摘要： Generally, a weft guiding comb for a jet loom constructed in accordance with this invention comprises a root portion, an annular portion integrally connected to the upper end of the root portion and forming an aperture with a slit to allow a weft yarn passed through the aperture to come out of the latter, a fluid passage formed in each of said root and annular portions to allow a flow of fluid to flow therethrough, and a fluid outlet or outlets arranged around the periphery of the aperture for discharging the flow of fluid passed through the fluid passages. The weft guiding comb further comprises a relatively long and narrow fluid path or paths disposed between the fluid passage formed in the annular portion and the fluid outlet or outlets for orienting the flow of fluid, passed through said fluid passage in said annular portion, in a predetermined direction.

摘要： A device for shedding warp yarns in a weaving loom, such as a jet loom, comprises: cranks supported on machine frames of the loom rotatable in synchronization with the weaving operation of the loom; synchronizing levers swingably pivoted; connecting rods connecting the cranks with synchronizing levers so that the rotational movement of the cranks is transmitted as a swinging motion of the synchronizing levers; synchronizing links linked with the synchronizing levers; rocking levers linked with the synchronizing links so that the rotational movement of the cranks is transmitted as a swinging motion of the rocking levers through the swinging motion of the synchronizing levers; and heddle frames, for the upper and lower warp yarns, operated by the rocking levers. The synchronizing levers and synchronizing links are so arranged that, when the connecting rods are located at their dead points which correspond to the uppermost or lowermost position of the heddle frame, one of linking pivots linking synchronizing levers with the synchronizing links is near a line formed by the synchronizing levers and links when they are at their dead points. As a result, the time period wherein the warp yarns serve as upper warp yarns is made different from the time period wherein the warp yarns serve as lower warp yarns, and a difference in tension is created in the upper and lower warp yarns when the beating operation is effected.

摘要： A device for storing a weft yarn for inserting in a jet loom, which is provided with a weft yarn retaining surface, is movable relative to a feed nozzle, for receiving a weft yarn ejected from the feed nozzle. The device is characterized in that a blacking member is arranged in such a manner that one end of the member is engaged with the weft yarn retaining surface at a depositing zone adjacent to the feed nozzle so as to block the fluid from the nozzle as would otherwise disturb the yarn deposited on the retaining surface. A gap is formed between the weft yarn retaining surface and the cover, which gap increases as a position moves away from the depositing zone towards the side where the stored weft yarn is withdrawn.

摘要： The rodless cylinder includes at least a cylinder tube and a piston, but it has no piston rod that is indispensable in the conventional cylinders. The article carrier is connected via the piston yoke to the piston and movable with parts and jigs placed thereon as the piston moves along the cylinder. At least one rod is fixed relative to the cylinder tube to extend in parallel with the direction in which the piston and hence the carrier moves. The sensor is provided to be movable along the rod as the piston moves. The sensor has a moving member movable along the rod as the piston moves within the cylinder tube, for detecting a current position of the piston in accordance with relative positional relation between the moving member and the rod. With such arrangements, the rodless cylinder as a whole has a higher rigidity against heavy load, and also the piston can be accurately positioned to stop at a desired position in its stroke.
