Abstract (en)
A weft yarn tensioning device (40) for an air jet loom (10) includes: a passage forming member (41); an air discharge portion (42); and a shielding member (46) covering a dent gap (S) formed between dents (15) adjacent to each other in a weft insertion direction (X), from a rear surface side of dents (15). In a front view of the air jet loom (10), the shielding member (46) covers at least a part of the dent gap (S) in which a warp yarn (52) is not inserted among dent gaps (S) existing from a downstream side of a weft yarn detection device (20) in the weft insertion direction (X) and from an upstream side of a yarn inlet (44a) of a weft yarn travel passage (44) in the weft insertion direction (X) to the yarn inlet (44a), from the rear surface side of the dents (15).
