Abstract
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.
