Abstract
A multi-nozzle weft insertion device is described having a group of independent nozzles, each nozzle corresponding to the weft to be inserted and having a jet orifice, wherein the jet orifices in a bundle point to a weft-path. The device includes a guide tube which has a diameter substantially equal to or somewhat larger than the diameter of the bundle of the jet orifices and is placed opposite the jet orifices; and partitions which extend at least within the inner circumferential area of the guide tube and which are disposed opposite openings formed between the jet orifices, in order to separate the wefts and guide them into the weft-path without contact.
