A rolling stand including a pair of working rolls and associated backing rolls, the working rolls defining a nip through which a strip can be advanced in a succession of passes forming a single run, so that with each pass the thickness and widths of the strip are reduced. The working rolls have end regions projecting laterally beyond the longitudinal edges of the strip, and machining devices are provided on the frame of the stand to reduce the diameters of the projecting end regions of the working rolls after each pass during a single run so that the working rolls ony contact the respective backing rolls along a distance equal generally to the strip width. Each machining devices includes a support carrying a material-removing tool engageable with the juxtaposed end region of a respective run of the working rolls, each support being pivotable about the respective backing-roll axis and linearly displaceable along the respective working-roll end region to enable the respective tool to be moved both perpendicularly and parallel to the axis of the working roll. Respective stop elements pivotable about pivot axes parallel to the working-roll axes carry eccentric stops which are engageable with the tool supports to define the radially innermost end positions of the supports. |
