By give open end spinning apparatus that the twisting of this fibre bundle generates spinning for known to us to fibre bundle effect turn air stream.
Open end spinning apparatus possesses axle (or hollow guiding axis body).This axle has cylindric or cone shape shape, forms the space (turn chamber) of regulation in the surrounding of this axle.In open end spinning apparatus, the fiber that is subject to the effect of turn air stream is waved in the indoor surrounding in axle of turn.Thus, to fiber twisting, generate spinning.
Like this, because fiber is waved in the surrounding of axle, therefore between axle surface and fiber, produce friction.Therefore, the axle of open end spinning apparatus requires mar proof.In addition, in fiber industry, require the parts of mar proof generally to adopt fine ceramics.Therefore, in open end spinning apparatus in the past, adopted the axle of fine ceramics system.The open end spinning apparatus that possesses the axle of pottery system is for example documented in Japanese kokai publication hei 10-317231 communique.
In recent years, wish more high speed of spinning speed.In open end spinning apparatus, in order to improve spinning speed, have necessity of the turn speed rising that makes the indoor fiber of turn.Therefore, can consider by make the radius of axle diminish (axle is attenuated) the turn radius of fiber is diminished, make the turn speed rising of this fiber.
But the axle that open end spinning apparatus in the past possesses is owing to being pottery system (sintering structure), so toughness is low, fragile.Therefore, suppose if the axle of pottery system is attenuated the worry that has the breakages such as fragmentation and/or crackle to take place frequently in the past.The necessity that has replacing in the situation of axle breakage, becomes the reason that cost increases.Like this, be difficult to make axle in the past thinner, can not fully tackle the such hope of spinning speed high speed.
And, owing to producing friction between fiber and axle, therefore produce static.But, because general pottery is insulator, therefore electric charge can not be bled off, easily charged.On the surface of the axle that the rubbish such as Soft flocks are easily attached to charged, exist to the quality of the spinning generating and bring dysgenic worry.Therefore, have the necessity of carrying out continually the cleaning work of axle in open end spinning apparatus in the past, this cleaning work makes the production efficiency of spinning low.

The specific embodiment
Then, with reference to the accompanying drawings of the fine spining machine (Yarn winding apparatus) of an example of the present invention.A plurality of spinning units 2 and the joint chassis 3 that as the fine spining machine 1 of the Yarn winding apparatus shown in Fig. 1, mainly possess and establish.
As shown in Figure 2, each spinning unit 2 possesses downstream successively from upstream: drafting system 4, open end spinning apparatus 5, yarn monitoring arrangement 6, yarn accumulation device 7 and winder 8.The upstream and downstream of fibre bundle when " ”He“ downstream, upstream " represents spinning in addition, in this manual and the direction of travel of spinning.
Open end spinning apparatus 5 within it portion produces turn air-flow, by making this turn airflow function generate spinning 15 in fibre bundle 10 to these fibre bundle 10 twisting.In addition, the detailed structure aftermentioned of relevant open end spinning apparatus 5.
The spinning 15 that open end spinning apparatus 5 generates is through yarn monitoring arrangement 6.Yarn monitoring arrangement 6 monitors the state of the spinning 15 of walking, and the quality that detects this spinning 15 exists abnormal place (yarn faults).And, in yarn monitoring arrangement 6, set up the cutter 16 in the situation that yarn faults being detected, spinning 15 being cut off.
The spinning 15 of having passed through yarn monitoring arrangement 6 is wound portion 8 and is wound up on bobbin 17.Winder 8 possesses reel cage arm 19, coiling drum 20 and traversing gear 21.
Utilize the spinning unit 2 of above structure to generate spinning 15 and be wound up into bobbin 17 and get on from sliver 9.In addition, spin having reeled the like this bobbin 17 of 15 state is called package.
In the fine spining machine 1 of this example, between yarn monitoring arrangement 6 and winder 8, dispose yarn accumulation device 7.Yarn accumulation device 7 possesses as shown in Figure 2 yarn accumulation roller 23 and rotarilys actuate the motor 25 of this yarn accumulation roller 23.
Each spinning unit 2 possesses unit controls portion 26.Unit controls portion 26 suitably controls the various structures that spinning unit 2 possesses.
