  • Patent number: 6164341
    Abstract: In a weaving machine, the shuttles of the weaving machine are transferred over and across the warp threads of the machine. The method and apparatus have the object of preventing factors which adversely affect the weave result from occurring at high shuttle speeds. One or more air or gas streams (flows) are conveyed from the undersides of the warp threads and upwardly via the warp threads to their upper sides. With the upwardly conveyed air or gas stream, each shuttle is given a lifting movement which prevents burn damages, deformations and wearing of the warp threads due to a high shuttle speed.
