Suction element in the spinning district
In Fig. 2 and Fig. 3, in mode diagrammatically, at length shown suction element.It comprises the shell 37.1 as passage, and passage leads to aspirator 4 always, and aspirator is commonly called suction system as continuous extension in fine spining machine, utilizes this system, emits suction air.In the front portion of shell 37.1, guide plate 44b, 44c are installed on the tongue 44a.Utilize tongue, plug-in unit 37.2 and 37.3 can be fixed.Yet the shell 37.1 that guide plate 44b and 44c are housed also can design by this way, and promptly it only has a plug-in unit 37.2.In this case, guide plate 44b needn't be installed.Plug-in unit 37.2 and 37.3 inserts in the shells 37.1, because plug-in unit as shown in Figure 2 37.2 is on the installation site, its arrow A between guide plate 44b and 44c has been lowered the position, and is parallel to the axle of guide plate 44c then, oppositely mobile to arrow.
Preventing that facing to the boss 49 on the side of the plug-in unit 37.2 of shell 37.1 plug-in unit 37.2 is pushed as far as by guide plate 42, no longer provide the undefined position of guide plate 42, the outside of boss 49 is against guide plate 42, therefore boss 49 and guide plate 42 have been guaranteed the relation of plug-in unit 37.2 itself and shell 37.1 together, by at first on the direction of arrow A, make plug-in unit 37.3 near tongue 44a, be supported on the described tongue, plug-in unit 37.3 is installed equally up to it.Therefore, plug-in unit moves right on the direction opposite with arrow b, by the slit between guide plate 44b and the tongue, up to the boss (not shown) against guide plate 44b.Behind pack into plug-in unit 37.2 and/or 37.3, mobile around the cover 37.4 of the axle A rotation of shell 37.1 according to being directed downwards of arrow C, be supported on the tongue 44a up to the base of this cover (bottom).In order to absorb air from plug-in unit 37.2 and/or 37.3, each housing opens wide in the side facing to plug-in unit 37.2 and/or 37.3.Utilize the blower fan (not shown) to stitch 41 by the suction seam 40 of plug-in unit 37.2 and/or the suction of plug-in unit 37.3 by the air that aspirator 4 imports, at first enter the inside of each plug-in unit according to the direction of arrow d, according to arrow e, the direction of f flows, and enters in the cover 37.4 as passage then.The air-flow that flows into plug-in unit 37.2 passes the opening 45 of described plug-in unit one side, flows through cover and/or passage 37.4, and according to the direction of arrow g, continues across the 3rd opening 48, enters shell 37.1.When cover 37.4 is closed, in first opening 45 on the plug-in unit 37.2 and second opening 46 on passage 37.4 layout that is in line.In addition, if cover 37.4 closures, the 4th opening 48 on the shell 37.1 is in alignment with the 3rd opening 47 on passage 37.4 rear sides.The element that suction element 37 comprises is shell 37.1 and plug-in unit 37.2, if necessary, also comprises plug-in unit 37.3 and cover 37.4, and suction element can be used as an integral body packs in the machine, perhaps installs as single part.Yet, also may only change plug-in unit 37.2 and/or 37.3 according to processed material.According to the mach fibrous material of spun yarn, the slit on plug-in unit 37.2 and/or 37.3 40 and/or 41 can be designed to different profiles and different slits, when fine spining machine is produced another kind of material, just can select the optimal shape of slit.Right half of at Fig. 2, with the part that dotted line has drawn afterturn element 31, described element is cylindrical or non-cylindrical solid and/or bendable cylinder or a little band or a fabric strip.At least on the part of afterturn element 31, the afterturn element is contained in the top of inhaling seam 40,41, on the afterturn element 31 perforation is arranged, and enters in order to allow air pass and inhales seam, and allow rove 71 through the afterturn element 31 in slit 41 zones shown in Figure 1.Obviously, above another plug-in unit 37.2, under the mounting condition of shell 37.1, also can provide the another kind of corresponding design (not shown) of afterturn element 31.Can find out that from Fig. 3 only the part of afterturn element 31 is alignd with shell 37.1.As shown in Figure 1, if afterturn element 31 is fixedlyed connected (not rotating) with roller 11c arranged concentric and with described roller, shell 37.1 just is suitable for being contained on the roller 11c so, directly supports or utilizes spring 11d to support.The latter can guarantee plug-in unit 37.3 or 37.2 freely contact on each corresponding afterturn element 31.If afterturn element 31 is a piece of tape or a little fabric strip, afterturn element and roller 11c do not lock on direction of rotation so, and in this case, roller 11c just has the function of supporting housing 37.1.In the zone of plug-in unit 37.2 or 37.1, brake roller 35 can be contained on the afterturn element 31.This roller on the direction of transfer of rove 71 as a drive unit of afterturn element.By afterturn element 31 and/or be close to the installation of the afterturn element of shell 37.1, just finished the assembling of shell 37.1 and plug-in unit 37.2 and 37.3 in the operating process of fine spining machine.Therefore when the afterturn element moved with respect to shell 37.1, the afterturn element just moved with respect to plug-in unit 37.2 and 37.3.Opposite with plug-in unit 37.2 and/or 37.3 shown in Figure 2, plug-in unit be shaped as arch, its inside and outside profile is closer to each other, in an embodiment, its inside and outside profile is essentially concentric circles.If afterturn element 31 is flat in plug-in area, the one side that has the plug-in unit 37.2 of slit 40 so must be flat, makes slit be located immediately under the perforation of afterturn element.
