Description

Anlage zur Herstellung mindestens eines Wirkbandes mit umhä- kelten GummifadenPlant for the production of at least one knitting belt with crocheted rubber thread
Technisches GebietTechnical field
Die Erfindung betrifft eine Anlage zur Herstellung mindestens eines Wirkbandes mit umhäkelten Gummifäden gemäss Oberbegriff des Anspruches 1.The invention relates to a system for producing at least one knitted belt with crocheted rubber threads according to the preamble of claim 1.
Stand der TechnikState of the art
Bei einem normalen gewirkten Band liegen die Gummifäden zuwenig verankert vor und das Gewirk rutscht beim Gebrauch des Bandes um die Gummifäden. Um dies zu verhindern .muss jeweils ein separat umwickelter bzw. umhäkelter Gummifaden verarbeitet werden, was sehr kostenintensiv ist. Heute sind zur Herstellung von Wirkbändern mit rutschfesten Gummifäden folgende Verfahren bekannt.In the case of a normal knitted band, the elastic threads are not sufficiently anchored and the knitted fabric slips around the elastic threads when the band is used. To prevent this, a separately wrapped or crocheted rubber thread must be processed, which is very expensive. Today, the following methods are known for the production of knitted tapes with non-slip rubber threads.
Ein nackter Gummifaden wird auf einer Umhüllmaschine umspon¬ nen. Es handelt sich um ein kostenintensives Verfahren, das auf teueren und lärmigen Maschinen durchgeführt wird. Ein weiteres Verfahren besteht darin, einen nackten Gummifaden mittels einer gesonderten Umhäkelungsmaschine zu umhäkeln. Dieses Verfahren ist zwar etwas günstiger als das Umspinnver¬ fahren, jedoch ist es dennoch hinsichtlich der Verfahrenswei¬ se und der Vorrichtung kostenintensiv. Unter ariderem besteht ein wesentlicher Nachteil des Umhäkelungsverfahrens darin, dass die Maschenzahl pro Längeneinheit des vorumhäkelten Gummifadens mit der entsprechenden Maschenzahl des fertigen Wirkbandes abgestimmt sein sollte, was aufgrund der Elastizi¬ tät des Gummifadens nur schwer zu erreichen ist. Da das Wirkband und der umhäkelte Gummifaden zeitlich und örtlich getrennt hergestellt werden, ergeben sich auch Probleme mit der Farbabstimmung des Umhäkelungsfadens und des Fadens der Kettfransen des Wirkbandes. Die getrennte Herstellung der umhäkelten Gummifäden, ihre Zwischenlagerung, ihre Abstimmung auf die herzustellenden Wirkbänder und das Aufwickeln der umhäkelten Gummifäden auf einem Kettbaum zur Herstellung der Wirkbänder ist sehr kompliziert, kostenintensiv und damit kaum anwendungsgerecht.A bare rubber thread is spun on a wrapping machine. It is a cost-intensive process that is carried out on expensive and noisy machines. Another method is to crochet a bare rubber thread using a separate crochet machine. Although this method is somewhat cheaper than the spinning process, it is nevertheless cost-intensive in terms of the method and the device. Among other things, a major disadvantage of the crochet process is that the number of stitches per unit length of the pre-crocheted Rubber thread should be coordinated with the corresponding number of stitches of the finished knitted band, which is difficult to achieve due to the elasticity of the rubber thread. Since the knitting tape and the crocheted rubber thread are produced separately in terms of time and location, there are also problems with the color matching of the crocheting thread and the thread of the warp fringes of the knitting tape. The separate production of the crocheted rubber threads, their intermediate storage, their coordination with the warp knitting fabrics to be produced and the winding of the crocheted rubber threads on a warp beam for the production of the warp knitting fabrics is very complicated, cost-intensive and therefore hardly suitable for use.
Eine dritte Möglichkeit ist dadurch gegeben, dass Wirkbänder mit nackten Gummifäden hergestellt und gleichzeitig ein Schmelzfaden über die Breite des Bandes eingewirkt wird. Die Nachteile dieses Verfahrens liegen unter anderem im hohen Preis des zusätzlichen Schmelzfadens, der zusätzlichen Schmelzbehandlung und darin, dass zur Führung des Schmelzfa¬ dens eine zusätzliche Schussstange erforderlich ist.A third possibility is that knitting ribbons are made with bare rubber threads and at the same time a melting thread is knitted over the width of the ribbon. The disadvantages of this method include the high price of the additional melt thread, the additional melt treatment and the fact that an additional weft rod is required to guide the melt thread.
