Definitions
- the invention relates to a method for connecting ends of at least two threads, which are arranged to overlap in particular with thread end regions and are then connected to one another.
- the individual threads of a layer are often very close to each other, which means that there is hardly any space available for handling the threads and creating the individual connections.
- This situation exists, for example, when an end of a warp thread layer, as used in weaving machines, is connected to the start of a new warp thread layer.
- two thread ends are conventionally linked to one another by a knot.
- the knotting machines provided for machine knot production require a relatively complex and complicated mechanical construction.
- the knots are usually much thicker than the sum of the diameters of the two threads. This can be problematic in the further processing of the threads, for example when pulling the connected threads through weaving harness elements.
- a further method for producing a compound has become known from EP 0 989 218 AI. It is proposed here to first arrange the two thread ends overlapping next to one another, to pinch them and then to wind them helically around one another. The latter is to be carried out by means of a sleeve or two rollers, each rotating and additionally moving along the threads. Due to friction, the two thread ends should be wrapped around each other. A liquid adhesive is then to be applied to the thread ends thus prepared, with which the thread ends are fixed in the position described.
- this method has the disadvantage that the thread ends are subjected to very high mechanical loads. This can be problematic in particular in the case of threads which consist of several filaments. The same applies to threads that tend to break.
- connection of an entire thread layer with threads of another thread layer takes a very long time and that machine parts are soiled by the application of the adhesive.
- connection of an entire thread layer with threads of another thread layer takes a very long time and that machine parts are soiled by the application of the adhesive.
- the filament composite of the threads is loosened in the thread end areas and filaments of the two thread ends are connected to one another by swirling.
- this method has the disadvantage that it can only be used to connect threads which are constructed as multifilaments. Such a method is evident, for example, from DE-OS 28 10 741.
- the invention is therefore based on the object of providing a possibility for the mechanical connection of threads, in particular of thread ends, which mechanically stresses the threads in the connection area as little as possible despite a high tensile strength.
- the connection area should have a thickness that is as small as possible, so that the connected threads can be easily further processed.
- the method according to the invention should also be able to be used as universally as possible, that is to say it should be suitable both for the connection of threads constructed as monofilaments, as multifilaments or as a fiber composite.
- the connection of the threads should be created within a time be bar that allows an economical use of the method and a device for producing the connection.
- the object is achieved in a method of the type mentioned at the outset in that an aid is passed around the thread end regions abutting one another several times, the aid remaining on the thread end regions.
- the object is also achieved by a device for connecting ends of at least two threads, which is provided with a holding device for holding threads which overlap with their end regions, a connecting device with which the arranged in the holding device Thread end regions are connected to one another, in which an aid can be guided around the thread end regions several times by the connecting device.
- the aid it is preferred to supply the aid to the threads in a gas or air stream.
- the same or one or more further air streams should then be used to wind the aid around the threads to be connected.
- the air flow should give the aid an at least substantially predetermined direction of movement through which the aid moves around the threads. This is preferably done by means of one or more air vortices running or directed around the thread ends.
- a device for this can have one or more air swirl chambers, in which preferably at the same time on the same Chen threads a connection can be generated.
- Such an embodiment is particularly inexpensive, especially because of the few, in particular the few, non-moving components, and is also reliable against functional failure.
- a preferred embodiment of a device can provide a feed means with which the aid receives at least one movement component during its feed movement which runs transversely to the orientation of the threads to be connected.
- a favorable embodiment of such a feed means can have a thread weft nozzle with which the aid is fed to the threads only using compressed air.
- the aid also has a movement component that runs parallel to the orientation of the threads to be connected, which they assume in the area of their connection point. This component of movement can be imparted to the aid as soon as it is supplied or only during an actual winding process in which the aid is then guided around the threads.
- An air flow is preferably used for the winding process, which moves helically around the threads due to the geometric shape of an air swirl chamber and a direction of introduction of the air flow into the air swirl chamber.
- the device can have at least two chambers, in which air vortices preferably flow independently of one another.
- the two chambers can be arranged directly next to one another and separated from one another by separating means. It has proven expedient if the air vortices of the chambers are oriented in opposite directions. This can be achieved through appropriately oriented inlet ducts for compressed air.
- both the direction of rotation of the air vortices and theirs Longitudinal movement component, in a direction parallel to the threads be opposite.
- the invention is therefore based on the idea of arranging the end of one thread and the beginning of another thread overlapping one another.
