Method and device for positioning the warp yarns of a job has a weaving loom and job relates to such a device

摘要

This device for positioning the warp threads (1) of a weaving loom, controlled to the formation of the shed by the actuators (6), comprises a first means (20, 21), common to the threads (1) are driven by actuators (6), for detecting the passage of at least one warp yarn in a predetermined position and a second means (10) for determining the value (theta0) of a parameter (theta) of the control of the corresponding actuator during the passage of a wire position.le in this method consists in displacing a warp yarn (1), to detect (s2) its passage in this position, to select the value of a parameter (theta) for controlling the actuator (6) during the passage of the wire in this position, and to use the selected value (theta0) as a reference value for the control of the actuator.
