Description
Technical field
The present invention relates to a kind of according to claim 1 as described in the preamble, for processing the drafter of at least one fibre combinations.
Background technology
Most of this kind of drafters have charging lower roll that powered and position is fixedly supported and the discharging lower roll that powered and position is fixedly supported. Moveable and load charging top roll is distributed, so that the fibre combinations entered is clamped between charging top roll and charging lower roll for charging lower roll. Fibre combinations is driven by charging lower roll also by frictional connection as feed side top roll. Equally also distribute moveable and load discharging top roll for exit side lower roll, so that the fibre combinations gone out also is clamped between discharging top roll and discharging lower roll. Driven by discharging lower roll also by frictional connection at this fibre combinations and discharging top roll. Realize the stretching of fibre combinations in the following manner, namely utilize the circumferential speed more significantly higher than charging lower roll to make discharging lower roll rotate, so that the fiber of fiber composition is essentially pulled apart from one another along conveying direction in drawing zone.
In order to realize the Uniform Tension of fibre combinations and avoid the mistake stretching of fibre combinations, (as such as in DE102005056534A1) arranges Conductivity of Fiber leading-in device in the drawing zone of drafter.Including band and lower band at the Conductivity of Fiber leading-in device shown by DE102005056534A1 at this, wherein fiber composition guides between upper band and lower band. Lower band surrounds around the bridge that charging lower roll and position are fixing at the bottom side place of drafter and runs, and is driven by charging lower roll via frictional connection. In the top sides of drafter, upper band surrounds around the deflecting element that charging lower roll and position are fixing and runs, and is connected with lower band by frictional connection. Deflecting element is configured to retainer form, and is arranged in rigidly in drawing zone.
In the top sides of drafter, deflecting element and on be provided with the pressure elements of rigid plate form between band. At this, pressure elements utilizes himself weight to be resisted against on the inner surface of band, and is pressed against around bridge on the lower band run by upper band by the regional area of Conductivity of Fiber leading-in device. The fibre combinations guided between the two strips is thus born by the regional area of Conductivity of Fiber leading-in device in the ideal case and is applied to the lower uniform thrust with place. In order to strengthen thrust, it is that pressure elements loads additional spring force by being fastened on the helical spring at deflecting element place.
In practice it has been shown that be resisted against the regional area of the Conductivity of Fiber leading-in device brought via pressure elements, fibre combinations to be tensioned does not bear and is applied to the lower uniform thrust with place. Instead, thrust then focuses on one or more compacted position or clip position, and described compacted position or clip position produce during stretching in this regional area of Conductivity of Fiber leading-in device. At described compacted position or clip position place, fibre combinations is clamped between upper band and lower band due to the thrust of pressure elements. In addition it has been shown that compacted position or clip position are subjected to displacement during stretching, so that the clip position of fixing restriction will not be produced in Conductivity of Fiber leading-in device.
Can it is therefore seen that one of uneven thrust main reason is that, fibre combinations diameter over its length changes, say, that have Hou Chu and Bao Chu alternately over its length. Type according to spring, fibre combinations thus be clamped in thick place or be clamped in thin place. When using the spring that the diameter reacting condition of fibre combinations is less intense, harder, fibre combinations bears the whole thrust at thickness place. As a result of which it is, the fibre combinations at thickness place clamps between the two strips, and the thinner part of fibre combinations does not clamp. If fibre combinations carries during thickness is in stretching and moves forward, then therefore clip position is subjected to displacement along Conductivity of Fiber leading-in device. On the contrary, when using the spring that the diameter reacting condition of fibre combinations is stronger, softer, pressure elements is lifted momently by the thick place in fibre combinations, and along the thinner part direction run-off the straight of fibre combinations. Therefore, clip position is along the direction displacement at the thin place of fibre combinations. Based on Hou Chu and the Bao Chu being alternately present in fibre combinations, thus pressure elements bears lasting banking motion during stretching. It means that even for softer spring, the clip position in Conductivity of Fiber leading-in device is not defined yet. Thus fibre combinations clamping in Conductivity of Fiber leading-in device can not be controlled fully by described Conductivity of Fiber leading-in device. The stretching quality of fibre combinations is had a negative impact by this.
