The invention relates to a so-called combi roll comprising, on one hand, a shaft (1) having two spaced-apart stop rings (2, 3), and on the other hand a number of roll rings (4) placed between the stop rings, which roll rings individually are composed of an outer ring (6) of a hard metal, and a concentric inner ring (7) of a more ductile metal, which is permanently bonded to the outer ring metallurgically, and has a flange (12) that projects a distance axially from an end of the outer ring. According to the invention, the individual roll ring (4) is rigidly connected to the shaft (1) by way of one or more locking pins (19), which are inserted in through holes in the projecting flange (12) of the inner ring and engage holes (21) in the shaft. |
