The invention relates to a strand guiding unit and a method for positioning at least one roll segment of a strand guiding unit against a strand, the roll segment (110) comprising an upper and a lower roll support (114, 112), each of which bears at least one roll (116, 118) for guiding the strand (200) between the rolls. When viewed in the direction of the material flow, at least one respective positioning element is allocated to the tight-hand and left-hand side of the roll segment in order to position the two roll supports (112, 114) in relation to one another. The aim of the invention is to relieve the mechanical stress on a rolling frame that is connected downstream of the strand guiding unit, to relieve said frame of some of its previous tasks and to improve the quality of the strand. To achieve this, the separate positioning elements are individually controlled in such a way that the heights (Hr, Hl) of the right-hand and left-hand edges of the strand (200) are identical.
