Description
The present invention relates to a kind of fiber guide element, it for manufacturing the spinning jet nozzle of the sir jet spinning machines that yarn uses from fibre bundle, described fiber guide element has matrix, its outer surface is for the matching surface of the spinning jet nozzle against spinning position, to allow to be fixed on by fiber guide element in the region introducing opening of spinning jet nozzle, and described fiber guide element has inner surface, it can come in contact with fibre bundle during the operation of spinning jet nozzle, and is used for guiding fibre bundle.
There is the sir jet spinning machines of respective fiber induction element and the spinning position equipped with it is commonly known in the art (such as seeing DE4036119C2), and for being manufactured yarn by elongate fibers.The outer fiber of fibre bundle formed at yarn by means of the vortical flow generated by the air nozzle in volute chamber in the region of the aforementioned introducing mouth of element around inner core fiber roll around, and ultimately form the vital winding fiber of the desirable strength for yarn.This generates the yarn with the true twist, and it is finally discharged from volute chamber via extraction channel, and can be wound up on such as reel.
It is said that in general, term " yarn " is for the present invention for representing the fibre bundle that at least some of fiber winds around inner core.Therefore, including the yarn on conventional meaning equally, it such as can be processed into fabric by means of loom.But, the invention still further relates to sir jet spinning machines, so-called rove (also referred to as thick fibre) can be manufactured by means of it.Such yarn is characterised by, although it possesses the intensity being enough to that yarn is delivered to the certain level of follow-up frame, it remains can drawing-off.Therefore rove can be obtained drawing-off by means of drafting system such as drawing frame or by means of the frame such as ring spinner processing rove at it before clearly being spun.
But, independent of the intensity of yarn, it is still desirable to be yarn formed element region in generate the twist will not outwards be propagated through introducing opening in contrast to the direction of the supply of yarn or fibre bundle.In other words, it is necessary to ensure that the fiber of fibre bundle kept their original orientation with vortical flow before contacting, and only obtained the corresponding twist in volute chamber.It is to say, if the twist is propagated in contrast to the direction of the supply, then the associated back rotation of fibre bundle will inevitably lead to fibre bundle drawability in the region of the drafting system of volute chamber upstream.
Although above-mentioned document proposes the pin in the direction pointing to yarn formation element to prevent above-mentioned propagation, it is also known that realized the introducing opening of volute chamber by the opening of so-called fiber guide element, the introducing mouth that this opening forms element relative to yarn is provided with laterally offset.This causes the skew that fibre bundle must pass through before reality manufactures yarn, it is prevented that the twist of fibre bundle is propagated in contrast to the direction of the supply by the friction between fibre bundle and fiber guide element.
Even if being reduced by such scheme and form the danger of the non-required antidromic propagation of the fiber twist of generation in the region of element at yarn, but need nonetheless remain for keeping punching improving the desirable effect of fiber guide element further.
Therefore it is an object of the invention to provide the spinning position of a kind of fiber guide element and associated sir jet spinning machines, in fact fiber guide is improved in present region between delivery roller pair and volute chamber further.
This purpose is achieved by the fiber guide element and spinning position with the feature of independent claims.
According to the present invention, fiber guide element has inner surface, its cross section extended at the central axis being perpendicular to fiber guide element of fiber guide element includes multiple preferably radially inwardly directed protuberance, and at least some of protuberance at least has the profile being inwardly tapered in the proparea of central axis.In other words, fiber guide element has inner surface (it comes in contact with fibre bundle under the installment state of fiber guide element and guides it), and its profile is different from roller tube, and has the elevated regions and depression that cause surface area to increase.Therefore there is inhomogeneities in inner surface, it is when inner surface comes in contact with fibre bundle, causes at least close fiber end joined and guide fiber and the fibre bundle being outwardly oriented.Fibre bundle is without undergoing any radial directed in the known slippery inner surface of prior art, and fibre bundle comes in contact through fiber guide element and protuberance at it, so that the twisted that fibre bundle is in the region of fiber guide element can be almost entirely prevented from.Because protuberance (or at least their overwhelming majority) they towards in the proparea of central axis (namely, extending in farthest region towards central axis) there is the profile being inwardly tapered, so the blocking of fiber or its excessive loads are almost excluded (space that term " introversion " herein refers to the fiber guide element surrounded by protuberance passed through for fiber).
