Abstract (en)
The apparatus provides for automatically changing the data of various control factors necessary for air injection pressure controlling, which control factors including the sampling number of times at which the leading end of respective insert wefts arrive at the weft detector (6), incremental step for air injection pressure adjustment, allowable minimum and maximum limits of air pressure and other parameters from the trial weaving operation to the actual production weaving operation. With various data of control factors, such as sampling number of arrival times of the leading ends of a plurality of inserted wefts detected by the weft sensor (6) from which an average arrival time is determined, incremental step for air injection pressure adjustment, allowable minimum and maximum limits of air pressure and further parameters stored in the computer control C2, the control factor data for the trial weaving are changed to the control factor data for the production weaving when the loom operation is changed from the trial operation to the production operation, and the values of the air injection pressures detected by the pressure detectors (13, 14) just when the above loom operation change is made, are established as the reference air pressures for the actual production weaving operation. <IMAGE>
