- An electromagnet controls the selection device and is controlled by a reading device.
- the pivoting selector carries a metal frame, movable in rotation relative to the selector. One end of the armature is permanently near a first pole of the electromagnet, while another end of the armature is movable and can move away from or approach a second pole of the armature. electromagnet according to the power supply of the electromagnet.
- this selection device is cumbersome and complex architecture because it requires the use of an electromagnet and a spring-loaded metal frame which are of significant dimensions. This is disadvantageous because the looms include a relatively large number of these selection devices, to operate each of the levers dobby.
- WO-A-97/32066 discloses a coupling device for a weaving machine.
- a heald frame is hitched to a connecting rod associated with an eccentric mounted around a tree.
- a tilting member and a lever are connected to the eccentric.
- the tilting member and the lever are actuated respectively by a selector.
- the selector is actuated by means of an actuating device.
- this actuating device is formed by a piezoelectric element controlled by a control member.
- the piezoelectric element is engaged with the selector, the latter being fixed to the rocker member.
- One end of the tilting member is directly engaged with a notch of the main shaft of the dobby.
- the piezoelectric elements are fragile elements and this arrangement causes a risk of breakage of the piezoelectric element.
- the end of the piezoelectric element is in direct contact with the selector.
- the deformation of the piezoelectric element is therefore equal to the displacement of the selector.
- the range of movement of the selector is thus limited.

- each heddle frame is raised, lowered or held in position by means of an actuating element of piezoelectric nature whose footprint is low and whose design is simplified.
- the rocker member controls at least one coupling member.
- the piezoelectric element is not in direct interaction with an element which rotates with the main shaft, which makes it possible to limit the risk of breakage of the piezoelectric element.
