EP2106379B1 - Winding carrier and use of a winding carrier - Google Patents

Abstract

The invention provides various aspects of an improvement of winding carriers. The proposed winding carrier (1) enables for the first time to arrange both the thread reserve and the thread end reserve on a winding carrier such that they are protected when putting the bobbins together, yet easily accessible after the bobbins have been taken apart. Simultaneously the thread windings of two wound winding carriers come to rest at each other in a practically direct manner.

Description

The invention relates to a winding carrier and the use of a winding carrier.

Wrap carriers are used to be spooled with yarns. The yarns can then be dyed or otherwise processed. In particular, the wound reel carriers can be used in yarn-processing machines. For processing, the machine unwinds the yarn or, more generally, any desired thread from the winding carrier.

The winding carriers, which are often also called "sleeves", may be rigid or axially and / or radially deformable. However, they are usually shaped so that they are axially plugged together. They are at least substantially rotationally symmetrical and usually in one piece, sometimes executed in several pieces.

For storage, transport and dyeing, the winding carriers are stacked axially after being wound over one another. When the yarn is to be dyed, the winding carriers with the yarn wound thereon are nested on dyeing tubes to form yarn winding columns. These are then usually pressed together to form a homogeneous yarn winding column, in order to facilitate a uniform coloration.

In the case of reel carriers, the existing overall length, due to the winding width predetermined by the winding machine, is only partially wound, so that with correct positioning of the reeling frame at each end, part of the reel carrier remains unwound.

For example, plug-in roll carriers with a total length of 170 mm are very common. For example, an original wrap carrier has a first concave, solid plastic ring with a relatively large inside diameter at a first end, the receiving end. This is about 8 mm long. With unchanged outer diameter extends from there the winding surface, to about 8 mm in front of the opposite end, namely the mating side. There is a small annular groove at the end of the winding surface, which marks the winding limit. The sleeve jumps there in diameter radially inwards, towards a smaller inner diameter. There follows a cylinder jacket-shaped collar with a length of about 8 mm. At the first end, the receiving side, the inner diameter is 59 mm. At the end of the mating side, with the radially inwardly offset collar, the inner diameter is only 54 mm. The winding machine is set up to begin at one end of the winding carrier with the spooling. Since the winding carriers are not mirror-symmetrical, the winding machines have a larger receiving plate (for the larger inner diameter of the winding carrier, ie at the receiving end) and a smaller receiving plate (for the smaller inner diameter of the winding carrier, ie at the mating side, more precisely on the above collar). Conventionally, the machines are typically configured to begin spooling on the right side of the reel base. There, the so-called "thread reserve" is first wound on the edge. These are just a few turns of the yarn. Then the machine goes over to the actual winding area and rewinds the thread spool. At the end of Bespulvorgangs some turns can be wound as a so-called "final yarn reserve" also separate from the actual yarn package on the left side of the winding carrier.

Both a separately accessible thread reserve and a separately accessible final thread reserve facilitate unwinding, so the processing of the thread in the textile machine. When unwinding the thread reserve of the respective current coil is manually seized and connected to the final thread reserve of the next coil, usually knotted in practice.

This traditional Bespulung of wickelträger has in practice but with Färbehülsen, which are pressed, led to problems: When juxtaposing several bespulter winding carrier the edge with the large diameter, about 8 mm wide, on which the thread reserve was wound, remained as a gap between the Bobbins open. However, in order to achieve a uniform coloring, the yarn packages are compressed axially. in this connection The wound yarn slides over the thread reserve lying in the space between two bobbins and can then often no longer be found.

A remedy has the EP 0 201 826 B2 brought in practice as "AC sleeve" has become known. The AC sleeve is a rigid or compressible winding carrier, which has a winding surface with a cylindrical contour and at the mating end a radially smaller, closed collar in a known manner. On the radially smaller collar a groove is formed, which extends over almost the entire width of the collar. At the end of the closed plastic ring, however, is slightly widened. In the AC sleeve, the winding is usually such that first on the radially smaller, but axially projecting collar the thread reserve is wound and only then the winding of the remaining winding surface, wherein the closed, radially slightly expanded plastic ring at the receiving end of the AC Sleeve remains unwound. If two such bespulter winding carrier are inserted axially against each other, pushes the projecting collar at the plug end in a known manner in the receiving end of the adjacent sleeve. The thread at the end of the thread in the thread reserve groove (the thread reserve) thus immersed in the receiving end of the adjacent bobbin and is protected there: While compressing the bobbins for dyeing, the yarn bobbins move together. After pulling apart the sleeves, however, the thread reserve is still on the above collar.

These reel carriers or similar reel carrier have prevailed in spite of a costly plate change on the spulms of the winding machines as Färbehülsen in the market. The plate change was necessary because these winding carrier, contrary to the usual way, with the smaller inner diameter on the right side must be inserted into the bobbin frame and therefore the larger inner diameter is located on the left side.

