A device for positioning warp yarns of a weaving loom which are controlled by electrical actuators for forming a shed which includes a first detector common to the warp yarns driven by a plurality of different actuators for detecting the passage of at least one warp yarn into a predetermined position, and a second device for determining a value of a control parameter of an actuator for controlling movement of the at least one warp yarn upon passage into the predetermined position. The process consists in displacing a warp yarn and detecting its passage into a predetermined position and selecting a value of a control parameter of an actuator for the warp yarn upon passage of the warp yarn into the predetermined position and in using the selected value as a control point for controlling an actuator for the warp yarn.
A system for controlling electrical actuators for moving warp yarns in a weaving loom which includes, a first detector means common to, and arranged to detect movement of, a plurality of warp yarns being moved by the actuators for thereby detecting passage of each of the plurality of warp yarns when in a predetermined position, and a second means for determining a value of a control parameter for each of the electrical actuators which control the movement of the plurality of warp yarns upon detection of each of the plurality of warp yarns being in said predetermined position.
