ABSTRACT:
The present invention is a dispenser that, in one embodiment, includes a support for a roll of web material, a drive roller cooperating with an idler roller to feed web material supported by the roll support, and a mouth through which the web material is dispensed which has a floor but not a roof such that the web material does not jam when dispensed through the mouth. In another embodiment, the mouth is slot shaped. In various embodiments of the invention with either a slot shaped mouth or a wide mouth without a roof, a sensor is provided for selectively activating a drive motor in response to an incursion into a sensing field, wherein the sensor comprises an infrared emitter and receiver.
