  • Method of and apparatus for preparing a weft supply in a magazine for weft insertion in shuttleless looms
    Patent number: RE30318
    Abstract: Method of and apparatus for preparing weft supply in a magazine for weft insertion in shuttleless looms, particularly looms with pneumatic or hydraulic weft insertion. The yarn path is prolonged by the action of an air flow in the magazine, into which the weft is continuously fed upon being withdrawn from a supply bobbin. The weft is withdrawn from the magazine in weft inserting intervals in a length sufficient for one pick. The inside of the magazine is constituted to produce a helical air flow which directs the fed weft into a spatial spiral or helox, from which the inserting length is axially withdrawn.
