) The first locking body (11) and the second locking body (12) that protrude and retract at predetermined timings into the holes (91,001) provided around the hole (91,001) allow one weft insertion before weft insertion. The length is stored separately, and the second locking body (12
) by retracting the guide (13) and the weft gripper (14) while unwinding the accumulated weft (8).
After that, the weft is inserted by the weft insertion nozzle (15). (

も真に適正な付加張力を把握することは困難である。By the way, in the above stationary drum type weft storage device,
At the end of weft insertion, as the length of the weft (8) on the storage drum (5) decreases, the weft should be in a straight line between the first section 11 (11) and the guide (13). (8)
However, due to inertia, an overrun occurs in the W direction in the storage drum (51J), and the weft (8) corresponding to this overrun becomes slack between the storage drum (5) and the guy I" (13), and the weft The tension of (8) disappears, and the first locking body (
11) As a result of the weft yarn (8) wound closer to the tapered portion being pulled back by the pull-out resistance on the yarn supplying body side, the measured yarn length may become shorter, which may cause problems in weaving. As a countermeasure, as shown in Figure 1, a storage drum (
The weft (8) pulled out from the guide (13)
) is attached to the swing shaft (16) next to the lever (
By bending the guide (18) at the tip of the weft (17) after weft insertion, the weft (8) is removed from the storage drum (5).
It is conceivable to prevent the weft yarn (8) from loosening on the storage drum (5) by applying a tension that pulls out the weft yarn (8). However, when tension is applied by mechanically bending the weft (8) as described above (3), it is difficult to adjust the additional tension, and when tension is applied beyond the allowable strength of the weft, a breakage phenomenon occurs. Moreover, this allowable strength differs depending on the weft type, so several trials are required to find the appropriate amount and speed of bending, and even if you do, it is difficult to grasp the truly appropriate added tension. Have difficulty.

製織は困難である。As described above, in the stationary drum type weft storage device, the locking bodies (11) and (12) are protruded and retracted at predetermined timings to intermittently lock the weft (8). The locking bodies (11) and (12) themselves play almost the same role as the weft gripper, and it should be possible to measure, store, and weave the weft yarn even without a weft gripper, but in reality, the weft yarn is oversized. The weft threads become slack due to the run,
It is difficult to weave yarns that cannot be perfectly measured and are prone to fraying, such as filament yarns without fuzz or strong yarns, even if a weft gripper and/or lever for bending the weft yarns is simply provided. be.

による製織方法である。That is, the present invention includes a stationary drum-type weft storage device in which a storage drum is held stationary, and the weft is wound and stored around the surface of the storage drum by a guide that rotates around the surface of the storage drum. When weaving with a piece loom, the present invention is equipped with a drum-type weft storage device of type 112, characterized in that a weft gripper provided between the storage drum and the weft insertion nozzle is opened from weft injection until just before weft cutting. This is a weaving method using a piece loom.

が直線状態になったところで緯入れが終了する。As mentioned above, the weft (8) wound around the storage drum (5) and stored between the first locking body (11) and the second locking body (12) is 12) Due to the retraction operation,
By the jet of water or air from the weft inserting nozzle (15), which starts jetting just before that, the threads are unwound and pulled out from the storage drum (5) and fly through the opening of the warp, just before the end of the flight. The jetting of the weft insertion nozzle (15) is stopped at
Thereafter, the weft runs due to inertia, and (5) weft insertion ends when the weft becomes straight from the first locking body (11) to the guide (13).

生じ、弛みが発生ずる。Even when the weft gripper (14) is provided, the timing of gripping the weft by the weft gripper in the conventional pool pipe type weft storage device is followed as it is, and the weft gripper (14) ) was closed and the weft was gripped. Therefore, due to inertia when the weft (8) is unwound from the storage drum (5), overrun occurs in the weft (8) and slack occurs.

の測長及び緯糸飛走条件を得ることができる。In contrast, in the method of the present invention, the weft gripper (14) is not closed even after the weft has finished flying, but is kept open until just before the reed moves forward and the weft is cut. This is it□
Even if an overrun occurs due to inertia when the weft yarn (8) is unwound from the storage drum (5) after the weft yarn flight is completed,
As the reed moves forward at the same time or after a slight delay, tension is applied to the weft yarn (8) in the direction in which it is drawn out from the storage drum (5) toward the weft insertion nozzle (15), so that no slack occurs. . And like this weft gripper (1
Even if the timing of gripping the weft in step 4) is delayed, the braking action of step (6) by the stopper works, and the overall tension of the weft from the stopper to the edge on the opposite side of the frame is skillfully harmonized with the warp. There is no effect on the intersecting state of . The longer the weft thread gripper (14) is opened, the more effective it is in reducing tension. However, if it is left open even when cutting the weft thread, the repulsive force generated when cutting the weft thread will act to encourage overrun. occurs, which is undesirable, and it is necessary that the weft be closed at the time of cutting the weft. Also weft (
By selecting the closing timing of the weft thread gripper (14) and changing the opening section according to the degree of slack in the weft thread 8), it is possible to select the section where tension is applied by advancing the reed, and achieve optimal length measurement and weft thread skipping. You can obtain the running conditions.

Weft loosening can be more effectively prevented by using in combination with a device that applies bending, l゛ζζ tension, etc. to the weft as shown in 17). The weft gripper (14) usually opens and closes in conjunction with the crankshaft using a cam system, and the timing can be easily adjusted.

できる。As described above, when weaving with a fragment loom equipped with a stationary drum type weft storage (7) retention device, the present invention provides a weft gripper installed between the storage drum and the weft insertion nozzle from the weft injection to just before the weft cutting. It is characterized by being open until the weft yarn has finished flying, so that even if the weft yarn overruns the storage drum after the weft yarn has finished flying, it is possible to apply an appropriate tension and prevent the yarn from becoming slack. , the length of the weft thread can be measured and stored very smoothly, and weaving can be carried out efficiently and smoothly.
