ABSTRACT:
The rolling mill or roll stand which makes a rolled product, particularly a rolled strip or strip, comprises a pair of working rolls, which if necessary are supported on a pair of supporting rolls or on a pair of the supporting rolls and intermediate rolls, and in which the working rolls and/or the supporting rolls and/or the intermediate rolls are axially slidable relative to each other. Each of the rolls of at least one of the pairs of rolls is provided with a curved contour extending to the roll body ends. These curved contours, sometimes on opposite sides, extend over only a portion of the rolled product width. The curved contour extends over the entire roll body length of each roll and has a shape such that both roll body contours entirely compliment themselves in a certain relative axial position. The working or intermediate rolls have the curve contours tapered to one of the roll body ends and widened toward the other of the roll body ends and are arranged slidable in opposite axial directions so that each of the tapered ends of the working rolls or intermediate rolls between a rolled product edge and the associated end of a supporting roll advantageously is held and aligned with each edge of the rolled product.
