A combi roll includes a shaft having two spaced-apart stop rings a plurality of roll rings placed between the stop rings, which roll rings individually are composed of an outer ring of a hard metal, and a concentric inner ring of a more ductile metal, which is permanently bonded to the outer ring metallurgically, and has a flange that projects a distance axially from an end of the outer ring. The individual roll ring is rigidly connected to the shaft by way of one or more locking pins, which are inserted in through holes in the projecting flange of the inner ring and engage holes in the shaft. |
