A slitter for webs, such as sheet aluminum or other metals, has a simple and effective method and apparatus for controlling the movement of a strip of metallic trim into a scrap reclamation system. One or more air nozzles direct a stream of air between the knife roll and the trim strip in the area where the trim strip leaves the knife roll. This presses the trim strip away from the knife roll, and reduces the risk that trim will adhere to the knife roll and cause problems.
