Abstract

The invention relates to a bobbin (2) having a winding (10) of a tape winding (3). Two rings (13; 14) are wound with a winding (3) on the outer circumferential surface (11) of the winding (10). The rings (13; 14) have an axial spacing (15) which is smaller than the width B (18) of the winding (3). The end (17) of the winding (3) is thus fixed on the bobbin (2) in such a way that it is introduced into the gap (16) between the two rings (13; 14), where the end (17) is then fixed in a friction-locking and/or form-locking manner relative to the outlet. Additional fastening means, such as adhesive, welding or the like, for fastening the release end (17) of the wrap (3) are therefore not required.

The present invention relates to a bobbin with a winding of a tape winding. The invention further relates to a method for winding such a spool. Another aspect of the invention relates to a winding machine. Finally, the invention relates to a software product with suitable control logic for executing the method for winding a spool or the control unit for a winding machine.

In particular, said spool, said winding machine, said method and said software product are applied in connection with a spool in which,

the tape winding is configured as a monofilament or multifilament tape material, in particular a plastic tape (for example consisting of PP, PET and/or PE) and/or is configured with filaments or "threads" of less than or equal to 4;

the tape wrap has a length of at least 10000 meters, preferably at least 20000 meters, or 50000 meters;

the tape wrap has a thickness of 0.01 mm to 0.20 mm with a width in the range of 1 mm to 8 mm (preferably, 0.02 mm to 0 with a width in the range of 2 mm to 6 mmA thickness of 12 mm);

the maximum diameter of the winding is at least 200 mm, 250 mm, 280 mm or 320 mm;

and the above description should not be taken as limiting the invention.

The term "tape wrap" is to be understood here as: the windings do not have a circular cross section but have flat ratios (ablottung) at least on two opposite sides. Preferably, the tape winding has a (at least approximately) rectangular cross section.

Background

Document WO2003/099695a1 discloses a winding machine in which the stepwise winding of the spools on two winding spindles driven separately is effected. The winding spindles are held in this case on a turret (revolute) which is rotatable parallel to the axis of rotation of the winding spindle. Depending on the rotational position of the turret, these winding spindles can be in a winding position (Spulstellung) and a change position (Wechselstellung). In the winding position, the spool is wound on the winding spindle. In the replacement position, the completely wound spool is removed from the winding spindle. In the replacement position, the thread can also be disconnected after the spool has been completely wound on the winding spindle before being removed. The end of the previous thread formed by the severing should here still be wound onto the circumference of the complete bobbin. In contrast, the thread start thus formed is to be gripped and fixed there by the capture region of an empty winding sleeve which is located on a further winding spindle which is in the winding position. Subsequently, a new winding process on the new winding sleeve is then carried out. The severing of the thread can be achieved here by tearing due to increased stress of the thread and/or by means of a cutting device. The collection area can be arranged on the respective winding sleeve within the laying width or outside the laying width. The collection region can be configured here, for example, as one or more cut-outs arranged distributed over the circumference of the winding sleeve, or can also be formed by means of hook tape strips (hakenbandstriefen). It is also possible for the collection area to be formed by the winding spindle and thus independently of the winding sleeve. Document WO2003/099695a1 also describes that the thread is fixed on the winding sleeve by means of a fixed winding. The fixed winding (Fixierwick) is understood to be: a raised winding of the thread, in which the thread layers are wound tightly next to one another and/or overlapping one another in a narrowly delimited axial region of the winding sleeve (more precisely, either at a distance from the winding sleeve, i.e. outside the laying width, or within the range of the laying width) in order to fix the start of the thread to the winding sleeve. If such a fixed winding is arranged outside the laying width on the winding sleeve, the thread must be guided axially into the range of the laying width before the actual winding process. This is achieved by means of a so-called reserve winding. The reserve winding (Reservewicklung) is understood as: a winding of the wire on the winding sleeve, which winding bridges a gap between a fixed winding arranged outside the laying width and the laying width, and in which winding the wire is wound helically on the winding sleeve. Document WO2003/099695a1 proposes a method for operating a winding machine, in which the spatial position of the crosstalk guide of the crosstalk unit is detected. The detected spatial position is provided to or calculated in the control unit of the winding machine at each instant. On the basis of the identification of the position of the crosstalk guide, individual positions of the crosstalk guide can then be expediently realized (for example with a reduction in the number of revolutions of the counter-thread spindle) in order to take the required measures here in relation to the operation of the winding spindle and to the circumferential speed of the thread being wound on the winding sleeve, in particular to produce a fixed winding and, if necessary, a connected auxiliary winding. As a possible design of the oscillating unit, document WO2003/099695a1 proposes an oscillating unit with a driven counter-threaded shaft (Kehrgewindewelle) and with the usual laying grooves, or also a transmission with rotatable blades. It is also proposed here that, for producing the fixed winding, the rotational speed of the counter-thread shaft is braked to zero if the slip guide occupies the relative position required for producing the fixed winding, spaced apart from the laying width of the winding spindle. In this way, a conventional counter-threaded shaft with a laying groove can be used, whereby an additional arrangement of the groove section without a gradient, the use of a switch and possibly also a reversal of the direction of rotation of the drive of the counter-threaded shaft can be rendered unnecessary. In order to achieve a position of the crosstalk guide outside the laying width in relation to the extension of the laying groove of the counter-threaded shaft, the crosstalk unit can be moved axially by a controllable drive (here by means of a pneumatically operated piston-cylinder unit). The entire crosstalk unit (including its housing) can be moved relative to the machine frame by means of a drive, or only the counter-thread shaft can be moved coaxially in the housing relative to the longitudinal axis of the winding spindle.

