Abstract: The invention relates to the production of low-residual-stress strip and is applicable in the field of metal forming. Pursuant to the invention, the gap between the finishing rolls is adjusted in n strip elements during the rolling process by adjusters in each case by amounts .DELTA.S.sub.i. However, it is not necessary that the number n of measurement zones be equal to the number of adjustment zones. The adjustment amounts .DELTA.S.sub.i for the individual strip elements are determined continuously, with the inclusion of the no-slip point (FIG. 1) by determining, either before or at the start of the roll pass, the average pass reduction .epsilon..sub.h,ges as well as the partial reduction .epsilon..sub.h,k, which characterizes the reduction from the no-slip point up to the exit side of the roll gap. The ratio .epsilon..sub.h,ges /.epsilon..sub.h,k formed from the two quantities, after multiplicative linkage with the final thickness h.sub.1, gives a fixed amount valid for the respective roll pass.

Abstract: A rolling apparatus has a grooved roll rotatable about an axis, having an outer roll surface, and formed with a radially outwardly open groove having a pair of frustoconical groove flanks extending to the outer roll surface and spaced axially apart at the roll surface by a groove width. Juxtaposed with this grooved roll is a ridged roll rotatable about an axis parallel to the axis of the grooved roll and formed with a ridge engaging radially in the groove, and having an at least partially cylindrical outer ridge surface centered on the respective axis and a pair of annular axially oppositely directed ridge faces flanking the ridge outer surface. The ridge outer surface forms with the flanks of the groove a rolling opening extending perpendicular to a plane including the axes and having a maximum dimension measured parallel to the axes which is smaller than the groove width.
