Abstract
An end edge detector and method for sensing and indicating an end edge along a roll of material. A sensor retained by a housing detects the end edge and triggers an output signal indicative thereof. The sensor can be formed by a light source for producing an illuminated area on the roll of material in combination with a light radiation detector. Light received by the radiation detector is processed to produce an electronic control signal, and an output signal is triggered when the light received reaches a predetermined threshold electronic control signal indicative of light scattering by the end edge. Alternatively, the sensor can comprise a probe with a tip that extends from the housing for traveling along the surface of the roll of material. Deflection of the probe by contact with the end edge trips an electrical contact switch and triggers the output signal.