Document DE 102012018491 a1 likewise describes a winding machine with two winding spindles held on a turret, which can be pivoted alternately between a winding position and a change position. The wire being introduced should be wound into a spool without significant interruption. At the end of the reel rotation (spulrese), the winding spindle with the completed winding reel is moved into the replacement position, in order to be able to transfer the thread on the one hand onto a new winding spindle guided into the winding position and on the other hand to be able to remove the completed winding reel from the winding spindle held in the replacement position. The end of the thread produced in the transfer of the thread is usually placed on the periphery of the completed spool held in the replacement position. Described herein are the following: i.e. when the winding is removed from the bobbinAnd the loose end of the wire can prove problematic in the transport of the spool. The reasons for this are as follows: the loose end of the wire may become entangled with the device article and the wire may be undesirably pulled from the spool. The document DE 102012018491 a1 is known as follows: a fluid is applied as a securing means for the release end of the thread. The outer coil (windong) of the winding is wetted by the fluid to fix the loose end of the thread. It is considered disadvantageous here that the fluid penetrates adjacent layers of the thread and thus influences the physical properties of the thread. It has furthermore been found that a relatively short fixing effect can only be caused by wetting of the coil. The reason for this is that, in the case of longer storage times, volatilization of the fluid and destruction of the fixing effect result. In this context. Document DE 102012018491 a1 proposes: the loose end of the wire is fixed to the winding of the bobbin by means of a film tape (Folienband). The film tape is wound together with the wire into the last coil of the bobbin. This should avoid: the film tape itself being wound over the end of the thread

After which a slip occurs. In order to fasten the thread ends, the adhesive forces acting between the film layers of the film strips lying on top of one another are then used.

The document DE 102008062161B 3, however, addresses the following problems: the loose end of the wire of the completed spool can accelerate radially outward in the spool still rotating in the replacement position, which is in principle undesirable. In the worst case, the loose end of the wire of the complete bobbin in the replacement position may be caught by an empty winding sleeve in the winding position or by any catching means, whereby this loose end may interfere with the starting winding process to the next bobbin in the winding position. Document DE 102008062161B 3 proposes the use of a separating device which provides a partition wall between the bobbins, which is arranged in the region between the winding position and the replacement position. The separating wall of the separating device should prevent the loose end of the thread from being transferred from the bobbin in the region of the change position to the bobbin in the region of the winding position.

Document EP 1627840 a1 is directed to the fixing of the free ends of the yarn wound into a spool, wherein the spool is configured in this case as a spool (Garnwickel), spool (Bobine) or cocoon shaft (Cocon) for creating embroidery with the aid of an embroidery machine or for creating decorative pattern stitches with the aid of a quilting machine. In such a spool, the start of the wire extends from the inside of the winding. The thread spool is placed into the shuttle of the embroidery or quilting machine, wherein the beginning of the thread extending therefrom is subsequently threaded through the different eyelets of the shuttle. The free, outer end of the wire is usually pulled under the previous loop of wire ("under-wound") and then cut. In contrast, document EP 1627840 a1 proposes that the free ends of the thread be fixed to the outer circumferential surface of the thread spool in a material-locking manner (in the case of meltable threads, in particular by means of gluing or welding). In such embroidery or quilting machines, the yarn is pulled out from the spool starting with the yarn built in. Thus, as the inner peripheral surface of the spool shaft gradually moves outward, the yarn is taken out from the spool from the radially inner portion toward the radially outer portion.

In contrast, document GB 454555B proposes that the free ends of the wire be fixed to the outer circumferential surface of the winding by means of pushpins.

Different embodiments of the crosstalk unit are known for guiding the thread during the rotation of the spool:

document WO 2009/103095 a1 discloses a crosstalk unit in which the movement of the crosstalk guide is caused by a linear motor. The series unit has a stator including a guide rail, in which a winding generates an electromagnetic field. The moving series guide of the series unit has permanent magnets, which thus form the rotor of the linear motor. The play guide is guided on the guide rail of the stator by rollers.

Document WO 2000/24663 a1 also discloses a crosstalk unit in which a crosstalk guide, which is pivoted here in the form of a finger, is driven by a linear motor.

Document EP 0453622 a1 discloses a crosstalk unit in which the crosstalk guide can be axially moved back and forth by means of a belt drive.

Document DE 2643421 discloses a winding machine in which a counter-threaded shaft is used in the oscillating unit. The axial position of the counter-thread shaft is changeable over a determined stroke by means of a cylinder. The counter-threaded shaft is driven by a motor that is controllable in its rotational speed and reversible in its rotational direction. The counter-thread shaft has, in addition to the conventional laying trough, a trough section without a gradient into which the play guide is guided by reversing the direction of rotation of the counter-thread shaft. Switching in the slope-free trough section can be achieved: the running guide is combined with a renewed reversal of the direction of rotation, so that a laying groove for the thread spool on the winding sleeve is realized. Here, a winding sleeve with a collection area is applied. In the case of automatic bobbin replacement, the rotational speed of the counter-threaded shaft is first reduced to a value that is advantageous for forming the wire reserve, and the wire continues to be wound on the bobbin at a reduced speed. The play guide is transferred into the groove section without slope by reversing the direction of rotation introduced subsequently. Subsequently, an axial displacement of the counter-thread shaft is effected with a stroke determined by the cylinder, so that the thread can reach the catching region of the empty sleeve. After the trapping has been achieved in the trapping region of the empty sleeve, a wind-up start probe is operated to return the operation of the counter-threaded shaft by means of the cylinder back into the initial position.

Document JP S62-105871 a discloses a bobbin on which a partial section of a band-shaped winding (which partial section is disposed in front of the end of the winding) is wound with a plurality of coils with a small lateral offset. The end is then pulled by the driving rod under the lowermost turn of the partial section of the winding which is disposed forward of the end, so that the end and the lowermost turn cross one another underneath. Thus, the fixation of the tip is achieved by: the end of the wrap is trapped between the circumference of the bobbin and the lowermost coil.

Disclosure of Invention

The aim of the invention is to provide a bobbin with a winding of a tape winding (WickLung), wherein the ends of the winding are fixed alternatively or in an improved manner. The object of the invention is to provide a winding machine or a method for winding bobbins, by means of which correspondingly modified or improved bobbins can be produced. Finally, the object of the invention is to provide a software product with control logic for carrying out a correspondingly improved method and/or a control unit for a winding machine.

According to the invention, the object of the invention is achieved by the features according to the invention. Further preferred embodiments of the invention are known from the preferred embodiments.