A problem of the AC sleeve is that when pushed together - caused by the free, unwound ends - the front sides of the yarn package do not come to rest directly to each other. If such Garnwickelsäule pressed, so must first The outstanding unwound ends are pressed into the associated Garnwickel. Only then do the faces of the adjacent yarn packages come to rest, and only then does the compression of the entire yarn winding column begin. When pressing the unwound ends into the associated yarn package, the yarn layers lying directly on the package carriers, due to the perforation of the package carriers, are taken to the center, while the rest of the package remains unpressed in the original wound form, ie without any displacement of the yarn layers to each other. In this case, considerable relative displacements can occur between the moving yarn layers on the surface of the winding carrier and the non-moving yarn layers. The inner yarn layers are crucial for the proper operation of the yarn package and for the transition of the thread reserve to the next coil after dyeing in further processing. The "warped" inner yarn layers are in practice blamed for poor drainage or overflow of dyed yarn packages.

For those companies, which have carried out the conversion of the machines, which installed so the smaller receiving plate to the right, where the thread reserve is bespult, has the DE 39 09979 A1 a plug-in winding carrier described. This solves the disadvantage described above in that the end faces of adjacent yarn packages come to rest immediately on axially stacked coil carriers. The winding support proposed therein consists of a support surface with a radially inwardly offset collar, which serves to receive the thread reserve, and a continuously adjoining the support surface on the other side toothing. The winding begins even with this winding support first on the radially lower lying waistband with the winding of the thread reserve and then the thread runs on the wing over. The winding extends to the adjoining the support surface continuously toothing. If so wound winding carrier are plugged onto the dyeing tubes, the radially lower collar pushes with the thread reserve under the yarn-carrying sawtooth winding surface of the adjacent winding carrier. In addition, the two adjacent sawtooth areas should slide side by side under the end faces of the wound on adjacent reel carriers yarn. At the Pressing yarn packages on such winding carriers, the winding carrier are pressed from the beginning together with the yarn packages, whereby a relative displacement of the roll carrier and yarn package is avoided and the inner yarn layers remain in the original winding position on the winding surface

For this winding carrier stop shoulders are described, which limit an axial insertion of the winding carrier into each other. This means that the side surfaces of the nested teeth can come to rest. However, after the thread runs from the thread reserve through the toothing to the winding surface, the thread between the teeth can be easily clamped to the adjacent winding carrier side, which can lead to damage and localized non-staining of the yarn.

In addition, the inner diameter of the winding carrier with the outer diameter of the usual dyeing tubes is usually not identical, so that the winding carrier sit with a certain play on the dyeing tube, and when juxtaposing the wound carrier on the dyeing tubes, the freestanding teeth under unfavorable conditions on the covenant of bouncing adjacent wickelträgers, or the federal government may even intervene in the tooth spaces of the adjacent coil carrier, which can lead to damage of the affected teeth and the federal government and whereby the front sides of the adjacent coils can not come to rest. If such intermeshed winding carrier are subsequently pressed, destruction of the winding carrier is preprogrammed, with the yarn winding thereon also deform and usually unevenly colored.

In order to be able to wrap these winding carriers into the area of the toothing opposite the collar, which adjoins the supporting surface continuously, the winding frames of the winding machines must be displaced very much to the side with the toothing also to be tumbled and readjusted. Only in this way is a winding to the middle of the gearing, as proposed, only possible. On such set Spulrahmen no otherwise customary plug-in winding support can be wound more. Bobbin carriers of this type are therefore not known in the market in practice.

An excellent alternative for those manufacturers who had not converted their machines, which still had on the side of the beginning of winding, so with the thread reserve, the larger receiving plate on the right side, has the DE 42 02 029 A1 offered. This sleeve has become known in the market under the frame "eco-top". The eco-top sleeve is a plug-in coil carrier, in which the end faces of yarn packages come to rest axially on one another attached to the coil carriers. On this reel carrier, the thread reserve is first laid on a relative to the winding surface radially smaller federal government before the thread overflows onto the winding surface. When such wound roll carrier are plugged onto dyeing tubes, the federal government pushes with the thread reserve at the mating end under the winding area of the adjacent reel carrier at the receiving end. At the receiving end is located radially inside the winding surface first an annular slot-shaped receptacle for the collar of the adjacent coil. Radially further inside there is an axially extending from the sleeve additional collar, which has a smaller inner diameter than the collar at the mating end. The eco-top sleeve could therefore be used immediately in the original, unconverted machine and spooled there.

While the eco-top sleeve could be used immediately on the original machines, those manufacturers who had converted their plates for the AC sleeve, only very reticent have re-equipped the plates, although the eco-top sleeve has clearly better Abspuleigenschaften as the AC sleeve.

Other winding carriers are for example from the EP 1 375 406 A2 , of the DE 100 85 430 T1 , of the DE 199 17 767 C1 or the DE 696 06 907 T2 known. In addition, more winding carriers are known from the EP 1473400 A1 or the EP 0 472 507 A1 the latter discloses a sleeve with a color through lass for the thread reserve and the final thread reserve in gesppultem state.

