Background technique

Fly frame with corresponding air spinning jet nozzle is well known in the art, and for fine by elongated threadiness It ties up material and produces rove.In general, and preferably equally in fly frame according to the present invention, air spinning jet nozzle includes inside Minor air cell and the air nozzle for leading to minor air cell, are produced in minor air cell during the operation of fly frame by means of the air nozzle Raw vortical flow.Near the entrance opening that the yarn extended in minor air cell forms element, undulation degree is made by vortical flow The outer fiber of material is wound around interior core fibre, and is consequently formed for it is expected the vital package fiber of rove intensity.In this way Produce with the rove really twisted, the rove finally via take out channel is taken out from minor air cell and finally via export from Open air spinning jet nozzle.

In general, term " rove " (also referred to as " slubbing ") should be understood as meaning wherein extremely in the context of the present invention Few a part of fiber surrounds the fiber module of inner core winding.The yarn of the type is characterized in that, is enough although it has by yarn The certain strength that line transports subsequent weaving loom is horizontal, but it is still that can pull.Therefore, finally be spun into conventional yarns or It is processed into before knitted fabric, rove can be by means of drawing machine (for example, drawing machine, such as ring spinner or air are sprayed The weaving loom of spinning machine, or spinning braider) it pulls.Preferably, the fineness of rove is for 3.0ktex or thinner.

For example, describing this fly frame in 2511403 A1 of EP.

Summary of the invention

The purpose of the present invention is further develop correspondence fly frame and side for producing rove well known in the prior art Method.

The purpose is realized by the method and fly frame of the feature with independent claims.

The feature of method according to the first aspect of the invention in particular, in that, guided by means of feed arrangement with two individually The fibrous material of carding machine sliver form.Compared with prior art, therefore fly frame is not that single carding machine sliver is only supplied (for example, it can derive from upstream portion).But it is preferably derived from two two independent carding machine yarns for being supplied separately to device Item is fed into fly frame.Incidentally, feedway usually can be container well known in the prior art (so-called " spinning Bar cylinder ") or be also possible to carding machine sliver and have been deposited on to supply (specifically with limited way) and now thereon To the pallet of fly frame.

Feed arrangement can have more Element Designs and preferably include multiple part or parts, and some of them are divided each other Installation is opened, this will be explained in greater detail below.

Under any circumstance, it is specified that one in two carding machine slivers is filled during the normal operating of fly frame by feeding It sets and is supplied to drawing machine, and the beginning of another carding machine sliver is maintained at ready position by feed arrangement.In other words It says, the first carding machine sliver is mobile towards drawing machine in the normal operation period and is pulled by drawing machine into and the second carding machine yarn Item is remain stationary or is secured in place by feed arrangement and do not transported towards drawing machine.

Incidentally, carding machine sliver can be supplied to feed arrangement either manually or by processing unit appropriate.

Once the supply that above-mentioned first carding machine sliver derives from just starts carding machine sliver replacement process close to end, This has interrupted normal operating.During this carding machine sliver replacement process, makes previously to be fed into drawing machine and (but be still located at and lead Outside machine drawing) the initial part of end section and the carding machine sliver for being previously held in ready position of carding machine sliver connect Touching, and then by drawing machine by the end section and the carding machine sliver for being previously held in ready position it is described just Initial portion pulls (i.e. improved) together.The drawing of initial part enter can by once it be guided device release once by another The end section of a carding machine sliver is realized by being frictionally engaged pulling.In addition, before entering drawing machine or in one When between the further part (such as subsequent a pair of rolls) of feed rolls and drawing machine, it was previously supplied to the carding machine yarn of drawing machine The initial part of the end section of item and the carding machine sliver for being previously held in ready position may make contact or be overlapped.

Alternatively, feed arrangement also can have the element being described more fully below, and the element makes initial part court It moves until being pulled machine examination and measuring and is pulled in together with the end section of another carding machine sliver to drawing machine and lead In machine drawing.

After carding machine sliver replacement process, fly frame is operated again with normal operating, and in carding machine sliver New carding machine sliver is inserted at position at the first carding machine sliver and holds it in standard before replacement process Standby position, until starting new carding machine sliver replacement process.Carding machine yarn may be continuously supplied in fly frame in this way Item is enable to continuous production rove.