Aus der DE-A-43 28 951 ist es auch bekannt, einen Gummifaden direkt im Zuge der Herstellung eines gewirkten Bandes zu ummaschen. Hierzu werden zwei Bindungsfäden verwendet, von denen der eine als stationärer Bindungsfaden stets denselben Gummifaden sowie den vorderen und den hinteren Schussfaden ummascht. Der andere Bindungsfaden ist springend geführt und ummascht nur den auf der einen Seite liegenden Schussfaden und bildet Maschen um einen ersten Gummifaden und um eine geringe, ungerade Anzahl aufeinanderfolgender vorderer und hinterer Schussfäden. Der zweite Bindungsfaden springt dann zu einem benachbarten zweiten Gummifaden und bildet mit diesem eine gleiche Anzahl aufeinanderfolgender vorderer und hinterer Schussfädenmaschen. Das Herstellungsverfahren ist relativ kompliziert und das so hergestellte Band weist eine nur ungegnügende Umhüllung der Giummifäden auf und ist deshalb für hochwertige Produkte ungeeignet sondern nur für einfache Produkte wie Polsterbänder.From DE-A-43 28 951 it is also known to knit a rubber thread directly in the course of producing a knitted band. For this purpose, two binding threads are used, one of which, as a stationary binding thread, always knits around the same rubber thread and the front and the rear weft thread. The other binding thread is jumping and meshes only with the weft thread lying on one side and forms stitches around a first rubber thread and around a small, odd number of successive front and rear weft threads. The second binding thread then jumps to an adjacent second rubber thread and forms an equal number of successive front and rear weft stitches. The manufacturing process is relatively complicated and the tape so produced has one only inadequate wrapping of the gium filaments and is therefore unsuitable for high-quality products but only for simple products such as upholstery tapes.
Aus der DE-A-22 64 297 ist es bekannt, an einer Webmaschine eine Wirkvorrichtung zum Umhüllen anzuordnen. Diese Anlage ist jedoch sehr kompliziert und aufwendig, da zwei grundsätz¬ lich verschiedene Textilmaschinen, d.h. eine Webmaschine und eine Wirkmaschine kombiniert sind, so dass Teile eines Aggre¬ gates nicht für das andere verwendet werden können. Ausserdem ist die Synchronisation der beiden Aggregate schwieirg, was sich nachteilig auf das herzustellende Gewebe auswirkt.From DE-A-22 64 297 it is known to arrange a knitting device for wrapping on a weaving machine. However, this system is very complicated and expensive, since two fundamentally different textile machines, i. a weaving machine and a knitting machine are combined so that parts of one unit cannot be used for the other. In addition, the synchronization of the two units is difficult, which has a disadvantageous effect on the tissue to be produced.
Darstellung der ErfindungPresentation of the invention
Aufgabe der Erfindung ist es, eine Anlage der eingangs ge¬ nannten Art so auszugestalten, dass die erwähnten Nachteile vermieden werden.The object of the invention is to design a system of the type mentioned at the outset in such a way that the disadvantages mentioned are avoided.
