Abstract (en)

An annular locking device (10) for the winding of reels is intended to be arranged alongside a plurality of similar annular devices so as to form a winding shaft in a winding machine. The device comprises an inner ring (11) and an outer ring (12) which are concentric and engaging elements (13) which emerge through slots (14) on the peripheral surface of the outer ring. The outer ring is rotatable relative to the inner ring between a first angular rest position, in which the engaging elements (13) may retract inside the outer ring by a first amount, and a second angular position, in which the engaging elements (13) may retract by a smaller amount than in the first angular rest position. The engaging elements (13) are in the form of cylinders with rounded bases. A shaft assembly with such devices is also described.