Advantageously, by the way that the carding machine sliver is secured in position in a clamped manner by means of clamping element, described The cotton carding that the drawing machine is supplied to before the carding machine sliver replacement process is generated in region before drawing machine The end section of machine sliver.Therefore, the part of the corresponding carding machine sliver having been positioned in the drawing machine be located at institute Being partially separated for clamping part upstream is stated, this is because the carding machine sliver is pulled by drawing machine and keeps solid in upstream It is fixed.Finally, the part separated with the carding machine sliver being drawn into is dropped or produces back to carding machine sliver.

The clamping of carding machine sliver is carried out preferably by means of feed arrangement, and the feed arrangement includes for this purpose can hand Dynamic actuating or the one or more clamping elements or clamping part activated automatically by means of actuation means.

Particularly advantageously, the initial of the carding machine sliver of ready position is maintained at before carding machine sliver replacement process It is mobile enough to remote to be partially toward a pair of of feed rolls or further part (such as at this to a pair of rolls after feed rolls), so that its quilt This captures feed rolls or above-mentioned further part and is supplied in drawing machine.

Incidentally, as described below, the carding machine sliver of ready position is maintained at before carding machine sliver replacement process The fact that must not necessarily be pulled in by a pair of of feed rolls of drawing machine, is also applied for being described below.Therefore, which enters It should be understood as only as example.

In the normal operation period, initial part be sufficiently apart from drawing machine so that it cannot by a pair of of feed rolls (or drawing The other parts of machine) it detects.Finally, the folder for example by displaceable support has occurred during carding machine sliver replacement process The movement for the initial part that tight element is initiated, the clamping element as feed arrangement a part and its position be fixed Or it is advantageously adjustable, so that clamping distance is adapted to fibre length, sliver fineness and/or other conditions.In order to more The purpose for being inserted into new initial part well can provide another position.It is advantageously possible to manually or automatically adjusting, being pre- It first calculates or position and movement is adjusted according to predetermined value (for example, fibre length or carding machine sliver fineness).

Advantageously, air spinning jet nozzle, drawing machine and retrieval unit stop before the overlapping of two carding machine slivers, And restarting is so that described two carding machine slivers are static during the overlapping after the overlapping.Cause This, can make carding machine sliver be in contact with each other in the case where no time pressure.Once carding machine sliver is overlapped, drawing Machine, air spinning jet nozzle and retrieval unit just restart, and by overlapping point and then by the cotton carding with initial part Machine sliver is pulled in drawing machine.

The rove initially generated can be supplied directly to rove retainer, such as be supplied to by the pipe or appearance of up- coiler driving Device (for example, yarning can).It is also contemplated that make rove initial part (its specifically further include by two be overlapped cotton carding The rove part that machine sliver is partially fabricated) it is taken out and is dropped by means of suction unit first after leaving retrieval unit.Finally The rove part is separated with the rove then produced.In this case, the rove only without the rove part is finally supplied It is given to rove retainer.

It is also advantageous that air spinning jet nozzle, drawing machine and pump unit are during the overlapping of two carding machine slivers Continue to operate.In this case, air injection spinning machine is continuously applied at least one carding machine yarn that rove is produced by it Item.Replacement from a carding machine sliver to another carding machine sliver is eventually as the one of above-mentioned carding machine sliver replacement process Part carries out, so that passing through interval interrupt normal operation of the carding machine sliver replacement process to recur.

During carding machine sliver replacement process, compared with normal operating, it can reduce speed of production and thereby reduce and lead Machine drawing is drawn out speed, if interrupting rove production and then as described above during carding machine sliver replacement process A part of the rove then produced is handled like that, then this is particularly advantageous.Therefore the rove amount to be abandoned is minimized.

Particularly advantageously, the thick point generated by the overlapping of described two carding machine slivers is pulled by the drawing machine, The drawing machine pulls thick point drawing-off used and is at least temporarily more than what drawing was pulled before the drawing of the thick point Drawing-off used in the carding machine sliver.Therefore, thick point is more strongly pulled, and it is longitudinal perpendicular to carding machine sliver that this reduce it The thickness of extension.After leaving drawing machine, the thickness of carding machine sliver is preferably continuous, so that after leaving drawing machine initially Existing thick point no longer exists, and the carding machine sliver with constant fineness is fed into air spinning jet nozzle.

