Jet nozzles of a shuttleless loom are arranged in a vertical tier, which is vertically adjustable to align individual nozzles selectively with the weft picking channel, e.g. for weaving pattern fabric with wefts of different colours. Specifically the array of nozzles is vertically adjustable along a straight-line path by sliding, or along an arcuate path by pivoting, by a push rod actuated by a cam on the loom main shaft and coupled to the push rod by a bifurcated lever with a cam follower. |
