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.

A tool for detecting a covered edge of a structural member through sealant material of a fillet seal includes an edge detection probe mounted to a fixture. The probe outputs an interrogation signal toward the covered edge and receives a return signal indicative of a location of the covered edge. The tool includes an electronic control unit (ECU) in communication with the edge detection probe and a display screen. The ECU is configured to generate, from the return signal, one or more XY coordinates indicative of the edge location, and to display the edge location on the display screen. Additionally, the tool includes a seal measurement device. In response to the edge location, the device measures a predetermined dimension of the fillet seal, including a thickness and/or a shape of the fillet seal. A method includes detecting the covered edge using the tool.
