Rolling stand, to roll rod or tubular materials, has a number of rollers (4-6) on one plane forming a central caliber opening (7). They are powered by a common rotary drive with a hollow wheel fitted with inner teeth set radially together by an eccentric. The roller shafts (9-11) rotate in eccentric bushes (24) at the roller housing, and they mesh together by bevel gears. The bevel gears (16a-16c,17) are mounted in separate cassettes (14,15), forced against the hollow wheel by a mechanical coupling (30,31).
