Abstract: A mechanical winding device for obtaining complex movements comprises a first means for causing movement from one point whose projection on a given axis is a sinusoidal movement with respect to time at a determined frequency. A second means causes the movement of the first means in such a way that the projection of the point of movement along a given axis is the algebraic sum of a sinusoidal movement in respect to time at a determined frequency and of a sinusoidal movement in respect to time at a frequency three times that of the previously determined frequency. Receptor means for the movement is also obtained.