In having the fine spining machine of drafting unit, the twisting unit of rove and spinning apparatus, several this devices in turn are arranged in the fine spining machine, and this fine spining machine has the afterturn element in twisting unit, therefore the fixedly suction element of aspirator is assigned in the afterturn element, the air of discharge is entered in the suction element of the present invention by the afterturn element, and suction element becomes point-like ground and/or links to each other with relevant support component in supporting base floating.Suction element on the afterturn element is allocation really, with respect to the afterturn element at least gapped and/or determine in the radial direction by the axle that makes afterturn element rotation.Supporting base designs by this way, compensates in the support of supporting base and the tolerance between the afterturn element elasticity by supporting base.
As shown in Figure 4, the basic element of character of twisting unit is simplified, and described parts are described in detail in Fig. 2, and that describes in Fig. 2 has a shell 37.1, and the suction element 37 of plug-in unit 37.2 grades only is to represent in the arcuate arc of afterturn element 31 in Fig. 4.According to embodiment shown in Figure 4, the inside of suction element 37 is positioned on the 11c, with its outside against afterturn element 31, afterturn element shown here is the columniform cylinder of a porous, therefore control suction element between rotating cylinder 31 and axle 11c, axle 11c is fixedlyed connected with described cylinder, therefore, stay pipe 402 links to each other with suction element 37, to discharge suction air.Below afterturn element 31, an other suction tube 408 is arranged, its opening is near the bite between afterturn element 31 and the brake roller 35.Air not only flows into suction element but also flow out from suction element, and a part flows through stay pipe 402, and another part enters suction tube 408, shown in the thick arrow of figure.Air-flow is again by pipe admission passage 406, passage 406 fine spining machine vertically on install and link to each other with a main air blower.Between stay pipe 402 and an intermediate tube 404 that further extends a supporting base 414 is arranged, this supporting base is placed in the slit 410 ' of bearing 410.In the corresponding position of supporting base 414, comprise a narrower part 414 '.Supporting base 414 preferably is designed to turn round the caoutchouc elasticity part of symmetry, particularly in the left field of as shown in Figure 4 narrower part 414 ', all has higher elasticity at the vertical and horizontal of stay pipe 402.Corresponding to supporting base 414, enter into passage 406 places at intervalve 404 ends second supporting base 416 also can be installed.There is the support 410 of point image passage 406 to link to each other with the framework 412 of fine spining machine.Bearing 410 the bottom, as shown in Figure 4, the guide groove 410 of a conducting suction tube 408 is arranged ".