Preferably, described inner surface has tortuous at least in part and/or at least in part in wavy profile in aforementioned cross section.It is easily understood that also possess the inner surface circumferentially closed when the fiber guide element of the present invention is observed in cross section, therefore term " complications " should not be misinterpreted as the part referred to is here straight line.On the contrary, meander-like or wavelike segments such as extend around the internal cavities of fiber guide element with ring style, and itself and then confession fiber or fibre bundle pass through.Inner surface can only be formed by meander-like or wavelike segments.However, it is also contemplated that be that appropriate section occurs alternately, or a part for inner surface is along the profile with roller tube, or such as has ellipse or polygonal shape in aforementioned cross section.
In particular it is advantageous that described profile is formed by swelling, described protuberance extends along the direction of the central axis of fiber guide element in the cross section of fiber guide element.Therefore inner surface such as has star shape in aforementioned cross section, and protuberance can extend in the longitudinal section of fiber guide element on the whole length of fiber guide element or only on certain longitudinal component.In addition, advantageously, all protuberances have along the direction of the central axis of fiber guide element and identical radially extend (alternatively, the degree of radially extending of each protuberance also can be different in size, and increase in the circumferential direction of the fiber guide passage formed by fiber guide element and reduce several times).
It is moreover advantageous that protuberance tapers to a bit along the direction of the central axis of fiber guide element.This causes inwardly directed edge, and it guarantees the particularly reliable radial directed of the fibre bundle to process.These parts tapering to any can be sharp-pointed or rounding, almost independent of its physical characteristic (fiber type, stack length, fibre diameter etc.), can get rid of the damage to fibre bundle in the later case.
Particularly advantageously protuberance is parallel to the central axis extension of fiber guide element.In other words, protuberance upwardly extends in the regulation supplying party of fibre bundle in this case so that its guiding almost only carries out in radial directions.By contrast, fibre bundle stands hardly close to join guiding in its direction of the supply, therefore there is no concern that the negative effect relevant to friction that fiber is carried.Alternatively, protuberance with spiral-shaped extension (central axis relative to fiber guide element), can also can be formed in the region of element along the regulation direction of rotation of fibre bundle at yarn or be wound in opposite direction in this case.
Advantageously, inner surface includes being arranged in the trough in the aforementioned cross section of fiber guide element and crest, and at least some of crest in aforementioned cross section is arranged to than at least one part trough closer to central axis.In this case, protuberance can each have the wall portion of the inner surface limiting fiber guide element, and in this case, two corresponding adjacent wall portion will limit crest, and one of wall portion will limit trough with another adjacent wall portion.Crest and/or trough can taper to a bit (or they equally possible here be rounding).
It is also advantageous that trough and/or crest are formed by the wall portion of the fiber guide element being at least in most of the cases level.In this case, inner surface at least in most of the cases will be formed by above-mentioned wall portion, when it observes in the cross section of fiber guide element, for instance the fiber guide passage being centered around middle part extension extends with meander-shaped.
Particularly advantageously, two corresponding adjacent wall portion angulation α in the cross section of fiber guide element, they are between 10 ° to 70 °, it is preferable that between 20 ° to 60 °, it is particularly preferred between 30 ° to 50 °.Above-mentioned scope refers to angle (α 1) that two adjacent wall portions forming crests are formed each other and the angle (α 2) that two adjacent wall portions forming troughs are formed each other.Additionally, two angles can be equal, it is also possible to be different.Under any circumstance, it is advantageous to two angles are in above-mentioned scope.
Additionally, advantageously, trough and crest have in the aforementioned cross section of fiber guide element that the turning point of turning point, trough and/or crest is each located on circle, oval or polygon particularly has on the polygon of one or more rounded corners that (turning point of trough is defined here as in trough and the distance of central axis is maximum place；The turning point of crest is defined as on crest and the distance of central axis is minimum place).Such as, it is conceivable that above-mentioned protuberance relative to fiber guide element central axis from imaginary circles to extension, and have the maximum interior region to orientation stretching degree also be located at circle on.Similarly, this is equally applicable to such a case, and its medium wave peak and trough are respectively positioned on ellipse or on above-mentioned polygon (such as, triangle or rectangle).
