ABSTRACT:
A roll stand without roll housings has at least two work rolls which are mounted in roll bearings and which each extend along a roll axis, wherein the rolls define a roll gap and the roll axes define a roll plane, so that the roll plane contains both roll axes, wherein the roll bearings are connected to each other through two groups of connecting elements, and wherein one group of connecting elements each is arranged on each side of the roll plane. The connecting elements of the groups are adjustable over an adjusting length distance, wherein at least one of the groups is adjustable under load by an adjustment drive in the adjusting direction over an under-load length distance and wherein the under-load length distance is substantially smaller than the adjusting length distance. With respect to the portion of the adjusting length distance which exceeds the under-load length distance, the groups of connecting elements are constructed so as to be without drive.
