Abstract (en)

[origin: EP0235769A2] A four-, five- or six-roll rolling mill stand for strip 5 to be rolled with axially displaceable working rolls 3, 4 is to be further developed in such a way that, while avoiding the drop in thickness at the edges of the strip 5 to be rolled, high peak values of the surface pressure in the strip edge area are prevented as is the undesirably high wear resulting from these peak values. This is achieved by the working rolls 3, 4 each being provided with a flat annular hollow 8 in the area of one of their barrel ends such that this annular hollow 8 is disposed on the drive side on one of the working rolls and on the operating side on the other working roll, and during rolling the annular hollows 8 can each be pushed in the axial direction over one of the opposite edges of the material 5 to be rolled. This can be assisted by the arrangement of a flat annular reinforcement 7 between the annular hollow 8 and the barrel end of the relevant roll facing this annular hollow 8. <IMAGE>
