Abstract
Apparatus for straightening metal flanges of a cylindrical spool having a center longitudinal portion with a planar flange perpendicularly mounted upon each end thereof. The apparatus includes a pair of movable jaw assemblies which first engage the center longitudinal portion of the spool and then expand to provide a rigid support adjacent the inner planar surfaces of the spool flanges. A hydraulic control system is provided which senses the fully extended engagement of the movable jaw assemblies with the spool, and then actuates a hydraulic press to engage the outer surfaces of the spool flanges. The flanges are compressed between the movable jaw assemblies and the hydraulic press, thereby straightening out irregularities in the flanges. A second sensing device detects when the hydraulic press has reached its fully extended position and then actuates a control system which retracts both the movable jaw assemblies and the hydraulic press, thereby releasing the spool and resetting the system for the next cycle.