Then, with reference to Fig. 3, describe the structure of open end spinning apparatus 5 in detail.The signal longitudinal section of the open end spinning apparatus 5 when Fig. 3 blocks for the plane of the axis with through hollow guiding axis body 32.
As shown in Figure 3, open end spinning apparatus 5 possesses fiber guide assembly (fiber guide portion) 30, nozzle assembly 31, hollow guiding axis body 32 and housing 33.Housing 33 consists of upstream side housing 33aJi downstream housing 33b.
In fiber guide assembly 30, be formed with import drafted device 4 drawing-offs the Conductivity of Fiber hand-hole 34 of fibre bundle 10.Fiber guide assembly 30 keeps being configured in the spicule (fiber guide portion) 44 on the passage of fibre bundle 10.This fiber guide assembly 30 is maintained on upstream side housing 33a.
Hollow guiding axis body 32 has roughly certain cylindrical portion 38 of the tapered portion 37 of side enlarged-diameter downstream and diameter.In tapered portion 37 great footpath one side, make axis as one man be connected with above-mentioned cylindrical portion 38.And, in cylindrical portion 38 and tapered portion 37Zhou center, be formed with fiber channel 39.Thus, hollow guiding axis body 32 becomes hollow form.
The tapered portion 37 of hollow guiding axis body 32 make its path side towards upstream side configure.The cylindrical portion 38 of hollow guiding axis body 32 remains on the housing 33b of downstream.
Upstream-side-end (the path side end of tapered portion 37) opening at hollow guiding axis body 32 has the entrance of fiber channel 39.Guide the upstream-side-end of axis body 32 to be called the inlet portion 40 of fiber channel 39 hollow.As shown in Figure 3, inlet portion 40 configures with spicule 44 top oppositely.Utilize above structure, be imported into the fibre bundle 10 of Conductivity of Fiber hand-hole 34 by fiber guide assembly 30(spicule 44) guide and imported in fiber channels 39 (with reference to Fig. 4) from inlet portion 40.In addition, the end of downstream side of fiber channel 39 becomes diagram abridged outlet opening.
In nozzle assembly 31, be formed with turn chamber 41 and taper chamber 42.Therefore, nozzle assembly 31 also can be called as turn chamber formation parts.Turn chamber 41 forms roughly columned space, is communicated with Conductivity of Fiber hand-hole 34.Taper chamber 42 forms the space of the cone-shaped that side is widened downstream.Taper chamber 42 is positioned at turn Shi41 downstream and is connected with turn chamber 41.This nozzle assembly 31 is maintained on upstream side housing 33a.
Housing 33 can openedly and closedly form.Closing under the state of housing 33 (make the close state of upstream side housing 33aHe downstream housing 33b, be illustrated in Fig. 3) the tapered portion 37 partial insertion turn chambers 41 of hollow guiding axis body 32 and the internally configuration of taper chamber 42.Hollow guiding axis body 32 as one man configures the axis of above-mentioned turn chamber 41 and taper chamber 42.And, closing under the state of housing 33, between the hollow guiding outer peripheral face of axis body 32 and the inner peripheral surface of nozzle assembly 31, form the space (turn chamber 41 and taper chamber 42) of regulation.When generating spinning 15 with open end spinning apparatus 5, become like this state that housing 33 is closed.
By becoming, make housing 33 open modes (make the state of upstream side housing 33aHe downstream housing 33b separation, diagram is omitted), can make nozzle assembly 31 separated with hollow guiding axis body 32 with fiber guide assembly 30.Thus, can make hollow guiding axis body 32 be exposed to outside.The in the situation that of being attached with the rubbish such as Soft flocks on such as hollow guiding axis body 32, by opening as described above housing 33, hollow guiding axis body 32 is exposed, can carry out the cleaning work of this hollow guiding axis body 32.
Surrounding at nozzle assembly 31 is formed with air supply chamber 35.The compressed air supply pipe 36 being connected with diagram abridged compressed air source is connected on upstream side housing 33a.Thus, can to air supply chamber 35, provide compressed air from above-mentioned compressed air source.
On nozzle assembly 31, be formed with the more than one air jetting nozzle 43 that turn chamber 41 is communicated with air supply chamber 35.Air jetting nozzle 43 its length directions overlook towards the roughly tangential direction of turn chamber 41 form.The compressed air that offers air supply chamber 35 is ejected in turn chamber 41 by air jetting nozzle 43.Thus, the turn air-flow flowing around the axis of hollow guiding axis body 32 along a direction turn in the interior generation in turn chamber 41.
