Abstract
A weaving device utilizing a projectile and a pressurized medium to guide the projectile as it transports a weft thread from a supply spool through a section of warp threads. A device is also used to introduce and decelerate the projectile. The pressurized medium passes through outlet openings in a plurality of spaced apart guides and moves the projectile by acting upon a plurality of annular recesses on the surface of these projectiles. Further, as the pressurized medium strikes these annular recesses, a pressure build up takes place in the spaces of the annular recesses to create a boundary of air which reduces friction between the projectile and the guides, and which increases the stability of the projectile.
