  • Nozzle assembly for a weaving machine
    Patent number: 4367772
    Abstract: The nozzle assembly is provided for an air jet loom and includes a guide tube which is displaceable in the direction of the flowing air on the outflow tube of the nozzle. The guide tube allows the gap between the nozzle and the following nozzle or the shed to be adjusted to an optimum value, for example, during a weaving operation. The guide tube allows the weft yarn to be held in the picking line while reducing the tendency of the yarn to be deflected into the surrounding environment.
