Abstract (en)
[origin: US4881396A] A rolling mill stand with work rolls which are supported as necessary by back-up rolls or by intermediate and back-up rolls. The rolls are axially slidable relative to each other. The bodies of the rolls are provided with alternatingly concavely and convexly shaped contours in such a way that the rolls supplement each other in at least one axial position of the rolls so that no gap exists between the rolls. Corrections of the roll gap between a pair of rolls can be carried out by relative axial displacement of the rolls. The contours of the rolls have in the neutral position thereof, in addition to a maximum inclination in the middle, maximum inclinations of the circumferential lines on both sides of the middle of the circumferential surfaces of the rolls in longitudinal direction of the rolls in which roll gap profile changes are to be effected.
