Abstract
Apparatus for supplying compressed air to a main blowing nozzle of an airjet loom for filling insertions includes an integrated air feed unit including an intake directly connected to the compressed air supply, an outlet connected to the main blowing nozzle and air flow control valves including valve drivers. Main and bypass ducts provide communication between the intake and the outlet with the airflow control valves controlling the supply of air to the outlet of the air feed unit. The air flow control valves include a check valve arranged to control in an on/off manner the supply of compressed air from the main duct to the outlet; a first adjustable throttling valve arranged to control the pressure of compressed air supplied to the outlet during filling insertions when the check valve is open and a second adjustable throttling valve arranged to control the pressure of compressed air supplied to the outlet between filling insertions when the check valve is closed. A pressure control monitor may be connected to the air feed unit for supplying pressure signals to the loom control system. Individual main nozzles may be provided with respective individual integrated air feed units.
