Abstract

Rolling stand for producing rolled strip having working rolls which are supported on supporting rolls or intermediate rolls and supporting rolls, wherein the working rolls and/or intermediate rolls and/or supporting rolls are arranged in the rolling stand so as to be displaceable axially relative to one another, and each roll of at least one roll pair formed from a supporting roll and a working roll or from a supporting roll and an intermediate roll has a curved contour which runs over the entire effective barrel length, wherein the contour (5) of the supporting roll (2) is predefined by a contour function (10) which is formed from a superposition of a first contour function ( 7 ) , which runs in a manner complementary to the adjacent working roll (1) in a non-displaced state, with a superposition function (8, 8') which is concave or convex in relation to the supporting roll axis (9).
