Referring more particularly to the drawings, the reference numeral 2 indicates a shaft for supporting a rotatable object supporting member 4. In this instance the to of the surface 6. A sleeve is mounted on each of the surfaces 8 and since the sleeves are identical in strucings 16 and 18 through its outer wall and rollers 20 and 22 are mounted in the openings 16 and 18, respectively. The axis of each of the rollers 20 and 22 is in a plane perpendicular to the axis of the rotatable member 4. The roller 20 extends into a longitudinally extending groove the sleeve 10 cannot rotate The shaft of the roller 20 is preferably mounted in eccentric bushings 26 to provide for adjustment of the roll 20 radially of the member 4. Spaced apart circumferential rings 28 are secured to the outer surface of the sleeve 10 in order to provide a space nie States Patent 0 2,766,041 Patented Oct. 9, 1956 removed because the diameter of the sleeve at this point is less than the diameter ends.

tions and modifications may be made Without departing from the scope of the following claims.

I claim:

1. Apparatus for automatically centering moving elongated objects comprising a rotatable object supporting structure, a sleeve slidably mounted on said structure at each side of its object supporting surface, means for positively causing said sleeves to rotate with the object supporting structure, a diametergreater than the diameter ofsaid object supporting surface adjacent thereto to provide a shoulder, .means operable when said structure is rotating for moving .said sleeves axially, eluding apair of opposed rotatable ilobj'ect passes, the axes "intersecting at a point between the rolls and diverging "away from the direction'of approach of the object, and

same direction and at the same angular velocity,

a fla ge on each of said sleeves having said object supporting structure in- 7 rolls over which the of rotation of said rolls underload said rolls to rotate in the each of said shoulder tomeans for positively causing said rolls increasing in diameter from ward its inner end.

' 2 Apparatus for automatically centering a nioving elongated object comprising a rotatable object supporting structure, a'sleeve slidablyi mounted on said structure at each side of .its object supporting surface, a flange on each of ,saidsleeves having a diameter greater than the diameter ofsaid object supporting surface adjacent thereto to provide a shoulder, each of said sleeves having a plurality of openings through the wall thereof, a roller mounted in each of said openings with its axis in a plane perpendicular to the axis of said structure, said rollers extending inwardly beyond the wall of said sleeve and bearing on the said rotatable structure, said object supporting structure 25 having a longitudinally extending groove in its outer sur- "when "said' structure is rotating positively causing slaid r o lls' face for receiving one of said rollers, means operable i for moving said sleeves axially, said object supporting structure including a pair of opposed rotatable rolls over which the object passes, the axes of rotation of said rolls under load intersecting at a point between the rolls and diverging away from the direction of approach 'of the object, and means for H to rotateinthe same direction and atthe same angular velocity, each of said 'rolls increasing in diameter from said shoulder toward its inner end.
