    • The invention relates to a method and a device for applying an adjustable tensile-stress distribution, in particular in the edge regions during the cold-rolling of metal strips (16), in particular metal foil, in order to reduce the risk of an excessive build-up of tension and cracks at the edges of the strip, which can lead as a negative consequence to cracks in the strip and to a reduction in production, and in order to improve the surface of the strip and its planarity, even for a relatively high strip displacement speed, and also to reduce strip trimming widths. To achieve these aims, at least one or a combination of two of the following measures are implemented: a) separation of lubrication and cooling of the working rolls by lubricating on the run-in side and cooling on the e discharge side, b) additional influencing of the strip edges using a hot edge spray”, in particular by spraying (21) rolling oil with differing temperatures in zones, c) use of a special cross-sectional configuration of the working rolls (12, 12′) in the vicinity of the strip edges, which creates a partial material build-up during the blooming pass, said build-up forming a longer strip edge with subsequent passes, thus counteracting the risk of an excessive build-up of tensile stress.

    • The invention relates to a Sexto-type roll stand with x3 grinding, in which a large difference in diameter between the intermediate rolls (20, 21) causes increased wear and rough surfaces on the support rolls (31, 31) during operation, the damage pattern on the support rolls (30, 31) corresponding to the shape of the CVC grinding following an extended operating time. In Quarto-type roll stands, the grinding amplitude is initially also significantly greater than is required for rolled programs, thus resulting in the unfavorable wear pattern as well on the support rolls. The aim of the invention is to minimize said flaws. Said aim is achieved by the fact that the surface length (L) of each intermediate roll (20, 21) in a Sexto-type roll stand or each working roll in a Quarto-type roll stand is composed of a cylindrical section (Z) and a convexly curved section (R(x)). The transition point (A) from the cylindrical to the curved section of the surface length of the rolls can be selected within the range L/2
