1. A method of regeneration of stop rings' regeneration, characterised in that external stop rings, from a disassembled stop stack are selected and the rings free from damage are qualified for regeneration, characterised in that each of the external stop rings qualified for regeneration is placed in and clamped in a split calibrating ring, which ring together with the regenerated stop ring is placed in a rigid casing of a die block, where the internal surface of the stop ring, being together with the die block in a spinning motion, is heated, preferably by means of induction, to the temperature from 780 to 800 degrees Celsius for approximately 20 seconds, then it is hardened by cooling with a cooling emulsion, then it is released in the temperature 250 degrees Celsius.2. A device for stop rings' regeneration, characterised in that it consists of a, mounted on a pin (7), rigid rotational cylindrical die block (3) of the inside conical surface, converging towards the bottom of the die block (3), inside of which is positioned, adjacent with its side surface to the inside conical surface of the die block (3), a split calibrating ring (2), having its external conical side surface of convergence angle corresponding to the convergence angle of the internal conical die block surface (3), and the internal side surface constituting cylinder's side surface.<IMAGE>