Die gestellte Aufgabe wird bei der Anlage der eingangs ge¬ nannten Art durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Dadurch, dass in der Anlage der Bandwirkvorrichtung gleichzeitig eine Umhäkelungsvorrichtung mit Hüllwirknadeln, Hüllfadenlegern und Guiπmifadenlegern zugeordnet ist, wird das Umhäkeln der Gummifädens im gleichen Arbeitsgang synchron mit der Herstellung des Wirkbandes on-line auf der gleichen Anlage durchgeführt. Dadurch werden die Gummifäden zeitge¬ recht in der für das Wirken des Wirkbandes erforderlichen Menge und Aufmachung zur Verfügung gestellt, wobei überdies die Führung der umhäkelten Gummifäden zur Bandwirkvorrichtung sehr exakt erfolgt, so dass sich ein qualitativ hoch stehen¬ des Wirkband auf einfache und kostengünstige Weise herstellen lässt. Da jeweils nur soviel umhäkelter Gummifaden herge¬ stellt wird, wie für den Wirkvorgang erforderlich, wird der umhäkelte Gummifaden stets produktionsgerecht zur Verfügung gestellt und es entsteht praktisch kein Abfall. Das so herge¬ stellte Wirkband weist eine optimale Qualität auf, da es den umhäkelten Gummifaden rutschfest hält und zwar einmal durch die eigene Umhäkelung des Gummifaden und durch die zusätzli¬ chen Verbindungsfransen. Beim Schneiden des hergestellten Wirkbandes springt auch der Gummifaden nicht einwärts, son¬ dern verbleibt im wesentlichen in seiner Lage. Die Anlage ist auch besonders einfach, da für das Umhüllen und Wirken des Bandes gleiche Prinzipien zur Anwendung gelangen, so dass sich die Bauteile und Antriebe auf einfache Weise miteinander kombinieren lassen.The object is achieved in the installation of the type mentioned by the characterizing features of claim 1. The fact that a crochet device with enveloping needles, sheath thread layers and gui thread layers is assigned to the belt knitting device at the same time means that the crocheting of the rubber threads is carried out on-line in synchronism with the production of the knitted belt on the same system. As a result, the rubber threads are made available in the quantity and make-up required for the knitting of the knitting band, and the guiding of the crocheted rubber threads to the band knitting device takes place very precisely, so that the knitting band is of high quality in a simple and inexpensive manner can be made. Since only as much crocheted rubber thread is produced as is necessary for the knitting process, the crocheted rubber thread is always available for production and there is practically no waste. The knitted tape produced in this way has an optimal quality, since it keeps the crocheted rubber thread non-slip, in particular through its own crocheting of the rubber thread and through the additional connecting fringes. When cutting the knitted tape produced, the rubber thread also does not jump inward, but essentially remains in its position. The system is also particularly simple, since the same principles are used for wrapping and working the strip, so that the components and drives can be combined with one another in a simple manner.
Vorteilhafte Ausgestaltungen der Anlage sind in den Ansprü¬ chen 2 bis 11 beschrieben.Advantageous configurations of the system are described in claims 2 to 11.
Grundsätzlich kann die Anlage so ausgebildet sein, dass auf ihr nur ein Wirkband hergestellt wird, vorteilhafter ist jedoch die übliche Ausgestaltung nach Anspruch 2, wonach auf einer Anlage mehrere Bandwirkvorrichtungen vorhanden sind, die eine entsprechende Anzahl von Wirkbändern gleichzeitig herstellen.In principle, the system can be designed such that only one knitting belt is produced on it, but the usual embodiment according to claim 2 is more advantageous, according to which a plurality of belt knitting devices are present on a system, which produce a corresponding number of knitting bands at the same time.
Für die erfindungsgemasse Zuordnung der Umhäkelungsvorrich- tung zur Bandwirkvorrichtung ergeben sich verschiedene Mög¬ lichkeiten. Eine besonders einfache Lösung umschreibt der Anspruch 3, wonach neben der Bandwirkvorrichtung gleichzeitig eine Umhäkelungsvorrichtung zur Herstellung der umhäkelten Gummifäden angeordnet ist, wobei die aus der Umhäkelungsvor¬ richtung austretenden Gummifaden über eine Umlenkvorrichtung der Bandwirkvorrichtung zugeführt wird, so dass mit der Bandwirkvorrichtung entsprechenden Werkzeugen im gleichen Arbeitsgang einerseits die umhäkelten Gummifaden und anderer¬ seits die Wirkbänder hergestellt werden können. Die Herstel¬ lung der umhäkelten Gummifäden und der Wirkbänder erfolgt also synchron, wobei lediglich die Zuführung des umhäkelten Gummifadens zur Bandwirkvorrichtung um die Umlenkstrecke versetzt erfolgt. Durch die Verwendung der gleichen Legestan¬ gen für die Werkzeuge der Umhäkelungsvorrichtung und der Bandwirkvorrichtung ergibt sich nicht nur ein einfacher Aufbau der Vorrichtung sondern insbesondere auch eine exakt synchrone Herstellung der umhäkelten Gummifäden im Verhältnis zur Herstellung des Wirkbandes. Der Gummifadenführer der Umhäkelungsvorrichtung kann an einer separaten Legestange angeordnet sein oder gemäss Anspruch 4 an der gleichen Lege¬ stange wie der Gummifadenführer der Bandwirkvorrichtung, so dass beide Fadenführer exakt die gleichen Bewegungen ausfüh¬ ren.There are various possibilities for assigning the crochet device to the knitting device according to the invention. Claim 3 describes a particularly simple solution, according to which, in addition to the band knitting device, a crochet device for producing the crocheted rubber threads is arranged at the same time, the rubber threads emerging from the crochet device being fed via a deflection device to the band knitting device, so that corresponding tools in the same way with the band knitting device Work step on the one hand the crocheted rubber thread and on the other hand the knitted bands can be produced. The crocheted rubber threads and the knitting bands are therefore produced synchronously, with only the crocheted feed being fed Rubber thread to the belt knitting device offset by the deflection takes place. The use of the same laying bars for the tools of the crochet device and of the knitting device results not only in a simple structure of the device but in particular also in an exactly synchronous production of the crocheted rubber threads in relation to the production of the knitted band. The rubber thread guide of the crochet device can be arranged on a separate laying bar or, according to claim 4, on the same laying bar as the rubber thread guide of the band knitting device, so that both thread guides execute exactly the same movements.