Referring to Fig. 4 a, are heads 402 ' at the right-hand member of stay pipe 402, it is used for stay pipe 402 is contained in suction element 37, head 402 ' is placed into the passage 414 of supporting base 414 " in.Head 402 ' is slightly greater than the diameter of stay pipe 402, it is positioned at the terminal of stay pipe, after installation, enter the groove 414 of supporting base 414 " in; as being mentioned in the layout description of Fig. 4; in most preferred embodiment, the shell 37.1 of suction element 37 is between two afterturn elements 31.Yet suction element 37 and/or shell 37 can not overlap yet, and promptly move near axial single cylinder and/or afterturn element 31.Shell 37.1 will be transferred on the stay pipe 402 and with it and be rigidly connected, and the supporting base 414 of at first will packing under the situation of no plug-in unit 37.2 and 37.3, is linked shell 37 on the fine spining machine.The operator must only fit together shell 37.1 and stay pipe 402 for this reason, puts into supporting base 414.Be placed on the second narrower part 414.2 of supporting base 414 at first axial stop 418 of the left supporting base portion 414 ' of supporting base 414 " in; if the head 402 ' of stay pipe 402 is placed into passage 414 ", block 418 stops flexible supporting base element 414 to move right again.Therefore position shown in Figure 4 has provided suction element 37 positions and/or the position of the stay pipe 402 that links to each other with suction element roughly, reach the position of head 402 ' in supporting base part 414 ', when in one way with the accurate centering of afterturn element 31, suction plug-in unit 37.2 or 37.3 is directed between the inner surface of a 11c and afterturn element 31 in the space.
If, can accumulate floating thing owing between suction element 37 and afterturn element 31 inside, place, gap radially can narrow down, if and the friction that produces between suction element and afterturn element and/or axle 11c is too big, so, exercise it by anticlockwise afterturn element 31 subsequently and go up stretching, extension and have the suction element 37 of stay pipe 402 to turn to, this can be realized by the flexible design of the left side supporting base part 414 ' of supporting base 414 at least.Therefore, as shown in Figure 4, on the left side of supporting base 414, can close switch 424, in the circuit 428 between switch or common described switch, sensor 42 and rove stop 424, trigger solenoid, make clamping head under the effect of electric current, shift to the stop of material conveying device 71.Therefore stoped material to drafting unit, to 11a, the 11b representative is supplied with, and can not sent into the yarn of yarn that fault is arranged or not afterturn in the production thus by roller for it.The interruption that material is supplied with can be by showing by checkout gear and/or display 426.If because the frictional force on the afterturn element 31 makes that the pulling force on the suction element 37 is too big, so can be with the groove 414 of stay pipe 402 from supporting base part 414 ' " pull out, the suction on suction element and/or afterturn element 31 surfaces no longer increases.In this case, on the excircle of afterturn element 31, the fiber of material transport device 71 has caused the interruption of fibre stream no longer by enough guiding, makes described fibre stream be removed by suction tube 408, and no longer enters in the spinning apparatus shown in Figure 15.Therefore do not have switch 422 and/or thin slice stop 424, but also interrupt flow flows to the material of spinning apparatus, and can not send in the product by vicious afterturn yarn.This switch is designed to the switch of limit switch or contactless type.
Referring to Fig. 4 b, second block 420 is positioned on the bearing 410 on first block, 418 next doors of having described.It prevents that supporting base 414 is pushed outwards in the horizontal mobile journey of stay pipe 402.Measure between block 418 and 420 to second narrower part axially and radial distance and/or measure block 418 and 420 with respect to supporting base part 414.2 ', at the stay pipe 402 that the prolongs axial and radial distance on the vertical direction longitudinally, in order to compensate bearing 410 and in afterturn element 31, to aspirate the tolerance of allowing between the position of plug-in unit 37, not considering to have between them under the situation of very big frictional force in advance, concerning supporting base 414 and/or left supporting base 414 ', must provide the gap.
The adjusting of suction areas
In order to make whole suction system be in optimum state, on suction plug-in unit 37.2 and/or parts relevant and suction tube 408, have hole 430 and/or 431 with the suction plug-in unit, can on different pumping parts, adopt suction operation so as requested.According to Fig. 5, hole 430 and/or 431 can be passed flexible supporting base element 414 and/or pass suction tube, and hole 432 also can be passed from the transition piece 416 of chamber 416 ' admission passage 406 ".As seen from Figure 5, compare with Fig. 4, the not direct admission passage 406 of stay pipe 402 and suction tube 408, but enter the chamber 416 ' that links to each other with passage 406.Suction tube 408 and/or stay pipe 402 that number is limited can import chamber 416 ', and for example 12 every on such pipes all import chamber 416 '.Hole 430,431 and 432 can be used respectively, also can use together.Insert transition piece 416 if having only a hole 432 " and/or use special transition piece 416 ", obtain suction operation in each spinning district and be more prone to.By this way, some districts of fine spining machine can be adjusted to and be different from other district, in other district, produce other yarn with different suction performance.Can as can be seen from Figure 4 between suction element 37 and passage 406, be connected with pipe and/or flexible pipe 402.In this case, stay pipe 402 is not to be designed to the air translator unit, but therefore a pipe is the bracing or strutting arrangement as suction element 37.If use pipe or flexible pipe 402a, can save from the intermediate tube 404 of supporting base 414 to second supporting bases 416.Pipe and/or flexible pipe are designed to flexible, make stay pipe 402 unrestricted with respect to relatively moving of supporting base 414.
