ABSTRACT:
A method of forming to shape an initially annular workpiece in which the workpiece is rotated and squeezed between a pair of opposed forming rolls at least one of which is advanced relatively towards another. A pair of opposed growth control rolls are situated at right angles to the forming rolls, contacting the outer surface of the workpiece during at least a part of the rolling by the forming rolls. When the forming rolls have advanced to a predetermined depth of roll the force exerted by the growth control rolls on the outer surface of the workpiece is increased and the rolls continue to move towards one another until an adjustable dead stop is reached.