Air jetting nozzle 43 as shown in Figure 3 its length direction towards downstream side be formed obliquely a little.Thus, can make the compressed air that sprays from air jetting nozzle 43 side flow towards downstream.
Utilize above structure, the compressed air spraying from air jetting nozzle 43 turn chamber 41 in surrounding's turn of hollow guiding axis body 32 side flow downstream also.Like this, in turn chamber 41, can produce the spiral helicine turn air-flow of side flow towards downstream.
Then with reference to Fig. 4 explanation, generate the appearance of spinning 15 in the open end spinning apparatus 5 of this example fibre bundle 10 twisting.In addition, in Fig. 4, by thick-line arrow, represent the Air Flow in open end spinning apparatus 5.
A part in the fiber comprising in fibre bundle 10 becomes continuum of states between Conductivity of Fiber hand-hole 34 and fiber channel 39.The fiber of this state is called to core fibre 10a.
The free end of upset fiber 10b is subject to the impact at the mobile in the shape of a spiral turn air-flow of the surrounding of hollow guiding axis body 32 in turn chamber 41.Thus, upset fiber 10b as shown in Figure 4 along the surface of the tapered portion 37 of hollow guiding axis body 32 at surrounding's turn of this tapered portion 37.The surrounding that the fiber 10b that overturns is thus wound up into core fibre 10a successively gets on.
Core fibre 10a is by the related twisting of upset fiber 10b of turn.Like this, the surrounding that is wound up into core fibre 10a by upset fiber 10b further twists to core fibre 10a, and above-mentioned upset fiber 10b is twisted in core fibre 10a and generates and spin 15.
In addition, although upstream side (the preliminary roller 14 1 sides) propagation of the sth. made by twisting of core fibre 10a, this propagation is stoped by spicule 44.Like this, spicule 44 has the function that prevents from twisting with the fingers propagation.
Because the spinning 15 generating at open end spinning apparatus 5 is wound portion 8, reel, so the carrying capacity towards downstream is paid in this spinning 15.Thus, spin 15 and core fibre 10a integral body by side downstream, carried.The upset fiber 10b being wound on core fibre 10a is pulled by the related inlet portion 40 from fiber channel 39 of core fibre 10a that side is carried towards downstream the inside that slides into this fiber channel 39.
As described above, owing to guiding the upset fiber 10b of surrounding of the tapered portion 37 of axis body 32 to wave in hollow, so produce friction between the outer surface of tapered portion 37 and upset fiber 10b.But, be not that the whole outer surface of tapered portion 37 produces friction, be mainly in the outer surface of tapered portion 37, the part (part representing with 37a of Fig. 5) near inlet portion 40 produces friction.
As previously mentioned, due to the upstream-side-end of upset fiber 10b from inlet portion 40(hollow guiding axis body 32) towing slides in fiber channel 39, so in the internal face of the end face of this inlet portion 40 and fiber channel 39, the part (part representing with 39a of Fig. 5) near inlet portion 40 produces strong friction.
Therefore, hollow is guided in the surface of axis body 32 especially and produces between fiber friction part 37a, 40 and 39a be called altogether " fiber contact site " (part representing with thick line of Fig. 5).
Feature structure in this example is then described.
The hollow guiding axis body 32 of this example is characterised in that: have the base material portion 50 of stainless steel, be formed with thinly coating (superficial layer 51) on the surface of this base material portion 50.And this example is formed with intermediate layer 52 between base material portion 50 and superficial layer 51.By the structuring concept of the hollow guiding axis body 32 of this example be illustrated in Fig. 6.
In the hollow guiding axis body 32 of this example, superficial layer 51 is as by DLC(diamond-like carbon) coating that forms of tunicle.Due to superficial layer 51(DLC tunicle) as thin as a wafer, so the major part of hollow guiding axis body 32 consists of the base material portion 50 of stainless steel.Because stainless steel has good electric conductivity, so the hollow of this example guiding axis body 32 has good electric conductivity.Therefore, the hollow of this example guiding axis body 32 can easily bleed off the fricative static with fiber.
