Abstract
A rolling mill drive with at least one drive spindle arranged between a drive unit and a driven roll and terminating in a spindle head connected detachably to the neck of the roll. A coupling and decoupling device is arranged between the neck of the roll and the spindle head of the drive spindle. The coupling and decoupling device includes a coupling sleeve, a coupling pin inserted releasably into the coupling sleeve, and a locking element which is displaceable transversely to the axis of rotation of the neck of the roll. The locking element is inserted into the coupling sleeve and engages behind the coupling pin in an operating position of the locking element. The locking element is capable of being coupled to a displacing device for displacing it.
