Abstract:
An air nozzle weaving loom, having a reed stay which carries a weaving reed and which uniformly swings between a picking position and a beating up position about a longitudinal axis of a driving shaft in order to pick and beat up weft yarns, having a first nozzle arrangement including a plurality of main nozzles having respective main nozzle blow pipes, the main nozzles being positioned in a main nozzle block in a given geometric configuration, and the main nozzle block being fixedly connected with the reed stay, and having a second stationary nozzle arrangement which is situated in front of the first nozzle arrangement in a weft direction and includes a plurality of prenozzles with respective prenozzle blow pipes, a yarn guiding duct of each of said prenozzle blow pipe being aligned in a weft yarn picking position with a respective yarn guiding duct of the main nozzle blow pipe, opposite the respective main nozzle,wherein the prenozzles with the prenozzle blow pipes are positioned in a prenozzle block in a geometric configuration which corresponds to said given geometric configuration of the main nozzles such that an alignment of the yarn guiding duct of a single one of said prenozzles with the yarn guiding duct of a corresponding one of the main nozzles effects an alignment of all of the yarn guiding ducts of the prenozzles with the corresponding main nozzles, the prenozzle block being connected with a weaving loom carrier.
