Abstract
A loom is provided with a weft inserting nozzle for picking a weft yarn under the influence of fluid jet and equipped with a weft picking control system which consists of a device for detecting the tension of the picked weft yarn at a timing of termination of travel of the weft yarn in weft picking. The thus detected weft yarn tension is compared with a standard tension by a comparing device forming part of a control circuit thereby to obtain the difference therebetween. The pressure of air to be supplied to the weft inserting nozzle is controlled in accordance with the difference in tension, thus maintaining the weft yarn tension at a constant value.
