A rolling stand is provided for producing a 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 of the supporting roll is predefined by a contour function which is formed from a superposition of a first contour function, which runs in a manner complementary to the adjacent working roll in a non-displaced state, with a superposition function which is concave or convex in relation to the supporting roll axis.

A roll bender apparatus is disclosed for bending a work piece, the apparatus including a base, a bending roller rotatably disposed on the base, a first guide roller rotatably disposed on base. and a second guide roller rotatably disposed on the base. A first work piece guide assembly is movable about the first guide roller and a second work piece guide assembly movable about the second guide roller. The first and second work piece guide assemblies are oriented to receive the work piece, and the first and second work piece guide assemblies are configured to move about the first and second guide rollers respectively in response to the work piece being bent as the work piece is advanced between the bending roller and the first and second guide rollers.

Systems and methods of applying a texture on a substrate include applying a texture to the substrate with a work stand of a coil-to-coil process. The work stand includes an upper work roll and a lower work roll vertically aligned with the upper work roll. At least one of the upper work roll and the lower work roll includes the texture. Applying the texture includes applying, by the upper work roll and a lower work roll, a work roll pressure on an upper surface and a lower surface of the substrate. The method further includes adjusting a contact pressure parameter of the work stand such that the work stand provides a desired contact pressure distribution across the width of the substrate and a desired thickness profile of the edges of the substrate while an overall thickness of the substrate remains substantially constant.

An apparatus (2) for flatting, punching or stamping a material (40) introduced into the apparatus (2), said apparatus (2) comprising a first cylinder (14) provided with an outer layer configured for flatting, punching or stamping the material (40); a back-pressure cylinder (16) extending parallel to the first cylinder (14) and an adjustment mechanism (22, 22′, 28, 28′, 34, 34′, 36) for adjusting the distance between the first cylinder (14) and the back-pressure cylinder (16). The adjustment mechanism (22, 22′, 28, 28′, 34, 34′, 36) comprises a first contact member (22) and preferably a second contact member (22′) brought into contact with the bottom portion (circumference) of the first cylinder (14). The contact member(s) (22, 22′) are mounted on a structure (34, 34′) being movably mounted relative to the back-pressure cylinder (16).

Within a housing, divided backing bearing assembled shafts are each moved on any one of a housing bore upper surface 8a constituting the housing, spray frame upper surfaces 9, and rails 13, 19, and 20 of a changing carriage 12 by a sliding apparatuses, and outside the housing, the divided backing bearing assembled shafts are extracted from within the housing or inserted into the housing by being moved on the rails 13, 19, and 20 of the changing carriage 12 by sliding apparatuses. There are thus provided a rolling mill that makes changing of divided backing bearing assembled shafts in the rolling mill easier than conventional, and a method of changing the divided backing bearing assembled shafts in the rolling mill.

A multistage rolling mill 100 includes support bearings 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h arranged on the entry side and/or the exit side of work rolls 2a and 2b, and supporting the work rolls 2a and 2b on an work side and a drive side. The offset positions in a pass direction of the pair of work rolls 2a and 2b for rolling a strip 1 are changed by moving in and out the support bearings 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h to the entry side or the exit side with respect to the pass direction. A multistage rolling mill capable of rolling a hard material efficiently and suitable for obtaining a strip of high product quality is thereby provided.
