Abstract

An air jet loom (10, 110) includes a weft insertion nozzle (18, 118) for inserting a weft thread (14, 114) through a shed by means of an airflow; a first supply channel (28, 128) for supplying the weft insertion nozzle with first compressed air for weft insertion; and a second supply channel (30, 130) for supplying the weft insertion nozzle with second compressed air used for threading the weft thread through the weft insertion nozzle and having a pressure different from that of the first compressed air. The second supply channel has an on-off valve (44, 144) for opening and closing the second supply channel. The on-off valve is opened in response to a control signal (S4) from a manual operating device (64). The manual operating device includes an operating switch (66) for outputting the control signal and a setting unit (70) for adjustably setting a time period in which the on-off valve is opened. When the operating switch is operated, the control signal is output to the on-off valve for the time period set by the setting unit.
