Abstract (en)
A warp bending device (20) is included in a loom that includes a dropper-type warp breakage detection device (6) disposed on a warp-let-off side of heald frames and which is set such that a time at which warp yarns (1), which are caused to perform a shedding motion by the heald frames, are set to a shed closed state differs from a beating time at which a weft yarn is beaten against a cloth fell by a reed. The warp bending device (20) includes a warp bending member (30) that is disposed between the dropper-type warp breakage detection device (6) and the heald frames in a warp direction and above or below a row of the warp yarns (1) in a vertical direction and that extends over a region of the row of the warp yarns (1) in a weaving-width direction, the warp bending member (30) being positioned such that the warp bending member (30) is in contact with one of an upper warp yarn row and a lower warp yarn row of the warp yarns (1) that are in a shed open state and bends a path of the one of the upper and lower warp yarn rows at least at the beating time.
