Drive device for rotating hollow elements |
摘要 |
A drive device for rotating a hollow element (31) comprises at least three pads (32) movable between a first position where the hollow element (31) can be threaded onto the device (30) and a second position where each pad (32) is moved radially in relation to an axis of rotation of the device (30). The device (30) further comprises a mechanism (33) for actuating the pads (32) in such a way that when a hollow element (31) is on the device (30), each pad (32) is at an approximately equal distance from the axis of rotation of the device (30).
