Abstract
A projectile launching and receiving apparatus for a pneumatic loom which includes a bore for receiving the projectile, a pneumatic launching chamber connected to the bore which is pressurized for launching the projectile, a passageway for guiding filling yarn from an outer opening to the bore, and valve means for blocking the passageway between the opening and pressure chamber to prevent filling yarn from being blown toward the outer opening.
Claims9
In a pneumatic loom in which filling picks are inserted from an outside supply source by a pneumatically launched projectile, projectile launching and receiving apparatus comprising:
- (a) a housing having an inner opening at one end, an outer opening at the opposite end, a projectile receiving bore extending axially from the inner opening, a pressure chamber connected to the bore for launching the projectile and an elongated passageway extending from the outer opening to the bore for guiding filling yarn from the outer opening to the projectile receiving bore,
- (b) valve means including a valve element movable from an open position in which the element is clear of the passageway and a closed position in which the element is effective to seal the passageway at a point between the outer opening and pressure chamber, and
- (c) control means for moving the valve element to the closed position during receiving and launching of the projectile.
