下する欠点があつた。Problems to be solved by conventional techniques and ideas Conventionally, as disclosed in Japanese Patent Publication No. 57-23020, a nozzle for ejecting pressurized air is made to correspond to the gap between the reed blades, and the airflow causes A pneumatic reed drawing device is known in which the end of the nozzle sucked in from the rear end is blown out from the tip, passed through the gap between the reed blades, and then a door on the side of the nozzle is opened to allow the middle of the warp to escape to the outside. However, with this conventional device, it is necessary to open the nozzle door and release the middle of the warp threads to the outside, which requires a door opening/closing device, which not only complicates the structure, but also takes time to open and close the door. Furthermore, since the door is closed when the warp is fed, if the end of the warp is sucked in from the side, if the warp is stiff, it may end up arching to the suction port. In order to avoid this, it is necessary to insert the warp threads from their tips into the suction port, which has the disadvantage of reducing work efficiency.

供することを目的とする。Purpose of the invention As described above, the reason why the conventional pneumatic reed drawing device has a door at the relief port on the side of the nozzle is that when the air inside the nozzle flows out from the relief port, the tips of the warp threads also escape. This is because it was emitted from the mouth and could not pass through the gaps between the reed feathers.
To provide a pneumatic reed drawing device capable of passing the ends of warp threads between the reed blades without providing a door at a relief port.

できる効果がある。Functions and Effects of the Invention The present invention has the above-mentioned configuration, and the depth from the front surface of the slit groove connecting between the yarn supply port and the yarn outlet of the nozzle body is approximately constant, and the air jet hole is provided in the slit groove. Since the pressurized air is blown downward in a substantially parallel flow from the slit groove, the airflow flowing from the yarn supply port to the yarn outlet in the slit groove becomes a substantially straight laminar flow due to the ejector action, and the air flows through the yarn outlet at the front surface. Since the amount of flow out from the thread supply port is extremely small, the ends of the warp threads supplied to the thread supply port do not escape from the thread release port, and are blown out from the thread blowing port and passed through the gaps between the reed feathers, and then the warp threads are The middle of the thread escapes from the thread release port and the reed threading is completed, and since there is no door in the release port, the structure is simple, the cycle time is short, and work efficiency is high. Even when the warp threads are sucked in from the thread outlet, the tips are sucked into the slit groove while the middle part of the warp threads enter the thread release port, and the threads are blown out through the inner end from the thread outlet into the gap between the reed feathers. It has the effect of being able to be drawn through.

In addition, when the suction hole 18 of the thread suction device 15 is aligned with the gap between the adjacent reed blades b of the reed a,
When pressurized air is supplied to the air supply hole 11 of the nozzle 1, the pressurized air is ejected from the communication hole 10a at the upper end of the ejection hole 10, and a substantially straight laminar air flow flows through the ejection hole 10. Pressurized air is blown downward as a parallel flow mainly in the area on the back end side of the slit groove 5, and due to the ejector action, air is blown from the yarn supply port 6 of the slit groove 5 toward the yarn outlet 7 mainly on the back end side. As the air flows in a straight laminar flow, the air blown into the gap between the reed blades b from the auxiliary jet holes 13 hits the shielding body 20, thereby widening the gap between the reed blades b. When pressurized air flows through the air circulation hole 19 of the suction device 15, the inside of the suction hole 18 is tilted to negative pressure, and in this state, the unwinding end of the warp yarn c wound around the reel 23 is picked by hand and pulled out. , when the air flow passes through the nozzle 1 and is applied from the introduction part 3 to the yarn supply port 6 of the slit groove 5, the air flow flowing through the slit groove 5 from the yarn supply port 6 to the yarn outlet 7 is mainly Since the flow becomes a substantially straight laminar flow on the back end side, and the amount flowing out from the thread escape port 8 on the front side is very small, the warp threads c enter the thread release port 8 in the middle while the unwinding end is slit. The yarn is sucked into the groove 5 and blown out from the yarn outlet 7 into the gap between the reed blades b. At the same time, the yarn is sucked into the suction hole 18 tilted by the negative pressure of the yarn suction device 15, so that it passes along the middle of the warp yarn c. While letting the thread escape out of the nozzle 1 through the thread escape port 8, the unreeled end is drawn through the gap between the reed blades b, and at the same time, the warp thread c is drawn toward the front end side of the gap.

れがない。 As described above, in this embodiment, the air flow mainly flows toward the rear end of the slit groove 5, and the width of the thread escape port 8 is narrowed, so even though the thread release port 8 is not provided with a door. However, the unwinding end of the warp thread c is blown out from the yarn outlet 7 without escaping from the thread escape opening 8. Especially, in the case of a stiff warp thread c, the part of the warp thread c may be unwound while entering the yarn escape opening 8. The ends pass through the inner end of the slit groove 5 and are blown out from the yarn outlet 7, and the warp yarns c are pulled across the upper edge of the door and the edge of the yarn supply opening, as in the case where a door is provided. There is no risk of a situation where suction is not possible due to getting caught.