- the two overlapping thread end areas are preferably slightly tensioned and aligned essentially in a straight line and parallel to each other.
- a windable, longitudinally stretchable, and preferably also flexible, aid such as a yarn, is passed around several times. So that the properties of the connection can be influenced, the aid should not be an original component of the threads to be connected.
- the aid can therefore also differ from the threads in terms of its material. According to the invention, the aid can be fed to the threads and then guided around them.
- Moving around the common circumference of the two thread end areas can be done in different ways.
- These multiple turns result in a winding, wherein the winding can have turns with the same and opposite sense of rotation as well as a plurality of layers of turns arranged one on top of the other.
- the result of moving the aid around according to the invention can thus not only be understood to mean a structure consisting of a yarn with a certain number of helical turns.
- the aid can be handled particularly easily during driving around, if it is preferably in a fixed or in is in a transition state to a liquid physical state.
- the yarn can itself be subject to at least slight tensile stress during the creation of the connection.
- a simple handling of the aid during the production of the connection and still a high load capacity can advantageously be achieved if the tensile load of the aid is increased after or before the wrapping process has ended and this tensile load remains permanently on the aid.
- a yarn can be suitable as an aid, which under certain influence, e.g. Heat or cold, shrinking or contracting.
- An example of yarns with such properties are yarns with at least a proportion of polyamide.
- an elasticity of an aid can also be used to create the connection. It can be provided here that the aid, which is under relatively high tension, is arranged around the two threads, but initially at a distance from them. For this purpose, the aid can be arranged on spacers. If you then remove the spacers, the aid gets onto the threads due to the tension and its elasticity and compresses them. Since part of the tensile stress can be lost again here, aids, for example an elastic yarn with a correspondingly high elastic elongation, should be arranged on the spacer.
- connection aid for example, the yarns with the names Lycra (trademark of DuPont, Geneva, Switzerland) or Dorlastan (trademark of Bayer AG, Leverkusen, Germany) can be used.
- Lycra trademark of DuPont, Geneva, Switzerland
- Dorlastan trademark of Bayer AG, Leverkusen, Germany
- the tensile load on the aid can lead to a compression of the wrapped thread ends.
- This pressure exerted on the thread ends is one of the interrelationships which are responsible for the tensile strength of the connection according to the invention.
- An increase in the tensile load of the aid can therefore be accompanied by an increase in the tensile strength of the connection.
- the thread ends are compressed more with a higher tensile load of the aid, which in turn can lead to a smaller thickness of the finished connection.
- auxiliary device In addition, if the auxiliary device is subjected to a greater tensile load, it will be pressed into the thread end areas, which can also result in a positive fit between the auxiliary device and the two thread end areas. A frictional connection between the two threads to be connected can also contribute to the strength of the connection.
- an adhesive is additionally applied.
- the primary purpose of this adhesive or adhesive is to strengthen the connection between the aid mentioned and the thread end regions.
- the adhesive is already contained in the auxiliary itself.
- a first and particularly preferred example of this are so-called combination melt adhesive yarns.
- Such yarns have two components. While one component is a thin chemical fiber thread, the other component can be a hot melt adhesive that develops its adhesive properties when heated.
- Combined melt adhesive yarns based on polyamide are particularly preferred. When these yarns are heated, not only does the adhesive portion melt, to then connect to the threads.
- the polyamide component contracts at the same time as the melting process, thereby creating a tensile force in the yarn and a compressive force in the threads.
- a contractional connection is produced by the contraction and, on the other hand, an adhesive and / or an integral connection is produced by the adhesive.
- the at least one heating process can thus be used advantageously in a number of ways.
- Such an adhesive connection can also be subjected to a permanent tensile load and thus increases the tensile strength of the connection resulting from the wrapping.
- an adhesive connection can provide that the auxiliary is covered or soaked with an adhesive during the feeding to the thread ends. During or after the thread ends have been wrapped with the auxiliary, the adhesive can then develop its adhesive effect by drying or curing.

- Fig. 1 one end of a partially shown warp thread layer 1, as used in weaving machines, is shown in a highly schematic manner.
- the warp threads 2 are clamped in a frame 3.
- a thread end 4 of a new warp thread layer 5 is to be added to the ends of the threads 2 of the warp thread layer end.
- the device according to the invention shown in FIGS. 2 to 8 is provided for the production of such thread connections.