In practice, a 290 mm sleeve is also known, which is constructed in the manner of the eco-top sleeve. At the mating end there is a collar with an inner diameter of 69 mm and an outer diameter of 73 mm. This collar is followed by a winding surface with an outer diameter of 78 mm. This extends up to an area of the final thread reserve with unchanged outer diameter. Radial within this Edge region is located at the local receiving end an annular slot for the protruding collar of an adjacent roll carrier. The slot is bounded radially inwardly by an axially projecting auxiliary collar having an inner diameter of 58 mm and an outer collar of 62 mm. On the outer surface of the additional Federal are integrally molded wedges, which increase the outer diameter by about 2 mm in the course of the additional Federal Republic to take up. These wedges run obliquely to just before the point where the additional collar dips into the edge area for the final thread reserve. There, the scope of the additional federation does not change any further. The reason for this widening of the diameter is to be seen in the fact that 290 mm sleeves in gesppultem state should often roll on discharge strips from the machine. In order for the sleeves to roll straight, it is necessary that the same diameter of the sleeve be found on the left and right on the drain strips. On the axially projecting additional collar with the smaller diameter therefore a Abrollring is attached, which corresponds in its outer diameter to the outer diameter of the collar at the mating end. Thus, the Abrollring securely clamps on the additional collar, the diameter of the additional collar is widened towards the sleeve body.

The invention has for its object to provide improved winding carrier available.

This object is achieved by a winding carrier with a winding surface for receiving a yarn package, and with a mating side and a receiving side for axial juxtaposition two identical winding carrier, wherein the mating side has a collar and wherein the receiving side a receptacle and radially within a collar axially out of the collar protruding additional collar, wherein the additional collar has a sliding brake, which counteracts the displacement of two bespulter winding carrier a displacement of a wound on the additional bundle reserve or Fadenendreserve under the collar.

It should be explained conceptually that the "sliding brake" acts in such a way that a thread start wound up on the additional bundle or a thread end wound there, that is to say the thread breaker Thread reserve or the final thread reserve, when nesting two roll carrier, so if the federal government on the side with the larger inner diameter on the additional collar with the side with the smaller inner diameter strikes, is not or not completely moved into the receptacle into it.

For example, it is envisaged that the sliding brake is arranged right there on the additional collar, where the additional collar dips axially into the receptacle radially within the end of the winding surface at the receiving end. In this case, the thread reserve or the final thread reserve as much space as possible.

A sleeve of the type proposed may be readily inserted into a machine which has rebuilt the plates to process AC sleeves, such that the smaller receiving plate has been moved to the right side to the position of the thread reserve feeder. In a sense, the sleeve proposed here can use an inverted eco-top sleeve as a foundation. The thread reserve is then spooled by the machine on the axially below the winding surface at the receiving end protruding additional collar, only then spins the machine on the actual winding surface. In this case, the final thread reserve can be wound on the waistband at the end of the line. In this way, both reserves, so the thread reserve and the final thread reserve, each on a separate from the actual winding surface and radially smaller configured collar, and when juxtaposing several bespulter winding support both reserves are protected, while the yarn are practically directly adjacent to each other. The proposed sleeve thus makes it possible for the first time that both reserves are protected in the stack of coiled winding carriers and remain easily accessible.

Theoretically, it would also be possible to simply put an eco-top sleeve "upside down" in a machine set up for AC sleeves. Even then a Bespulung the thread reserve on the additional collar would be noted. In attempts by the inventor, however, this - already innovative - approach has shown that the thread reserve is pushed by the federal government when inserting the additional covenant around in the recording, so that the thread reserve then can not be easily grasped to connect the unwinding of the coil, the thread with the thread of the next coil. Due to the sliding brake on the additional collar, the reserve shift can be counteracted. This has been successfully confirmed in numerous attempts by the inventor to prototype winding carriers.

It should be noted that a sleeve of the proposed type can also be used in machines set up for eco-top sleeves, in which the thread reserve is wound onto the bundle. In this case, the thread reserve is still wound on the collar at the mating end, then the main winding on the winding surface, and then the final yarn reserve is wound onto the axially projecting at the receiving end additional collar. Also in this Bespulung the above-described advantage that both the thread reserve and the final thread reserve are both protected and when pulling the juxtaposed bespulten wrap carrier both remain easily accessible on the collar or on the additional collar remain tangible.

The proposed winding carrier thus allows for the first time the simultaneous protection of yarn reserve and final yarn reserve with perfect handling, both on originally equipped machines as well as on converted machines for AC sleeves.

The sliding brake preferably has a step on an outer surface of the additional collar. As a step is understood an edge in the cross section of the additional federal. In extreme cases, the edge in the cross-sectional profile of the additional collar at an angle of 90 ° can be greater, which thus has an unsteady jump in diameter result. However, widenings with a smaller angle, ie ramp-shaped widening or frustoconical widening may also be present in stepped form. In both cases, there are axially extending sections with different, respectively constant diameters over the section or with constant diameter change gradients over the section.

