Abstract:
A fill yarn holding apparatus for use on an air jet loom of the type used for weaving certain fabric patterns wherein each pattern has at least two fill yarns introduced between each harness reciprocation, and including a pivotal sley shaft, a reed mounted on the sley shaft, at least one air jet main nozzle for propelling fill yarns across the length of the reed, wherein after the reed beats the successive fill yarns against the fell line of the fabric being woven, the harnesses cross to lock in the weave pattern, comprising:(a) at least one holding air nozzle, the holding air nozzle mounted on the sley shaft of the loom; (b) said holding air nozzle having an opening so formed and positioned that, when operated, directs a jet of air against the previously laid fill yarn transversely to the path of the fill and toward the fell line; and (c) wherein when the at least one air jet propels a fill yarn, the holding air nozzle operates at a selected time to discharge air against the fell line to hold the fill yarn in place until the reed beats up to create a uniform weave pattern.