In addition, keep hollow guiding axis body 32 downstream housing 33b to be formed by the material (being specially metal) with good electric conductivity in order to bleed off the static of hollow guiding axis body 32.And ，Gai downstream housing 33b and the metal framework electrical connection that forms spinning unit 2.This metal framework is grounded.
According to above structure, because hollow guiding axis body 32 is not easy chargedly, so the rubbish such as Soft flocks is not easy to be attached on the surface of this hollow guiding axis body 32.Thus, owing to can always hollow being guided the surface of axis body 32 to maintain clean conditions, therefore can improve the quality of the spinning 15 generating in open end spinning apparatus 5.And owing to can reducing labour and the time of the such maintenance in the surface of cleaning hollow guiding axis body 32, so the production efficiency of spinning unit 2 also improves.
The base material portion 50 that the hollow guiding axis body 32 of this example is stainless steel due to major part, therefore compares toughness with the hollow guiding axis body of pottery system (sintering structure) and increases substantially in the past.Thus, be not easy to produce fragmentation and/or the crackle of hollow guiding axis body 32, can increase the free degree of these hollow guiding axis body 32 shapes.
For example,, in the hollow in the past guiding axis body 132 shown in Fig. 7 A, if make the diameter of tapered portion 37 little, with the thickness attenuation of the direction of the axis direction quadrature of hollow guiding axis body 132.Hollow guiding axis body 132 is in the past owing to being that pottery is made, if therefore thickness attenuation easily produces the breakages such as fragmentation and/or crackle.Therefore, be difficult to make the diameter of hollow guiding axis body 132 in the past to diminish.The hollow guiding axis body 32 of this example of this point is owing to possessing suitable toughness, even if the therefore diameter of tapered portion 37 is diminished (tapered portion 37 is attenuated) thickness attenuation compared with the past as Fig. 7 B is also not easy to produce the breakages such as fragmentation and/or crackle.Like this, axis body 32 is compared with the past can make the diameter of tapered portion 37 diminish (tapered portion 37 is attenuated) for the hollow of this example guiding.Thus, owing to can making the turn radius of fiber diminish, therefore can make the spinning speed of open end spinning apparatus 5 improve.
In the hollow guiding axis body 32 of this example, on the surface of the base material portion 50 of stainless steel, be formed with the superficial layer 51 being formed by DLC tunicle.As is well known, DLC tunicle is compared extreme hardness with stainless steel.Therefore by the surface in base material portion 50, form superficial layer 51(DLC tunicle), can increase substantially the mar proof that hollow guides axis body 32.
From making the mar proof of hollow guiding axis body 32 improve such viewpoint, the part (the fiber contact site shown in Fig. 5) preferably at least contacting at fiber forms superficial layer 51.Hollow guiding axis body 32 part (part representing with 39a of Fig. 5) near inlet portion 40 in whole outer surface (side face of tapered portion 37 and cylindrical portion 38), the end face of inlet portion 40 and the internal face of fiber channel 39 of base material portion 50 of this example is formed with superficial layer 51.In addition, also can on the inner surface of whole fiber channel 39, form superficial layer 51.
Because DLC tunicle is noncrystalline, so flatness rubs well low.Therefore, can reduce the friction between hollow guiding axis body 32 and upset fiber 10b.Therefore, the fiber 10b that can make to overturn, swimmingly at surrounding's turn of hollow guiding axis body 32, can make the turn speed of this upset fiber 10b improve.Like this, according to the hollow guiding axis body 32 of this example, can further improve the spinning speed of open end spinning apparatus 5.
As mentioned above, according to the structure of this example, hollow guiding axis body 32 has mar proof and toughness concurrently, rubs low and has electric conductivity.Thus, compare with the hollow guiding axis body in the past of pottery system, can make the turn speed of fiber improve, spinning speed is improved.
The hollow guiding axis body of fine ceramics system for white in the past or connect subalbous color.Therefore, even if existence is also difficult to the problem of finding that this rubbish is such in the situation that the rubbish such as Soft flocks (being generally white) are attached on hollow guiding axis body.
Because DLC tunicle is generally black, the surface of hollow guiding axis body 32 of therefore having implemented this example of this DLC tunicle is black.Therefore, in the situation that being attached on the hollow guiding axis body 32 of this example, the rubbish such as Soft flocks can easily find this rubbish.Consequently can judge rightly the necessity of the maintenances such as cleaning of hollow guiding axis body 32.Therefore, unnecessary maintenance can be do not carried out, the production efficiency of spinning unit 2 can be improved.