Therefore, the task of the present invention is in that to improve Conductivity of Fiber leading-in device, make controllably to clamp fibre combinations to be tensioned in Conductivity of Fiber leading-in device, that is, described Conductivity of Fiber leading-in device should have a fixing clip position limited, at described clip position place, fibre combinations bears uniform thrust.
Summary of the invention
Within the scope of the present invention, fibre combinations can be regarded as that be made up of, elongated formation single fiber, and the length of described fiber is significantly smaller than the length of described formation. Fibre combinations especially can produce on carding machine, combing machine or drafting machine, the fibre combinations of the essentially no twist, and described fibre combinations is processed on the flyer spinning be assembled with drafter and is provided with the rove that protection is twisted with the fingers. Fibre combinations can also be provided with the rove that protection is twisted with the fingers, and described rove is being assembled with on the spinning machine of drafter, such as ring spinner and is being processed into complete twist yarn.
At this, drafter according to the present invention is applicable not only to spinning preparation machine, such as flyer spinning, drafting machine, it is also applied for spinning machine, such as ring spinner, especially when these equipment have many operating positions producing rove or yarn wherein respectively. At this it is also contemplated that the multiple fibre combinations being jointly stretched for drafter feeding at operating position place.
Additionally, drawing zone can be regarded as the region between the clamping line of two adjacent rollers pair, stretch fibre combinations wherein. At this, lower roll is the roller that is fixedly supported of position and top roll is roller that is that be movably supported and that press against on lower roll. Typically, top roll is arranged in and is associated with above its lower roll. But it is also contemplated that such drafter, wherein fibre combinations substantially perpendicularly extends, wherein the top roll of roller pair and lower roll can be arranged in juxtaposition in this case. Conductivity of Fiber leader tape is the structure of ring-type, around deflecting element around running so that it is along rotation direction, is at least resisted against fibre combinations place in the substantial portion scope of drawing zone and moves in the way of corresponding to fibre combinations.
Invention task is solved in the following manner according to the present invention, namely described pressure elements has the pressure arm (16) being under spring force, and described pressure arm utilizes first end be arranged on described deflecting element place and utilize the second free end to be resisted against on the described inner surface of described Conductivity of Fiber leader tape by the contact surface linear that carries out extending on the width of described Conductivity of Fiber leader tape under the effect of described spring force. So that (the clamping line) that be capable of approximately linear and the clip position therefore clearly limited, be ensure that stretching relation constant in stretching field and the thick-and-thin quality of yarn to be formed by described clip position.
Especially foregoing can be achieved in, namely when the conveying direction along described fibre combinations, when the described contact surface of described pressure arm has the length between 1 to 4mm. Preferably, this length can be between 1 to 3mm. Advantageously, pressure elements is configured to elastic spring element. At this, spring element has pressure arm, and the pressure of approximately linear is applied on the inner surface of Conductivity of Fiber leader tape by this spring element by described pressure arm.
In run location, the second free end of pressure arm is offset from its resting position by fiber guide element. Based on elastic spring element or the spring performance that is in pressure arm under spring force, bear the restoring force along its resting position direction at this its second free end. Thus, thrust is utilized to be pressed against on fiber guide element by Conductivity of Fiber leader tape.
Unlike the prior art, described fibre combinations to be tensioned is clamped between Conductivity of Fiber leader tape and fiber guide element by pressure elements or its position being in the accurately restriction in Conductivity of Fiber leading-in device of the pressure arm under spring force of such as elastic spring element form. Additionally, ensure that fibre combinations bears against the thick-and-thin thrust of fiber guide element at clip position place by described spring element (pressure elements) elastic, that be provided with pressure arm. At this unlike the prior art, it is that the elastomeric spring effect self of the pressure arm of spring element passing through to use produces transverse to the thrust that the conveying direction of fibre combinations is directed. As a result of which it is, can be precisely carried out the fibre combinations with diameter scrambling in Conductivity of Fiber leading-in device guiding, the Uniform Tension of fibre combinations is produced Beneficial Effect by this. Test is it has been shown that when deflecting element is tightly secured in drawing zone, the pressure arm of elastic spring element or the thrust of elastic spring element are maximum, and the Conductivity of Fiber leader tape in drawing zone is around described deflecting element tensioning and around running. The second free end thus achieving the pressure arm of spring element utilizes whole restoring force to be resisted against Conductivity of Fiber leader tape place.