In a step, which causes an expansion of the diameter in the axial direction, starting from the receiving end of the entire winding carrier to the winding surface, it is difficult for the thread to be pushed through the federal government into the receptacle. In contrast, when widening the other way around, it becomes particularly difficult for another sleeve, when pulled off, to completely pull down the thread from the additional waistband with its waistband. At the same time, such a geometry also acts to the effect that when mating the covenant of the other sleeve does not pull the thread into the receptacle, because the thread over the approaching covenant behind the radially larger step part can "hide".

A particularly preferred embodiment provides for a plurality of stages, wherein they can either exclusively increase or reduce the diameter in one direction or assume a maximum value or minimum value.

The sliding brake can be performed continuously or interrupted over a circumference of the additional collar. A continuous design is to be realized for example in a circumferential ring in the form of an edge. An interrupted, ie resolved, sliding brake can be seen, for example, in the arrangement of a plurality of individual radial projections on the additional collar, in particular under the edge of the winding surface.

It is conceivable that the winding carrier has a length of less than or more than 290 mm and that the additional collar has a conical circumferential enlargement axially towards the collar, which, however, passes into a uniform diameter before reaching the collar.

It has been described that there are 290 mm coil carriers, which have conical ramps in the outer area of the additional collar for clamping a rolling ring. However, the ramps end before reaching the collar and then run as axial webs with radially constant diameter under the collar into the receptacle. Such Geometry is known only from 290 mm sleeves and was not intended in any way for a thread reserve or used.

In the case of reel carriers having a length of 290 mm or having a greater or lesser length, it is proposed that the additional bundle has a conical circumferential enlargement axially towards the collar or another sliding brake which extends under the collar or is arranged there among other things.

The additional collar can have an attached and detachable or, for example, molded-on and detachable Abrollring, which leaves next to the collar an area on the additional covenant for a thread reserve or a final thread reserve available. With such a configuration, the spooled reel carrier can roll on unwind rails in a straight direction when the unwinding ring has the same outside diameter as the collar at the opposite end, namely the mating end of the reel base. Nevertheless, it is possible to rewind the thread reserve or the final thread reserve on the additional collar provided with the unrolling ring.

With a suitable design of the Abrollring can be used as a step on the outer surface of the additional Federal.

A simple design provides that the Abrollring is designed to be slidable so that it can be pushed under the collar when two identical center girders are put together. In this case, the Abrollring should be axially shorter than the recording radially outside of the additional collar and radially within the collar.

According to a second aspect of the invention, the stated object solves a winding carrier, in particular of the type described above, with a winding surface with a wound up yarn package, wherein a reserve of thread and a final yarn reel are wound on the federal government and on the additional covenant, in any arrangement, so the thread reserve and the final thread reserve when axially juxtaposing two bespulter winding support are both protected.

This advantage has already been explained above. However, it should be emphasized that for this purpose a sliding brake does not necessarily have to be present. Rather, either a state can already be tolerated, in which the thread reserve and the final thread reserve are indeed protected, but the reserve that is on the additional collar is pushed into the receptacle when the sleeves are pushed one against the other. With a small hook can be, for example, by once driving around the circumference of the inner sides of the collar, the overflowing thread point still grab, even if this has an increased effort compared to the variant described above with sliding brake result.

Alternatively, the federal government at the plug side of the winding support ensure that the thread is not detected as possible at its overflowing point by the federal government and pushed into the receptacle on the additional collar. For example, the waistband may be jagged or serrated there.

An embodiment of the federal government, which causes a reduction in the insertion of the thread into the receptacle on the additional collar, is an alternative and cumulative to the additional covenant with and without a sliding brake advantageous and inventive.

The spooled winding carrier is preferably designed so that when juxtaposing two such winding carrier the yarn package with a distance of a maximum of about 1 mm to about 3 mm together. The yarn packages are then almost immediately adjacent to each other, limited only by the narrow edge adjacent to the grooves on the winding surface, which mark the Beszustungsgrenze to prevent slippage of the roll from the winding surface. When pressing for dyeing, this results in almost no shifts within the yarn package.

According to a third aspect of the invention, the stated object solves the use of a winding support, in particular of the type described above, with a winding surface and a mating side and a receiving side for axial juxtaposition of two identical winding carrier, wherein the mating side has a collar and wherein the receiving side a Recording and radially within a collar having an axially protruding from the collar collar, for spooling on a machine which winds a thread reserve on the side with the smaller plate, so that the thread reserve is wound on the winding support on the additional covenant.

This essentially covers those machines that have been converted to use AC sleeves, and to which coil carriers with the eco-top geometry could not previously be used.

It is understood that the use of such a coil carrier on a machine set up the other hand is automatically advantageous, so on a machine which has arranged on the right side, where the thread reserve is wound, the larger plate. This applies in particular to machines that have spooled eco-top sleeves so far.

