Abstract

A device for driving a primary shaft, the device including: a first system including an element for driving movement of a control member along a looped trajectory having two axial components; a second system including an element for pivoting the shaft about its longitudinal axis, actuated by the movement of the member along at least one component of the looped trajectory; a third system including an element for driving movement of the shaft, actuated by the movement of the control member along at least the other component of the looped trajectory, the control member projecting from the plane of the components and engaged with both the driving element for pivoting and for moving of the shaft, the movement of the control member along the looped trajectory generating a pivoting of the shaft in alternating directions and its movement in alternating directions.