By pressure elements is designed to the embodiment of elastic spring element, simplifying the structure of drafter, this is owing to being different from prior art when using proposed spring element, it is not necessary to use the additional spring for producing thrust.Elastic spring element preferably combination by metal and plastics or by metal and plastics forms. At this, pyrite proves to be advantageous for as metal, and Teflon proves particularly advantageous as plastics, and this is owing to the outstanding part of this kind of material is in that not only have good spring performance and have good sliding properties.
Prove that at this this is advantageous for, for simplicity, described spring element is configured to leaf spring.
It is also advantageous that, described spring element is configured to U-shaped. At this, it is bending that U-shaped can be understood as leaf spring, and is made up of two supporting legs (i.e. the first supporting leg and the second supporting leg). Two supporting legs are mutually arranged with a spacing and form opening in its end. Via the first supporting leg, leaf spring is fastened on deflecting element place, and wherein said leaf spring utilizes the free end of the second supporting leg to be resisted against on the inner surface of Conductivity of Fiber leader tape. In run location, the free end of the second supporting leg is offset along the first supporting leg direction from its resting position by fiber guide element, so that the spacing between two supporting legs reduces and makes opening reduce. Based on its spring performance, the second supporting leg is by offseting the restoring force born along its resting position direction. Thus, thrust is utilized to be pressed against on fiber guide element by Conductivity of Fiber leader tape.
In addition it is also proposed a kind of embodiment, the described free end of wherein said pressure arm is moveably mounted along the direction of described fiber guide element (12) and is resisted against described deflecting element place, and the spring element being fastened on described deflecting element place is connected with the operation of described free end. At this, although (as quoted in the prior art) also needs to the spring element added, but also realizes only pressure load linear, that include foregoing advantage at this by the favourable structure of pressure arm.
Can be understood as the pressure arm in the end being connected with deflecting element is pivotally supported at deflecting element place around rotation axis on the one hand in statement " movably ". On the other hand, it is also possible to consider a kind of embodiment, wherein the one end of pressure arm is fixedly secured in deflecting element place, and free end can flexibly move in specific region based on the elasticity of pressure arm.
Particularly advantageously, described fiber guide element is fixing and has the fiber guidance surface of spill, and described Conductivity of Fiber leader tape is resisted against on described fiber guidance surface. The fiber guidance surface of spill contributes to, the clip position of the fixing restriction in generation Conductivity of Fiber leading-in device in drawing process. In addition eliminate, by described fixing fiber guide element, the another one Conductivity of Fiber leader tape using drafter bottom side place unlike the prior art, thus greatly reduce the upkeep cost of spinning machine.
In addition this advantage that can bring, when the conveying direction along described fibre combinations, described Conductivity of Fiber leading-in device is made up of feed zone, clamp area and discharge zone. Feed zone so implements wedgewise at this, and namely the spacing between Conductivity of Fiber leader tape and fiber guidance surface reduces towards clamp area. Thus fibre combinations is directed in Conductivity of Fiber leading-in device without fiber with departing from. In described clamp area, described Conductivity of Fiber leader tape is parallel to described fiber guidance surface and extends, say, that the profile of fiber guidance surface followed by Conductivity of Fiber leader tape. In discharge zone subsequently, by the fiber guidance surface of fiber guide element by fibre combinations with thering is no clamping action bite direction along discharge roller pair guide unilaterally.At this, the end of fiber guidance surface is positioned on straight connecting line, and described connecting line extends through bite and the described spring element described contact point on described Conductivity of Fiber leader tape of described discharge roller pair. Thus, fibre combinations obtains in the end of Conductivity of Fiber leading-in device stretching the offset portion that quality produces actively to affect.
At this advantageously, not only feed zone but also clamp area have the length of 2 to 15mm. Make it possible to be directed to Conductivity of Fiber leading-in device fibre combinations with departing from without fiber from the bite of feed roller pair by the geometry designs of feed zone. On the contrary, then being ensure that by the geometry designs of clamp area, the fibre combinations in Conductivity of Fiber leading-in device obtains and guides fully, and this is especially advantageous for for the fibre combinations being stretched in its uniformity and tightness.
