Definitions

  • the invention relates to a method for supplying the workplaces of finished goods manufacturing machines with at least one set of threads that were previously contained in a loose fabric, namely a fabric that has a low weft density compared to normal fabrics. It is therefore called “loose goods”.

  • the weft loops are woven so that they can later be pulled out again in the form of an uninterrupted weft thread. Then pulling out can be done efficiently and the weft can be used again. The same applies to two opposing weft threads. After pulling out the weft thread or threads, a group of parallel threads remains, which are then fed directly to one or more workstations of finished goods manufacturing machines.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Belieferung der Arbeitsstellen von Fertigwaren-Herstellmaschinen mit mindestens je einer Schar von Fäden, die vorher in einem lockeren Gewebe enthalten waren, nämlich einem Gewebe, das eine gegenüber normalen Geweben geringe Schußdichte hat. Es wird daher « Lockerware » genannt. Die Schußdichte muß immer in Beziehung zu einer aus der Lockerware herzustellenden Fertigware gesehen werden. Ist in einem Extremfall die Fertigware ein Gewebe mit 200 Schußschlaufen je cm, so kann man ein Gewebe mit 20 Schußschlaufen je cm bereits als Lockerware bezeichnen. In den meisten Fällen hat die Lockerware jedoch eine wesentlich geringere Schußdichte. Diese Lockerware enthält Schußschlaufen, die herausziehbar eingetragen sind. Die Schußschlaufen sind so verwebt, daß sie später in Form eines ununterbrochenen Schußfadens wieder herausziehbar sind. Dann läßt sich das Herausziehen rationell bewerkstelligen und der Schußfaden wieder verwenden. Das gleiche gilt für zwei gegenläufig eingetragene Schußfäden. Nach dem Herausziehen des oder der Schußfäden verbleibt eine Schar paralleler Fäden, die dann unmittelbar einer oder mehreren Arbeitsstellen von Fertigwaren-Herstellmaschinen zugeführt werden.The invention relates to a method for supplying the workplaces of finished goods manufacturing machines with at least one set of threads that were previously contained in a loose fabric, namely a fabric that has a low weft density compared to normal fabrics. It is therefore called “loose goods”. The weft density must always be seen in relation to a finished product to be produced from the loose goods. In an extreme case, if the finished product is a fabric with 200 weft loops per cm, a fabric with 20 weft loops per cm can already be described as loose goods. In most cases, the loose goods have a much lower weft density. This loose goods contains weft loops that are pull-out. The weft loops are woven so that they can later be pulled out again in the form of an uninterrupted weft thread. Then pulling out can be done efficiently and the weft can be used again. The same applies to two opposing weft threads. After pulling out the weft thread or threads, a group of parallel threads remains, which are then fed directly to one or more workstations of finished goods manufacturing machines.

Der Begriff « Fäden » soll Monofile, Garne, Zwirne, Bändchen und ähnliches sowie auch elastisches Material einschließen.The term "threads" is intended to include monofilaments, yarns, threads, ribbons and the like, as well as elastic material.

Die Fertigwaren-Herstellmaschinen dienen zur Erzeugung von flächigem Textilgut. Der Begriff « flächiges Textilgut » soll Gewebe und Gewirke einschließen, auch schlauchförmige, sowie Netze. Die Maschinen können insbesondere Webmaschinen, Kettenwirkmaschinen, oder Häkelmaschinen sein, allgemein Maschinen, die mindestens eine Schar paralleler Fäden verarbeiten.The finished goods manufacturing machines are used to produce flat textile goods. The term “flat textile material” is intended to include fabrics and knitted fabrics, including tubular ones, and nets. The machines can be, in particular, weaving machines, warp knitting machines or crochet machines, generally machines that process at least one set of parallel threads.