Bezüglich des Abzugs des umhäkelten Gummifadens von der Umhäkelungsvorrichtungkann eine separateAbzugsvorrichtungvorge¬ sehen sein. Besonders vorteilhaft ist jedoch eine Ausgestal¬ tung nach Anspruch 5, wonach für die Bandwirkvorrichtung und die Umhäkelungsvorrichtung die gleiche Abzugsvorrichtung verwendet wird.With regard to the withdrawal of the crocheted rubber thread from the crochet device, a separate take-off device can be provided. However, a configuration according to claim 5 is particularly advantageous, according to which the same take-off device is used for the band knitting device and the crochet device.
Der Anspruch 6 umschreibt eine weitere vorteilhafte Ausfüh¬ rungsformderAnlage, wonachdieUmhäkelungsvorrichtungderBand¬ wirkvorrichtung vorgelagert ist. Beide Vorrichtungen können mit getrennten Antrieben versehen sein, weisen vorzugsweise aber einen gemeinsamen Antrieb auf. Dabei kann der Antrieb so ausgestaltet sein, dass die Umhäkelungsvorrichtung und die Band¬ wirkvorrichtung exakt synchron arbeiten und somit die gleiche Anzahl der Maschen pro cm herstellen. Gegebenenfalls kann jedoch das Übersetzungsverhältnis des Antriebes zur Umhäke¬ lungsvorrichtung geändert werden, so dass die Umhäkelung eine andere Maschenzahl pro cm als das hergestellte Wirkband aufweist. Die Zuführung der umhäkelten Gummifäden zu der Bandwirkvorrichtung kann in direkter Verbindung erfolgen oder vorzugsweise mittels einer Transportvorrichtung gemäss An¬ spruch 7. Dadurch kann die Zuführung des umhäkelten Gummifa- dens zur Bandwirkvorrichtung exakter gesteuert und vorzugs¬ weise die Vorspannung des Gummifadens separat eingestellt werden. Die Umhäkelungsvorrichtung ist vorteilhafterweise gemäss Anspruch 9 über der Bandwirkvorrichtung angeordnet.Claim 6 describes a further advantageous embodiment of the system, according to which the crochet device is arranged upstream of the tape knitting device. Both devices can be provided with separate drives, but preferably have a common drive. The drive can be designed in such a way that the crochet device and the knitting device work exactly synchronously and thus produce the same number of stitches per cm. If necessary, however, the transmission ratio of the drive to the wrapping device can be changed, so that the crocheting has a different number of stitches per cm than the knitted fabric produced. The crocheted rubber threads can be fed to the band knitting device in a direct connection or preferably by means of a transport device according to claim 7. This allows the crocheted rubber threads to be fed to the tape knitting device controlled more precisely and preferably the pretension of the rubber thread can be set separately. The crochet device is advantageously arranged over the knitting device according to claim 9.
