Mechanism for controlling the pressure fluid supply to the weft inserting nozzles of a multi-color jet loom

摘要

There is disclosed a mechanism for controlling the pressure fluid supply to the weft inserting nozzles of jet looms provided with a device for color pick changes. The mechanism of the invention is used with a jet loom having a synchronizing pulse generator, the mechanism including a system of two parallel branches each of which comprises a series combination of pulse-shaping circuit, power amplifier, a solenoid-control valve, and a weft inserting nozzle, each of the branches having an input which is connected to a respective one of the outputs of the synchronizing pulse generator.