Es ist bekannt, den Fertigwaren-Herstellmaschinen eine Schar paralleler Fäden unter Verwendung eines Kettbaumes zuzuführen. Die Verwendung von Kettbäumen bringt Nachteile mit sich. Sobald ein Kettbaum leergelaufen ist, muß er gegen einen neuen ausgetauscht werden, und die Kettfäden des neuen Kettbaums müssen mit den vom vorherigen Kettbaum abgelaufenen Fäden verknüpft werden, während die Fertigwaren-Herstellmaschine stillsteht. Der Anknüpfvorgang nimmt verhältnismäßig viel Zeit in Anspruch, was bei schnell arbeitenden Fertigwaren-Herstellmaschinen stark ins Gewicht fällt.It is known to feed a set of parallel threads to the finished goods manufacturing machines using a warp beam. The use of warp beams has disadvantages. As soon as a warp beam is empty, it must be exchanged for a new one, and the warp threads of the new warp beam must be linked to the threads expired from the previous warp beam while the finished goods manufacturing machine is at a standstill. The connection process takes a relatively long time, which is very important for fast-working finished goods manufacturing machines.

Beim Abwickeln der Kettfäden vom Kettbaum ändert sich mit dünner werdendem Wickel der Winkel, unter dem die Kettfäden zu dem folgenden Umlenkorgan, nämlich dem Streichbaum, laufen. Hierdurch ändert sich während des Ablaufs des Kettbaums die Fadenspannung. Oder es ist ein erheblicher mechanischer und/ oder elektronischer Aufwand erforderlich, um die Änderung der Fadenspannung zu kompensieren.When the warp threads are unwound from the warp beam, as the winding becomes thinner, the angle at which the warp threads run to the following deflecting member, namely the match beam, changes. As a result, the thread tension changes during the course of the warp beam. Or a considerable mechanical and / or electronic effort is required to compensate for the change in thread tension.

Kettbäume bedingen Lagerraum und Transportkosten.Warp beams require storage space and transportation costs.

Es ist ferner bekannt, Fertigwaren-Herstellmaschinen eine Schar paralleler Fäden direkt von einem Spulengatter zuzuführen, das heißt von einem Gestell, das eine größere Anzahl von Spulen trägt: Das Spulengatter erfordert viel Raum und erhebliche Investitionskosten. Für jede Spule muß eine Aufsteckstelle vorgesehen sein sowie eine Bremse. Für jeden der von den Spulen ablaufenden Fäden sind verschiedene Umlenkungen erforderlich. Die Spulen selbst bedingen Transport- und Lagerkosten.It is also known to feed a set of parallel threads directly from a creel, that is to say from a frame which carries a larger number of coils: the creel requires a lot of space and considerable investment costs. A plug-on point and a brake must be provided for each coil. Different deflections are required for each of the threads running from the bobbins. The coils themselves involve transportation and storage costs.

Durch die vorliegende Erfindung soll eine Schar paralleler Fäder bereitgestellt werden, ohne daß die Verwendung von Kettbäumen oder von Spulengattern unmittelbar vor einer Fertigwaren-Herstellmaschine erforderlich ist. Diese Aufgabe wird gemäß Anspruch 1 gelöst.The present invention is intended to provide a family of parallel threads without the need to use warp beams or creels immediately before a finished goods manufacturing machine. This object is achieved according to claim 1.

Die Verwendung von Kettbäumen erübrigt sich. Die Lockerware läßt sich sehr einfach dadurch lagern, daß man sie in Speicher, insbesondere Behälter geordnet oder ungeordnet einlaufen läßt. Ein Speicher kann mehrere Tonnen Lockerware aufnehmen und damit die Wickel mehrerer Kettbäume ersetzen. Die Lockerware ist mit geringen Kosten zu transportieren. Man benötigt keinerlei Spulenkerne oder ähnliches, sondern kann zusammenlegbare Behälter, Pappkartons, Gitterboxen oder ähnliche Behälter verwenden, die nur sehr wenig Raum beim Rücktransport einnehmen.The use of warp beams is not necessary. The loose goods can be stored very simply by having them run into storage, in particular containers, in an orderly or unordered manner. A store can hold several tons of loose goods and thus replace the winding of several warp beams. The loose goods can be transported at low cost. You do not need any coil cores or the like, but you can use collapsible containers, cardboard boxes, wire mesh boxes or similar containers that take up very little space during the return transport.

