A hand crank assembly system (50) for spooling linear material onto a reel (60) includes a reel drum (66) onto which the linear material can be spooled and a lever (180) pivotable about an axis (170). A torque transfer mechanism of the system has an engagement clutch that engages and transfers a torque when it is operated in a first rotational direction, but that does not operate nor transfer a torque when it is operated in a second rotational direction opposite the first rotational direction. The torque transfer mechanism converts the pivoting of the lever into the rotation of the reel drum in the first rotational direction regardless of the direction in which the lever is pivoted.

Un système d'ensemble de manivelles (50) destinées à enrouler à la main un matériau linéaire sur une bobine (60) comprend un tambour de bobine (66) sur lequel peut être enroulé le matériau et un levier (180) capable de pivoter autour d'un axe (170). Un mécanisme de transfert de couple du système comprend un embrayage de mise en prise qui se met en prise et transfère un couple lorsqu'il est actionné dans une première direction de rotation mais qui ne fonctionne ni ne transmet de couple lorsqu'il est actionné dans une deuxième direction de rotation, opposée à la première direction de rotation. Le mécanisme de transfert de couple convertit le pivotement du levier en rotation du tambour de bobine dans la première direction de rotation indépendamment de la direction dans laquelle on fait pivoter le levier.
