Abstract (en)
[origin: US4805433A] In a multi-roll rolling stand having two intermediate rolls 3 to 6, which each have only one tapered roll barrel end, in each case two tapered roll barrel ends lie on each side of the rolling stand. The intermediate rolls 3, 4 and 5, 6, the two roll barrel ends of which lie on the same side of the rolling stand, are independently displaceable in an axial direction. Due to the axial offset of the tapered roll barrel ends which can be achieved in this manner, the support curve of the work rolls 1, 2 in the edge regions of the rolled strip can be finely adjusted. In addition, the support curve in the center region of the strip can also be adjusted if in each case one of the two work rolls 3, 4 associated with each work roll 1, 2 is contoured.