Speicher können in einem Fertigwaren herstellenden Betrieb weit abseits der Fertigwaren-Herstellmaschinen und/oder der Lockerwaren-Herstellmaschinen aufgestellt werden, zum Beispiel in einem besonderen Lagerraum. Die Lockerware kann über größere Entfernungen mit Hilfe von Führungen von einer Lockerwarenwebmaschine in die Speicher befördert und/ oder aus den Speichern zu den Fertigwaren-Herstellmaschinen befördert werden. Man kann aber in einem Fertigwaren-Herstellbetrieb auf die Herstellung von Lockerware verzichten und die Lockerware, insbesonder in zusammenlegbaren Behältern, anliefern lassen.Stores can be set up in a finished goods manufacturing company far away from the finished goods manufacturing machines and / or the loose goods manufacturing machines, for example in a special storage room. The loose goods can be conveyed over longer distances with the aid of guides from a loose weaving machine into the stores and / or from the stores to the finished goods manufacturing machines. But you can do without the production of loose goods in a finished goods manufacturing company and have the loose goods delivered, especially in collapsible containers.

Nach der Erfindung wird die Lockerware zunächst einer-Bremsstelle zugeführt, so daß die Lockerware und die daraus später befreiten Fäden zwischen der Bremsstelle und der Fertigwaren-Herstellmaschine unter Spannung stehen.According to the invention, the loose goods are first fed to a braking point, so that the loose goods and the threads freed therefrom later are under tension between the braking point and the finished goods manufacturing machine.

Aus der gespannten Lockerware werden die Schußschlaufen seitlich herausgezogen. Der oder die Schßfäden werden aufgespult. Anschließend kann die Fadenschar als Ganze einer Arbeitsstelle einer Fertigwaren-Herstellmaschine zugeführt werden. Statt dessen kann die Fadenschar geteilt und mehreren Arbeitsstellen zugeführt werden.The weft loops are pulled out of the tensioned loose goods. The weft thread or threads are wound up. The thread coulter as a whole can then be fed to a work station of a finished goods manufacturing machine. Instead, the thread group can be divided and fed to several jobs.

Nach Anspruch 2 können umgekehrt Fadenscharen aus mehreren Lockerwaren einer einzigen Arbeitsstelle zugeführt werden, insbesondere dann, wenn die herzustellende Fertigware breit ist, zum Beispiel 4000 Kettfäden benötigt, während Lockerware mit nur 500 Kettfäden hergestellt werden soll.Conversely, according to claim 2, sheets of thread from several loose goods can be fed to a single job, in particular then when the finished goods to be produced are wide, for example need 4000 warp threads, while loose goods are to be produced with only 500 warp threads.

Nach Anspruch 3 lassen sich Fertigwaren aus Fäden unterschiedlicher Eigenschaften herstellen, indem man Lockerwaren mit Fäden unterschiedlicher Eigenschaften verwendet. Solche Eigenschaften können eine Färbung, eine Schrumpfung, eine Texturierung und anderes sein.According to claim 3, finished goods can be produced from threads of different properties by using loose goods with threads of different properties. Such properties can be coloring, shrinking, texturing and others.

Wurde die Lockerware mit einer oder zwei aufziehbaren Maschenreihen hergestellt, so ist nach Anspruch 4 auf die Richtung zu achten, in der das Lockerband zum Aufziehen zugeführt wird, denn die Maschenreihen sind nur entgegen ihrer Herstellungsrichtung aufziehbar.If the loose goods were manufactured with one or two rows of loops that can be pulled open, the direction in which the loose tape is fed for drawing up is to be observed according to claim 4, because the rows of stitches can only be pulled up against their direction of manufacture.

