The winding drum 10 is supported by an intermediate frame 9 mounted in a pivoting manner at 8 along an axis perpendicular to that of the said drum, so that under the effect of the resisting force exerted on it, the traction cable 17, returned by a self-orientable pulley 5, causes, during its winding, the progressive tilting of the abovementioned frame and the displacement of its periphery with respect to the line X-Y passing through the pulley and perpendicular to the axis of the pivots 8. <IMAGE>