It should be expressly emphasized that the invention extends on the one hand to the geometry of the winding carrier, but on the other hand, for use on an arbitrarily designed winding machine or spinning machine.

schematically a detail of a winding carrier with a thread reserve groove on an additional collar and a detail of a tool.

The FIG. 1a shows a longitudinal section through a cylindrical winding carrier in a schematic representation, with a rotationally symmetrical body 1. The body 1 forms a winding surface 2, which is adapted to the intended use and by z. B. spaced apart, connected by axial webs rings is perforated or may be unperforated. On the winding surface 2 is followed on one side by an axially projecting, radially inwardly offset teeth 16, the teeth are preferably evenly distributed annular. The outer diameter of the toothing are evenly distributed in a ring. The outer diameter of the toothing 16 is adapted to the inner diameter of the under the other end of the winding surface 2 lying, radially inwardly offset receptacle 7 for the toothing 16. The receptacle 7 is formed by a boundary 8 and completed. The boundary 8 is followed by a radially inwardly offset, axially projecting additional collar 6, whose outer diameter is adapted to the inner diameter of the toothing 16, wherein the outer diameter of the additional collar 6 is dimensioned so that the winding surface of the thread reserve 14 bespult and on the additional collar 6 in the recording 7 a gain 9 (shift brake) can be inserted. In the FIG. 1 this reinforcement is 9 (sliding brake) in section in one piece with the additional collar 6, but drawn without conical lowering on the additional collar 6. The toothing 16 is formed by way of example conical, wherein the tooth heads 18 are made round and flattened.

The FIG. 1b shows a view of a winding carrier with a view towards the receptacle 7. The tangential course of the thread 29 is indicated by a dashed line. The overflow aid 28 is shown.

The FIG. 2a shows a section through two similar, rectified, nested winding support with a stop in the receptacle 7 at the boundary 8 and the end face of the Federal 10th

The FIG. 2b shows a section through two similar, rectified, nested winding carrier with a stop on the end faces 11 and 12. An overflow aid may be advantageous to prevent jamming of the thread.

The Figure 2c shows a section through two similar, rectified nested winding support with a stop between the front side of the additional collar 13 to one or more stops 25th

The Figure 2d shows a section through two similar, rectified, nested winding support with a stop between the end face 13 of the additional collar, and running as an inner stops spacers 27th

The FIG. 2e shows a section through two similar, rectified, nested winding support with a stop in the receptacle 7 at the boundary 8 by preferably uniformly distributed nubs 31 on the front side of the collar 10th

With such attacks, the overflowing thread can be better protected.

The FIG. 3 shows a view of another cylindrical coil carrier with a truncated wavy teeth 16 and with a lower end, in which the winding surface 2 is partially cut in the region of the boundary 5 and in which the lying under the winding surface 2 sliding brake 9 can be seen.

The FIG. 4 shows on the one hand a view of a winding carrier with an axial view of the side with the interrupted by the teeth 16 collar and on the other side to a continuous collar 10th

The FIG. 5 shows an enlarged section of the FIG. 3 and shows by way of example in particular details of an embodiment of the toothing, which is offset radially inwards. The tooth side surfaces 21 and the axially outer tooth surfaces 20 are conical and the tooth heads 18 show a round design with tilted sliding surfaces 22nd

The FIG. 6 shows a further view of a winding carrier with an axial view of the side with the toothing, wherein the teeth are arranged overlapping and the tooth gaps 23 are formed by relatively narrow recesses, which are preferably aligned tangentially to the surface of the additional collar 6. In comparison with the FIG. 4 one recognizes immediately that with the overlapped version there is the interesting possibility of making the individual teeth very wide without having to make the tooth gaps correspondingly wide. This particularly affects the nesting of neighboring, rectified Wickelträger particularly favorable. In widely spaced teeth of the additional collar 6 can penetrate in the worst case in one or more tooth gaps 17 and prevent the immediate contact of the end faces 11 to 12

The FIG. 7 shows a sectional view of the toothing 16 of a winding carrier according to FIG. 6 in which it is particularly evident that the toothing 16 presents as a closed ring, whereby the nesting of adjacent straightened coil carrier is facilitated.

The FIG. 8 shows a sectional view of the toothing 16 of a winding carrier according to FIG. 6 in which the slot depth is much lower.

The FIG. 9 shows a longitudinal section through an advantageous winding carrier, in which the spacer elements 26, 27 can be seen. A number of the spacer elements 27 is designed (as an example) as an inner stop for limiting the insertion depth.

A Abrollring according to the prior art has the disadvantage that it must be removed after the winding of the winding support and before further processing, since the winding support with drain ring are not plugged into each other.

The unrolling ring presented here, for example, can be pushed so far into the receptacle after being spooled that it does not obstruct the nesting of the winding supports. Preferably, it can be pushed completely into the receptacle for this purpose.

It can consist of a ring, which is attached to the additional collar and there z. B. is fixed by small increases. If you then attach a similar second winding support, the drain ring is moved by the collar 4 in the receptacle 7. The intake must be sufficiently deep to leave room for the drain ring and collar.

