Patent ID: 8413476

Claim:
A rolling mill stand for the production of rolled strip or sheet metal, comprising: a pair of working rolls positioned and extending in directions so as to form a roll nip; a respective intermediate roll outward of each working roll and operable to support the respective one of the working rolls during rolling; a respective supporting roll outward of each intermediate roll and supporting the respective one of the intermediate rolls during rolling; the intermediate rolls arranged in the rolling mill stand so as to be displaceable axially with respect to one another, a device for axially displacing the intermediate rolls, each intermediate roll having a first curved barrel contour which runs over an entire effective barrel length of the intermediate roll, the first barrel contour being described by a first trigonometric function, each supporting roll having a second complementary barrel contour described by a second trigonometric function, the first barrel contours of the intermediate rolls being shaped for completing the second barrel contours of the respective supporting rolls in a complementary way, such that in a non-loaded state, solely in one specific relative axial position of the rolls of the pair of intermediate rolls, a partial or full completion of the second barrel contour of each supporting roll and the first barrel contour of a respective directly adjacent intermediate roll occurs in the non-loaded state, the first barrel contours and the second barrel contours having no kinks therein, no continuous edges generated by such kinks being formed on any of the intermediate rolls or the supporting rolls.