This drawing-off change may be executed in a manner of time-based, so that increasing drawing-off when thickness point enters drawing machine. Equally, drawing machine may include one or more sensings of the thickness based on length for the carding machine sliver that monitoring enters drawing machine Device (for example, microwave resonator) and drawing-off is adjusted according to measured thickness.

In principle, the change of drawing-off can be suddenly or gradually and based in the control unit for being stored in fly frame Gradient and occur.Drawing-off and drawing-off gradient can be described from excellent by self-optimizing system with continuously or disposably method optimizing Change system learns and can also be called by automatic or manual to be learnt from past replacement process.

Due to change of the drawing-off during carding machine sliver replacement process, both do not need to abandon a part produced Rove does not need to interrupt spinning process yet.

Furthermore it is advantageous that being monitored by means of one or more sensors or according to by one or more of sensings The signal that device provides therefrom pulls the supply dress of the fibrous material to calculate the feed arrangement during rove production The fill level set.This allows to identify whether the carding machine sliver being currently pulled in drawing machine has lower than restriction threshold The residual length of value.If reaching the threshold value, can star carding machine sliver replacement process, thus prevent from being currently pulled into Carding machine sliver end its in the initial part of carding machine sliver of ready position it is Chong Die advance into drawing machine. About possible sensor and its arrangement, with reference to being described below.

Especially for the purpose for executing the method described so far, a kind of fly frame, the fly frame packet are proposed Include for fibrous material (it is preferably formed by above-mentioned two carding machine sliver) at least one feed arrangement, for pull Lai List is drawn out derived from a drawing machine of the fibrous material of feedway, an air spinning jet nozzle and one for rove Member.Air spinning jet nozzle is designed in air spinning jet nozzle by means of the whirlpool of the air nozzle generation by air spinning jet nozzle Vortex air flow is to (one i.e. in carding machine slivers multiple present on fly frame) application rotation of fibrous material, so that by described Fibrous material forms rove.Finally, the air spinning jet nozzle includes outlet, the rove can leave institute by the outlet State air spinning jet nozzle.

Feed arrangement, which is preferably included, can be taken out from feedway carding machine sliver by means of it and by carding machine Sliver transports at least one component or a group parts of drawing machine.Preferably, the component that independently works there are two or Component, so that (one of them is fed into drawing machine to two carding machine slivers in the normal operation period, and another is maintained at Ready position) it can move and be transported towards drawing machine independently of one another.Term " transport " it should be understood that exist and borrow Help its device that can transfer force to corresponding carding machine sliver (such as pairs of roller, the transmission with or without upper roller Band or even places cotton carding at the conveyer belt with or without sliding panel or cover board for carrying secretly and protecting on it Machine sliver and the single roller for continuing to promote carding machine sliver by rotation described below), the corresponding carding machine sliver passes through The power is come mobile towards drawing machine.Corresponding carding machine sliver need not be on its entire path between feedway and drawing machine It is actively mobile.

Usually, it is specified that feed arrangement includes two independent feeding parts, wherein each feeding part is designed to guide It fibrous material in the form of carding machine sliver and/or is transported to the drawing machine.Each feeding part preferably includes cotton carding Machine sliver can slide on the rail portion of drawing machine.Two rail portions can be a part of common guide rail, In this case, rail portion should be divided each other by declutcher control lever or other resolution elements (for example, one or more demarcation plates) From.It is therefore advantageous that being located in independent rail portion or two carding machine slivers thereon do not contact or only before drawing machine Nearby (in course of normal operation, a carding machine sliver moves in relative rail sections, and another for contact for side A carding machine sliver does not move in relative rail sections, until it during carding machine sliver replacement process quilt It is supplied in drawing machine).

It is also advantageous that each feeding part includes a pair of rolls, corresponding carding machine sliver can be by the pair of Roller guides clampedly and takes out from the feedway and led described in by the rotation of the roller in the pair of roller Machine drawing is mobile.Mutually reply roller is preferably placed at the upstream end of above-mentioned rail portion so that corresponding carding machine sliver by a pair of rolls from Feedway takes out and is placed in corresponding rail portion, it slides into drawing machine in the rail portion.Preferably, it borrows Help drawing machine to pull in carding machine sliver and therefore realize in rail portion the fact applying pulling force on carding machine sliver Movement.