Fig. 6 has schematically shown importing transition piece 416 " the part of passage 406.Shown in the arrow of Fig. 6, the purpose of this transition piece is: postpone the air-flow of passage 406 inlets, make air flow divert simultaneously, therefore farthest avoided producing eddy current in passage 406.Transition piece 416 " be considered to the shell of a truncated cone, cross section has the point image ellipse, and tilts to axle A.Referring to Fig. 6, the axle A of the truncated cone forwards the curve arrow of bottom right to from upper left straight arrow, and it acutangulates with respect to the main flow direction of passage 406, imports air-flow from the top down.Fig. 6 is the floor map with top Fig. 5 relevant portion.
The speech relevant with 432 with label 430,431 " hole " in general is the part of hollow with conducting air of a certain internal diameter.Therefore the internal diameter in hole according to the hole in the position of fine spining machine and different.
Can find out further from Fig. 6: the end of passage 406, promptly the bottom links to each other with the assist gas pressure source.Blower fan makes air-flow pass transition piece 416 " admission passage 406.
As shown in Figure 6, a sensor 438 can be contained in the porch of the passage 406 that links to each other with checkout gear 436, and the assist gas pressure in passage 406 is by checkout gear 436 controls.Be lower than in assist gas pressure under 50 to 60mm the situation, just represent that blower fan 434 fault occurred or worked undesiredly, sensor 438 transmits a signal by checkout gear 436 then, and by control device whole fine spining machine is quit work.
Except the width of slit, distance that the roller that provides among Fig. 5 is 35 and/or the determined afterturn distance of length of inhaling seam 40 in suction plug-in unit 37.2 work, make the consumption of air and/or in passage 406 stroke of assist gas pressure reach desired level.
Fig. 7 has shown the tonogram in the passage 406 qualitatively.In the aux. pressure maximum of the input of blower fan 434, and descend continuously, can derive from the arch branch of the curve of Fig. 7 along the direction that is positioned at passage initial point top.Minimum aux. pressure above above-mentioned point equals as 100mmWs (water column), and at the inlet end of blower fan, minimum aux. pressure can reach 200 to 250Ws (water columns).In addition, the left side in the arch branch of curve in Fig. 7 is a straight line, and it has represented transition piece 416 qualitatively " the tonogram of inlet end.At transition piece 416 " in different macropore and/or different internal diameter or the different passwaies of transition piece of transition piece, can make strong different pressure is that airflow direction enters chamber 416 ' zone and/or pipe 402 and 408 discontinuously along passage 406.The pressure of Fig. 7 cathetus stroke falls, and in other words, aux. pressure P strides across the stroke of length L of passage 406 in the variation of the entrance point of passage 406, for example, becomes 100mmWs at the inlet end that enters blower fan 434 from 80mm.In addition in Fig. 7, drawn the P1 tonogram of passage 406 and the P2 tonogram in spun yarn district, the difference that subtracts P2 because of. this P1 is equivalent to the tonogram of hole 430,431 or 432.
The optimization of suction system
When making has the distribution of suction system of fine spining machine of twisting unit, in general, pay special attention to air consumption.Because be the total sizable part of operating cost at the cotton mill energy cost.Because, in a fine spining machine, there be more than 1000 spinning district that suction air will be provided usually, also be like this on careless woollen frame, as shown in the figure, at at least two points, air is sopped up, if it is to be large enough to remove suction air along machine that a passage is only arranged, the cross section of passage 406 must be designed to the cross section greater than general fine spining machine, can select to arrange several suction channels, both can the inside of machine, above, also can be below machine, the underground air that carries out that therefore is not precluded within cotton mill transmits.It is influence below and the preferred relevant key factor of suction system.
The total throughput of volume of air is particularly determined by the cross section of passage and the throttle point of all pipes and passage.
At the transition point place of pipe 402 or 408, air enters into passage 406, and/or at transition piece 416 " in air enter into passage 406, therefore this transition piece is designed to described oblique diffuser pipe.
