Claims10
A loom, comprising means for forming a warp shed, inserting means mounted at one end of said warp shed for inserting a filling pick into said warp shed, said inserting means including conduit means for holding and conveying a projectile, said conduit means being transferable from a first position to a second position, said conduit means being connected at one of said positions to a source of fluid under pressure, for propelling said projectile through the warp shed, and said conduit means being connected in at least one of said positions to means for disposing filling within said projectile, and further comprising a tubular fluid supply means connected tangentially to said conduit means at a point adjacent the connection to the filling disposing means, whereby fluid under pressure entering said conduit means via said fluid supply means creates a vortex through which said filling must pass prior to disposition in said projectile.