- it has an air swirling device 6, into which a multi-melt adhesive yarn 8 to be removed from a yarn spool 7 and provided as a connecting aid is introduced via a thread weft nozzle 9.
- the yarn offered by the company Ems-Chemie AG, Domat / Ems, Switzerland, under the name GRILON C-85 (with a yarn strength of 2000 dtex) is used as the combination melt adhesive yarn.
- the combination melt adhesive thread 8 serves for connecting a thread 2 of the thread layer 1 with a thread 4 of the new thread layer 5 (not shown in FIG. 2).
- a yarn supply 14 can be made available to the thread weft nozzle 9 by means of a clamp 10 arranged between the thread weft nozzle 9 and the yarn bobbin 7 and a take-off device 11.
- the clamp 10 can also serve to limit a yarn length shot into the air swirling device 6.
- the yarn 8 of a connection is separated from the bobbin 7 by means of a cutting device 15 arranged in the weft direction after the nozzle 9.
- the air swirling device 6 is provided with an upper and a lower half 16, 17.
- Each of these halves 16, 17 has an essentially semi-cylindrical recess 18, 19. Both the radius and the length of the semi-cylindrical recesses 18, 19 match.
- a partition 20 is arranged in each semi-cylindrical recess 18, 19. In the illustration of the figures, only the partition 20 of the lower half 17 can be seen from the two partition walls.
- the partitions 20 are oriented orthogonally to the longitudinal extent of the semi-cylindrical recesses 18, 19. At their open ends, the recesses 18, 19 taper conically into an essentially circular opening.
- the air swirl device could also be formed in one piece.
- a slot should be made in the longitudinal direction of the tubular air swirling device in the tube wall, which enables threads to be inserted from one side.
- a through hole 55, 56 (Fig. 4, 4a).
- Each of the bores 55, 56 penetrates the wall of the half 17.
- Both bores 55, 56 open approximately tangentially to the boundary surface of the recess 19 which is semicircular in cross section and into the latter.
- the bores 55, 56 serve for the compressed air entry, not shown, with which an air vortex is generated on each side of the partition walls 20.
- Both compressed air vortices move approximately helically from the partition walls towards the respectively open side of the two chambers 23, 24 due to a pressure gradient. Since the two bores 55, 56 open into their respective chambers on different sides with respect to a longitudinal direction of the two chambers 23, 24, the two compressed air vortices have opposite directions of rotation.
- two grooves 25, 26 aligned with one another are made in their wall 20 at an angle of, for example, approximately 0 ° -15 ° with respect to the flat partition wall 20 (FIG. 4).
- the one groove 25 lies on one side of the partition 20 in the one chamber 23, while the other groove 26 comes to rest on the other side of the partition 20 in the other chamber 24.
- the threading nozzle 9 shown in more detail in FIGS. 6 and 7 is connected to the groove 26.
- the thread weft nozzle used can be, for example, those offered by Te Strake Weaving Technology Division, PM Deurne, the Netherlands.
- Such a thread weft nozzle 9 can have a housing 30, in the front end of which an elongated hollow needle body 32 is arranged.
- a nozzle body 31 is located in the housing behind the hollow needle body 32.
- a cone 33 of the nozzle body 31 forms together with a funnel-shaped inlet 34 of the hollow needle body a gap 35. Its size can be changed by axially displacing the nozzle body 31.
- the two halves 16, 17 of the air vortex chamber should be separable from one another for the insertion of the threads to be connected.
- the upper half 16 can be moved into an upper and a lower end position by means of movement, not shown. In the upper end position, the two halves are at a distance from one another, through which two thread ends can be inserted between the two halves without any problems. This enables the two threads to be connected to be inserted axially parallel to the swirl chamber and the halves 16 can then be brought back to their starting position.
- the two chamber halves of each chamber can be slightly offset from one another. In this way it can be avoided that the air flow to be generated hits a longitudinal edge of the two halves when it circulates in the air vortex device.
- the slots 27, 28 necessary for the introduction of the two threads can advantageously be made before the connection is created be closed so that an air vortex can flow in the air vortex device as undisturbed as possible.
- the two halves can lie against one another in the lower end position and one of the halves 16, 17 can be pivoted away or moved perpendicular to the longitudinal axis for the insertion and removal of the threads.
- execution 'approximate form closure elements 28 can in the column 27, are inserted 29th In order to have to provide the closing elements arranged in the chamber walls only on one side, it can be advantageous if the air swirl chamber is slotted only on one side.
