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.

Centering device for bodies having circular cross-section

A device for transporting nuclear fuel rod cladding tubes transversely along a production line has a travel surface for the tubes and a transport chain running in the direction of transport parallel to the travel surface. The chain has a plurality of two-armed levers pivotally mounted thereon and springs pulling these levers in the direction of the travel of the chain. The levers have rollers at their ends which can engage between tubes on the travel surface. The springs are of such strength that the resistance to movement of a predetermined number of tubes prevents them from rising up, so that the rollers roll underneath the tubes, but permits them to rise up when a small number of tubes is in front of them to engage the tubes and pull them along the track. This provides in effect a storage if too many tubes are found on the track at any one time.
