FIELD: plastic working of metals. SUBSTANCE: automatic machine has double-striker rotary forging head and device for returning strikers to the initial position. Returning device is formed as spring-biased inserts disposed at an angle of 90 deg. with respect to strikers for engagement with them. Entrance part of strikers is disposed at an angle of 8-15 deg. relative to its base and has wedge with inclined surfaces. Calibrating portion has stepped compensating part extending parallel to base. Steps are perpendicular to axis of feeding Height of steps corresponds to thickness tolerance value of rolled products.