- a holding device 45a can be provided, as shown in FIG. 15.
- This has two warp yarn holders 48a, 49a which can be displaced perpendicular to the thread plane.
- the two warp yarn holders 48a, 49a arranged on a line with the slot 27a of the air swirl chamber 23a can thereby grasp the respective threads.
- the threads are then inserted through slot 27a into the air swirl chamber arranged between the two warp yarn holders and held there.
- the warp yarn holders 48a, 49a have to be lowered again.
- the threads follow the movement of the warp yarn holders due to their elastic tension.
- the swirl air can be switched off when moving out of the swirl chamber.
- a holding / swiveling device 45 can also be provided, as used in connection with a heating device 46 according to the invention Purpose will be explained in more detail below, is indicated schematically in Fig. 8.
- the holding / swiveling device 45 has two swiveling levers 48, 49 fastened to a common swiveling axis 47, the free ends 48a, 49a of which are designed as clamping brackets for the two thread ends 50, 51. At least between the two clamping brackets, the two threads lie side by side and against one another with their end regions.
- the holding / swiveling device 45 can also be used to guide the thread ends that are still clamped into the infrared heating device 46 shown in FIG. 8.
- a heating device can have an elliptical reflection wall 52.
- the reflection wall 52 should have a length which corresponds at least to the length of the winding 53 to be produced in each case.
- a rod-shaped IR heating source 54 is arranged in a focal point of the ellipse.
- the clamped thread ends 50, 51 can be pivoted into the other focal point and arranged there for a heating process for a certain dwell time. This is shown in broken lines in FIG. 8.
- the reflection wall 52 can be provided with openings, the shape of which is adapted to the transport path of the thread ends.
- each thread should first be inserted into the two clamp holders and fixed there.
- Those skilled in the art are familiar with handling devices from many areas of textile technology relating to the insertion of tensioned threads, for example, knotting machines.
- There- after the holding / pivoting device 45 pivots the two threads between the two halves 16, 17, whereupon the upper half is lowered into its final working position.
- the threads are arranged between the halves 16, 17 and approximately along their common cylinder axis.
- Compressed air can then be introduced through through bores 55, 56 (FIGS. 4, 4a) opening into each chamber 23, 24 in the region of the dividing wall 20 as well as through the thread weft nozzle 9.
- a combination melt adhesive thread 8 (FIG. 2) is sucked through the thread weft nozzle 9, accelerated in the nozzle and shot into the two grooves 25, 26 (FIGS. 3, 4).
- a first part of the yarn shot into the two grooves is thus located with its front end in the weft direction in one chamber 23, while the remaining part of the yarn 8 is arranged in the other chamber 24.
- the front end of the yarn is then caught by the air vortex in the chamber 23, whereby this end rotates in the vortex around the two thread ends.
- the yarn thereby wraps helically around the two threads 50, 51 in the direction of the open end of the chamber 23. Due to the centrifugal force and the acceleration of the yarn 8 in the direction of the chamber end, the rotating part of the yarn is under one tension. This can lead to the yarn pressing the two thread ends against each other during its winding movement.
- the end of the hot melt adhesive thread 8 used for wrapping can in principle be fixed to the thread ends to be connected in different ways. If hot air is used for the air vortex, the yarn end of the combi melt adhesive thread 8 towards the end of the winding process should already be melted or melted sufficiently to develop an adhesive effect sufficient for fixing. It can also be provided to arrange a small nozzle at the end of the chamber, with which hot air is directed only at the end of the yarn. Finally, in one of other possible embodiments, hot air could also be conducted along the two threads 50, 51. This can bring not only the end of the yarn, but the entire yarn very quickly to the temperature required to produce the adhesive effect.
- the other end of the yarn can already be released during the winding movement of the yarn 8 in one chamber.
- the other half of the yarn is caught by the air vortex of the other chamber 24.
- This air vortex rotates in a direction of rotation opposite to the air vortex of the first chamber 23 and with a longitudinal movement component opposite to this air vortex and running parallel to the threads, helically around the two threads.
- the other end of the yarn is wound around the thread ends in the direction of rotation of the air vortex of this chamber in the second chamber 24.
- This partial winding also begins in the area of the dividing wall 20 and moves helically in the direction of the open end of this second chamber 24.
- an overall winding 53 is formed in which all turns have the same direction of rise, as shown in FIG. 9 is shown.
- the yarn turns at both winding ends can have a smaller pitch than in the region of the center of the winding 53.
