<p>The device (1) has a deviation stop (4) fixed to a curved guide track (3) that is displaced along a radial axis of a circular piece (2) and fixed at a given location along the axis. The stop and the track constitutes mechanical units guiding and sliding an elastic belt towards a pulley. The mechanical units are adjustable and are integrated to the circular piece moved in rotation. The stop has a width lesser than that of the track such that a minimal width of the track at the level of the stop is equal to a width of the belt.</p> |