As general remark, it is pointed out here that instead of a pair of rolls mentioned at each in the description, certainly It can be used and be preferably operably connected to single driver and be placed on carding machine sliver and moved in roller rotation Single roller.In addition, carding machine sliver can also be mobile by conveyer belt or be moved on it.Under any circumstance, sliver can To be carried secretly by its own weight, one or more rollers or sliding panel or cover board.

Preferably, rail portion is angled slightly downward will pass through gravity and support carding machine sliver on the direction of drawing machine Movement.

Under any circumstance, each pair of roller should also be as being driven by individual driver, and the driver is preferably located in accordingly A pair of rolls near.In addition, driver can should be activated for independently of one another leading independently of one another from its feedway Draw carding machine sliver.Specifically, in the course of normal operation of rove, a carding machine sliver should only be moved, however two Sliver takes out from its feedway sometimes and is fed into drawing machine (to allow during carding machine sliver replacement process The overlapping of described two carding machine slivers).

Furthermore it is advantageous that each feeding part includes compacting machine part, carding machine sliver is by means of the compacting machine portion Dividing can boot up and can compress in the side longitudinally extended perpendicular to carding machine sliver.Compacting machine part preferably includes Funnel shaped inner profile, so that passing through the carding machine sliver of the compacting machine part quilt in the direction perpendicular to its longitudinal extension traveling Compression.

It is also advantageous that compacting machine part is arranged side by side or preferably one is arranged on the other side, i.e., big It causes in the plane perpendicular to feeding clamp.If carding machine sliver is located in another plane, they should by one or The funnels or one or more individual component of multiple carrying carding machine slivers with or without coil at its position again Orientation, mode is so that their at least partly overlapped and earlier than drawing machine dominant drafts.

In addition, clamping element should compacting machine part associated or each with each compacting machine part should include clamp member Part.Clamping element is designed to clampingly fix the carding machine sliver guided by compacting machine part.For example, clamping element can It can be implemented in a manner of clamp and/or there is removable clamping surface (to be preferably by electrical, electromagnetism or pneumatic actuator To move), the removable clamping surface can be pressed between clamping surface and matching surface against matching surface movement Press carding machine sliver.If carding machine sliver is fixed in a clamped manner, carding machine sliver clamping element and drawing machine it Between the part that extends and the part for being located at guide rail upstream separate so that producing can weigh during carding machine sliver replacement process The end section being stacked on the initial part of another carding machine sliver.

Above-mentioned compacting machine part can be a part of common compacting machine or can be formed by individual compacting machine.

Particularly advantageously, the compacting machine part can be moved forward and backward independently of one another between at least two positions. In this case, compacting machine part may be mounted so that they can be rotated with linear movement and/or around pivot axis. It is also possible to realize the movement by electrical, electromagnetism or pneumatically actuated element.Under any circumstance, movement should make phase The compacting machine part answered is at first position than a pair of of feed rolls in the second place closer to drawing machine.This allow to by The carding machine sliver that ready position is maintained at during carding machine sliver replacement process is remote enough towards drawing machine movement, to make It is obtained to be caught and be drawn into drawing machine by a pair of of feed rolls.During movement, have occurred and the carding machine sliver that previously pulls End section overlapping so that two carding machine slivers advance in drawing machine together.

The detachability of the third place or element can be provided to facilitate automatic or manual and to load new carding machine yarn Item.

Specifically, it is advantageous to not entire compacting machine or compacting machine part, only the clamping part of clamping element or Clamping element may move back and forth between the two positions in this way as a whole, in this case, corresponding to clamp Part is at first position than a pair of of feed rolls in the second place closer to drawing machine.This is but also if initial part exists The mobile period of corresponding clamping part or clamping element is clamped, then the above-mentioned initial part of carding machine sliver can be towards drawing Machine and/or its a pair of of feed rolls are mobile, and are released again after by the capture of a pair of of feed rolls.

It is also advantageous that each of described compacting machine part has the exit opening for carding machine sliver, In this case, the minimum range between corresponding exit opening and a pair of of feed rolls of drawing machine is not more than 70mm. It, can also be by clamping section since the average fiber length of most of fibers that can be used for rove production is lower than above-mentioned maximum Divide the exit opening limited that can move enough to remote, in this case, the clamp and exit opening or folder of a pair of of feed rolls The distance between tight part is less than the average fiber length for being fed into the carding machine sliver of drawing machine.Thus be excluded that fiber It pulls out without the corresponding movement of carding machine sliver, allows to reliably pull carding machine sliver from drawing machine.