As the method that forms above-mentioned DLC tunicle, can utilize well-known suitable method.But DLC tunicle has the situation with electric conductivity and the situation that there is no electric conductivity according to its formation method.From preventing charged this viewpoint of hollow guiding axis body 32, base material portion 50 not only preferably, superficial layer 51 also has electric conductivity.Therefore, the superficial layer 51 of the hollow of this example guiding axis body 32 is as the DLC tunicle with electric conductivity.Accordingly, because hollow guiding axis body 32 is more difficult charged, therefore can effectively prevent that rubbish is attached on the surface of this hollow guiding axis body 32.
Because the difference in hardness of stainless hardness and DLC tunicle is very large, so the close property of stainless steel and DLC tunicle is low.Therefore, suppose in the situation that the surface of base material portion 50 directly forms DLC tunicle the worry that exists this DLC tunicle to peel off from base material portion 50.This example is provided with for improving the intermediate layer 52 of the close property of base material portion 50 and superficial layer 51 between base material portion 50 and superficial layer 51.
As long as the hardness that intermediate layer 52 has in the middle of the hardness of superficial layer 51 and the hardness of base material portion 50 is just passable.And, if intermediate layer 52 uprise gradually ground multilayer to form from base material portion 50 to superficial layer 51 hardness, be preferably.In this example, intermediate layer 52 consists of thermal treatment layer 53, nitrogen treatment layer 54 and electrodeposited coating 55 successively from base material portion 50 1 sides.
By forming as described above intermediate layer 52, can improve the close property of base material portion 50 and superficial layer 51, can prevent superficial layer 51(DLC tunicle) from base material portion 50, peel off.In addition, because above-mentioned intermediate layer 52 has electric conductivity, therefore can will from this superficial layer 51, be discharged into base material portion 50 by superficial layer 51 and the fricative static of upset fiber 10b.
Surrounding's turn of the hollow guiding axis body 32 of the fiber of effect that as described above, is subject to turn air-flow in open end spinning apparatus 5 in this example.In hollow guiding axis body 32, be formed with fiber channel 39.By above-mentioned turn air-flow, applied the fiber process fiber channel 39 of twisting with the fingers.Hollow guiding axis body 32 possesses on the surface that has the base material portion 50 of electric conductivity and be arranged on base material portion 50, the superficial layer 51 harder than base material portion 50.
Like this, by making base material portion 50 have electric conductivity, hollow guiding axis body 32 is not easy charged.Thus, because rubbish is not easy to be attached on hollow guiding axis body 32, therefore not only can improve the quality of the spinning 15 of open end spinning apparatus 5 generations, and can reduce labour and the time of cleaning hollow guiding axis body 32.Utilization is arranged on the lip-deep superficial layer 51 of base material portion 50, can improve the mar proof of hollow guiding axis body 32.Because base material portion 50 itself does not require mar proof, so base material portion 50 can adopt the material that Toughness Ratio is higher.Thus, owing to being not easy to produce the breakages such as the fragmentation of hollow guiding axis body 32 and/or crackle, so the free degree of these hollow guiding axis body 32 shapes improves.For example,, because the hollow guiding axis body 32(that can more carefully form compared with the past diminishes diameter), therefore can improve the turn speed of fiber, can improve the spinning speed of open end spinning apparatus 5.
In the hollow guiding axis body 32 of this example, superficial layer 51 is diamond-like carbon tunicle.
Thus, can form the superficial layer 51 of enough hardness.And, because diamond-like carbon tunicle coefficient of friction is low, therefore can reduce the friction producing between hollow guiding axis body 32 and fiber.Thus, owing to can further improving the rotary speed of fiber, therefore can further improve the spinning speed of open end spinning apparatus 5.
In the hollow guiding axis body 32 of this example, superficial layer 51 adopts the DLC tunicle with electric conductivity.
By such superficial layer 51, have electric conductivity, because hollow guiding axis body 32 is more difficult charged, so more difficult this hollow that is attached to of rubbish guides on axis body 32.
In the hollow guiding axis body 32 of this example, superficial layer 51 is at least arranged on the part 39a of the inlet portion 40 of fiber channel 39 and the close inlet portion 40 of fiber channel 39 inner peripheral surfaces.