Be extremely advantageous that equally, trough and/or crest circle, ellipse or the polygon limited possesses the central axis on the central axis being positioned at fiber guide element or center of gravity.In this case, fiber guide element such as can have the basic configuration of cylinder, and when observing along the circumferential direction of fiber guide passage, the protuberance of trough and/or crest or formation trough and crest can be configured to be uniformly distributed.This allows fibre bundle to be guided in uniform especially mode, and it reduces the danger of the antidromic propagation of the twist of generation in volute chamber to greatest extent.
It is also advantageous that the diameter D1 that the circle limited by crest (or their turning point) has is 1.0mm～10.0mm, it is preferred to 2.0mm～7.0mm, it is particularly preferred to for 4.0mm～5.0mm.It is also advantageous that the diameter D2 that the circle limited by trough (or their turning point) has is 5mm～15mm, it is preferred to 6mm～12mm, it is particularly preferred to for 7mm～9mm.Above-mentioned scope obtains being suitable for the fiber guide element of overwhelming majority industrial processes fibre bundle.
Additionally, advantageously, trough and crest have turning point in the cross section of fiber guide element, and the turning point of trough is constant to the central axis minimum range of fiber guide element, and/or the turning point of crest is constant to the minimum range of the central axis of fiber guide element.This causes that crest is uniformly distributed in the circumferential direction of inner surface.Turning point (or in the longitudinal section of fiber guide element: bend line) where like being sharp-pointed or rounding.
Additionally, advantageously, fiber guide element is at least had conical butt space at it by extending through of defining of the inwardly directed wall of fiber guide element in the region on front side of at least one of central axis, the lateral surface of truncated cone has at least one exterior contour linearly at least in part in the longitudinal section of fiber guide element.Except above-mentioned frusto-conical shape, space also can have the shape of spherical layer (being also referred to as spherical dishes) so that the lateral surface of truncated cone can have at least one partly convexly or partly exterior contour concavely in the longitudinal section of fiber guide element.Under any circumstance, advantageously, the protuberance in the region being arranged in space extends internally obliquely, thus forming a kind of funnel (namely, in the cross section of fiber guide element, internal diameter changes in the region in space along the longitudinal direction of fiber guide element).
Advantageously, the wall defining described space of fiber guide element is smooth.In this case, can pass through to hole or milling process formation in space.It addition, this causes that fibre bundle gently enters and leaves fiber guide element (under the installment state of fiber guide element, space is configurable on the front side deviating from volute chamber of fiber guide element).
In this context, have plenty of the wall defining described space especially and be transitioned in protuberance so that exist from non-guide wall portion to guiding wall portion and seamlessly transit.Particularly advantageously, in the longitudinal section of the central axis extending through fiber guide element of fiber guide element, the wall angulation β defining space of fiber guide element, they are between 30 ° to 60 °, between 40 ° to 50 °, it is particularly preferred between 42 ° to 48 °.The wall preferably (at least generally) defining described space is axially symmetric or lathe turning relative to the central axis of fiber guide element.
It is also advantageous that fiber guide element at least has maximum outside diameter in the region of one of its front side extending through central axis, it is along the longitudinal direction convergent of fiber guide element.Fiber guide element is therefore such as along direction of the supply convergent in this region.Similarly, corresponding front side can for Frusto-conical in the longitudinal section being parallel to the fiber guide element that central axis extends, and the lateral surface of truncated cone can have at least in part linearly in above-mentioned longitudinal section, partly convexly and/or partly exterior contour concavely.Under any circumstance, it is accomplished that by the external diameter reduced, it is in fiber to be gradually increased with the surface that contacts extending between the protuberance in this region along the direction of bigger external diameter, ensures that fiber smoothly enters or leave fiber guide element (depending on the side at the diameter place of convergent).
Being extremely advantageous that equally, the center of gravity of fiber guide element is positioned on the central axis of fiber guide element.In this case, fiber guide element preferably has axially symmetric design also relative to central axis.By above-mentioned characteristic, it is therefore prevented that installing incorrectly of fiber guide element, because fiber guide element is always to ensure that fibre bundle is guided with uniform radial manner independent of the rotation that is likely to about its center axis.