If obtain having the words of fine spining machine of the twisting unit of the different degrees of compression, just obtained having suppressing and contracted or the material 71 of afterturn in spinning district, the spinning district will be arranged near the auxiliary pressure source shown in Figure 6, vertically more close auxiliary pressure source than fine spining machine, fine spining machine vertically will be away from auxiliary pressure source because said factor, the aux. pressure in suction channel fall must by the hole and/or similarly device carry out a spot of compensation.
The embodiment of suction system
As shown in Figure 8, the pressure problem of falling in suction channel 406 can run in the several blower fans that provided or a central blower fan, has shown several blower fans among the figure.In the general design of suction system, have only single blower fan 434 to link to each other with passage 406, opposite with Fig. 8, passage 406 extends on the whole length of fine spining machine 412.In Fig. 8, a passage 406 has only drawn between the right-hand member of outline line S2 and machine and/or framework 412.In this case, as shown in Figure 8, can design another passage 406, it extends to the left end of machine from the left end of outline line S2.Only also can be regarded as at the figure of the aspirator of outline line S2 left end and to substitute, also can substitute by two passage 406a and 406b by a passage 406.In this case, provide two auxiliary pressure source and/or two blower fan 434a and 434b.Every one thread passes through spinning district 5 and twisting unit 3, and many spinning district 5 and twisting unit 3 are arranged on machine one by one, and in lower left and the upper right side of Fig. 8, represent along the thick milgraining of framework 412 usefulness.The base that Fig. 8 has drawn spinning district and/or twisting unit or drafting unit 1, stay pipe 402 and/or suction tube 408 are installed with Fig. 5 and the described mode of Fig. 4, their direct admission passages 406 or enter chamber 416 ' this chamber and link to each other with passage 406 at outline line S2 left end.As can be seen from Figure 8, several pipe 402,408 each all lead in the chamber 416 '.
If in spinning machine, the demand of air is not equal to and greater than the air requirements amount in all spinning districts, just is suitable for making the passage 406 on the outline line S2 left side, 406a, the air-flow among the 406b and in the passage 406 on outline line S2 the right air-flow have different flow.For example, a central blower fan 434c is arranged, arrival end at blower fan 434c has a baffle plate 434e who is attached thereto, if baffle plate is tilted to the right as shown in Figure 8, so, width at the right passage 406 that enters the fans entrance place is narrower than left width of channel, and therefore more air-flow enters blower fan 34c from the left side.
On the other hand, also may arrange like this, on the right of machine and/or the right of outline line S2, a blower fan 434 specializing in right passage 406 is housed, in addition, on the left side of machine and/or the left side of outline line S2, a blower fan 434a is housed at least.As mentioned, also can provide several blower fan 434a, 434b is respectively applied for the air of passage 406a and 406b and carries.If several passages are arranged one by one along a side of machine, and passage 406a and 406b are all in the left side of outline line S2, preferably air communication is crossed stay pipe 402 and imported to first passage 406a, the suction air of suction tube 408 ' is imported another passage 406b.In order to influence the pressure of pipeline 406, baffle plate 434f also is equipped with in the porch of passage 406 that is preferably in the right of outline line S2.Described baffle plate has been arranged, and the pressure of pipeline 406 will be affected, if for example baffle plate 434f opens, aux. pressure may descend.In other words, if in the zone on outline line S2 the right, the effect of afterturn will be lower than the afterturn effect in the zone on the outline line S2 left side.Details will be described further following.
Lower left and top-right dotted line at Fig. 8 have been represented spinning apparatus 5 and twisting unit 3, and every one thread is through spinning apparatus 5 and twisting unit 3, and many spinning device 5 and twisting unit 3 are arranged along spinning machine.Spinning apparatus 5 links to each other with passage 406 and/or 406a by stay pipe 402 and/or suction tube 408 with twisting unit 3.
Put it briefly, give below in different suction systems, several possibilities of blower fan layout.
-as shown in Figure 8, provide single blower fan 434 at the right-hand member of machine, so passage 406 must extend on the whole length of machine.Yet, also can use two the passage 06a and the 406b that extend to entire machine length and import blower fan 434.
-two the blower fan 434a that are arranged in parallel, 434b makes air-flow from parallel passage 406a, and 406b flows into.
