Abstract
Beading apparatus is provided for producing a bead on the periphery of a hollow cylinder, such as a cam body. A rotatable inner ring and a rotatable outer ring co-act to deform a portion of the hollow cylinder therebetween to form a bead. To accommodate a firm backing of the exterior of the hollow cylinder during beading operations, while also permitting the removal of a beaded hollow cylinder from the apparatus, a depressor is provided which is formed as a basket with springing tongues separated by axially extending slots. A tapered cylinder liner is provided for forcing the springing tongues to a smaller diameter configuration to provide backing for the hollow cylinder during beading operations, with the springing tongues being movable to a larger diameter to permit removal of the hollow cylinder subsequent to beading operations.