In addition this has the advantage that, namely elastic spring element utilizes its free end in region, clamp area to be resisted against on the inner surface of Conductivity of Fiber leader tape, so that form clip position in clamp area. Have turned out at this and be advantageous for, namely when clip position is arranged in the front area of clamp area. Thus, in the front area of clamp area, Conductivity of Fiber leader tape bears stronger thrust, and wherein the described Conductivity of Fiber leader tape in the Background Region of clamp area is mildly resisted against on fiber guidance surface.
In addition this has the advantage that, namely the described end of described clamp area and the described bite of described discharge roller pair are arranged with the spacing of 8 to 15mm. The end of clamp area refers to that at this clamp area is transitioned into the position of discharge zone, and Conductivity of Fiber leader tape is no longer abut against fiber guidance surface, and fibre combinations no longer guides between Conductivity of Fiber leader tape and fiber guidance surface. Ensure that based on the spacing between end and the bite of discharge roller pair of clamp area, fibre combinations obtains guiding fully in drawing zone.
Also demonstrate that and be advantageous for, namely when the conveying direction described pressure elements adjustable ground along described fibre combinations is fastened on described deflecting element place. So that the thrust of spring element can adapt to the fiber joint portion stretched in drafter, so that the fibre combinations of different characteristic can stretch in drafter with thick-and-thin quality. It is clamped in fully in Conductivity of Fiber leading-in device in order to ensure fiber jointer, it has therefore proved that this is advantageous for, is namely in the scope of 0.5-5N in the thrust at clip position place. Spring unit can be regulated stepless or discontinuously at this. When carrying out step-less adjustment, spring unit such as can be adjusted by adjustment screw, adjustment wheel or the guide part at deflecting element place. Such as realizing the discontinuous adjustment of spring element in the following manner, namely in order to hold spring unit, deflecting element has bolt, and spring element has the hole being arranged in juxtaposition, and wherein spring element is placed on the bolt of deflecting element by a hole. By inserting spring unit, the length of clamp area and discharge zone is thus enable accurately to adapt to the fibre combinations stretched in drafter.
It is also advantageous that when described discharge zone has the length of 1-4mm. Thus, fibre combinations guides fully until the bite of discharge roller pair, and the quality of this fibre combinations on being stretched produces actively impact.
It is also advantageous that, the combination by metal or plastics or by metal and plastics of the described fiber guidance surface forms. At this, pyrite proves particularly advantageous as metal, and Teflon proves particularly advantageous as plastics, this is because this kind of material is distinguished by good sliding properties. When fiber guidance surface has the coating reducing friction, it is also advantageous that. Reduced the friction produced between Conductivity of Fiber leader tape and fiber guidance surface by this type coating, it reduce the energy expenditure of spinning machine and the abrasion of especially Conductivity of Fiber leader tape. In order to realize anlistatig characteristic, coating that the fiber guidance surface of fiber guide element can also have conduction, that be especially made of metal.
In addition this is advantageous for, and namely described fiber guide element is fastened on the support place that position is fixedly placed in drafter, is enable to make fiber guide element carry out installing and removing at support place.It is possible to not bigger cost and change the fiber guide element damaged. This be such as bolted or shape connect fiber guide element is fastened on support place.
Finally this is also advantageous that, namely fiber guide element adjustable ground is fastened on support place. The length thus enabling clamp area and discharge zone accurately adapts to the fibre combinations stretched in drafter, so that the fiber composition of different characteristic can stretch in drafter with thick-and-thin quality.

Detailed description of the invention
Fig. 1 illustrates the schematic side elevation of the drafter 1 of spinning machine, and it is with Conductivity of Fiber leading-in device 10 traditional, as known from the prior art. Spinning machine can especially spinning preparation machine (such as flyer spinning, drafting machine), or spinning machine (such as ring spinner). The fibre combinations 2 of the entrance that drafter 1 is arranged to be stretching in drawing zone 3, such as fiber band or rove, so that form uniformly refining fibre combinations 25. Drawing zone 3 at this between the charging side roller bite 24 and the discharging side roller bite 21 to 5 to 4.