The bobbin according to the present invention has a winding of a tape winding (also referred to as a "winding assembly"). Here, the invention encompasses any type of spool, in particular:

bobbins without or with a winding sleeve (Spulenhuls);

a spool of any length and/or of any inner and/or outer diameter;

a bobbin having an arbitrary geometry of an outer peripheral surface (particularly a cylindrical peripheral surface or a tapered peripheral surface);

a spool having any wound form according to DIN-ISO 5238; and/or

A bobbin with an arbitrary winding pattern.

To name just a few non-limiting examples: the bobbins may be configured as cylindrical crosshairs, sun bobbins, cylindrical crosshairs with oblique end sides, keg bobbins, conical crosshairs with straight end sides, conical symmetrical crosshairs, conical asymmetrical crosshairs, disc bobbins, foot bobbins, sewing thread bobbins, cop bobbins or glass fiber rovings (see for this reference "Handbuch der Spultechnik",1. aufiage, Georg Sahm GmbH & co. kg Maschinenfabrik, Postfach 1740, D-37257 eschwe).

According to the invention, it is known to fix the ends of the windings according to the prior art:

according to DE 102012018491 a1, by means of a fluid-through material-locking manner;

according to document EP 1627840 a1, by means of adhesive bonding or by means of welding; and

according to document GB 454555B, by means of drawing pins or film strips

Are costly because additional consumable components (i.e., fluid, film tape, adhesive, or pins) must be fed to the winding process. Furthermore, with such a fixing device, mechanical damage and contamination of the ends of the windings and adjacent layers of the winding of the bobbin can occur. Finally, these securing measures require the removal and removal of the securing means when the wrap is removed at the user.

It is surprising that according to the invention a fixing of the end of the winding is proposed, which can completely eliminate the additional fixing means (wherein, naturally, it is not excluded that, in addition to the following measures according to the invention, additional fixing means can also be applied cumulatively):

according to the invention, the end of the wrap is fixed frictionally and/or positively on the partial region of the wrap that is disposed upstream of the end. A fixation is thus achieved directly between the end of the wrap and the partial region of the wrap that is disposed forward of the end. This is achieved without additional fixing elements. This is achieved, more precisely, by the friction forces caused between the ends of the windings and the preceding partial regions of the windings and/or by a form-fit in the region of the lateral recess (hinderschneidung) formed by the windings between them. The friction and/or form-locking preferably forms a fastening force which opposes: the force is extracted, in particular radially outwards (i.e. for moving the end of the winding away from the winding) from the end of the winding. According to the invention, no under-wrapping (Unterwickeln) or under-crossing (Unterkreuzen) or knotting of the ends of the windings takes place either. The end of the winding is preferably the end region of the winding of the spool which is provided last to the spool and which is removed first from the spool at the user.

According to the invention, the winding forms a wound ring on the outer circumference of the winding of the bobbin. The loop can be formed by a single layer (formed by the coil of the winding), preferably at least two or more layers of winding. Such a ring forms an axial end face on which the end of the winding is supported in a frictional and/or form-fitting manner. Preferably, the end of the winding is elastically compressed or clamped in the axial direction by means of the axial end side. It is also possible here for this elastic compression and clamping to be achieved by bending (durchbieggun) the cross section of the tape winding. Thus, the elastic compression or the pressing onto the axial end side can be caused by the elastic resistance of the band winding with respect to such bending. In order to achieve such a tightening, compression or clamping on the axial end face of the ring, the band winding can then be additionally supported on the other side. Such additional support can be realized, for example, on a limiting plate (begrenzungssceibe) on the circumference of the bobbin, on an end-side disk (Teller) and the like.

With an alternative solution of the invention, the winding forms two wound rings on the outer circumferential surface of the winding, the two wound rings having axial end sides facing each other. The ends of the winding are supported between these axial ends in a friction-locking and/or form-locking manner. Preferably, the ends of the windings are trapped between these axial end sides (gefangen), clamped, elastically fastened, elastically compressed and/or elastically bent in cross section.

In a further embodiment of the invention, the axial end faces of the rings have an axial spacing which is smaller (at least in some regions) than the width of the tape winding. This may only be the case over part of the circumference of the spool. Preferably, however, this applies to the entire circumference of the spool. If the windings are introduced (in particular "pulled in") into the gap between the axial end sides for such a measured dimension of the spacing of the axial end sides of the rings, it is necessary to reduce the width of the band-shaped windings, which reduction can be achieved in particular by elastic deformation and/or bending of the cross section of the windings.

In principle, any design of the ring is possible. According to the invention, one or more of the loops has at least two layers (formed by the coils of the winding) of a tape winding. In particular, the axial end face of the ring can thus be designed in the form of a circular ring, the thickness of the circular ring corresponding to the product of the thickness of the band winding and the number of layers of the ring wound one on top of the other.

There are several possibilities for the design of the axial extension of the at least one ring. It is thus absolutely possible for the loop to be wound with an axial feed on one end side or to be reciprocated or with a "loop lay width". In this case, however, the loop lay width corresponds in any case to a fraction (in particular less than one tenth, one twentieth, one fiftieth or one hundredth) of the lay width of the windings of the bobbin.

Particular proposals for the present invention are: the ring(s) has an axial extension which is less than twice the width of the tape winding. This means that: the winding is not laid in any way with coils next to one another, but rather is always wound directly onto a previously wound coil in the region of the loop. For the theoretically smallest superposition, the axial extension of the ring (with clearance considerations) corresponds to twice the width of the band winding. At the other extreme, this may absolutely be a preferred design: the coils are wound with complete mutual overlap, so that the axial extension of the loops corresponds exactly to the width of the band winding. Between these two extremes, the ring may have any axial extension.

If adjacent layers of such a ring are wound only partially on top of one another, the ring (or the rings) can have two partial rings which can be arranged axially offset from one another by a V. In this case, the two partial rings can each be formed in a single layer or in a plurality of superposed layers without or with an offset. Due to the offset V, the axial end side of the ring for fixing the end of the winding is formed in a stepped manner. The stepped axial end face enables: the gap delimited by the axial ends for inserting the ends of the windings (preferably the gap between the two rings) is of the undercut type, into which the ends of the windings can be inserted (with or without axial pretension), thus ensuring a form-fitting fastening. In order to pull the end of the winding out of the bobbin for the state of being inserted into the undercut in this way, the end of the winding must then be guided through the undercut, for which purpose this must be oriented purposefully and appropriately, or this must also cause a deformation of the winding, thereby producing an improved fixing effect for the rear end.

