The sIf bundle drafted by the AH is supplied to a binding spinning nozzle in which two air injection nozzles are arranged in series and an air vent is provided between both nozzles. By spinning, the desired bound spinning system was obtained. Air is constantly supplied to such a binding spinning nozzle regardless of whether the draft device is stopped, and the first air injection nozzle of the binding spinning nozzle following the front roller pair
A suction force is created in the yarn passage to suck and introduce the fiber bundle, and at the same time, the second air injection nozzle sucks the fiber bundle that has passed through the first air injection nozzle into the yarn passage, turns it, and forms a bound spun yarn. Form. The opening of the suction duct is exposed to the air vent section provided between the first air injection nozzle and the second air injection nozzle, and fluff and other dust generated within the binding and spinning nozzle are removed by suction. Now, when threading the bundled spinning nozzle having the above configuration, the eastern end of the fiber suctioned and supplied to the first air injection nozzle is
When the air is introduced into the air injection nozzle, the air discharged from the first air injection nozzle collides with the inlet end of the second air injection nozzle in the air vent section, resulting in a diffused turbulence, and the air fluff removal duct facing the air vent section. A phenomenon was observed in which the I fiber side end was not smoothly introduced into the second air injection nozzle due to suction force, etc., and threading failed.

、効率的に糸通しを行うことができた。The present invention will be described in detail below with reference to the drawings. 1 is a back roller pair 2. A drafting device 5 consisting of a middle roller pair 3 and a front roller pair 4 is located adjacent to the drafting device 1, and has a first air injection nozzle 6 and a second air injection nozzle 7 arranged in series, and has both air injection nozzles 6 and 7 arranged in series. A binding spinning nozzle in which an air vent part 8 is provided between the nozzles,
The air vent section 8 is provided with a shutter 9 for opening and closing the opening. 10 is an air pipe for the first air injection nozzle 6, 11 is an air pipe for the second air injection nozzle 7, and 12 is a feed roller for guiding the binding yarn spun from the binding spinning nozzle 5. Reference numeral 13 denotes a suction duct that sucks and removes fluff and dust generated between the front roller pair and the air vent section 8. Next, the threading method of the present invention using the binding spinning device having the above-mentioned configuration will be explained. The fiber bundle S drawn out from a can (not shown) is drafted by the drafting device 1 via the trumpet guide 14, and is supplied to the binding and spinning device 1f5. The fiber bundle S is introduced into the binding spinning nozzle 5 through the first air injection nozzle 6.
The 411 fibers S that have reached the air vent part 8 are introduced into the second air injection nozzle by the air flow introduced through the air pipe 11. A bundled spun yarn Y is formed by the suction force and swirling airflow generated therein, and is wound up as a package on a winding device (not shown) via a feed roller 10. When the spun yarn is being spun in a steady state, the shutter 9 of the air vent section 8 is opened, and the fluff generated between the front roller pair 4 of the drafting device 1 and the air vent section 8 is removed. The dust is removed by suction by the suction air flow of the suction duct 13. However, if the sin bundle S or the yarn Y is cut due to some reason and the yarn is to be threaded through the bundled spinning nozzle 5, the pair of back rollers of the drafting device W11 will stop and the spinning will be interrupted, and the shutter of the air vent section 8 will be closed. 9 is closed, and at the same time, the yarn splicing suction nozzle 15 on the yarn splicing cart (not shown) is rotated to bring its tip close to the outlet side opening of the second air injection nozzle 7, and the operation of the draft device 1 is restarted. In the yarn passages of the first air injection nozzle 6 and the second air injection nozzle 7, there are both the air 111 nozzles 6.7 and the suction nozzle 1 for yarn splicing.
5 works, the first air injection nozzle 6, the air vent part 8. An air stream flowing through the second air injection nozzle 7 is formed, and as a result, a suction force acts on the eastern end of the fiber spun from the draft device M1, and the end of the fiber bundle introduced into the first air injection nozzle 6 The yarn end is smoothly introduced into the yarn passage of the second air injection nozzle 7, and the yarn end is sucked and held in the yarn splicing suction nozzle 15 and transferred to the front surface of the knitter on the yarn splicing carriage. After the yarn splicing is completed, the shutter 9 of the air vent section 8 is opened to remove fluff generated in that section, and the spinning state returns to the normal spinning state. In the embodiment described above, the first air injection nozzle 6 is said to be used to supply air even during thread threading, but the suction force of the second air injection nozzle 7 and the yarn splicing suction nozzle 15 acts sufficiently. When threading, the first air injection nozzle 6
There is no problem even if the air supply is stopped. In addition, the air vent part 8
In order to open and close the shutter 9, a timer (not shown) is activated in response to the restart of the rotation of the back roller pair 2 that has been temporarily stopped due to thread cutting, etc., and the shutter 9 is closed in response to a signal emitted from the timer, and the thread is threaded. The shutter 9 is configured to open after completion. K Effects of the Invention As described in detail above, the threading method for bundle spinning of the present invention comprises a draft device and a bundle spinning nozzle following the draft device, and the bundle spinning nozzle includes a first air injection nozzle and a second air injection nozzle. While being spun in a binding spinning machine that has one injection nozzle in series and an air vent section between both air injection nozzles, the air vent section is equipped with a shutter that can open and close the opening. When a certain fiber bundle is cut,
Immediately stop the back roller pair of the drafting device to interrupt spinning, operate the shutter to close the opening of the air vent, and then restart the operation of the back roller pair to remove the a-leaving edge that is spun through the front roller pair. is conveyed and threaded by the suction air flow that passes through the first air injection nozzle, the air vent section, and the second air injection nozzle of the knot spinning nozzle. The suction force generated in the yarn passage of the first air injection nozzle and the second air injection nozzle and the suction force of the suction nozzle for yarn splicing, which is placed close to the exit side of the second air injection nozzle, are applied to the yarn of the binding and spinning device. By acting on the entire passage, the first air is 11m! ) Forming an air flow passing through the nozzle, the air bleed section, and the second air injection nozzle, so that the end of the fiber bundle is diffused, turbulent, and fluff removed from the air discharged from the first air injection nozzle in the air bleed section. The end of the fiber bundle spun from the front roller pair of the draft device and introduced into the first air injection nozzle is smoothly introduced into the second air injection nozzle without being affected by the suction force of the duct, etc. I was able to thread the thread.
