Abstract (en)
[origin: US5007273A] In a multi-roll stand having laterally supported working rolls 4, each working roll 4 is supported at at least one side against a radially unmounted lateral intermediate roll 5, which, for its part, is supported against a first, radially mounted supporting roller 6 and a further, radially unmounted intermediate roll 7. The further intermediate roll 7 is supported against a second, radially supported supporting roller 8 and against that intermediate roll 3 of a six-high roll stand which supports the working roll 4 vertically or against the supporting roll of a four-high roll stand. By virtue of this type of lateral support, the risk of slip between the working roll 4 and the lateral intermediate roll 5 supporting it is reduced because a torque is transmitted to the intermediate roll 5 from the intermediate roll 3 or supporting roll of the roll stand via the further lateral intermediate roll 7. In addition, the space for the lateral support can be better utilized for an increase in the supporting forces.