Besonders vorteilhaft ist eine Ausgestaltung der Anlage nach Anspruch 10, wonach der Umhäkelungsvorrichtung eine Gummifaden- Zuführvorrichtung mit vorzugsweise einstellbarer Bandspannung zugeordnet ist, so dass dem Gummifaden eine für den Wirkvor¬ gang an der Bandwirkstation geeignete Vorspannung gegeben werden kann.An embodiment of the system according to claim 10 is particularly advantageous, according to which the crochet device is assigned a rubber thread feed device with preferably adjustable belt tension, so that the rubber thread can be given a pretension suitable for the knitting process at the belt knitting station.
Die Kettfäden für die Bandwirkvorrichtung und die Hüllfäden für die Umhäkelungsvorrichtung können mittels separater Fadenzuführvorrichtungen zugeführt werden. Besonders vorteil¬ haft ist jedoch eine Ausgestaltung nach Anspruch 11, wonach die Fäden auf einem gemeinsamen Kettbaum angeordnet sind.The warp threads for the band knitting device and the covering threads for the crochet device can be fed by means of separate thread feeders. However, an embodiment according to claim 11 is particularly advantageous, according to which the threads are arranged on a common warp beam.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Die Figuren 1 und 2 zeigen einen Gummifaden 2, der aus natür¬ lichem oder synthetischem Gummimaterial bestehen kann. Der Gummifaden 2 ist mit einem Umhakelungsfaden 4 umhäkelt. Der Umhakelungsfaden 4 bildet eine Franse, deren Maschen 6 den Gummifaden 2 einschliessen. Der so umhäkelte Gummifaden 2 ist als ganzes mit 8 bezeichnet.Figures 1 and 2 show a rubber thread 2, which may consist of natural or synthetic rubber material. The rubber thread 2 is crocheted with a hooking thread 4. The covering thread 4 forms a fringe, the stitches 6 of which enclose the rubber thread 2. The rubber thread 2 crocheted in this way is designated as a whole by 8.
Die Figur 3 zeigt einen aus umhäkelten Gummifäden 8 der Figuren 1 und 2 hergestelltes Wirkband 10 im Ausschnitt und im Querschnitt. Die umhäkelten Gummifäden 8 sind mittels Schussfäden 12,14 miteinander verbunden, wobei Verbindungs¬ fransen 16 aus Kettfäden 18 die Verbindung zwischen den Schussfäden 12,14 an den einzelnen umhäkelten Gummifäden 8 herstellen.FIG. 3 shows a knitted band 10 made of crocheted rubber threads 8 from FIGS. 1 and 2 in the detail and in cross section. The crocheted rubber threads 8 are connected to one another by means of weft threads 12, 14, connecting fringes 16 made of warp threads 18 producing the connection between the weft threads 12, 14 on the individual crocheted rubber threads 8.
Eine in Figur 4 gezeigte Bandwirkvorrichtung 20 und eine in Figur 5 gezeigte Umhäkelungsvorrichtung bilden jeweils einen Teil einer Anlage zur Herstellung eines Wirkbandes 10 mit eingebundenen umhäkelten Gummifäden 8. Die Bandwirkvorrich¬ tung 20 und die Umhäkelungsvorrichtung 22 sind paarweise seitlich nebeneinander angeordnet. Eine Anlage kann zur Herstellung eines einzigen Wirkbandes 10 ausgebildet sein, wobei dann nur eine Bandwirkvorrichtung 20 und eine Umhäke¬ lungsvorrichtung 22 vorhanden sind, oder zur gleichzeitigen Herstellung mehrerer Wirkbänder, so dass eine entsprechende Anzahl von paarweise angeordneten Bandwirkvorrichtungen 20 und Umhäkelungsvorrichtungen 22 nebeneinander angeordnet sind, wie dies in Figur 6 am Beispiel eines Kettbaumes 24 angedeutet ist, der zur gleichzeitigen Herstellung von fünf Wirkbändern 10,10a,10b,10c,lOd dient. Der Kettbaum 24 stellt den entsprechend paarweise angeordneten Bandwirkvorrichtungen 20 und Umhäkelungsvorrichtungen 22 jeweils Kettfäden 18 zur Herstellung der Verbindungsfransen 16 und Umhakelungsfäden 4 zum Umhäkeln der Gummifäden 2 nach den Figuren 1 bis 3 zur Herstellung der Wirkbänder zur Verfügung.A belt knitting device 20 shown in FIG. 4 and one in FIG FIG. 5 of the crocheting device each form part of a system for producing a knitting tape 10 with integrated crocheted rubber threads 8. The tape knitting device 20 and the crocheting device 22 are arranged side by side in pairs. A system can be designed for the production of a single knitting band 10, in which case only one band knitting device 20 and one wrapping device 22 are present, or for the simultaneous production of several knitting bands, so that a corresponding number of band knitting devices 20 and crocheting devices 22 arranged in pairs are arranged side by side , as indicated in FIG. 6 using the example of a warp beam 24, which is used for the simultaneous production of five knitting bands 10, 10a, 10b, 10c, 10d. The warp beam 24 provides the respective warp knitting devices 20 and crocheting devices 22 arranged in pairs with warp threads 18 for the production of the connecting fringes 16 and crochet threads 4 for the crocheting of the rubber threads 2 according to FIGS. 1 to 3 for the production of the warp knitting bands.
