摘要

Roll stand comprises at least three rollers surrounding a roller axis in a star shape. The bearings of the roller shafts (7) consist of roller bearings (13) and are located within eccentric bushings (14, 15). The bushings rotate in bores of the stand housing (2). The rotating position of the bushings can be changed using an adjusting device (17) and the bushings can be secured in all rotating positions. Preferred Features: The adjusting device is arranged on the front side of the stand housing and has a bevel wheel (19) which interacts with a toothed wheel or a toothed segment (20) of one of the eccentric bushings.
