ABSTRACT:
An annular workpiece 6 is rolled between two oppositely disposed forming rolls 2, 4, and two oppositely disposed growth rolls 22 and 24 acting at right angles to the line of action of the forming rolls. The forming rolls 2, 4, are brought together to roll form the workpiece 6 to a wall thickness dependent upon its weight, and the advance of the growth control rolls 22, 24 is controlled to a position which is also dependent upon the weight of the workpiece 6.