Such as exit side lower roll 9, feed side lower roll 7 position is fixedly supported and drives. At this, moveable and load feed side top roll 6 is distributed for feed side lower roll 7, so that the fibre combinations 2 entered is clamped between feed side top roll 6 and feed side lower roll 7, wherein fibre combinations 2 and feed side top roll 6 are driven by frictional connection. Equally also distribute moveable and load exit side top roll 8 for exit side lower roll 9, so that the fibre combinations 25 gone out is clamped between exit side top roll 8 and exit side lower roll 9, wherein also it is driven by frictional connection at this fibre combinations 25 and exit side top roll 8. Realize the stretching of fibre combinations 2 in the following manner, namely utilize the circumferential speed more considerably higher than feed side lower roll 7 to drive exit side lower roll 9, so that fiber moves relative to each other in drawing zone 3, say, that the conveying direction F along fibre combinations 2 is essentially pulled apart from one another.
In order to ensure fibre combinations 2 Uniform Tension and avoid fibre combinations 2 mistake stretching, in the drawing zone 3 of drafter 1 arrange Conductivity of Fiber leading-in device 10. Conductivity of Fiber leading-in device 10 includes the lower fiber guide element with 29 forms, lower is configured to ring-type with 29, and guides on feed side lower roll 7 and the bridge 27 fixing around position is around running. At this, lower band 29 is driven by charging lower roll 7 by frictional connection. At the upside place of drafter, Conductivity of Fiber leading-in device 10 has another one Conductivity of Fiber leader tape 11, and described Conductivity of Fiber leader tape is configured to ring-type equally, and is directed on feed side top roll 6 and around deflecting element 13 around running.Upper band 11 is connected with lower band 29 by frictional connection at this and is driven by lower band 29. Deflecting element 13 is configured to retainer form, and is fastened on the fixing axis place of charging top roll 6.
Deflecting element 13 and on 11 between be provided with the pressure elements 14a of rigid plate form. At this, pressure elements 14a utilizes himself weight to be resisted against with on the inner surface 11a of 11, and presses against upper on the regional area of Conductivity of Fiber leading-in device 10 around bridge 27 on the lower band 29 run with 11. Thus born by the regional area of Conductivity of Fiber leading-in device 10 in the ideal case at two fibre combinations 2 with guiding between 29,11 and be applied to the lower uniform thrust with 29 places. It is applied to the lower thrust AK with the fibre combinations 2 on 29 to strengthen, loads additional spring force by being fastened on the helical spring 26 at deflecting element 13 place for pressure elements 14a.
One of the drafter 1 with Conductivity of Fiber leading-in device 10 that figure 1 illustrates main disadvantage is that, fibre combinations 2 to be tensioned do not bear on the regional area of Conductivity of Fiber leading-in device 10 be applied to lower with 29 on uniform thrust, in described regional area the pressure elements of rigid plate 14a form be resisted against band 11 on. Instead, thrust then focuses on one or more compacted position or clip position, and described compacted position or clip position occur in this regional area of Conductivity of Fiber leading-in device 10 during stretching. At this, described compacted position or clip position refer on this place's fibre combinations 2 is clamped in based on the thrust of rigid plate 14a with 11 and lower with 29 between position. The another drawback of Conductivity of Fiber leading-in device 10 is in that, compacted position or clip position are subjected to displacement during stretching, so that will not produce the clip position of fixing restriction in Conductivity of Fiber leading-in device 10.
Can it is therefore seen that one of uneven thrust main reason is that, fibre combinations 2 diameter over its length changes, say, that have Hou Chu and Bao Chu alternately over its length. Type according to spring 26, fibre combinations 2 thus be clamped in thick place or be clamped in thin place. When using the spring 26 that the diameter reacting condition of fibre combinations 2 is less intense, harder, fibre combinations 2 bears the whole thrust at thickness place. As a result of which it is, the fibre combinations 2 at thickness place is clamped between two bands 11,29, and the thinner part of fibre combinations 2 does not clamp. If fibre combinations 2 moves forward together with thickness place during stretching, then clip position is subjected to displacement along Conductivity of Fiber leading-in device 10. On the contrary, when using the spring 26 that the diameter reacting condition of fibre combinations 2 is stronger, softer, rigid plate 14a is lifted momently by the thick place in fibre combinations 2, and along the thinner part direction run-off the straight of fibre combinations 2. So that clip position is subjected to displacement along the direction at the thin place of fibre combinations 2. Due to the scrambling of the diameter of fibre combinations 2, thus rigid plate 14a bears lasting banking motion during stretching. It means that even for softer spring 26, be not clearly limited to the clip position in Conductivity of Fiber leading-in device 10 yet. Thus the fibre combinations 2 clamping in Conductivity of Fiber leading-in device 10 can not be controlled fully by described Conductivity of Fiber leading-in device 10. The stretching quality of fibre combinations 2 is had a negative impact by this.