There are many possibilities for the choice of the offset V within the scope of the invention. In principle, the size of the undercut can be increased with increasing offset V, so that the fixing effect can thereby be increased. On the other hand, an increase in the size of the offset V may however also have the disadvantage: that is, introduction of the end of the wrap becomes difficult. This may be a target conflict. For the embodiments of the present invention, it has proved advantageous: the offset V is in the range of 0.1 to 0.4 times the width B of the tape wrap (preferably in the range of 0.2 to 0.3 times).

The rings and the sub-rings may have the same or different thicknesses. Preferably, the built-in partial loops of the two loops, which are directly wound onto the winding, have different thicknesses. Although the two rings in this case form lateral recesses in the transition from the inner partial ring to the outer partial ring, the introduction of the ends of the windings into the gap between the two rings can be simplified due to the different thicknesses.

There are many possibilities for the spacing of the axial end sides of the ring. With the inventive embodiment, the axial end sides of the loops (at least in partial regions, which can be formed, for example, by partial loops) have a mutual spacing which corresponds to the product of the width B of the tape winding by a factor. Here, the coefficient is in the range of 0.50 to 0.98, preferably in the range of 0.60 to 0.95, or 0.70 to 0.90.

In a method for solving the task of the present invention, a winding for winding a tape winding is first wound. Subsequently, two loops of the winding are wound on the winding. Here, the two rings are wound with a gap on the axial end side of the rings, which is smaller than the width B of the tape winding. Finally, in the method, the winding is introduced into the gap formed between the axial end faces, thereby ensuring that the ends of the winding are positively and/or frictionally fixed.

In a further embodiment of the method, at least one ring is wound with two partial rings, wherein the partial rings are wound with an axial offset V, by means of which the aforementioned undercut can be provided.

For winding the two rings into two partial rings with a spacing and/or one ring into two partial rings with an axial offset V, the crosstalk unit is preferably actuated accordingly in the method according to the invention, i.e. for winding the two adjacent rings, the crosstalk unit is first moved into the adjustment region for the first ring and then into the adjustment region for the second ring, bridging the spacing of the rings. Accordingly, for winding the partial ring with an axial offset, the actuation of the oscillating unit can be realized in such a way that: the first partial ring is first wound in the first setting position of the oscillating unit, and the oscillating unit is then moved by the offset V, with the second partial ring being wound.

It is possible to first break the winding (Durchtrennen) and then introduce the free end of the winding into the gap formed between the axial end sides. In a preferred embodiment of the method according to the invention, the windings are first introduced into the gaps between the rings in the not yet broken state, whereby a form-locking and/or frictional fixing of the ends of the windings is then ensured. Subsequently, the winding is then disconnected.

In principle, the use of the method according to the invention and thus the production of the bobbin according to the invention can be carried out on any winding machine. The method can thus be used on a winder head of a winder having only one winding spindle. With the method according to the invention, however, use is made of a winding head of a winding machine, in which case two winding spindles are held on a turret, which can then be used alternately for winding the spools. In this method, the winding and the ring are first wound in a winding position in which the winding spindle is held on the turret. Subsequently, the winding spindle is moved out of the winding position, in particular in the direction of the change position or into the change position, by rotation of the turret. Subsequently, the end of the winding is then introduced into the gap formed between the axial end sides of the ring and/or the winding is broken away from the winding position of the winding spindle (abseits).

According to a particular proposal of the invention, the winding is additionally supported on the holding device and/or the guide device after being introduced between the rings into the gap formed between the axial end sides. This may be in particular

During rotation of the turret holding the winding spindle; and/or

In the winding object stringThe guide is moved to trap the winding in the area of the other winding spindle; and/or

The situation during the manufacture of the stationary winding and/or the spare winding on the other winding spindle. By means of such a holding device and/or guide device, for example, the end of the winding (despite possible rotation of the turret and/or possible movement of the winding crosstalk guide) can be prevented from moving out of the ring. It can be advantageous here for the winding to be supported on a holding element or receptacle of the holding device and/or the guide device in such a way that: despite the possible rotation of the turret and/or the movement of the winding crosstalk guide, the contact position between the winding and the holding element or the receiving portion is not changed.

There are a number of different possibilities for the construction of the holding device and/or the guiding device. For example, the holding device and/or the guide device can be designed as a holding rod and/or as a holding hook. It is also possible to integrate a separating device for severing the winding in the holding device and/or the guide device, wherein the separating device can be operated separately for severing or can be automatically severed as the stress in the winding increases.

Another solution to the object of the invention is to provide a winding machine which can be constructed in principle according to the construction known from the prior art. For example, the winding machine can have at least one winding spindle, a turret, a pressure roller and/or a crosstalk unit. According to the invention, a control unit is provided in the winding machine. The control unit has control logic, by means of which a method of the type described above can be executed.

It is possible that a conventional winding machine is retrofitted by reprogramming of the control unit, in particular by means of driving in a modified manner:

drive for a string-up unit and a winding spindle for producing rings, sub-rings, offsets, and for winding up a coilInserting a winding into the gap between the axial end sides of the rings; and/or

A turret.

It is also possible for the winding machine to have, with the same structural design or with only minor structural changes:

sold in a configuration in which the fixing of the ends of the windings according to the invention is not effected; and

sold in a modified form of construction in which the fixing according to the invention of the ends of the windings is possible.

In order to be able to achieve this, a further solution to the task of the invention then proposes a software product having a control logic (Steuerlogik) designed to be suitable for carrying out the method in the manner described above and/or a control unit determined for the winder. With the aid of such a software product, it is then possible to enable the winding machine to carry out the method according to the invention and/or to enable existing winding machines to be retrofitted or "reprogrammed".