-outline line S2 place between the machine two ends arranges a blower fan 434c or two such blower fans, and an end is used for the passage 406 on the outline line S2 left side and/or the inspiration air-flow of 406a and 406b, and the other end is used for the inspiration suction air of outline line S2 right-side channels 406.
Various afterturns zone
If will produce several different yarns on a fine spining machine, using as shown in Figure 8 so, the layout of suction system has special advantage.Therefore in fact machine shown in Figure 8 has been divided into four parts by outline line S2 and S1, in spinning district 5, in machine both sides longitudinally, is arranging and is processing the many different materials or the commaterial of different condition.For example can provide these different conditions, because not every twisting unit 3 is all operating with a kind of mode, therefore for example a part afterturn and/or the part that is compressed in machine are carried out or are carried out in the several sections of the machine relevant with finishing afterturn.Because the afterturn effect depends on the suction operation of twisting unit, blower fan 434a, 434b, 434c and 434 different operating performance can access the degree of different compressions.On the other hand, have design of the same race or single blower fan 434c is only arranged, also can be by operation baffle plate 434e, 434f influences in each spinning district 5 and/or the suction operation of twisting unit 3.Obviously, the suction operation of each twisting unit 3 of every one thread stroke 73 only is subjected to the influence of the part and/or the section of single passage, for example only is subjected to the influence of passage 406a, and this passage extends in the zone below the outline line S2 left side and outline line S1.For the same yarn of producing different yarns or having different characteristic, also can be aptly, drive/start drafting unit by different way.The right at the outline line S2 on Fig. 8 top has only shown a drafting unit, and has shown two drafting units in the left area of outline line S2, and two respectively in the above and below of outline line S1.Every row of each drafting unit and/or drafting unit are by several conveying roller 11a, 11b, and 11c drives, and therefore, preferably stipulates each roller 11b, and 11c is motorized motions 11e.Label is that the motorized motions of 11e is meant and is comprising a frequency converter, and therefore, one or several this drive unit can be changed the degree of draft of drafting unit by this way by 435 controls of a control module.If a frequency converter is housed on drive motors, same blower fan driver element 434d can controlled device 435 influence, by this way, suction operation on entire machine or a part of machine all can adapt to spinning conditions, for example: below outline line S1 and this section on the outline line S2 left side.If have only a passage, suction rated performance on each twisting unit 3 can be by using the hole 430 of different size so, 431,432 change, in each section of machine, in the right of outline line S2 and the both sides up and down of outline line S1, in order to produce different yarns, on twisting unit 3 and spinning apparatus 5, arranged different spinning conditions accordingly.Therefore adjustment below and/or technical characterictic applicable to and/or can act on corresponding place.
-drawing-off amount on drafting unit is subjected to the influence of drive unit 11e;
-drawing-off distance is subjected to conveying roller 11a towards each other, the influence that b, c move;
-spinning apparatus, as roller cover, ring and the dividing plate in the drafting unit, also have ring, steel traveler 53, guard shield shape guide plate 39 and suction plug-in unit 37 in the spinning apparatus 5, therefore on suction plug-in unit 37.2, inhale the length of seam 40 and width according to the corresponding section of pass through and different, also can change the distance of celebrating a festival between device roller and/or the nip rolls 35 further according to the major length that will produce material 71.
The transport 71 of-various materials and/or be directed to the rove of drafting unit 1 and spinning district and;
-afterturn element 31, the quantity in the area of afterturn element 31 and hole are according to the respective section of needs in material conveying device 71 processes and fixed.
Certainly, the control device 435 of this fine spining machine designs by this way, if fine spining machine is relevant with electronics or electric equipment, the spinning program according to being input to control device can change different set.
According to the line of Fig. 8, control device 435 is can the control position as follows:
-be used for the drive unit 11e of drafting unit 1;
-be used for the drive unit 434d of blower fan 434a;
The drive unit 59 of-district's 5 spindles that are used to spin;
-be used for baffle plate 434e, the drive unit of 434f.
The needs of the different degrees of compression of yarn can be handled by down-stream, and as in textile mills, because according to the material that is used for warp or parallel, the demand of yarn may be different.For the practical application of difference compression and/or afterturn effect, as on all twisting units 3 above the outline line S1, its aux. pressure is greater than the aux. pressure of other twisting units of outline line S1 below.As a result, produced the yarn of different filoplumes in the both sides of outline line S1, yarn remaining technical parameter except that filoplume is identical.
