  • Patent number: 4492135
    Abstract: A high speed slitter for slitting large sheets (3) of thin metal into rectangular strips has pairs of rollers (10, 10') mounted on parallel, driven shafts (12, 13). Each roller has a hub (98, 98') carrying a cutter ring (100, 100') with a circular cutting edge (112). A draw ring (92, 92'), cooperating with the opposite cutting ring (100', 100) to draw the sheet between the rollers, consists of a resilient ring (94, 94'), gripping the hub but capable of slipping around it when subjected to sufficient appropriate force, and a steel tire (96, 96'), carried only by the resilient ring and engaging the sheet. The tire can be deflected radially by virtue of the resilient ring.
