Abstract:
Arrangement for changing the nut (11), the latter holding a roll ring, on a cantilever-mounted roll shaft (2) having a thread (13) for the nut (11), by means of a changeover apparatus. This has a threaded sleeve (50) which is provided with a thread (12a) that matches the thread (13) of the roll shaft (2) in order to take the nut (11). It has a centring device (49) for placement in alignment against the roll shaft (2). To ensure that the nut (11) can be screwed onto the roll shaft (2) from the threaded sleeve (50) even when the position of their threads does not match exactly, the threaded sleeve is moveable and inhibited against rotation in relation to the centring device (49) and/or in relation to the roll shaft (2).
