Abstract (en)
A pipe-rolling head comprises a body (3) rotating around a respective rolling axis (X); and at least three roll-holders (5) mounted on the rotating body (3), each adapted to receive a respective roll (6); the rolls (6) freely rotate around respective rotation axes (Y) that are substantially parallel to the rolling axis (X); the roll-holders (5) are susceptible of translation relative to the rotating body (3) between an open position at which the rolls (6) lie spaced apart from each other and from the rolling axis (X) and a closed position at which the rolls (6) lie close to each other in the vicinity of the rolling axis (X), to encompass a pipe (2) to be rolled which is coaxial with the rolling axis (X). The head further comprises a main motor (4a) connected with the rotating body (3) to set said rotating body (3) in rotation, and actuating means (9) to move the roll-holders (5) between the open and closed positions. The head is in addition provided with a control device (10) of the CNC type interlocked with the actuating means (9) for movement of the roll-holders (5) between the open and closed positions, to automatically control closing and opening of the roll-holders (5).
