Abstract (en)
[origin: EP2244138A1] The device has a winding system comprising winding arms (2, 2') for rotating a winding wheel, and an instantaneous disengaging module (11) for disengaging the winding wheel when a mainspring of a barrel is not working in a given tension range. The disengaging module comprises an instantaneous drive head mounted coaxially on an axle, and a setting wheel (17) rotated around the axle by intermediate wheels that are engaged with the barrel and a ratchet. The module has a disengaging lever (14) cooperating with a cam (18) of the module, and disengaging the winding arms from the winding wheel.