Particularly advantageously, fiber guide element is embodied as monomer part, because this allows to manufacture in a particularly simple way it.Alternatively, however, fiber guide element can be made up of matrix and insert, and the inner surface of the present invention can be formed by insert.
Extend finally it is advantageous that inner surface is at least in substantially parallel relationship to final central axis.As a result, it is therefore prevented that along the friction of the direction of the supply between fiber guide element and fibre bundle, thus preventing the damage to fibre bundle.In other words, it is advantageous to cross section at least has constant shape on most longitudinal extension degree of fiber guide element.
It is also advantageous that fiber guide element has the center induction element being attached to its matrix or being formed from, it is surrounded by the inner surface of fiber guide element at least in part.Center induction element is therefore in the region that be must flow through by the fibre bundle introducing opening entrance of volute chamber.This causes directly contact between fibre bundle with center induction element, and it ultimately results in the lateral deflection of fiber of fibre bundle, and the longitudinal axis being namely perpendicular to extraction channel deflects.When outside guide portion prevents and forms the antidromic propagation of the twist generated in the region of element at yarn, center induction element ensure that a part of fiber of fibre bundle is forced to and is displaced outwardly, therefore particularly effectively can be taken away by vortical flow, and be wound around around the non-twist fibre bundle core at center.
Advantageously, the induction element at least some parts on the central axis of fiber guide element in center extends, it is ensured that the fibre bundle that induction element is passed through in the mounted state surrounds.
Advantageously, fiber guide element has such as in the one or more guide portion guiding axle or guided plate form, and it starts preferably along the inwardly directed extension of the central axis of fiber guide element from the inner surface of fiber guide element.Although what it turned out provides pointed end to be useful for them for axle, but plate can be rounding on one or more sides, in order to prevents the damage of the fiber to process.Plate is preferably also along extending radially inwardly, and can relative to each other arrange at equal intervals, and/or extends internally from crest and/or trough.
Finally, the spinning position of the present invention is characterised by, its spinning jet nozzle (that is, has the part of volute chamber) and has fiber guide passage along the direction of the supply of fibre bundle in volute chamber upstream, and it is formed by foregoing fiber guide element at least in part.
In this advantageously, the end introducing opening towards extraction channel of center induction element is arranged between introducing mouth and the introducing opening of volute chamber of charging in volute chamber that yarn forms element.It is also advantageous that aforesaid central induction element is farther along the direction ratio aforementioned guide portion extension of the exit opening of extraction channel.It is moreover advantageous that guide portion and/or center induction element extend in extraction channel at least partially.It is also advantageous that minimum range between two guide portion more than corresponding guide portion and center induction element towards the minimum range between the end of extraction channel.Also advantageously, guide portion each has the end of the exit opening towards extraction channel and deviates from the end of exit opening, and an end of the exit opening towards extraction channel of center induction element is arranged between the respective end being in guide portion in the part that the longitudinal axis being parallel to extraction channel extends.Particularly advantageously, center induction element and guide portion each have the end of the exit opening towards extraction channel, and the described end of center induction element is arranged around the described end of center induction element in the part that the longitudinal axis being perpendicular to extraction channel extends.It is also advantageous that minimum range between two guide portion forms in the region introducing mouth of element the diameter less than extraction channel at yarn.Furthermore it is advantageous that the longitudinal axis angulation α of at least one guide portion extraction channel, they are between 10 ° to 50 °, it is preferable that between 20 ° to 40 °, it is particularly preferred between 25 ° to 35 °.It is moreover advantageous that when not having fibre bundle, at least two guide portion contacts each other, and/or at least one guide portion contacts with each other with center induction element.Finally, it is favourable it may be that guide portion and/or center induction element are the parts of the insert obtaining supporting relative to volute chamber in static or moveable mode.
The attendant advantages of the present invention is described in following exemplary embodiment.

Fig. 7-12 illustrates the front view of the fiber guide element of the present invention, and
Figure 13-16 illustrates the different embodiments in (locally) cross section of the spinning position of the present invention.
Fig. 1 illustrates the schematic diagram (it is easily understood that sir jet spinning machines can have multiple spinning position 32, it is preferably arranged to adjacent one another are) in the cross section of the spinning position 32 of sir jet spinning machines.As required, sir jet spinning machines can include drawing frame 27, and it is supplied to fibre bundle 4, and it is such as the form of drafting drawing-off cotton sliver.Additionally, shown spinning position 32 includes spinning jet nozzle 2, it has internal volute chamber 18, and wherein at least some of fiber of fibre bundle 4 or fibre bundle 4 is provided with the twist (the definite working method of spinning position 32 will be described in greater detail below).
