Abstract
Abstract The mounting of normally superimposed rollers in a roller stand, according to which each bearing housing for each roller has two outwardly extending arms extending in opposite directions with regard to each other, and in which the outer end portions of said arms are each provided with a cut-out for respectively receiving a threaded spindle and allowing the same to pass therethrough. Each of said arms has associated therewith a nut below the respective arm and adjustably mounted on the pertaining spindle, the distance between two spindles which are adjacent to each other being such as to permit withdrawal and insertion of said rollers in the direction of the longitudinal axis of said rollers and together with the pertaining bearing means for the rollers between the last mentioned two spindles.