Because the fiber of turn in open end spinning apparatus 5 contact with the above-mentioned position of hollow guiding axis body 32, therefore by superficial layer 51 is set on Gai position, can improve the mar proof that hollow guides axis body 32.
In the hollow guiding axis body 32 of this example, base material portion 50 consists of stainless steel.
The material by such use with electric conductivity forms the base material portion 50 that hollow guides axis body 32, can positively bleed off the fricative static of hollow guiding axis body 32 and fiber.
In the hollow guiding axis body 32 of this example, between superficial layer 51 and base material portion 50, be provided with the intermediate layer 52 that superficial layer 51 and base material portion 50 are close to.
Thus, superficial layer 51 is not easy to peel off from base material portion 50, and the durability of hollow guiding axis body 32 improves.
In the hollow guiding axis body 32 of this example, superficial layer 51 is black.
By making like this surface of hollow guiding axis body 32, be black, observation is attached to the rubbish such as these lip-deep Soft flocks and becomes easy.Accordingly, when maintenance waits, become and easily carry out the cleaning of hollow guiding axis body 32.
The open end spinning apparatus 5 of this example possesses hollow guiding axis body 32, be formed with fiber twist turn chamber 41 nozzle assembly 31 and by fiber guide to the spicule 44 in turn chamber 41.
This open end spinning apparatus 5 is owing to having adopted above-mentioned hollow guiding axis body 32, therefore compared with the pastly can improve spinning speed.
The spinning 15 that the fine spining machine 1 of this example possesses said flow spinning apparatus 5 and this open end spinning apparatus 5 of reeling generates forms the winder 8 of package 18.
This fine spining machine 1 is owing to having adopted said flow spinning apparatus 5, so the formation speed that can improve package 18 compared with the past.
Although preferred example of the present invention has more than been described, said structure can for example change as follows.
The material of base material portion is not limited to stainless steel, so long as it is just passable to possess the material of good electric conductivity.As such material, except stainless steel, can also enumerate such as iron, electric conductivity pottery or superhard alloy (tungsten carbide etc.) etc.But, there is corrosion resistance and possessing in suitable toughness this point, as above-mentioned example, making base material portion 50 is that stainless steel is preferably.
In above-mentioned example, on the whole outer surface of base material portion 50, be formed with superficial layer 51(DLC tunicle).Thus, can improve the mar proof of hollow guiding axis body 32 integral body.But, from this viewpoint of wearing and tearing that prevents that base material portion 50 from causing with contacting of fiber, not necessarily leave no choice but, on the whole outer surface of base material portion 50, superficial layer 51 is set, (the fiber contact site 37a shown in Fig. 5,40 and 39a) formation superficial layer 51 is just passable as long as the part that at least contacts with base material portion 50 at fiber.Due to general DLC tunicle high price, if therefore only form superficial layer 51 at above-mentioned fiber contact site, can seek to reduce the manufacturing cost of hollow guiding axis body 32.
Because intermediate layer 52 is for for improving the layer of base material portion 50 and the close property of superficial layer 51, therefore in the situation that close property between base material portion 50 and superficial layer 51 is enough, also can omit intermediate layer 52.
Equally, in the situation that omit DLC tunicle and the electrodeposited coating 55 of Fig. 6, can grasp nitrogen treatment layer 54 as superficial layer.In addition, because nitrogen treatment layer 54 is compared difference of hardness with DLC tunicle, therefore not talkative mar proof is enough.Therefore,, in the situation that to make superficial layer be nitrogen treatment layer 54, there is the possibility due to friction hollow guiding axis body 32 wearing and tearing with fiber.But in the situation that to make superficial layer be nitrogen treatment layer 54, owing to having omitted the DLC tunicle of high price, therefore having had advantages of, can to form at an easy rate hollow guiding axis body 32 such.Therefore, in the worn out situation of this hollow guiding axis body 32, even if the burden of the hollow more renewing guiding axis body 32 cost aspects is also very little.
Also can omit spicule 44.In this case, the internal face leading edge that fibre bundle 10 limits are formed on the Conductivity of Fiber hand-hole 34 in fiber guide assembly 30 is imported into turn chamber 41.In this case, fiber guide assembly 30 can be grasped as " fiber guide portion " self.