The invention further relates to a kind of methods for producing rove by fly frame, and the fly frame is in addition to drawing machine, sky Further include up- coiler except gas spinning jet nozzle and feed arrangement, the rove of air spinning jet nozzle will be left by means of the up- coiler It is wound into the Rove Package that the rove with limited amount is consequently formed on pipe.Incidentally, feed arrangement need not have elder generation All features of preceding combination feed arrangement description.For example, it is envisioned that it only includes a pair of rolls, with and without load member The conveyer belt of part or the single roller with single driver and the carding machine sliver guidance for will be taken out from feedway To the guiding piece of drawing machine.

Under any circumstance, when rove has the rove amount or storage thickness stored in the control unit of fly frame, The rove for reaching limited amount (can monitor corresponding data, or according to the winding process phase in initial blank pipe by sensor Between elapsed time calculate corresponding data).

According to the present invention, exist in the feedway after the production of the Rove Package if defined now Carding machine sliver amount be less than predetermined minimum amount, then interrupt the production of the rove.Feedway has preferably mentioned above The container or carding machine sliver arrived correspondence pallet disposed thereon.In the context of the present invention, " feedway " should be managed Solution is the rove for referring to thereon or in which being located fly frame to be delivered to, and from rove is wherein drawn out simultaneously then by rove It is supplied to the element of fly frame.

After the interruption of rove production, the carding machine sliver from new feedway is supplied to drawing machine, and will be by The rove of this production is wound on new blank pipe.During the production of above-mentioned Rove Package, expired with what blank pipe exchange had previously been wound Rove Package or blank pipe in up- coiler, the up- coiler has corresponding crosspoint, singly by means of the exchange Member replaces full Rove Package with new blank pipe.

Under any circumstance, ensuring that fly frame always only generates by the method includes the thick of predetermined minimum amount rove Yarn reel dress.Finally, the minimum can be influenced by the minimum of storage in a control unit, led when reaching the minimum Cause the interruption of rove production.

Particularly advantageously, the minimum corresponds to the carding machine sliver that must be supplied to the air spinning jet nozzle Amount, so that production has the Rove Package of the rove of limited amount with the help of the rove produced by it.Which ensure that fly frame Only produce the Rove Package being completely wound around.If fly frame recognize (such as by monitor feedway fill level biography Sensor) when Rove Package is completed, the amount for the carding machine sliver being still in feedway is no longer enough another by its production Described rove production disruption then occurs for a Rove Package being completely wound around.It then, will be from new full feedway Carding machine sliver is supplied to fly frame, and will be wound on new blank pipe by the rove of its production, to have limit by its production The Rove Package of quantitative rove.

In addition, fly frame can also include above-mentioned feed arrangement, two cotton cardings can be guided by means of the feed arrangement Machine sliver, so that above-mentioned carding machine sliver replacement process can also be carried out here.

In addition, the control unit of fly frame can be self study.For example, if it is recognized, it is contrary to expectations, it is supplying Being not enough to production to the carding machine sliver in device there are predefined minimum, (it is previously defined and deposits with limited amount Storage in a control unit) rove Rove Package, then it can adjust upward the level of the minimum automatically.

Particularly advantageously, the feed arrangement therefrom pulls the carding machine yarn during the production of the Rove Package The fill level of the feedway of item is monitored by means of one or more sensors or according to by one or more of sensing The signal that device provides calculates.About possible sensor, the rest part of reference book.

Likewise it can be beneficial to which the carding machine sliver passes through feed arrangement therefrom before the interruption that the rove produces It takes out and is fed into remaining carding machine sliver amount in the feedway of the drawing machine and is passed to and filled out with carding machine sliver Fill the weaving loom of feedway.For example, this weaving loom can be carding machine or drawing machine.Corresponding weaving loom usually will be with its phase The empty feedway of pass is filled into specified degree so that carding machine sliver amount and/or carding machine sliver length be corresponding generally to it is pre- Determine and be stored in the amount in the control unit of weaving loom.Advantageously, filling the degree of the feedway by the weaving loom It is adapted such that after the interruption of rove production, remaining carding machine sliver amount is minimum in the feedway.For example, If recognizing that the surplus of carding machine sliver is lower than the level for being enough to be formed another package on the winder plus expected Storage level, and equal to or less than leading machine set or be manually entered or with other simultaneously if the bar cylinder that newly calculates is horizontal The specified maximum value of mode (such as by calculating or based on table), then should correct the journey of weaving loom filling feedway upwards Degree.For example, the value of the surplus of carding machine sliver is higher than desired value if in addition recognized after rove production disruption, then answer When downwards, correction weaving loom fills the degree of feedway.The reason is that in feedway remaining carding machine sliver it is residual Allowance generally has to processed or is recycled to the production of carding machine sliver.Therefore, it is desirable to by the residual cotton carding in feedway Machine sliver amount is maintained at alap.