Die in Figur 4 gezeigte Bandwirkvorrichtung 20 ist von übli¬ cher Bauart und enthält einen hin- und hergehenden Balken 26, an dem Wirknadeln 28 befestigt sind, die sich auf einem Abschlagbalken 30 abstützen. Der Abschlagbalken 30 bildet zusammen mit einem Führungsbalken 32 einen Führungsspalt 34 zum Abzug des Wirkbandes 10 mittels einer Abzugsvorrichtung 36. Die Abzugsvorrichtung 36 enthält zwei Walzen 38,40, von denen eine angetrieben ist und über die das' Wirkband 10 abgezogen und zu einer AufWickelvorrichtung 42 geführt wird. Zur Herstellung des Wirkbandes 10 dienen an einer Legestange 44 angeordnete Gummifadenleger 46, die umhäkelte Gummifäden 8 einer Wirkstelle 47 zuführen. Schussfadenleger 48,50 führen die Schussfäden 12,14 ebenfalls der Wirkstelle zu, an der die Fäden mittels der erwähnten Kettfäden 18 eingebunden werden. Hierzu dienen Kettfadenleger 52, die an einer angetriebenen Legestange 54 befestigt sind und die vom Kettbaum 24 kommen¬ den Kettfäden 18 um die Wirknadeln 28 legen, so dass beim Zurückziehen der Wirknadeln entsprechende Maschen am Ab¬ schlagbalken 30 abgeschlagen werden. Zur Überwachung der Kettfäden 18 dienen Kettfadenwächter 56, die zwischen zwei Führungen 58 den Kettfaden abtasten. Die Legestange 44 für die Gummifadenleger 46 und die Legestangen 51 für die Schuss¬ fadenleger 48,50 sind in einem Lagerbock 60 hin- und herge¬ hend geführt, wobei der Lagerbock überdies eine auf- und abgehende Bewegung ausführt. Entsprechende Antriebe sind in grösser Zahl bekannt, so beispielsweise aus der DE-30 34 253 Al oder der CH-661 305, so dass im vorliegenden Rahmen auf diese Antriebe nicht mehr näher eingegangen zu werden braucht.The band knitting device 20 shown in FIG. 4 is of a conventional type and contains a reciprocating bar 26 to which knitting needles 28 are fastened, which are supported on a knock-off bar 30. The knock-off bar 30, together with a guide bar 32, forms a guide gap 34 for pulling off the knitting belt 10 by means of a pull-off device 36 to be led. For the production of the knitting belt 10, rubber thread layers 46 are arranged on a laying bar 44 and feed crocheted rubber threads 8 to a knitting point 47. Weft thread layers 48, 50 also feed the weft threads 12, 14 to the knitting point at which the threads are bound by means of the warp threads 18 mentioned. For this purpose, warp thread layers 52 are used, which are driven Laying bar 54 are fastened and put the warp threads 18 coming from the warp beam 24 around the knitting needles 28, so that when the knitting needles are withdrawn corresponding stitches are knocked off on the knock-off beam 30. To monitor the warp threads 18 are used warp thread monitors 56 which scan the warp thread between two guides 58. The laying bar 44 for the rubber thread layer 46 and the laying bar 51 for the weft thread layer 48, 50 are guided back and forth in a bearing block 60, the bearing block also executing an up and down movement. Corresponding drives are known in large numbers, for example from DE-30 34 253 A1 or CH-661 305, so that in the present context these drives no longer need to be discussed in detail.
