Abstract
An arrangement for centering a tube includes guides on which are mounted blocks slidable towards and away from each other by a hydraulic cylinder arrangement. Each of the blocks has a frame pivoted on it to rock about an axis perpendicular to the direction of movement of the blocks, the turning movement of the frames on the blocks being limited by an adjustable set screw and a spring on opposite sides of the frame pivot. Each frame carries either two rollers turnable on spaced axes which are parallel to the length of the tube or a single roller mounted to turn on an axis perpendicular to the direction of movement of the blocks, this roller having a central portion of small diameter and end portions of greater diameter.
