Multiple color weft insertion divice null of fluid injection

摘要

A multi-nozzle weft insertion device is described having a group of independent nozzles (5 to 8). Each nozzle corresponds to a respective weft to be inserted and has a respective jet orifice (la to ld). The jet orifices are arranged in a bundle so as to point in a weft-insertion direction X. The device further includes a guide tube (3) which has a diameter substantially equal to or somewhat larger than the diameter of the bundle of the jet orifices (la to ld) and is disposed opposite the jet orifices; and partitions (4) 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 in the weft-insertion direction without contact.
