The invention relates to a roll stand (1) for a continuous unrolling of several rolls (8, 8null) of reeled, web-like material, which are unrolled consecutively after each other in the roll stand, and which rolls are arranged to be changed by roll changing from an almost depleted roll (8) to a new, full roll (8) in said roll stand, which roll stand comprises a machine stand (2) with two gable sides (3, 4), which are arranged aloof from each other, a horizontally arranged hub girder (9) which is rotatably journalled at the gable sides and around which hub girder the rolls are arranged to be pivoted between an inlet side (6), to which new, full rolls (8) are delivered, and an outlet side (7) from which the web-like material is unrolled, at least two roll holders (10, 10null) which are arranged at the hub girder for handling of each roll and which roll holders each comprises two roll holding arms (11) which are mounted linearly displaceable laterally along one or several, axially along the hub girder and rigidity mounted tracks (12) and of which roll holding arms each is provided with a gripper (13) for seizure of a roll. According to the invention the roll stand also comprises a positioning arrangement (20) for an adjustment of the position of each roll holder (10, 10null) laterally along the hub girder (9) and for a mutual adjustment of each of the roll holding arms in each such roll holder after the width of the current roll in the roll holder, an adjustment device (21) at each roll holding arm for releasing of the grippers from a depleted roll and then for re-gripping of a new full roll in connection with roll changing and for a lateral precision adjustment of the position of one roll in relation to another roll and/or for a positioning of the material web to a desired web direction during the present unrolling.
