[Class 83 (iv)] Rolling ; cupping.-After pushing a tube billet on a mandrel through ring dies 4 or rolls, the return stroke of the rack 1 acts both to free the end 9 of the mandrel rod 6 from the recess 10 of the rack 1 whereby the fork 5 engages the collar 8 of the mandrel rod to strip the tube against a divided ring 14, the mandrel and rod so resting in the fork 5 and retained by the guide where it can be removed and replaced by a fresh cool mandrel and rod. The last die ring or roll pass may be oval to partly free the tube from the mandrel.
