An electronically controlled roll towel dispenser with a data communication system. The dispenser automatically dispenses a predetermined length of paper toweling from a supply roll after a length of toweling has been detached by a user pulling and tearing the protruding toweling against a stationary cutting blade. The dispenser is battery powered with an electric motor, an electromechanical dispensing mechanism, and an embedded microcontroller for controlling and monitoring operation of the dispenser. In addition to primary control functions, the microcontroller monitors parameters such as battery condition, towel usage, system status, system errors, and unsafe operating conditions. Pushbutton switches are also provided for programming towel length and the dispense delay. The dispenser further includes an optical transmitter for transmitting visual and infrared data to a receiving device. Useful information about the status of the dispenser can be visibly discerned by an operator through the use of primitive low-speed flash patterns, while high-speed infrared digital data can be simultaneously embedded in or multiplexed with the visible data.

Electronically controlled roll towel dispenser with data communication system

The device for dispensing paper towels has a housing for holding a generally vertical stack of the paper towels and including a lower portion through which individual towels can be dispensed. The lower portion includes an elongated opening through which a fold of the bottommost towel can extend and be accessible for a user to grab and pull the bottommost towel from the stack. Improved towel dispensing is enabled by laterally spaced and upwardly-directed ramps located in the vicinity of the front edge of the opening and upon which an edge of the stack rests, opposed end pads angled downwardly to the opening and upon which the stack ends rest, and/or a bottom cabinet portion angled with respect to the rest of the cabinet to transfer stack weight. The opening preferably is shaped to cause the fold of the bottommost towel to assume a C-shape.

Folded paper towel dispenser

The device for dispensing multi-fold paper towels has a housing for holding a generally vertical stack of the paper towels and including a lower portion through which individual towels can be dispensed from the stack. The lower portion includes an elongated opening through which a fold of the bottommost towel can extend and be accessible for a user to grab and pull the bottommost towel from the stack. One side portion of the towels rest on a plurality of laterally spaced ribs or ramps located in the vicinity of the front edge of the opening and inclined at an angle upwardly and forwardly relative to the front edge. These ribs or ramps effectively transfer a portion of the pressure applied by the stack on the bottommost towel toward the rear, thereby reducing the force required to pull the bottommost towel from the stack. The opening preferably is shaped to cause the fold of the bottommost towel to assume a C-like shape and thereby reduce the amount of the fold readily accessible to a user.
