Fig. 4 describe whether from first jet 33 spray air (ON (opening) or OFF (passs)), if from second nozzle 36 spray
It penetrates air (ON or OFF), draw conditions are usual draw conditions or start draw conditions (draw conditions when yarn is weaved),
Opening/closing portion 73 is to be in closed state in opening-wide state.The horizontal axis of Fig. 4 is the time.Fig. 4 is described in winding operation,
It carries out becoming off-state because of fine sand 10, spinning etc. stops, and carries out cleaning action and connects yarn etc., until starting again at winding operation
Processing process.
In winding operation, in order to usually be spinned, and it is as described above, air is sprayed from first jet 33, but not
Air is sprayed from second nozzle 36.In order to usually be spinned, and drawing-off is carried out under usual draw conditions.Due to suction unit 70
It is lower that the object mainly removed is present in a possibility that near suction port 71, therefore opening/closing portion 73 is in closed state.In this reality
It applies in mode, or save energy spent by the generation for attracting air-flow, and make the opening/closing portion 73 be in winding operation
Closed state makes opening/closing portion 73 in opening-wide state, thus removes Soft flocks in winding operation.
(specifically, producing in the case that fine sand 10 becomes off-state in the winding process for being wrapped 50
In the case where broken yarn, in the case where having cut off fine sand 10 by cutter 24, or stop the spinning of air flow spinning apparatus 9
Only and in the case where having cut off fine sand 10), winding device 26 stops the winding of package 50, and drafting system 7 stops leading for fibre bundle 8
It stretches, air flow spinning apparatus 9 stops spinning.First guiding piece 61 is mobile to the position far from yarn storage device 22.
Later, as shown in figure 5, after the nozzle block 30 for making air flow spinning apparatus 9 is separated with hollow guide shaft body 34, from first
Nozzle 33 sprays air, thus carries out the cleaning action of air flow spinning apparatus 9.It, often can be from gas by carrying out cleaning action
It flows spinning apparatus 9 and flyings is discharged.In order to remove the flyings, and opening/closing portion 73 is switched into opening-wide state from closed state.At this
In embodiment, though simultaneously with the detection of broken yarn and/or the cutting of fine sand 10, opening/closing portion 73 is switched to from closed state unlimited
State, but as long as opening/closing portion 73 is switched to opening-wide state at the beginning of cleaning action.Even if dynamic without cleaning
In the case where work, also at least some period after the stopping of spinning and before the beginning of yarn weaving is formed opening/closing portion 73 spacious
Open state, thus, it is possible to remove the flyings etc. generated at the time point.

At the time of the yarn and thread head of the first yarn can not be captured, which is attracted the attraction of portion 70, and first guide 27 attracts the
The middle part of one yarn can not also capture the first yarn.In other words, opening/closing portion 73 is consistently formed into opening-wide state, thus led
Causing first guide 27 to capture the successful probability of the first yarn reduces.In the present embodiment, at the beginning of yarn is weaved
It carves, opening/closing portion 73 is formed into closed state, after some period of time (for example, rotating upwards in first guide 27
Before), opening/closing portion 73 is switched into opening-wide state.It is successfully general thereby, it is possible to prevent first guide 27 from capturing the first yarn
Rate reduces.At the time of yarn for example refers to the injection air since second nozzle 36 at the beginning of weaving, or starts edge and lead
At the time of stretching direction driving rear roller 16.
Later, after spraying air from first jet 33, first guide 27 keeps attract the state of the first yarn
It rotates upwards, thus the first yarn is guided to yarn splicing device 23 and is able to carry out the position for connecing yarn.As a result, as shown in fig. 7,
One yarn and the second yarn are directed to yarn splicing device 23.In addition, capturing the feelings of the first yarn failure in first guide 27
Under condition, the spinning of the drawing-off and air flow spinning apparatus 9 that make drafting system 7 stops, as shown in figure 8, being attracted simultaneously by suction unit 70
Remove the first yarn that air flow spinning apparatus 9 is sent out.
After the first yarn and the second yarn are directed to yarn splicing device 23, the first guiding piece 61 is to approach yarn storage device 22
Mode it is mobile, thus 61 side of the first guiding piece captures fine sand 10, while by the fine sand 10 to guiding near yarn storage device 22.It
Afterwards, start usually spinning.Specifically, being opened after first guide 27 again and second guide 28 guide yarn and thread head
Begin usually to spin.That is, stopping spraying air from second nozzle 36, and draw conditions are altered to usually from draw conditions are started
Draw conditions.In the change of draw conditions, there is a possibility that generating broken yarn, in order to be easy the attraction in the generation of the broken yarn
Fine sand 10, and at the change moment of draw conditions, make opening/closing portion 73 in opening-wide state.It then, will after the change of draw conditions
Opening/closing portion 73 switches to closed state from opening-wide state.Later, terminate to connect yarn by what yarn splicing device 23 carried out, thus re-start
Wind operation.