It can also consist of several rings that are connected by buckling elements. This gives him a wider area to unroll. When nesting, these buckling elements buckle, saving space in the receptacle.

The Abrollring may also have webs, on the one hand enlarge the rolling surface and on the other hand slide into each other when nesting in additional openings in the recording and so save space in the recording or create.

A roll-off ring for a coil carrier having a first region with a peripherally closed surface and with a second region having a perforated surface, in particular with a tangentially resolved surface in the form of protrusions protruding from the closed surface, wherein the perforated surface is adapted thereto, is advantageous to be inserted into a receptacle on the winding support and there selectively occupy a first and a second position, wherein the openwork surface in the first position from the receptacle of the winding support partially protruding, but can absorb a bending moment occurring during rolling, and wherein the Abrollring is completely inserted into the receptacle of the winding carrier in the second position.

In some types of winding machine the finished wound reel carrier is deposited by the machine on two Abrollschienen and rolls on this independently to a position from which it can be removed for further processing. The winding carrier rolls with its free ends on the Abrollschienen. In the case of reel carriers according to the eco-top patent, there is the problem that the outer diameter of the free ends is different, so that the finished wound reel carrier runs in a circle when rolling on the Abrollschienen, which can lead to disturbances in the operation. It has been solved this problem by a Abrollring, which is attached to the additional collar and clamped in the receptacle. As a result, the additional covenant is no longer suitable as a winding surface for a thread reserve or final thread reserve, since the Abrollring removed before further processing of the coils becomes. The outer diameter of the unwinding ring corresponds to the outer diameter of the collar and thus ensures a straight rolling of the coils.

In contrast, an advantageous Abrollring this does not extend into the receptacle 7 of the winding support, but is attached to the end of the additional collar, so that the winding surface remains free and thus usable.

The FIGS. 10 and 11 are cuts of FIG. 9 ,

The FIG. 12 shows a winding carrier with Abrollring 30. The Abrollring is clamped on the front side of the additional collar 6 and the winding surface for the thread reserve remains free and thus usable. The outer diameter corresponds to the outer diameter of the collar 4.

A Abrollring which is to be moved under the collar 5 and thus into the receptacle, is preferably arranged so that it leaves axially on the additional collar 6 to the front side of the sleeve out of place for the thread reserve or for the final yarn reserve. In comparison to FIG. 12 The Abrollring and the reserve are the other way around.

Particular aspects of the invention may serve to make the existing winder machines usable without re-adjustment or rebuilding of the bobbin frames,

that when nesting wound, unidirectional winding support the wound on the additional collar of a winding support thread reserve can not be moved from the collar of the adjacent winding support in the recording and thereby damaged and / or can not be recovered for further processing,

that, when nesting wound, unidirectional winding carriers, the end faces of the neighboring yarn packages located thereon are immediately approaching or completely in abutment,

that in nested wound, rectified winding carriers not only the thread reserve, but also the final thread reserve is protected and immediately accessible again after disassembly of the yarn columns,

that the guidance of the winding carrier on the dyeing tubes and the nesting of the coil carriers is improved with each other,

that the winding carrier on winding, twisting and OE machines, which are set up for either "AC" or for "eco-top" can be used without plate replacement or further retooling.

For example, an aspect is solved in that means on the collar 4 and / or on the receptacle 7 are present, which prevent a complete slipping of the thread reserve into the receptacle 7, or limit.

On the one hand, this can be achieved by the collar 4 receiving a toothing or slots into which the thread 29 overflowing from the thread reserve onto the collar 6 to the winding surface 2 can be inserted. The other means, alternatively or cumulatively, is a sliding brake on the additional collar 6, which prevents the yarn from being pushed too far into the receptacle 7. This brake can z. B. are formed by a circumferential ring 9.

The winding support consists of a body 1 with a winding surface 2 with an axially projecting at one end annular collar 4, the axially projecting teeth at its end or may be slotted, which is adapted in its outer diameter to the inner diameter of the other end of the winding surface 2 and under which, radially offset inwardly, a receptacle 7 for an annular collar 4 is located, which ends at a boundary 8 to which a radially inwardly offset, axially projecting additional collar 6 connects, partly as a winding surface for the thread reserve 14 at the foot can serve and whose outer diameter is adapted to the inner diameter of the collar 4 at the other end of the winding carrier.

The winding carrier may be formed so that the body 1 of the winding body is cylindrical, conical or at least partially cylindrical and that the arranged at one end of the winding surface 2 axially outwardly directed collar 4 and the toothing 16 is offset radially inwardly in that the outer diameter of the collar 4, or of the toothing 16, is adapted to the inner diameter of the other end of the winding surface 2, wherein the winding surface 2 can also be flush in the collar 4 or the toothing 16. In this case, with a corresponding depth of the receptacle 7 and a corresponding design of the tooth valleys 17, a very close contact of the end faces of the yarn package together with possibly even a slight pressure against each other can be achieved.

