ABSTRACT:
An automatic dispenser for paper towels shaped in strips of an appropriate length severable from a continuous feed roll, outputs a portion of paper of an appropriate length cutting it with a stationary blade. The blade is located in a less accessible area of the apparatus for user safety reasons. Dispensing is usually controlled by a photoelectric cell or proximity detector, which actuates an ON-OFF switch for supplying power to a motor during a time period predetermined by a timer, thereby causing rotation of a dragging roller adapted to cause a certain extent of unrolling of the feed roll. In case of saturation of the photoelectric cell caused by improperly keeping it intercepted, an electronic switch disables the photo cell and enables an emergency push-button while also lighting a signal lamp to advise of a change in the operating condition, which requires a push of an emergency button.