Der der Bandwirkvorrichtung 20 zugeführte umhäkelte Gummifa¬ den 8 wird nun in der gleichen Anlage mit der neben der Bandwirkvorrichtung angeordneten Umhäkelungsvorrichtung 22 hergestellt, die in Figur 5 gezeigt ist, so dass gleiche Teile mit gleichen Bezugszeichen versehen sind. Zur Herstel¬ lung des umhäkelten Gummifadens 8 wird ein nackter Gummifaden 2 mittels einer Zuführvorrichtung 61 zugeführt, wobei der Gummifaden 2 aus einem Vorratsbehalter 62 mittels einer ersten Transportvorrichtung 64 aus Rollen 66 entnommen und zu einer zweiten Transportvorrichtung 68 geführt wird, die eben¬ falls aus Rollen 70 gebildet ist. Der Antrieb zwischen den beiden Transportvorrichtungen 64,68 kann so eingestellt werden, dass der nackte Gummifaden 2 mit einer bestimmten Vorspannung zugeführt wird. Der vorgespannte Gummifaden verläuft dann über eine Fadenwächter 72 und eine Umlenkrolle 74 zur Umhäkelungsstelle 76, wobei ein Gummifadenleger 46a den Gummifaden den Hüllwirknadeln 28a zuführt. Der Gummifa¬ denleger 46a ist wiederum an der Legestange 44 angeordnet, die im Lagerbock 60 gelagert ist, wie bereits oben beschrie¬ ben. Zum Umhäkeln dienen bereits anhand der Figuren 1 bis 3 beschriebene Umhakelungsfäden 4, die vom Kettbaum 24 abgezo¬ gen und mittels eines Hüllkettfadenlegers 52a den Wirknadeln 28a zugeführt wird, die dann jeweils die umhüllende Franse an dem nackten Gummifaden 2 bilden. Die umhäkelten Gummifäden 8 werden von der gleichen Abzugsvorrichtung 36 abgezogen, die auch die Wirkbänder 10 aus der Wirkstelle abzieht. Allerdings werden die umhäkelten Gummifäden 8 nicht wie das Wirkband 10 einer AufWickelvorrichtung 42 sondern über eine Umlenkvor¬ richtung 78 mit Umlenkrollen 80 der Wirkstelle 47 der zu¬ geordneten Bandwirkvorrichtung 20 zugeführt, wie aus Figur 4 hervorgeht.The crocheted rubber thread 8 fed to the band knitting device 20 is now produced in the same system with the crocheting device 22 arranged next to the band knitting device, which is shown in FIG. 5, so that the same parts are provided with the same reference numerals. To manufacture the crocheted rubber thread 8, a bare rubber thread 2 is fed by means of a feed device 61, the rubber thread 2 being removed from a storage container 62 by means of a first transport device 64 from rollers 66 and being fed to a second transport device 68, which is also out Rollers 70 is formed. The drive between the two transport devices 64, 68 can be set in such a way that the bare rubber thread 2 is fed with a certain pretension. The pre-tensioned rubber thread then runs via a thread monitor 72 and a deflection roller 74 to the crochet point 76, a rubber thread layer 46a feeding the rubber thread to the enveloping needles 28a. The rubber thread layer 46a is in turn arranged on the laying rod 44, which is mounted in the bearing block 60, as already described above. 1 to 3 are already used for crocheting described hooking threads 4, which are drawn off from the warp beam 24 and fed to the knitting needles 28a by means of a sheath warp thread layer 52a, which then each form the enveloping fringe on the bare rubber thread 2. The crocheted rubber threads 8 are drawn off by the same take-off device 36, which also pulls the knitting bands 10 out of the knitting point. However, the crocheted rubber threads 8 are not fed like the knitting belt 10 to a winding device 42 but via a deflecting device 78 with deflecting rollers 80 to the knitting point 47 of the associated knitting device 20, as can be seen in FIG.
