Abstract

A device for the automatic control of the weft yarn feed in air looms comprises at least one sensor (13), which measures the time taken for each yarn turn leaving the feeder (A) to unwind, and an analyzing and monitoring circuit (14), to which are fed the motion analysis signals from the sensor (13) and which continuously monitors the operating times of the solenoid valves (7, 8, 9) - supplying air to the loom nozzles (1, 2, 3) from compressed air receivers (4, 5, 6) - and the air pressure level in said receivers (4, 5, 6).
