ABSTRACT:
A multiple groove pulley is formed from a cup-shaped blank by an apparatus and method in which axially displaceable segmental shaping rings are positioned at axially predetermined positions along the wall of the blank. Fluid pressure communicated to the interior of the blank expands the wall of the blank into contact with the shaping rings and at least one of the shaping rings is independently movable in an axial direction while the blank is compressed for simultaneous formation of the grooves. A sleeve member is movable axially over at least one of the shaping rings to resist radial movement of the segments while at the same time permitting full compression of the blank.
