Spinning unit described in known Japanese Unexamined Patent Publication 2006-144136 publications.The spinning unit possessed is spinned
Device is to produce turn air-flow by spraying compressed air into spinning room, and spun to being imported into by using turn air-flow
Fibre bundle in yarn room is twisted to generate spun yarn.By the spun yarn that spinning apparatus is spinned by configuring the devices for taking-up in downstream
It is wound up into package.The yarn clearer of the yarn defect of detection spun yarn is configured between spinning apparatus and devices for taking-up.
When detecting yarn defect by yarn clearer, spinning apparatus stops spraying compressed air into spinning room, makes fibre bundle
Twisting stops.The devices for taking-up winding spun yarn in the state of the twisting of fibre bundle stops, thus in spinning room few fibers beam and
The continuous state of spun yarn is truncated.
It is truncated and is wound by devices for taking-up on the loose thread of the spun yarn of side in spinning apparatus, is attached with what is be not twisted
Fibre bundle portion.But the length in the fibre bundle portion to being attached on spun yarn is not controlled.Therefore, according to the fibre of spun yarn loose thread
Tie up the difference of beam minister's degree, it is possible to can not easily pull out loose thread from the package wound by devices for taking-up.

The part section of spinning apparatus known to Fig. 2 expressions；
Fig. 3 represents the top view of spinning apparatus as shown in Figure 2.
Embodiment
Technical scheme is further elaborated with reference to embodiment and accompanying drawing.
Embodiment
A kind of spinning apparatus for possessing jet-propelled spinning machine is present embodiments provided, Fig. 1 represents to be designed as roving spinning machine
Jet-propelled spinning machine a part schematic diagram.On request, roving spinning machine can include draw unit 27, draw unit 27
It is supplied the fiber sliver 3 of such as double stretching sliver form.Also, the roving spinning machine mainly shown is included away from draw unit 27
At least some fibers of the spinning jet nozzle 1 with internal turbulence chamber 5 of certain distance, fiber sliver 3 or fiber sliver 3 are in rapids
Producer twist (the precise manipulation principle that spinning jet nozzle 1 is described in more detail below) is provided in stream chamber 5.
Equally, roving spinning machine can be used for output yarn to 28 and in traction roller including traction roller to 28 downstreams
2 coiler device 29 (equally schematically illustrating).The apparatus according to the invention necessarily needs have drawing as depicted in the figures
Stretch unit 27.Traction roller is to 28 nor absolutely required.
Present roving spinning machine is according to special air-jet spinning technological work.In order to form yarn 2, and by fiber sliver 3
Along conveying direction T spinning spray is fed to via the entrance opening 6 (being preferably designed to separate part) of fiber guide element 18
In the turbulent flow chamber 5 of mouth 1.Here, producer twist is given, i.e. at least some fibers of fiber sliver 3 are sprayed by the air suitably positioned
The air stream of mouth 11 (for example, see Fig. 2) generation is collected.So, some fibre at least slightly pulled out fiber sliver 3 and
Formed wound on the yarn extending into turbulent flow chamber 5 on the end of element 8.
On air nozzle 11, due to simple prevention, point out that these air nozzles 11 should be normal at this point
Ground aligns, to produce air stream along with common direction of rotation identical direction.Preferably, single air nozzle 11 is herein
Arrange relative to each other symmetrical rotary.Also, on shown all exemplary embodiments, it has to be noted that air nozzle 11 exists
There is the flow direction alignd along the direction of wall 12, with the air stream of toilet generation at least substantially with spiral in the case of various
Form yarn formed element 8 outer surface and turbulent flow chamber 5 wall 12 between extend.
Finally, the fiber of fiber sliver 3 forms the inlet port 9 and the quilt of output channel 10 of element 8 from turbulent flow chamber 5 via yarn
Extract out, output channel 10 is arranged in yarn and is formed in element 8 and be connected to inlet port 9.Here, (the ginseng of free-fiber end 30
See Fig. 2) also finally it is pulled on the spiral path in the direction along and into mouth 9, and so stretch yarn core wound on center
Crossed fiber-so as to producing (and the commonly referred to as slub or thick of the yarn with required producer twist is used as on fiber
Yarn).
Due to the only local twist of fiber, so yarn 2 has remaining distortion ability, this in downstream spinning machine for example
Further processing yarn 2 is indispensable in ring spinner.On the other hand, conventional air jet spinning device is to fiber sliver 3
Assign the heavy twist for being no longer able to carry out required distortion after yarn production.This is also desired in this case, because
Conventional sir jet spinning machines is designed as production generally with the famous finished yarn 2 of high intensity.The present invention had both been related to jet-propelled rove and spun
Yarn machine is directed to traditional jet-propelled spinning machine.
The further detail below of spinning jet nozzle 1 as shown in Figure 1 can see that (wherein Fig. 3 is such as Fig. 2 institutes from Fig. 2 and Fig. 3
The top view of the spinning jet nozzle 1 shown).Generally, spinning jet nozzle 1 has the matrix 4 for surrounding turbulent flow chamber 5, and wherein turbulent flow chamber 5 is connected to
The fiber guide passage 7 of fiber guide element 18.Fiber guide passage 7 is used for when fiber sliver 3 is drawn into turbulent flow chamber 5
(air stream that the vacuum wherein needed for this is generated by air nozzle 11 produces) guiding fiber sliver 3.In addition, for this purpose
Not being arranged as the position of the fiber guide passage 7 consistent with output channel 10 prevents producer twist from forming entering for element 8 from yarn
Entrance 9 rises along upstream delivery roller and 20 direction is propagated, because required in region that so can be to entering opening 6
The imparting (or imparting of the twist in the case of conventional jet spinning machine) of producer twist has negative influence.
The sequencing of above example only for ease of describing, does not represent the quality of embodiment.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