It addition, sir jet spinning machines can include a pair involving roller 31 and being arranged in the pair of winding mechanism 29 (schematically showing equally) involving roller 31 downstream, it has the reel 30 for winding the yarn 3 leaving spinning position 32.The spinning position 32 of the present invention not necessarily has drawing frame 27 as shown in Figure 1.The pair of roller 31 that involves neither be indispensable.
Shown spinning position 32 is operated generally in accordance with air-jet spinning method.In order to form yarn 3, in the directed volute chamber 18 entering spinning position 32 via the fiber guide element 1 being provided with introducing opening 8 of fibre bundle 4 (this point also can referring to Figure 13-16).Here give the twist for it, i.e. at least some of air-flow generated by air nozzle 19 of the free-fiber end 28 of fibre bundle 4 introduces, and described air nozzle 19 is properly configured in the spiral wall 20 of volute chamber 18.A part of fiber is drawn at least to a certain extent from fibre bundle 4, and forms the most advanced and sophisticated winding of element 21 around the yarn charged in volute chamber 18.The introducing mouth 22 forming element 21 from volute chamber 18 by yarn due to fibre bundle 4 is drawn via extraction channel 23, free-fiber end 28 (see Fig. 1) is last same along the direction extraction introducing mouth 22, and self is wound around around the core part fiber (so-called winding fiber) of configuration placed in the middle, thus causing yarn 3 to have the required twist.
As general remark, here should be clarified that manufactured yarn 3 can be any fibrous composite in principle, it is characterized in that, the exterior section of fiber (so-called winding fiber) is around the interior section (be preferably non-twist or be similarly sth. made by twisting as required) of fiber, in order to give required intensity for yarn 3.Therefore present invention additionally comprises such a sir jet spinning machines, so-called rove can be manufactured by means of it.Rove is such a yarn 3, it has the winding fiber of relatively low ratio or such a yarn 3, is wherein wound around fiber and is relatively loosely wound around around inner core so that yarn 3 remain can drawing-off.This it is critical that, if manufactured yarn 3 will or must on follow-up frame (such as, ring spinner) drafted to allow the suitable words processed further by means of drawing frame 27.
About air nozzle 19, be only careful for the purpose of, it is also noted herein that be that it should be oriented such that produced air-flow is rectified into generally and is easy to mutually manufacture the parallel airflow with direction of rotation.Preferably, each air nozzle is configured to relative to each other rotationally symmetrical, and tangentially imports (attention, air nozzle 19 does not illustrate in figs. 13-16, in order to become apparent from) in volute chamber 18.
Preferably, from the known spinning position 32 of prior art, also there is the twist holding element inserted such as fiber guide element 1.This can be embodied as pin, it is partly by such as Filament-wound Machine, and prevent fibre bundle 4 along the reverse direction of the supply T twisted in fibre bundle 4 thus along fiber guide element 1 introduce opening 8 direction propagate (this by yarn formation process there is negative effect, because corresponding twisted by again being released after formed the introducing mouth 22 of element 21 by yarn, therefore partly release the twisted applied).
But, because edge 36 shown in Fig. 1 or suitable configuration element placed in the middle can always only from internal action in the fibre bundle 4 around twist holding element, so this effect is limited by it.It addition, fiber generation mechanical load, it stands the lateral deflection can not ignore in the region of twist holding element.
In contrast, the spinning position 32 of the present invention has the fiber guide element 1 of novelty now, it offsets antidromic propagation when the twist is in contrast to the direction of the supply T of fibre bundle 4, and not excessively reduces the required quantity being wound around fiber or cause the non-required mechanical load of fibre bundle 4.
As what find out when can watch Fig. 2-12 together, the figures illustrate multiple embodiments of the fiber guide element 1 of the present invention, fiber guide element 1 is present to be characterised by, the cross section that inner surface 9 is perpendicular to central axis 11 extension at fiber guide element 1 includes several preferably radially inwardly directed protuberance 10, and at least some of protuberance 10 at least has, in the proparea 33 of central axis 11, the profile being inwardly tapered.