In this case, the connection between fly frame and weaving loom can be directly, or can also be via center Control system is sent by wired or wireless way by route.It is also contemplated that making fly frame delivering about carding machine yarn Described value, is then manually entered into the control unit of weaving loom by the value of the corresponding surplus of item.

Incidentally, if after rove production disruption, the carding machine sliver amount remained in feedway is more than 100 meters Length, preferably 50 meters of length, more preferable 10 meters of length, then should correct filling extent on the textile machine.Particularly, school It just should be so that the surplus of carding machine sliver mode as small as possible executes.

Further it is proposed that a kind of fly frame for by carding machine sliver production rove, the fly frame include being used for institute State carding machine sliver at least one feed arrangement, one for pulling the carding machine sliver supplied by the feed arrangement A drawing machine, an air spinning jet nozzle and a up- coiler, wherein the carding machine sliver can be filled by means of the feeding It sets and the drawing machine is taken out and be fed into from feedway, wherein the air spinning jet nozzle is designed to by means of by described The vortical flow that the air nozzle of air spinning jet nozzle generates applies the carding machine sliver in the air spinning jet nozzle It twists, so that forming rove by the carding machine sliver, wherein the air spinning jet nozzle has outlet, the rove can pass through The air spinning jet nozzle is left in the outlet, and wherein the up- coiler be designed to will from it is described outlet come out described in Rove is wound on pipe, thus generates the Rove Package with the rove of limited amount.

About above-mentioned term, with reference to previous description, wherein above-mentioned optional feature can also be individually or with not (being described in more detail below) is realized in fly frame with combination, and condition is not generate contradiction.

Under any circumstance, the fly frame being subsequently noted is characterized in that it includes control unit or is operably connected to Control unit, if wherein described control unit is designed to remaining in the feedway after the production of the package The amount of carding machine sliver is less than predetermined minimum amount, then interrupts the rove production.Specifically, fly frame is designed to carry out above-mentioned Method.Therefore, fly frame only generates the Rove Package with the rove for previously limiting minimum.Preferably, it is produced by fly frame All Rove Packages there is essentially identical rove amount, such as allow for less than 10 meters of rove and nominal value deviation.Tool Body, deviation should be as small as possible.It is further envisioned that still admissible minimum or deviation can be by operator's tune It is whole.

It is also advantageous that the fly frame includes one or more sensors, can be monitored by means of the sensor And/or it calculates therefrom to the filling position of the feedway of air injection spinning machine supply carding machine sliver.

One or more sensors can detecte the carding machine sliver amount being present in feedway in particular point in time Or the carding machine sliver amount taken out from current feedway, such as by ultrasonic method or also optically. Specifically, respective sensor may be implemented as infrared sensor or be detected the sensing of carding machine sliver based on visible light Device.It is also contemplated that the weight measurement of feedway.

It is particularly preferred that at least one sensor is implemented as camera (such as so-called IP Camera).By means of phase Machine can detecte carding machine sliver present in feedway.Equally, camera can be designed to identify the bottom of feedway Portion, such as the bottom of yarning can.It had previously been covered by carding machine sliver if detected by means of camera or other sensors Bottom, then this shows in foreseeable future, and all carding machine slivers will all be removed from the feedway.Particularly advantageous It is that the fly frame has control unit, it can be by the figure that is stored in described control unit by means of described control unit The signal of the camera is assessed as analysis software.By assessing the image shot by camera, therefore it can identify feedway Plumpness or at least close to emptying feedway.

One or more sensors may be mounted above one or more feedways, and preferably be directed toward from top Carding machine sliver and/or the bottom for becoming exposed feedway.Sensor vertically from above or can be obliquely directed towards supply On device or bottom.
