ABSTRACT:
A special marker is disclosed that is affixed to a stationary or moving web near the lateral web edge to designate defective material. When edge trim is removed from the web, the trim removal device also cuts-off the front end of the marker so that the remaining portion is momentarily flush with the new web edge. This cutting action activates the remaining portion of the marker so that a component of the marker advances to extend out beyond the new web edge such that it is visible after the marker is wound into the rewind roll. This ability to see where the web was initially marked, after edge trim is removed, eliminates the conventional inaccurate and wasteful practice of remarking the web.
