摘要： The present invention relates to a rolling mill 20 which defines a rolling axis X and comprises at least two rolling stations 22. At least one rolling station comprises a fixed structure 40, a roll-holder cartridge 24 and three actuators 32. The cartridge is connected removably to the fixed structure and comprises three rolling rolls 26. The rolls are movable radially and rotatable about three respective axes arranged at 120° from each other. The three actuators are mounted on the fixed structure and comprise pistons 50 movable along respective radial axes t arranged at 120° from each other. Each of the actuators is able, during use, to act on one of the rolls so as to impart a radial force suitable for rolling the article 44. The rolling mill 20 according to the invention is characterized in that the three actuators are of the single-stroke type and are arranged so that, when the pistons of two actuators are completely retracted to the end-of-travel stop of the working stroke, a path P is created free from obstacles and parallel to the axis of the third actuator. The path P which is created is such that allows the cartridge to pass out laterally on the opposite side to that where the third actuator is situated.