The inner surface 9 of fiber guide element 1 such as can have meander-like profile (such as, seeing Fig. 2 and 3) in the cross section of fiber guide element 1.Inner surface 9 is formed by multiple protuberances 10, itself so that limit a succession of trough 12 alternately and crest 13.
Specifically, favourable especially with regard to this point advantageously, the wall portion 14 defining trough 12 and crest 13 of fiber guide element 1 is parallel to the central axis 11 of fiber guide element 1 at least in part and extends, for instance, as shown in Figure 2.Wall portion 14 additionally advantageously defines angle [alpha], and they are between 10 ° to 70 °, it is preferable that between 20 ° to 60 °, it is particularly preferred between 30 ° to 50 °.In this, as can be seen from Figure 7, the described angle (for α 1 in Fig. 7) that can advantageously be arranged in the region of crest 13 about this point is different from the angle (for α 2 in Fig. 7) in the region being arranged in trough 12.It is easily understood that α 1 and α 2 may also be identical.
When fiber guide element 1 fibre bundle 4 its concurrently form the fiber guide passage 24 of spinning position 32 (see Figure 13-16, it illustrates fiber guide element 1 and be in possible installment state, wherein its outer surface 6 is joined or press-fit is against the corresponding matching surface 7 of spinning jet nozzle 2 with close) time, outer fiber parts and aforementioned crest 13 come in contact.This forms one and just connects, and it finally prevents the twist produced in volute chamber 18 of fiber from exceeding fiber guide element 1 in contrast to direction of the supply T propagation.It addition, as shown in FIG., trough 12 and crest 13 can be arranged on the periphery of the preferably fiber guide passage 24 of configuration placed in the middle by distribution mode so that the size of corresponding crest 13 and trough 12 each corresponds to each other.Alternatively, certainly it is also feasible that crest 13 and the trough 12 of fiber guide element 1 are arranged so that its size is change (such as, seeing Fig. 9).
Similarly, the corresponding turning point 25 of inner surface 9 can be (such as the seeing Fig. 3) of horn shape, or is alternatively (such as the seeing Fig. 7 or 11) of rounding.
It is additionally noted that fiber guide element 1 (it is preferably implemented as single parts, and matrix 5 as shown in the figure) not necessarily such as has rounded outer profile as shown in Figure 3 on cross section.On the contrary, cross section for oval (Fig. 8) or polygonal design is also it is contemplated that.Similarly, this is equally applicable to the winding end of crest 13 or trough 12.Here, equally, round-shaped (such as seeing Fig. 3) and different shape such as oval (see Fig. 9) be also it is contemplated that.
Figure 10-12 also show other possible cross sectional shape.As from above-mentioned each figure it can be seen, such as, it is conceivable that trough 12 is partly formed with holes (see Figure 10 and 11).Similarly, trough 12 and/or crest 13 can be flat condition or concavely or convexly rounding (Figure 12).
Finally, it is conceivable that at least one wall 16 in the region being arranged in front side 34 (being arranged in left and right in Fig. 1) of fiber guide element 1 extends into and slopes inwardly, thus obtaining Frusto-conical space 15.If only correspondingly implementing a front side 34, then fiber guide element 1 can be oriented such that (see Figure 13-16) that the direction of volute chamber 18 is pointed in described front side 34 in the mounted state.But, same it is conceivable that fiber guide element 1 is installed in spinning jet nozzle 2 with inverted orientation so that the space 15 formed by fiber guide element 1 is used as a kind of funnel for fibre bundle 4.In addition, also should 30 ° to 60 ° by the angle beta formed around the wall 16 in space 15 and the central axis 11 of fiber guide element 1, between 40 ° to 50 °, particularly preferably between 42 ° to 48 ° (it is also possible that, as required slightly convexly or concavity, they will be located on the surface of such as virtual sphere described wall in this case).
Alternatively, fiber guide element 1 at least can also have the cross section outwards arched upward in the region of one of front side 34, for instance illustrates in figs. 5 and 6, and it causes the outer diameter D 3 of fiber guide element 1, and it is preferably along the direction of the supply T convergent provided of yarn 3.Its cross section can along the basic configuration with such as truncated cone, and the lateral surface 35 that it is outwardly oriented can have the exterior contour of convex (Fig. 5), concavity (Fig. 6) or linearity (not shown) in the side view being shown respectively.