Die Figur 7 zeigt eine weitere Anlage zur Herstellung eines Wirkbandes der in Figur 3 gezeigten Art, wobei diese Anlage eine Bandwirkvorrichtung 20 der in Figur 4 gezeigten Art aufweisen, der eine Umhäkelungsvorrichtung 82 nicht wie in der Anlage der Figuren 4 und 5 nebengeordnet ist sondern vorgeschaltet. Die Umhäkelungsvorrichtung 82 der Figur 7 ist analog der Bandwirkvorrichtung 20 aufgebaut und enthält wiederum an einem Balken 84 angeordnete Hüllwirknadeln 86, die in einem Abschlagbalken 88 hin- und hergehend geführt sind. Dem Abschlagbalken 88 ist ein Führungsbalken 90 vorge¬ lagert, mit dem er einen Führungsspalt 92 zum Abführen des umhäkelten Gummifadens 8 bildet. Der nackte Gummifaden 2 wird wiederum über eine Zuführvorrichtung 94 zugeführt, die analog jener der Figur 5 ausgebildet sein kann. Über Gummifadenleger 96, die an Legestangen 98 angeordnet sind, welche wiederum an einem Lagerbock 100 hin- und hergehend sowie auf- und abge¬ hend geführt sind, wird der Gummifaden 2 der Umhäkelungsstel¬ le 102 zugeführt. Hüllfadenleger 104 sind an einer Legestange 106 angeordnet und legen jeweils den Umhakelungsfaden 4, der in bekannter Weise über entsprechende Fadenwächter 108 zuge¬ führt wird, in die Hüllwirknadeln 86 ein. Zum Antrieb der Bandwirkvorrichtung 20 und der Umhäkelungsvorrichtung 82 dient ein gemeinsamer Antrieb 110 mit einer schematisch angedeuteten Abzweigung 112 für die Bandwirkmaschine 20 und einer ebenfalls schematisch angedeuteten Abzweigung 114 für die Umhäkelungsvorrichtung 82. Dadurch ist ein synchroner Antrieb zwischen der Bandwirkvorrichtung 20 und der Umhäke¬ lungsvorrichtung 22 gesichert. Gegebenenfalls kann in der Abzweigung 114 noch ein nicht näher dargestelltes Regelge¬ triebe angeordnet sein, um die Umhäkelungsvorrichtung 82 mit einer von der Bandwirkvorrichtung 20 abweichenden Antriebsge¬ schwindigkeit zu versehen und dadurch die Anzahl der Maschen pro Längeneinheit gegenüber der Anzahl der Maschen pro Län¬ geneinheit an der Bandwirkvorrichtung 20 zu verändern. Die von der Umhäkelungsvorrichtung 82 hergestellten umhäkelten Gummifäden 8 können entweder der Bandwirkvorrichtung 20 direkt zugeführt werden oder über eine gesonderte Transport¬ vorrichtung 116, die beispielsweise zwei Rollen 118 aufweist, über die die umhäkelten Gummifäden geführt sind. FIG. 7 shows a further system for producing a knitting band of the type shown in FIG. 3, this system having a band knitting device 20 of the type shown in FIG. 4, to which a crochet device 82 is not connected as in the system of FIGS. 4 and 5 but upstream . The crochet device 82 of FIG. 7 is constructed analogously to the tape knitting device 20 and in turn contains enveloping needles 86 arranged on a bar 84, which are guided to and fro in a knock-off bar 88. A guide bar 90 is arranged in front of the knock-off bar 88, with which it forms a guide gap 92 for removing the crocheted rubber thread 8. The bare rubber thread 2 is in turn fed through a feed device 94, which can be designed analogously to that of FIG. The rubber thread 2 is fed to the crochet point 102 via rubber thread layers 96, which are arranged on laying rods 98, which are in turn guided back and forth on a bearing block 100 and up and down. Wrapping thread layers 104 are arranged on a laying bar 106 and in each case insert the wrapping thread 4, which is fed in a known manner via corresponding thread monitors 108, into the enveloping needles 86. A common drive 110 with a schematic is used to drive the belt knitting device 20 and the crochet device 82 indicated branch 112 for the knitting machine 20 and a likewise schematically indicated branch 114 for the crochet device 82. This ensures a synchronous drive between the knitting device 20 and the sheathing device 22. If necessary, a control gear (not shown in more detail) can also be arranged in the branch 114 in order to provide the crochet device 82 with a drive speed which differs from the belt knitting device 20 and thereby the number of stitches per unit length compared to the number of stitches per unit length to change the tape knitting device 20. The crocheted rubber threads 8 produced by the crochet device 82 can either be fed directly to the belt knitting device 20 or via a separate transport device 116 which, for example, has two rollers 118 over which the crocheted rubber threads are guided.