The winding of such winding carrier begins with the laying of the thread 29 on the winding surface for the thread reserve 14 on the additional collar 6. After laying the thread reserve of the thread 29 then runs from the additional collar 6 on the free space of the receptacle 7 and the end face of the collar 12 on the Wickelfläche 2 on and the actual winding is then carried out on the entire winding surface 2. At the end of the winding takes place, if desired, the laying of the final thread reserve on the collar. 4

Now, if the same shape, wound bobbin with the teeth 16 axially introduced in another such wound, rectified coil body slides the teeth 16 and the collar 4 on the additional collar 6 in the receptacle 7, wherein in the best case of the winding surface for the thread reserve 14 over the additional collar 6 and the free space of the receptacle 7 to the winding surface 2 overflowed thread 29 placed on the adjacent roll carrier in a tooth gap 17 of the inserted winding carrier and remains unhampered. In contrast, if a tooth head 18 strikes the thread 29, these tooth heads 18 must be designed so that the affected tooth 16, the thread 29 pushes aside and safely under-or over-runs. The end faces of the adjacent yarn packages come after nesting for immediate investment, without a mutual underneath of the yarn carrying toothed surfaces with the associated risks of damage and entrapment is possible.

The winding support can be designed so that the toothed gaps directed towards the winding surface 2 17 in the axially outwardly directed teeth 16 advantageously axially to about 7 below or next to the winding surface 2 of a rectified winding carrier, with which the former roll carrier is connected by insertion , or beyond.

The winding support may be formed so that at least the tooth heads 18 are narrower and thinner than the remaining areas and advantageously, to ensure easy nesting adjacent, unidirectional winding carrier and a trouble running underneath or over running the thread 29, all edges the winding carrier, if necessary, rounded and the tooth heads 18 round and / or rounded.

In the winding carrier, the toothing 16 may be symmetrical or asymmetrical. In an asymmetrical design of the teeth, the teeth 16 preferably follow the direction of the over-running thread. As a result, the course of the thread during further processing can be improved.

In the winding carrier, the teeth 16 of the toothing may be formed overlapping, wherein the tooth gaps 17 may reduce to narrow slots, which are preferably aligned tangentially to the winding surface of the thread reserve 14 on the additional collar 6. In the overlapped version, there is the interesting possibility of making the individual teeth very wide, without having to make the tooth gaps correspondingly wide. This has a particularly favorable effect on the nesting of adjacent, unidirectional winding supports. In widely spaced teeth of the inserted additional collar 6 can impinge on the teeth 16 or in the worst case penetrate into one or more tooth gaps 17. This can lead to damage to the winding carrier and prevent immediate contact of the end faces 11 and 12 of the winding surfaces 2 of the winding carrier. In the winding carrier, the overlapping teeth 16 form an almost closed ring, which presents itself as a one-piece collar upon contact with the additional collar 6 of the adjacent winding carrier and thus avoids the above-described problem. In addition, the widened, overlapping shape of the teeth 16 enhances the rigidity of the individual teeth 16. In addition, a reduction in the slot depth may cause further reinforcement of the teeth 16.

The winding carrier may be formed so that the length of the teeth 16 and / or the depth of the receptacle 7 is dimensioned so that they abut when nesting two rectified winding carriers at the end of the receptacle 7 to a boundary 8 and thereby, to avoid damage of the additional collar 6 to the winding surface 2 overflowed thread 29, the adjacent winding carrier with the end faces 11 and 12 of the winding surfaces 2 do not come to rest. The stop of two nested winding carriers can also be formed by a contact between the end face 13 of the additional collar 6 and the end face of a continuous to the other side of the entire surface or as a web extension of the boundary 25.

In conical or partially conical winding carriers, the length of the teeth 16 and / or the depth of the receptacle 7 may be such that when nesting of two similar winding carriers of the beginning of the teeth 16 can slip below the winding surface 2, whereby an immediate contact of the End faces of the yarn package together and possibly even a slight pressure of the yarn package against each other may arise.

The winding support may be formed so that the axially inner tooth surfaces 19 and the axially outer tooth surfaces 20 of the toothing 16 and the adjoining tooth heads 18 are flattened, so that the teeth 16 when nesting the winding carrier tangentially from the winding surface for the thread reserve 14 on the additional collar 6 to the winding surface 2 overflowed thread 29 on the adjacent roll carrier may indeed touch, but safely under or over.

In the winding support, at least the tooth surfaces 19 located radially in the region of the tooth heads 18 and / or the radially outer tooth surfaces 20 of the toothing 16 can be tilted and / or flattened to sliding surfaces 22 at the angle predetermined by the tangentially overflowing thread 29 , This results in the nesting of wound winding carriers improved under, or driving over the tangential of the winding surface for the thread reserve 14 on the additional collar 6 to the winding surface 2 overflowed thread 29 on the inserted winding carrier.

