Abstract: A new method for rolling threads is proposed. This extends the technological possibilities of the thread-rolling process with tangential heads by machining threads that are not limited in length to the rollers, as is the case with tangential heads. This allows to control the size and direction of the working axial feed of the rolling rollers, by varying the diameter and therefore the angle of inclination of the threads of the rollers, which in its turn allows to take into account the specific technological conditions of the processing. This is achieved by the fact that the combination and sequence of the types of working feeds and a new mutual initial setting of the rolling rollers and parts are regulated, which, when co-executed, rolls the threads of unlimited length when using tangential thread rolling heads
