APPARATUS FOR SHIFTING MAIN NOZZLES ON A FLUID-JET TYPE LOOM

摘要

In an alternate weaving system on a fluid-jet type loom, two or main nozzles for different yarns and combined in a vertically juxtaposed arrangement are driven for common vertical reciprocation in parallel to a vertical plane including the air guide or reed array of the loom for sequential and alternate registration at an operational position corresponding to the entrance to a weft transportation channel formed by the array, thereby allowing an as close as possible location of the main nozzles to the entrance to that fluid ejected by the main nozzles should be wholly caught into the channel for stable weft insertion purposes.