Finally, such as what can be seen that from the contrast of Figure 13 (it such as illustrates that fiber guide element shown in Fig. 21 is in installed state in spinning jet nozzle 2) Yu Figure 14-16, finally favourable can be additionally be equipped with one or more spaced apart guide portion 17 (being such as four in Figure 15 and 16) for fiber guide element 1, and its mutual spacing reduces (at least in cross section) along the direction of the supply T of fibre bundle 4.In other words, spinning position 32 has several element, and it acts on fibre bundle 4 from outside, and closer to each other along the direction of the supply T of fibre bundle 4.Therefore fibre bundle 4 inevitably comes in contact with guide portion 17, and is taken away from outside by them in a sense, so that its twisted in the region of guide portion 17 is prevented further.
But, despite the presence of the fiber guide acted on from outside, local detachment in order to ensure outside fiber end 28 is feasible, a kind of measure that also can carry out is to make guide structure also include at least one center induction element 26 (see Figure 16), and it is such as extending between guide portion 17 in the cross section that the central axis being perpendicular to fiber guide element 1 extends.Although guided outside portion 17 and protuberance 10 " from outside " guide fibre bundle 4, and center induction element 26 is be positioned at fibre bundle 4 " " during the manufacture of yarn, therefore causes that it presses off.In other words, fiber is deflected outward by by center induction element 26, or with geometric terminology, is perpendicular to the central axis 11 of fiber guide element 1.As a result, free-fiber end 28 is also outwards pressed gradually, so that despite the presence of guided outside portion 17 and protuberance 10, also ensure that fiber arrives the region of the air-flow produced by air nozzle 19, and can be wound around around fiber core.
Although guide portion 17 (its preferably about the central axis 11 of fiber guide element 1 and/or center induction element 26 equably and equidistantly configuration) and center induction element 26 all can be placed in outside yarn forms element 21, it is however also conceivable that be guide portion 17 or center induction element 26 extends to (not shown) in the extraction channel 23 of yarn formation element 21.

The shape of guide portion 17 and orientation are also not limited to an embodiment in principle.Such as, it is conceivable that replace the bar-shaped guide portion 17 shown in Figure 15 to use from the direction of the inner surface 9 of fiber guide element 1 axle line 11 wherein prominent guided plate, this also will prevent the twist of fibre bundle 4 in contrast to direction of the supply T antidromic propagation.
About shown guiding axle, it should also be noted that, they should preferably and the central axis 11 angulation δ of fiber guide element 1 (described angle only implies in fig .15 to some extent, with for clarity sake), they are between 10 ° to 50 °, between 20 ° to 40 °, it is particularly preferred between 25 ° to 35 °.
Generally speaking, it can also be advantageous for center induction element 26 in Figure 14 and 16 towards yarn formed element 21 end be located parallel to fiber guide element 1 central axis 11 extend the part between the respective destinations region of guide portion 17 on.This ensures that, fibre bundle 4 at least to contact with guide portion 17 and center induction element 26 at some parts simultaneously.
Additionally, it should be pointed out here that, center induction element 26 should at least extend in the region that it is inwardly directed on the central axis 11 of fiber guide element 1, and the central axis 11 of fiber guide element 1 can configure collinearly with the central axis 11 introducing opening 8.The center of fibre bundle 4 therefore center of impact induction element 26, is correspondingly laterally deflected, because it must flow through center induction element 26.
As shown in figures 13-16, guide portion 17 and/or center induction element 26 such as can form the direction orientation of element 21 or a part for fiber guide element 1 from inwall to yarn.Alternatively, however, it is also possible to guide portion 17 and/or center induction element 26 are fixed other local.It is, for example possible to use insert (being such as embodied as sleeve), it includes guide portion 17 and/or center induction element 26, or is attached to described parts.This insert is installed together with fiber guide element 1 the most at last in the region introducing opening 8 of spinning jet nozzle 2, so that fiber guide passage 24 will be formed by two parts (it is easily understood that, guide portion 17 and/or center induction element 26 can also be directly anchored on spiral wall 20 so that fiber guide element 1 will only have aforementioned protuberance 10).
