ABSTRACT:
A multi-nozzle weft insertion device which includes a weft guide which uses the hydrodynamic principles of fluid flow around a streamlined object to direct wefts from plural nozzles into a channel which can be centrally located with respect to the nozzles. The wefts are pulled along the contour of the guide, which is streamlined toward the channel, by a flow of high pressure air. The wefts can be kept from becoming entangled by adding a partition wing between the nozzles. If the channel is not centrally located each weft can be made to approach the channel by moving a different distance and from a different angle by varying the shape of the guide associated therewith. Both horizontal and vertical deflection of the weft can be controlled by shape.
