ABSTRACT:
Method and apparatus for measuring the quality of the planar end surface of a wound roll comprising: optically projecting a line of light onto the planar end surface of the wound roll to generate and reflect an image of the line of light; focusing the reflected image onto an image sensor to obtain a data output; and feeding the data to a processor that measures deviations in the reflected image of the line of light that are caused by variations in the planar end surface of the wound roll.