The winding carrier can be designed so that on the additional collar 6 is an at least partially annular reinforcement 9 as a stop shoulder (slip brake), which prevents nesting of adjacent winding carriers displacement of the wound yarn reserve in the region of the receptacle 7. The reinforcement 9 can preferably run out of the region of the receptacle 7 in a wedge shape on the additional collar 6 and can be provided with a slip-resistant surface. Due to the wedge shape, the toothing 16 of a winding carrier is guided and centered in the receptacle 7 of the adjacent inserted winding carrier.

In the winding support of the additional collar 6 serves partially as a support 14 for the winding of a thread reserve. In order to facilitate the winding of the thread reserve, the additional collar 6 can also be formed with a so-called. Fadenreservenut and / or with grooves and / or with the adhesion of the yarn surface improving, the possibilities described above at the same time replace the effect of the annular reinforcement 9 or can complement.

The winding of the winding carrier preferably begins on the winding surface for the thread reserve 14 on the additional collar 6 of the winding carrier. The actual winding of the body 1 takes place on the winding surface 2. For better limitation, at one or both ends of the winding surface 2 suitable winding boundaries 3, z. B. depressions and / or elevations and / or an anti-slip surface can be provided. The overflow of the thread 29 from the winding surface for the thread reserve 14 on the additional collar. 6 to the winding surface 2 via the sometimes smooth edge of the end face 12 of the collar to the winding surface 2, wherein the thread 29 runs tangentially from the additional collar 6 to the winding surface 2.

In general, there is a game between the winding carrier and the usual dyeing tube, which causes the teeth 16 or the tooth gaps 17 impact on the additional collar 6 when plugging the spooled winding carrier on the dyeing tubes under unfavorable conditions and the affected teeth 16 or Tooth gaps 17 and the additional collar 6 can be damaged. To reduce this possibility, on the radially inner surface 24 of the body 1, annular, distributed on the circumference, rigid and / or flexible spacer elements 26 are provided, which improve the leadership of the winding carrier on the dyeing tube. These spacers 26 may be formed by inwardly formed cams, ring segments or by a webbing. You can also serve as a stop 27 at the same time.

To avoid undercuts and associated problems in the production of the winding support described here, the core of the tool, in particular injection molding tool, have axially extending grooves, which then serve to form these spacers 26, 27 on the sleeve inside, the tool jaws reach into these grooves ,

The winding carrier may be one or more pieces, cylindrical, conical or otherwise formed. The material used may preferably be plastic, cardboard / paper, metal or a combination of these materials. It can be perforated or unperforated and rigid or radial and / or axially deformable. It can be used for any winding customary on the market. The features can be used for winding and transport wrapping and for Färbewickelträger.

In the execution of the winding carrier without or only with a low tooth depth is when nesting straightened winding carrier pressure on the of the federal government 6 to the winding surface 2 running yarn 29 exercised, which leads without suitable means to the fact that the thread reserve shifts into the receptacle 7. By acting as a sliding brake reinforcement 9 on the collar 6 but prevents the thread reserve completely shifts into the receptacle 7. It could only move a few turns of the thread reserve in the recording. The rest of the thread reserve remains accessible even after the disassembly of the nested wrap carrier and is thus usable.

Such winding carriers can be used without conversion both on winding machines, which are set up for AC sleeves, as well as on machines that are set up for eco-top sleeves.

In the case of a winder, which is set up for AC sleeves, the thread reserve, as described above, placed on the additional collar 6 and is protected there after nesting by the collar 4. The final yarn reserve is placed on the collar 4 and there is also protected after nesting under the collar 5.

In the case of a winding machine, which is set up for eco-top sleeves, the thread reserve is placed on the collar 4 and is there protected by the nesting under the collar 5. The final yarn reserve is placed on the additional collar 6 and is protected there after nesting in the same manner as the thread reserve on a winder that is set up for AC sleeves.

The thread reserve is a winding that is applied to one end of the winding carrier at the beginning of the winding process. It is intended to make it possible, at the end of the bobbin, for the thread to be knotted at the beginning of the next bobbin even before the unwinding process has finished, so that the unwinding process can continue without interruption.

At the final thread reserve is a winding at the end of the winding process on the already initially laid thread reserve opposite end of the Wickelträgers is applied. It serves to find the end of the thread easier so that it can be tied to the thread reserve of the next bobbin.

It should be noted that a winding support with annularly extending on the radially inner surface, circumferentially distributed, rigid and / or flexible spacer elements 26 which improve the leadership of the winding support on the dyeing tube, regardless of all other aspects, which above are described, advantageous and inventive.

Likewise independently advantageous and inventive is a tool core, in particular on an injection mold, with axially extending grooves, which serve to form the spacer elements 26, 27 on the sleeve inner side, wherein the tool jaws reach into these grooves.

With regard to a winding carrier, it is independently advantageous if, in addition to a tooth system (16, 17), a continuous collar is provided, so that the two identical winding carriers can only be inserted coaxially into one another.

It is also advantageous with regard to a winding carrier if the toothing (16, 17) has a circumferential jacket.
