The rolls of a rolling mill have working rolls which may be quickly changed, with the associated tools. The rolling machine has an angular trunnion, at least on one end of the working roll, supported in a divided clamping part of a driving shaft having a mating fixture. The other end of the working roll may have a circular trunnion or a non-circular trunnion removably supported by a guiding and supporting shaft.