Advantageous developments of the invention result from the preferred embodiments, the description and the drawings. The advantages of the features and of the feature combinations described in the description are merely exemplary and can be used alternatively or cumulatively without the necessity of implementing these advantages by means of embodiments according to the invention. The disclosure regarding the original application documents and patents thus applies, without thereby altering the subject matter of the appended claims, as follows: additional features can be gathered from the figures, in particular the geometry shown and the relative dimensions of the various components with respect to one another and their relative arrangement and effective connection. Features of different embodiments of the invention and combinations of features of different claims are also possible in the selected reference relationships differing from the claims and thus provide an improved motivation. This also relates to features shown in the individual figures or mentioned in the description thereof. These features may also be combined with the features of different claims. Features which are likewise cited in the claims can be omitted for further embodiments of the invention.

The features mentioned in the claims and in the description may be understood in relation to their quantity in such a way that there is a quantity which is exactly this quantity or greater than this quantity, without the adverb "at least" being explicitly applied. Thus, for example, if reference is made to a (single) subring, this is to be understood as meaning that there is exactly one subring, two subrings or a plurality of subrings. These features may be supplemented by other features or be the only features that make up the corresponding result.

The inclusion of reference signs in the claims does not limit the scope of the claimed subject matter. The reference signs have been included for the sole purpose of streamlining the understanding of the claims.

For winding the bobbin 2, a winding 3 is provided discontinuously or preferably continuously, which winding 3 is a band winding. The winding 3 is fed to the bobbin 2 by means of a device for influencing and maintaining the stress of the winding 3 constant, in particular a deflecting roller 5 with an associated adjusting arm 6, and by means of a whipping unit 7. The winding machine 1 has a winding spindle 8, a winding sleeve 9 is pushed onto the winding spindle 8, and a winding 10 of the winding 3 is wound around the winding sleeve 9. However, it is also possible to carry out the winding without using the winding sleeve 9. The bobbin 2 is formed here by means of a winding sleeve 9 and windings 10. The driving of the spool 2 can be achieved by the driving of the winding spindle 8. It is also possible to drive the bobbin 2 by means of a drive roller (antitiebswaze) which presses against the winding circumference 11 and frictionally engages the winding 10 and thus the bobbin 2 in rotation.

The oscillating unit 7 has a winding oscillating guide 12, which winding oscillating guide 12 is moved parallel to the longitudinal axis of the winding spindle 8 by controlled driving of the oscillating unit 7. The winding 3 is moved by means of a winding path guide 12, wherein the axial position of the winding path guide 12 caused by the actuation of the winding path guide 12 can be predetermined: in which axial region of the winding spindle 8 and the winding 10 the winding 3 rests on the circumferential surface 11 of the winding 10.

Fig. 1 shows a winding machine 1 with a bobbin 2 at the end of the bobbin revolution. This means that: the winding 10 has been completely wound, wherein the winding 10 has achieved its normal diameter and a predetermined length of the winding 3 has been wound into the winding 10. Furthermore, on the circumferential surface 11 of the winding 10, winding is achieved in which the

loops

13, 14 of the winding 3 have a spacing 15. In the gap 16 between the

rings

13, 14, the end 17 of the wrap 3 is then inserted. The end 17 of the wrap 3 is fixed in the gap 16 only by interaction with the

loops

13, 14, i.e. the section of the wrap 3 preceding the end 17. Since the endless winding 3 has not yet been broken in the state shown in fig. 1, the end 17 of the winding 3 inserted into the gap 16 between the

rings

13, 14 is not yet free and has not yet been separated from the winding 3 which is still being fed in.

Fig. 2 shows a detail II of the bobbin 2. It is particularly visible here that the spacing 15 of the

loops

13, 14 is slightly smaller than the width B18 of the wrap 3.

Fig. 3 and 4 show a winding machine 1, in which two winding

spindles

8a, 8b are held on a turret 19. The turret 19 is rotatable about a central axis of rotation which is oriented parallel to the longitudinal axis and the axis of rotation of the winding

spindles

8a, 8 b. The winding

spindles

8a, 8b can be realized by rotation of the turret 19:

transitioning to a winding position in which the spool is wound; and

in a change position in which the completely wound spool can be removed from the winding spindle, a new winding sleeve can be placed on the winding spindle if necessary, and so on.

It is possible that in the change position, or during the rotational movement between the winding position and the change position, the winding 3 is caught by means of the catching

devices

23a,23b of the winding

spindles

8a, 8b or by means of the empty winding

sleeves

9a, 9 b. For this purpose, the wrapping running guide 12 can be in a running position in which the wrapping 3 is suitably supplied to the

trapping devices

23a,23 b. It is possible here for this position to be outside the usual laying width (i.e. axially before or after the winding 10). What should be avoided here is: this movement of the winding-material running guide 12 not only displaces the winding material 3 in order to trap it on the empty winding-up sleeve, but also leads to an axial displacement and/or a changed orientation of the winding material 3 in the region of the end 17 between the

rings

13, 14 of the completely wound bobbin 2. This avoidance thus ensures that: that is, the winding 3 is guided on the way from the completed winding spool 2 to the empty winding spindle 8b by the holding and/or guiding

device

20a, 20 b. For the embodiment shown, there are two holding and/or guiding

devices

20a, 20b, which are each configured as a

guide rod

21a, 21 b. The

guide rods

21a, 21b have

receptacles

22a, 22b in the axial region in which the release end 17 of the winding 3 is inserted into the gap 16 between the

rings

13, 14 of the completely wound bobbin 2. The receiving

portions

22a, 22b may be, for example, arches, projections, indentations, retaining tabs, or the like. As can be seen in particular in fig. 4, the

receptacles

22a, 22b can also be configured as L-shaped arches, wherein one side of the L extends radially outward from the

guide rods

21a, 21b, while the other side of the L extends parallel to the longitudinal axis of the

guide rods

21a, 21b (i.e. away from the catching

devices

23a,23b for catching the winding 3 on an empty winding sleeve). The winding of the spool 2 on the winding spindle 8a takes place at a position differing from that of fig. 3, for example at the 12 o' clock position (winding position) of the winding spindle 8a on the turret 19. In this winding position, the holding and/or guiding

