Abstract
A fluid jet loom has a weft inserting nozzle and is equipped with a weft picking control system including means for measuring a weft picking time period for accomplishing a weft picking. The difference between the measured weft picking time period and a standard value in each weft picking is computed, and a plurality of such differences are accumulated to obtain an accumulated value. The accumulated value is compared with an allowable limit to judge as to whether the accumulated value exceeds the allowable limit or not. Upon judgement of the accumulated value exceeding the allowable limit, the air pressure to be supplied to the weft inserting nozzle is controllably changed to regulate the weft picking time period at a suitable value, thereby achieving an optimum weft picking control.
