摘要： In a jet weaving loom having a frame, a reed holder pivotally movable relative to the frame in the downstream and upstream directions with respect to the motion of the warp threads, a jet nozzle mounted on the reed holder to move therewith and ejecting the weft thread into the shed of the warp threads by the jet action thereof, and a weft gripper secured to the frame for selectively gripping and releasing the weft thread advancing toward the jet nozzle, so that when the reed holder moves in the downstream direction toward a first extreme position, the beating and the weft cutting are carried out, and when the reed holder moves in the upstream direction and comes to a second extreme position, the weft picking is actually carried out, there is provided a weft pull-back device which catches the weft thread extending between the weft gripper and the jet nozzle when the reed holder is positioned in the vicinity of the first extreme position, and holds the same for a predetermined period of time when the reed holder moves in the upstream direction toward the second extreme position after completing the beating and the weft cutting.

摘要： In a weaving loom including a selvage yarn feeding device usually including a pair of yarn feeding units mounted on and driven by a planetary gear mechanism and each having a yarn guide area in which a selvage yarn being passed therethrough is scraped against various edge portions and thus tend to produce fibrous flues, an apparatus for removing such flues from the yarn guide area of each yarn feeding unit, comprising air-flow inducing means such as flue blow-off means or flue collecting means or a combination of both and valve means which is actuated in cycles synchronized with weaving cycles of the loom so that compressed air is discharged from the flue blow-off means into the yarn guide area and/or suction is developed in the yarn guide area by the flue collecting means whereby the flues deposited in the yarn guide area are splashed therefrom and, if the flue collecting means.