device

20a, 20b does not interact with the winding 3, so that the winding 3 reaches directly from the winding streaming guide 12 to the circumferential surface 11 of the winding 10. Fig. 3 and 4 show the winding machine 1 from the winding position into the change position during a clockwise rotation of the turret 19. This rotation facilitates the interaction of the winding 3 with the holding and/or guiding

devices

20a, 20b, i.e. against the circumference of the

guide rods

21a, 21b, wherein the circumferential angle of the abutment of the winding 3 against the circumference of the

guide rods

21a, 21b becomes greater with increasing rotation of the turret 19. If the winding spindle 8b is in the winding position at the end of the rotation of the turret 19 and the winding spindle 8a with the spool 2 arranged thereon is in the change position, the winding 3 must interact with a catching device 23b, wherein this catching device 23b is arranged, for the exemplary embodiment shown, in an axial region of the winding spindle 8b or of the winding sleeve 9b, which axial region is arranged on the side facing away from the turret 19 before the laying width or before the winding 10. Thus, the winding play guide 12 moves into an axial region outside the laying width. This movement of the winding crosstalk guide 12 contributes to: the angle of the winding between the winding crosstalk guide 12 and the receiving portion 22b of the holding device and/or guide device 20b is changed, while the position and orientation of the winding 3 between the receiving portion 22b and the spool 2 is unchanged. In this way it is ensured that: the loose end 17 of the wrap 3 does not "pull out" from the gap 16 between the rings 13, 14 (despite the movement of the wrap crosstalk guide 12). If the receptacle 22 is formed as an L-shaped bow as described above, the axial movement of the winding crosstalk guide 12 causes the winding 3 to turn in the radially oriented side region of the L. If the winding 3 is subsequently caught by the catch device 23b in the region of an empty winding spindle 8b, a bobbin revolution can be started on this winding spindle 8 b.

The breaking of the winding 3 is achieved by separate separating means. It is also possible for the severing of the wrap 3 to take place in the region of the holding device and/or the guide device 20, for which purpose separate separating means may be present here. It is also possible to cause a disconnection in the region of the holding device and/or guide device 20 (possibly at the respective knife edge of the holding device and/or guide device 20) by means of an increase in the stress in the wrap 3.

After the winding 3 is broken, a large part of the separated winding 3 is wound into the winding 10 of the completed bobbin 2 which has completed the winding. The partial section of the winding 3 connected to the winding 10 forms the loop 13, while the further following partial section of the winding 3 forms the loop 14. Subsequently, as a further partial section, an end 17 of the wrap 3 follows, which end 17 is pulled into the gap 16 between the

rings

13, 14 and is fixed there and has a remaining partial section which extends out of the gap 16 between the

rings

13, 14 in a releasable manner.

Fig. 5 shows a detail of the fixing of the end 17 of the winding 3 on the bobbin 2:

the winding 3 is wound in

loops

13, 14, which

loops

13, 14 have a spacing 15. The ring 13 has hereTwo sub-rings 24,25, which sub-rings 24,25 are wound on top of one another. The sub-ring 24 has a thickness D₂₄And the sub-ring 25 has a thickness D₂₅. Preferably, the thickness D₂₄Greater than thickness D₂₅. The sub-ring 25 is offset relative to the sub-ring 24 in the direction of the other ring 14 by an offset V26. The partial rings 24,25 are produced as directly interconnected, intertwined partial sections of the winding 3. In the sub-loops 24,25, a plurality of layers (in particular more than two, five, ten, twenty or even more than 50 layers) of windings 3 are wound on top of each other. For the embodiment according to fig. 5, the ring 14 is not formed with different partial rings offset from one another. Rather, all layers of the ring 14 are directly wound onto one another without offset. Preferably, the thickness D of the ring 14₁₄The thickness D of the sub-ring 24 slightly less than the ring 13₂₄. The gap 16 between the

rings

13, 14 is bounded axially by the axial end side 27 of the ring 14 and the axial end side 28 of the ring 13. The axial end 27 of the ring 14 is formed flat as a torus that engages radially inside the circumferential surface 11 of the winding 10. In contrast, the axial end face 28 is formed with a circumferential step 29 on account of the offset 26. In the region of the step 29, the end side 28 forms a side recess 54. The step 29 separates, in the axial end face 28, a first partial ring surface delimited by the partial ring 25, to which the circumferential surface 11 of the winding 10 is radially inwardly connected, and a partial ring surface formed by the second partial ring 24, which is connected radially inwardly, from said partial ring surface. The

rings

13, 14, the sub-rings 24,25, the axial end sides 27, 28 and the above-mentioned ring or sub-ring surfaces all extend in the circumferential direction around the longitudinal axis of the bobbin 2.

In the partial cross section shown in fig. 5, the gap 16 has a substantially U-shaped cross section which is open radially to the outside, the base of the U being formed by the circumferential surface 11 of the winding 10 and the sides of the U being formed by the end sides 27, 28 of the

rings

13, 14. Since the ring 13 is constructed with the two

partial rings

24,25 described above, the side of the U is constructed here in a stepped manner. Furthermore, this side is longer than the straight side of the U formed by the end side 27 of the loop 14.

The end 17 of the wrap 3 is introduced, placed or pulled into the gap 16. Since the distance 15 between the end 27 of the ring 14 and the annular surface of the ring 13 formed by the partial ring 24 at the axial end 28 is smaller than the width B18 of the winding 3, the winding 3 is supported with its ends on the

ends

27, 28 of the

rings

13, 14. The end 17 of the wrap 3 is thereby elastically fastened between the end sides 27, 28, as a result of which an axial contact pressure is produced between the end 17 of the wrap 3 and the end sides 27, 28. This axial pressing force contributes to the friction between the end 17 of the wrap 3 and the end sides 27, 28. This friction creates a resistance to prevent the end 17 of the wrap 3 from coming out of the gap 16.

Additionally, the step 29 of the end side 28 forms a form-locking barrier to prevent the end 17 of the wrap 3 from coming out of the gap 16. Thus, the end 17 of the wrap 3 is positively and frictionally fixed to the spool 2 relative to the

rings

13, 14 for this embodiment.