Fig. 2 illustrates the schematic side elevation of an exemplary embodiment of the drafter 1 according to the present invention of spinning machine, wherein Conductivity of Fiber leading-in device 10 includes Conductivity of Fiber leader tape 11, and described Conductivity of Fiber leader tape surrounds operation around feed side top roll 6 and around deflecting element 13. Conductivity of Fiber leader tape 11 is driven by feed side lower roll 7 by frictional connection. Deflecting element 13 is configured to retainer and is rigidly fastened in drawing zone 3. Additionally, Conductivity of Fiber leading-in device 10 includes fiber guide element 12, described fiber guide element has the fiber guidance surface 17 of spill to guide fibre combinations 2. Fiber guide element 12 is detachably fastened support 23 place by being clamped and connected, and is enable to make fiber guide element 12 simply and quickly carry out installing and removing at support 23 place. Change the fiber guide element 12 of damage with it is possible to not bigger cost. Arranging at this, support 23 extends on multiple operating positions of spinning machine, is wherein in each operating position on support 23 and fastens Conductivity of Fiber draws element 12.
The pressure elements 14 being configured to elastic spring element it is provided with between deflecting element 13 and Conductivity of Fiber leader tape 11. Elastic spring element 14(pressure elements) utilize first end 15 be fastened on deflecting element 13 place and utilize the second free end P to be resisted against linearly on the inner surface 11a of Conductivity of Fiber leader tape 11. Second free end P is positioned at pressure arm 16 place of spring element 14. In run location, the second free end P by fiber guide element 12 from its resting position RL(Fig. 3) offset. Based on the spring performance of elastic spring element 14, bear the restoring force RK(Fig. 3 along its resting position RL direction at this second free end P). Thus, thrust AK is utilized to be pressed against on fiber guidance surface 17 by Conductivity of Fiber leader tape 11.
Unlike the prior art, by elastic spring element 14, in Conductivity of Fiber leading-in device 10, fixing that limit, linear clip position 22 place waits that stretching the fibre combinations 2 drawn is clamped between Conductivity of Fiber leader tape 11 and fiber guidance surface 17. In addition ensure that, the fibre combinations 2 at clip position 22 place bears against the thick-and-thin thrust AK of fiber guidance surface 17. At this unlike the prior art, the thrust AK transverse to the conveying direction F orientation of fibre combinations 2 is produced by the elastomeric spring effect of spring element 14 self. As a result of which it is, be precisely carried out the fibre combinations 2 with diameter scrambling in Conductivity of Fiber leading-in device 10 guiding, the Uniform Tension of fibre combinations 2 is produced Beneficial Effect by this.
Along the conveying direction F of fibre combinations 2, Conductivity of Fiber leading-in device 10 is made up of feed zone 18, clamp area 19 and discharge zone 20. Feed zone 18 so implements wedgewise at this, and namely the spacing between Conductivity of Fiber leader tape 11 and fiber guidance surface 17 reduces towards clamp area 19. Thus fibre combinations 2 is directed in Conductivity of Fiber leading-in device 10 without fiber with departing from. The length of feed zone 18 is between 2-15mm. In clamp area 19, Conductivity of Fiber leader tape 11 is parallel to fiber guidance surface 17 and extends, say, that in clamp area 19, and the profile of fiber guidance surface 17 followed by Conductivity of Fiber leader tape 11. Test is it has been shown that the spacing having between the length of 2-15mm and the end of clamp area 19 and the discharge roller bite 21 to 5 when clamp area 19 is when 8-15mm, it is achieved yarn value (Garnwerte) preferably.The end of clamp area 19 refers to that at this clamp area 19 is transitioned into the position of discharge zone 20. In the end of clamp area 19, Conductivity of Fiber leader tape 11 is no longer abut against on the fiber guidance surface 17 of fiber guide element 12, or fibre combinations 2 no longer guides between Conductivity of Fiber leader tape 11 and fiber guidance surface 17. In discharge zone 20 subsequently, by fiber guidance surface 17, the direction of the bite 21 of 5 is guided along discharge roller by fibre combinations 2 with not having clamping action unilaterally. At this, the end of fiber guidance surface 17 is positioned at straight connecting line 28(or plane) on, described connecting line extend through discharge roller to 5 bite 21 and clip position 22. Thus, fibre combinations 2 obtains in the end of Conductivity of Fiber leading-in device 10 offset portion stretching quality generation positive role. It is to say, single fiber guides in region between the ensuing bite 21 to 5 in offset portion and discharge roller by being equal to the offset portion of depression bar. The length of discharge zone 15 is 1-4mm.
