METHOD OF PRESSING ROLLING OF THE RUNNING SPRING OF THE HOUR MECHANISM Russian patent published in 2019 - IPC G04B5/00 

FIELD: watches and other time measuring instruments.

SUBSTANCE: invention relates to the production of running springs of clock mechanisms. A method of press rolling of a running spring made of wire containing a preformed loop, in which a roller press is used, comprising a first guiding means, applying force to the specified wire in the first contact zone located between the second and third contact zones located on the second and third support-guiding means, for twisting located after the specified loop of the area of accumulation in the direction opposite to the direction of twist of the specified loop, while in the process of moving said wire, the position of the first contact zone gradually changes in such a way that said first contact zone gradually moves away from the second and third contact zones, to change the press rolling radius from the first, minimum, value to the second, maximum, values on the neck at the junction of the specified area of accumulation with the specified loop.

EFFECT: simplifies the process of manufacturing the spring, provides the possibility of transportation and storage in a flat state.