Fig. 6 shows an alternative embodiment, in which not only ring 13 is formed as

partial rings

24,25, but also ring 14 is formed as

partial rings

30, 31. In this case, the outer partial ring 31 is arranged with an offset V32 in the direction of the other ring 13 relative to the inner partial ring 30, so that the end face 27 also has a circumferential step 33. In this embodiment, the end 17 of the winding 3 is fixed frictionally and positively by axial pressure on the two

end sides

27, 28 and by means of the

steps

29, 33 so as to prevent it from exiting the gap 16.

Examples for dimensioning the

rings

13, 14 are listed below, which are feasible within the framework of the invention, however this should not be a limitation of the invention:

if the

loops

13, 14 are configured without sub-loops, these

loops

13, 14 preferably have a width corresponding to the width B18 of the wrap 3.

If the

loops

13, 14 are configured with

sub-loops

24,25 or

sub-loops

30,31, then these sub-loops each have the width B18 of the wrap 3.

The spacing 15 of the

rings

13, 14 is smaller by a factor x than the width B18 of the wrap 3, at least in partial regions (preferably in partial regions that are radially internal to the case of the application of the partial rings 24, 30). Preferably, the coefficient x is 0.8 ± 10%.

Thickness D of the ring or sub-ring₁₃、D₂₄、D₂₅、D₃₀、D₃₁At least twice as large as the thickness of the windings 3, so that in these rings or sub-rings at least two layers of windings 3 are wound on top of each other.

Preferably, the thickness D₁₃、D₂₄、D₂₅、D₃₀And D₃₁Greater than 0.5 mm, greater than 1 mm, or even greater than 2 mm.

In particular in the case of a wrap 3 having a width B18 of less than 3 mm, as offset V26, 32 between the

partial rings

24,25 or 30,31, an offset V corresponding to one quarter (± 10%) of the width B18 of the wrap 3 is used.

Preferably, a wrap 3 having a width B of less than 3 mm is applied according to the embodiment of fig. 5.

In contrast, the embodiment according to fig. 6 is preferably used for a wrap 3 having a width B of at least 3 mm. Here, however, the measurement of the offset V26, 32 applies in particular also to: the offset is approximately one quarter (± 10%) of the width B18 of the wrap 3.

For the embodiment according to fig. 5, in particular for a wrap 3 having a width B of less than 3 mm, the thickness D of the partial ring 24₂₄Greater than the thickness D of the ring 13₁₃. In contrast, for the embodiment according to fig. 6, in particular for a wrap 3 having a width B of at least 3 mm, the thickness D of the partial ring 24₂₄Greater than the thickness D of the sub-ring 30₃₀。

In order to introduce the end 17 of the wrap 3 into the gap 16 delimited by the end sides 27, 28, in particular the bending elasticity of the cross section of the wrap 3 about a bending axis oriented in the longitudinal direction of the wrap is utilized. This can be applied on the one hand in such a way that a folding or bending type of the cross section of the wrap 3 about the aforementioned bending axis is produced, whereby the end 17 can first be introduced into the narrowing gap 16. The elastic return of the wrap 3 (i.e. the "rebound" of the wrap in such a way that the bending or folding of the wrap 3 in the cross-section shown in fig. 5 and 6 is reduced) causes the end 17 to press on the end side against the end sides 27, 28 of the

rings

13, 14. The step 29 and, if appropriate, the further step 32 form lateral recesses 54, 55 of the gap 16, which ensure a form-locking fixing of the end 17 of the wrap 3 in the gap 16. A form-locking fastening with a certain radial gap can be realized as shown. However, it is also possible for the end 17 of the wrap 3 to rest on the

steps

29, 33 without play or even under elastic pretension in the inserted state in the gap 16.

One possible method for winding the spool 3 is now exemplarily elucidated on the basis of fig. 7:

in method step 34, the winding spindle 8a is transferred into the winding position by rotation of the turret 19. In the next method step 35, the winding 3 can be brought into interaction with the collecting device 23a of the winding spindle 8a or with the winding sleeve 9a arranged thereon, if necessary, by moving the oscillating unit 7, whereby the winding 3 is fixed on the winding spindle 8a or the winding sleeve 9 a. In method step 36, the winding 10 is wound while the winding displacement guide 12 of the displacement unit 7 performs displacement within the laying width. In this case, a desired winding pattern can be achieved both by controlling the rotational movement of the winding 10 (by means of a suitable drive speed of the winding spindle 8a or of the driven pressure roller) and by controlling the movement of the winding displacement guide 12. If the winding 10 is completely built up, the winding of the loop 13 is carried out in a method step 37, wherein the following loops are preferably involved: the ring is arranged adjacent to the end face of the bobbin 7, in the region of which the winding 10 ends. For this purpose, in a method step 37, the winding crosstalk guide 12 on the crosstalk unit 7 is moved into an axial position, which corresponds to the position of the ring 13. If a ring 13 with two

partial rings

24,25 is to be produced, the winding path guide 12 is moved away from the end face of the bobbin 2 by the offset V26 after the production of the partial ring 24. During the winding of the ring 13, the thickness D is measured by the delivered length of the winding or by the number of revolutions of the winding spindle 8 or the spool 2₁₃Or D₂₄、D₂₅And (5) controlling. If the ring 13 is completely wound, winding takes place in a method step 38The winding guide 12 is moved axially away from the end face of the bobbin 2 in such a way that a gap 15 is formed. Subsequently, in method step 39, the loop 14 is then wound, wherein, after the completion of the inner partial loop 30, the winding path guide 12 is moved back again at the offset V32, in the case of two

partial loops

30,31 that are to be wound. After the loop 14 is completed, in a method step 40, the winding crosstalk guide 12 is then moved to the center between the two

loops

13, 14, which results from the stress of the winding 3: the windings rest on the upper edges of the two

rings

13, 14, the cross section of the windings 3 is bent radially inward, and the windings 3 can enter the gap 16 between the end sides 27, 28 of the

rings

13, 14, where they again diverge from one another due to the elasticity of the windings 3. The end 17 of the wrap 3 is thereby secured to the spool 2 by the

