engaging the drive belt to substantially maintain tension along the drive belt to urge the pressing roller toward engagement with the drive roller.
A sheet material dispenser, comprising:
- a dispenser housing including a support mechanism for holding at least one roll of sheet material along the dispenser housing, and a discharge for discharging the sheet material from the dispenser housing;
- a drive roller configured to engage the sheet material and drive the sheet material along a discharge path and towards or through the discharge in the dispenser housing for dispensing of the sheet material therefrom;
- a drive motor in communication with the drive roller to drive rotation thereof for dispensing of the sheet material from the discharge;
- a plurality of pressing rollers arranged adjacent the drive roller, with the sheet material engaged and passing between one or more of the pressing rollers and the drive roller;
- and
- a drive belt assembly including a drive belt operatively connected to the drive motor and to the pressing rollers for transferring power from the drive motor to the pressing rollers and driving rotation thereof, the drive belt biased in a prescribed direction so as to provide a substantially constant tension along the drive belt sufficient to urge the pressing rollers toward or into engagement with the drive roller.
