Abstract (en)

[origin: WO0164986A1] Method and device for controlling a loom, comprising a weaving machine including a shed, through which a yarn is conveyed by means of at least one main weft yarn injector, to which a pressurized medium is supplied, wherein at least the time of arrival of the yarn at the end of the shed is detected, wherein the ideal time of arrival of the yarn end at the end of the shed is determined on the basis of the number of revolutions of the loom, and, upon commencement of the weaving process, the ideal medium pulse that is transmitted to the yarn via the main injector during the initial phase of the weft insertion is determined in such a manner that the yarn end will reach the end of the shed at a specified ideal velocity at the aforesaid ideal point in time, wherein detection of the ideal arrival times associated with a number of positions in the shed takes place at said positions, from which an ideal position-time diagram for the yarn being conveyed through the shed is derived, after which the time of arrival of the yarn end is detected at the aforesaid several positions with each weft insertion during the weaving process, which time is then compared with the ideal arrival times associated with said positions as determined before, after which, if a difference between the measured times and the ideal times is detected, the medium pulse transmitted to the yarn in the main injector is adapted so that the measured differences are entirely or partially eliminated.