rings

13, 14. At the latest (possibly already at an earlier time) in method step 41, the turret 19 is rotated in order to transfer the spool 2 from the winding position to the replacement position and to enable winding on the further winding spindle 8b and possibly on the winding sleeve 9b arranged thereon. In method step 42, the winding 3 reaches into the region of the receptacle 22a of the holding device and/or the guide device 20 a. In the receiving portion 22a of the holding and/or guiding device 20a, the wrap 3 and its end 17 are held in an axial position such that the end 17 is not pulled out laterally or upward from the gap 16 between the

rings

13, 14. In method step 43, the further rotation of the turret 19 with the simultaneous movement of the winding strand guide 12 results in: upstream of the receiving portion 22a, the winding 3 interacts with a collecting device 23b of the winding spindle 8b or of the winding sleeve 9 b. In a method step 44, the winding 3 is then disconnected (for example in the region of the holding device and/or the guide device 20) and the winding of a further spool on the winding sleeve 9b is then effected. The method is then repeated accordingly for the winding of the spool on the winding spindle 8b, as described previously for the winding of the spool 2 on the winding spindle 8a, and so on.

Due to the offset V, the ring 14 according to fig. 5 and the

rings

13, 14 according to fig. 6 have an axial extension which is greater than the width B of the winding 3, i.e. greater than the width B of the winding 3 by the size of the offset V.

Fig. 8 schematically shows the control unit 45 of the winding machine 1. Known in the control unit 45 are:

the angle of rotation of at least one winding spindle 8;

the angular velocity and/or the circumferential displacement of the winding spindle 8;

the position and/or speed of the winding crosstalk guide 12; and/or

The angle of rotation and/or the angular velocity of the turret 19,

this can be achieved by transmitting the respective measurement signals of the sensors via the signal lines 46, 47, 48.

On the basis of this, the control unit 45 controls:

a spindle driver 49;

a crosstalk unit 7; and

a turret drive 50; for performing the above method.

Thus, for example, the control unit 45 effects the required axial adjustment movement of the winding-strand displacement guide 12 in order to produce the

loops

13, 14 in steps and then to introduce the end 17 of the winding 3 into the gap 16, while at the same time the rotational movement of the winding spindle 8 is controlled by the spindle drive 49 by suitable actuation. For this purpose, the control unit 45 communicates (wherein also adjustments shall be included) with the spindle drive 49, the tandem unit 7 and the turret drive 50 via

control lines

51, 52, 53.

The invention should not be limited to the embodiments shown. It is thus absolutely possible for the

rings

13, 14 or the

partial rings

24,25, 30,31 to have a greater width than shown, so that the winding of the

rings

13, 14 can be effected by the reciprocating movement of the oscillating unit 7. It is also possible to introduce a plurality of coils of the end 17 of the winding 3 into the gap 16. The formation of the

rings

13, 14 can also differ from the embodiment shown. In this way, two or more sub-rings can be provided in the

rings

13 and 14 so as to be overlapped with each other. It is also possible for the gap 16 to have an arbitrary contour in the partial cross-section shown, which has arbitrarily formed end faces 27, 28. Thereby, also in case the winding crosstalk guide 12 moves slightly during the winding of the

rings

13, 14, the tapered end sides 27, 28 type can be manufactured, just to name one example. Finally, in the figures, simplified views are selected, in which the transition of the winding, which contributes to the offset V and/or to the spacing 15, is not shown. In practice, to provide the offset V and/or the spacing 15, the winding 3 extends helically or spirally around the circumference 11 of the winding 10 or the circumference of the inner partial ring, whereby virtually no changes are made in the design and technical mode of action set forth according to the invention.

In contrast to the above-described method, it is also possible for the end 17 of the winding 3 to be introduced into the gap 16 between the

rings

13, 14 only after the turret 19 has been rotated and the winding spindle 8a with the completed winding spool has been transferred into the replacement position.

Preferably, the holding and/or guiding device 20 is designed such that the holding and/or guiding device 20 prevents the winding 3 on the completed spool 2 from moving axially only in the axial direction in the direction of the catching means 23a,23 b. Preferably, the holding device and/or the guide device 20 or the holding means provided on the holding bar and/or the guide bar 21 are configured to hold a hook.

In the case of a winding machine 1 having a pressure roller and/or an abutment roller for driving the bobbin, which abuts the winding 3 against the circumferential surface 11 of the winding 10, the pressure roller or the abutment roller is preferably moved away from the circumferential surface 11 of the winding 10 before the

rings

13, 14 are wound.

It is possible that the insertion of the end 17 of the winding 3 into the gap 16 is caused by a rotation of the winding 10 about the axis of rotation or longitudinal axis of the winding spindle 8. However, it is also possible for the introduction of the end 17 to be caused at least partially by a rotation of the turret 19 relative to the crosstalk unit 7.

As the crosstalk unit 7, any crosstalk unit known per se can be applied within the framework of the invention. For example, a prior art oscillating unit with a linear motor according to the above can be used, in which the setting up of the

loops

13, 14,

partial loops

24,25, 30,31, offsets 26, 32 and gaps 15 is produced by suitable electrical loading of the linear motor and by the resulting movement of the winding oscillating guide. For example, it is also possible, in particular, to use a prior art oscillating unit with a counter-thread shaft as described above, in which the setting up of the

rings

13, 14 and the

partial rings

24,25, 30,31 in the region of the grooves of the counter-thread shaft is effected as the counter-thread shaft is braked to speed zero, and the

offsets

26, 32 and the gap 15 are produced by rotation of the counter-thread shaft. However, it is also possible to axially displace the entire tandem unit with the counter-threaded shaft or only the counter-threaded shaft by means of a drive (in particular a piston-cylinder unit) for the purpose of establishing the

rings

13, 14, the

partial rings

24,25, 30,31, the

offsets

26, 32 and the gap 15.

Preferably, for tape windings with a thickness of less than 0.3 mm, the following embodiment is used: in this embodiment, the

rings

13, 14 are wound without being offset. With such a tape wrapping, the ends of the wrapping are "clamped" in the region of their two edges on the two

rings

13, 14 and are thus held in a friction-locking manner. In contrast, the following configuration of the loops is applied for a tape wrap having a thickness of 0.3 mm or more: with an offset in the region of one ring or with an offset on both rings, respectively.
