Abstract
An apparatus and method for determining sheet material edges on a surface including a sensor configured to detect an outer edge and a usable edge of the sheet material and a controller in communication with the sensor. The sensor comprises a first color optical sensor producing a first signal representing a first physical attribute of the sheet material and a second color optical sensor producing a second signal representing a second physical attribute of the sheet material. The controller comprises a processor, a memory, and a communications adapter, controls dispensing and spreading of the sheet material for detection by the sensor, and signals to a user a presence of the usable edge in the sheet material upon detection by the sensor.
