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.

Abstract: A projectile for use in an outside filling supply loom, comprising an elongated body having an inlet opening at one end and an outlet opening at the opposite end. A flat filling storage chamber is located within the body and is connected to the inlet opening. A passageway located between the storage chamber and outer surface of the body is connected to the outlet opening and the storage chamber.

Abstract: A projectile for use in an outside filling supply loom in which at least a portion of a filling pick is inserted into the projectile prior to each weft insertion. The projectile comprises a weft storage chamber having an inlet opening at one end through which the filling is inserted into the chamber, an outlet opening at the opposite end of the projectile and an air passageway from the storage chamber to the outlet opening which by-passes the filling stored within the chamber so that airflow between the inlet and outlet ends does not affect the filling stored within the chamber.
