Abstract

The invention concerns a paper towel dispenser for dispensing rolled paper web sheet by sheet. The dispenser includes an electrically driven machinery for feeding the paper for displaying a sheet length after the previous length is torn off against a blade at the display opening of the dispenser. Devices are included to command the paper feeding machinery. The devices for commanding the paper feeding machinery include a vibration sensor connected to the blade and generating an electrical signal requesting a further sheet length from the paper feeding machinery.

Claims

1. A dispenser for dispensing paper towels sheet by sheet from a paper web roll, which dispenser includes an electrically driven feed machinery for feeding the paper web from the roll for displaying a paper web sheet length after the previous length is torn off by a consumer , devices to command the feed machinery, and a blade to cut the displayed sheet length from the paper web when the consumer tears off a sheet from the web, wherein the devices for commanding the feed machinery include a vibration sensor for the blade, the sensor generating an electrical signal initiating a request for a further sheet length from the feed machinery.

2. A paper towel dispenser according to claim 1, wherein the vibration sensor is a piezo-electric element.

3. A paper towel dispenser according to claim 1, wherein the signal from the vibration sensor is connected to the feed machinery over an electronic frequency filter.

4. A paper towel dispenser according to claim 1 wherein the electric signal generated by the vibration sensor is connected over a time delay element to the feed machinery.

5. A paper towel dispenser according to claim 1, wherein the feed machinery is further connected to a motion detector for an alternative request for a further sheet length.