Fig. 3 illustrate be fastened on deflecting element 13 place, be in resting position RL and the schematic side elevation of spring element 14 in deviation post, wherein illustrate with dashed lines the spring element 14 in deviation post. Spring element 14 is configured to the leaf spring of U-shaped, and described leaf spring is made up of the first supporting leg 15 and the second supporting leg 16. Two supporting legs 15,16 are mutually arranged with a spacing and form opening 30 in its end. Via the first supporting leg 15, leaf spring 14 is bolted 31 adjustable grounds and is fastened on deflecting element 13 place, and wherein this leaf spring utilizes the second supporting leg 16(pressure arm) free end P be resisted against on the inner surface 11a of Conductivity of Fiber leader tape (at the not shown described Conductivity of Fiber leader tape of Fig. 3). In run location, second supporting leg 16(pressure arm) free end offset along the direction of the first supporting leg 15 from its resting position RL by fiber guide element (at the same not shown described fiber guide element of Fig. 3) so that spacing reduction between two supporting legs 15,16 and make opening 30 diminish. Based on the spring performance of leaf spring 14, the second supporting leg 16 bears the restoring force RK along its resting position RL direction due to skew. Thus, thrust is utilized to be pressed against on fiber guide element by Conductivity of Fiber leader tape. The fibre combinations guided between Conductivity of Fiber leader tape and fiber guide element is clamped in this position. By leaf spring 14(pressure elements) adjustable ground is fastened on the bottom side of deflecting element 13, additionally, there may be the probability that clip position and thrust accurately adapt to the fibre combinations stretched in drafter. In like fashion, the fiber composition of different characteristic can stretch in drafter with thick-and-thin quality.
With the exemplary embodiment of Fig. 3 the difference is that, figure 4 illustrates a device, wherein substitute the leaf spring 14(pressure elements of U-shaped), pressure arm 16 is fastened on deflecting element 13. At this, indicating such as double-head arrow, pressure arm 16 is installed around axis 33 pivotly at its first end 15 place. Pivot axis 33 is arranged on extension 34, and as schematically indicated again by double-head arrow, described extension is bolted 31 adjustable grounds and is fastened on deflecting element 13 place. In the groove 35 of deflecting element 13, fastening pressure spring Q, the other end of described compression spring is connected with the pressure arm 16 in the region of its second free end P.
The spring element that can also use other substitutes spring Q. In first end 15 region of pressure arm 16, pressure arm 16 can also be permanently connected with deflecting element 13. In this case, be constructed so as to pressure arm so that this pressure arm can implement elastic deflection, so that free end P can be flexibly not shown in the diagram along fiber guide element 12(in a specific region) direction motion.
In run location, the free end E of pressure arm 16 is offset to position shown in phantom from its resting position RL along deflecting element 13 direction by fiber guide element. Thus, Conductivity of Fiber leader tape utilizes thrust to press against on fiber guide element under the effect of spring Q. At this, as shown in the partial view amplified in Figure 5, the free end P of pressure arm 16 is resisted against on the inner surface 11a of Conductivity of Fiber leader tape 11 by contacting surface A F, and form a restriction and constant clip position 22. Along conveying direction F due to contact surface A F 1 to 4mm(or 1 to 3mm) narrow structure, there is the clip position of approximately linear, described clip position is insensitive for the quality fluctuation in fibrous material. As known from the profile A-A of Fig. 6, pressure arm 16 is almost extending with on the whole width b of 11, and by being with 11 to pressure is applied on fibrous material 2, described fibrous material guides on the fiber guidance surface 17 of fiber guide element 12.
Utilize proposed embodiment, it is ensured that constant and thick-and-thin sandwich relationship in main stretching field, described sandwich relationship does not rely on the quality fluctuation in fibrous material.
