ABSTRACT:
The invention relates to a rolling mill for tubes, in which a series of roll-holder containers (10) is housed in an external structure (2) extended along a rolling axis (L); the containers can slide inside the structure to be extracted therefrom and each one houses at least three rolls (17, 18, 19) controlled by respective driving motors (41, 42, 43). In accordance with the intervention the rolls (17, 18, 19) can be moved inside the containers (10) in a guided way along directions radial in relation to the rolling axis, in order to regulate the distance therefrom.