- Fig. 10 shows that the different pitches result from the fact that different yarn lengths and possibly different flow velocities of the air swirls are present in the course of the formation of each partial winding. In terms of size and direction, these can lead to different forces acting on the yarn.
- the threads that have already been connected can be guided laterally out of the air vortex (s) by means of the holding / pivoting device 45, without the air vortex having to be switched off for this purpose.
- the upper half 16 is first transferred to its upper end position before the threads 50, 51 wrapped with the yarn are removed.
- the threads can be introduced into the separate infrared heating device 46 shown in FIGS. 8 and 11 with a pivoting movement of the holding / pivoting device 45.
- the threads are arranged therein in a first ellipse focal point 71 and the IR heating source 54 arranged in the other ellipse focal point 69 is switched on.
- Direct IR radiation 70 and IR radiation 72 reflected by the reflection wall 52 onto the ellipse focal point 71 bring about a heat concentration over the entire length of the winding in the region of the thread ends 50, 51, which the combination hot melt adhesive yarn 8 produces in one Sufficient amount of adhesive bond will melt.
- the Hot melt adhesive of the multi-melt adhesive yarn can of course also be melted in another way. In principle, any form of contact and convection heat is suitable, for example also hot air conducted over the winding in the longitudinal direction of the threads 50, 51.
- One or more of the carrier threads 74 which are usually made of polyamide, of the combination hot melt adhesive thread 8 shown in FIGS. 12a and 12b contract due to the action of the heat, which leads to a force fit between the threads and the thread. Without losing the shape of the winding, the melted adhesive penetrates into the threads 50, 51 at least superficially from one or more hot melt adhesive threads 73 of the yarn 8.
- the combined melt adhesive thread 8 connects here to the two thread ends 50, 51. This can also be referred to as a material bond between the thread 8 and the threads 50, 51. This also causes the yarn to be fixed to the threads 50, 51, whereby the solidification of the yarn 8 also increases the tensile strength of the connection.
- the thread ends can already be led out of the heating device 46 when the yarn has been brought to its melting temperature. The solidification process can take place outside the heating device or be completed.
- a multi-melt adhesive thread can be inserted into the shaft 81 and compressed air can be introduced.
- the latter can only be introduced into the duct 81 in FIG. 13 for the sake of clarity.
- the compressed air flowing in the shaft takes the combination melt adhesive yarn with it, as a result of which the yarn in the shaft 81 moves in the direction of the other end of the shaft and thereby winds around the two thread end regions 50, 51.
- This is shown in a highly schematic manner in FIG. 14, the four instantaneous positions 83, 84, 85, 86 of the yarn indicated by the yarn end corresponding to four different snapshots of the same yarn during the winding process.
- a fifth snapshot shows the yarn end in its position 87 with the wrapping completed.
- outlet openings 91 can be provided in a vertebral body 90 in tubes arranged in a star shape relative to one another. Such a device is shown in FIG. 16. The two threads 50, 51 to be connected to one another are guided through the device in the center of the star. The compressed air fed in then flows through all outlet openings 91 in such a way that the outflowing air has a tangential component.
- the resulting air swirls in turn move helically around the thread ends 50, 51.
- a piece of yarn 8 which initially extends transversely to the thread ends, is then entrained by the air swirls and is wound around the thread ends due to the air currents.
- the mechanical winding device 93 shown in FIG. 17 can be provided to produce a winding.
- This can have, for example, a disk-shaped rotary body 94 slotted along a radius line.
- the rotating body 94 can, for example, be rotatably arranged in a bearing part with a rotating hollow shaft, not shown.
- a freely rotatable yarn spool 95 is provided on the rotating body 94, on which a yarn, for example a combination hot melt adhesive yarn 8, is wound.
- the thread ends 50, 51 to be connected are passed both through the slot 96 and through the hollow shaft.
- the rotating body should also be longitudinally movable in the direction of the longitudinal extension of the threads in order to produce the helical winding of the yarn 8.
- the thread end is arranged at the thread ends.
- the rotary body 94 is then set into a translatory movement by drive means, not shown in more detail.
- the yarn 8 is unwound from the bobbin 95 rotating around the thread ends and wound helically around the thread ends with a plurality of turns.
- the tension in the yarn can be adjusted by a bobbin brake, also not shown. After a predetermined length has been wound around the thread ends, the yarn located on the thread ends can be severed by the bobbin.
