Abstract: The invention relates to a reel for a winder, comprising: a mandrel (10) extending around an axis of rotation (X) of the reel, a plurality of pairs of lateral arms (20a, 20b) extending on both sides of the mandrel (10), together acting as flanks defining, between them, a winding volume for the link, said reel being characterised in that it comprises a closed flange (40) attached to the arms (20a) constituting one of said flanks, said flange having a thickness of between 10 and 40 mm.

Abstract: A device for winding/unwinding a link includes, but is not limited to, an input shaft and a hollow through output shaft, the two shafts being coaxial and movable in rotation about a longitudinal axis; a permanent magnet synchronous motor comprising a rotor integral in rotation with the input shaft; a cycloidal reducer comprising an eccentric cam mounted integral in rotation with the input shaft, and a cycloidal disc mounted integral in rotation with the cam, in such a way that a rotation of the cam about the longitudinal axis drives a rotation of the cycloidal disc in an eccentric and cycloidal movement; and a transmission member suitable for transmitting an angular displacement of the cycloidal disc to the output shaft.