Nach dem Leerlaufen eines Kettbaums können die Enden der Kettfäden mit den Anfängen der Kettfäden eines neuen Kettbaumes nur beim Stillstand der Fertigwaren-Herstellmaschine verknüpft werden. Dagegen läßt sich gemäß Anspruch 5 oder 6 Lockerware, die in einem Speicher, zum Beispiel Behälter, lagert, mit Lockerware, die in einem anderen Speicher lagert, verknüpfen, während die Fertigwaren-Herstellmaschine arbeitet. Für den Verknüpfungsvorgang braucht die Maschine also nicht stillgesetzt zu werden. Nach Aufbrauch der in dem einen Speicher lagernden Lockerware wird ohne Unterbrechung die damit verknüpfte Lockerware aus dem nächsten Speicher herausgezogen und der Maschine zugeführt.After a warp beam has run dry, the ends of the warp threads can only be linked to the beginning of the warp threads of a new warp beam when the finished goods production machine is at a standstill. On the other hand, according to claim 5 or 6, loose goods that are stored in one store, for example containers, can be linked to loose goods that are stored in another store while the finished goods manufacturing machine is working. The machine does not need to be shut down for the linking process. After the loose goods stored in one store have been used up, the loose goods associated therewith are pulled out of the next store without interruption and fed to the machine.

Lockerware wird mit einer noch zu beschreibenden Webmaschine gewebt. Die zu verwebenden Kettfäden können im einfachsten Falle von einzelnen Spulen ablaufen, die zum Beispiel auf einem Spulengatter gehaltert sind. Auf diese Weise kann Lockerware in einem Betrieb hergestellt werden, der auch Fertigware erzeugt. Die Lockerware wird geordnet oder ungeordnet in Speicher, insbesondere Behälter gefüllt. Die Behälter können von einem Betrieb, der Lockerware herstellt, an Betriebe geliefert werden, die Fertigware herstellen. Statt dessen kann man in einem Betrieb, der Fertigwaren herstellt, mindestens eine Lockerwarenwebmaschine aufstellen, die von Spulen her Lockerware webt und in dort ortsfest angebrachte größere Speicher füllt. Die Speicher können unter erheblichem Abstand einerseits von der LockerwarenWebmaschine, andererseits von den Fertigwaren-Herstellmaschinen untergebracht sein, und die Lockerware kann zu den Speichern und von diesen zu den Fertigwaren-Herstellmaschinen über Führungen geleitet werden. Werden mehrere Speicher nacheinander gefüllt, so braucht die Lockerware dazwischen nicht unterbrochen zu werden. Führt man aus dem zuletzt gefüllten Speicher das zuletzt fertiggestellte Ende einer Fertigwaren-Herstellmaschine zu, so kann diese die in mehreren Speichern gelagerte Lockerware nacheinander ohne Unterbrechung und ohne Anknüpfvorgänge verarbeiten.Loose goods are woven with a weaving machine to be described. In the simplest case, the warp threads to be woven can run from individual bobbins, which are held on a creel, for example. In this way, loose goods can be produced in a company that also produces finished goods. The loose goods are ordered or disorderly filled in storage, in particular containers. The containers can be supplied by a company that manufactures loose goods to companies that manufacture finished goods. Instead, in a company that manufactures finished goods, you can set up at least one loose goods weaving machine that weaves loose goods from bobbins and fills them into larger stores that are fixed there. The stores can be housed at a considerable distance on the one hand from the loose goods weaving machine, on the other hand from the finished goods manufacturing machines, and the loose goods can be guided to the stores and from these to the finished goods manufacturing machines via guides. If several stores are filled in succession, the loose goods do not need to be interrupted in between. If the last completed end of a finished goods manufacturing machine is fed from the last filled store, it can process the loose goods stored in several stores one after the other without interruption and without connecting processes.

Nach Figur 1 werden in einer Schar 1 von Kettfäden von links her Schußschlaufen 3 eingetragen, und zwar so, daß die geschlossenen Enden 3.1 der Schußschlaufen rechts 1 bis 2 cm überstehen. Bei Verwendung rauher Fäden hat das Lockerband so ausreichend Halt gegen unbeabsichtigtes Aufziehen. Dieses Verfahren eignet sich für Schußdichten mit mindestens 1 Schußschlaufe je cm Warenlänge.FIGS. 1 to 4 show different possibilities for weaving loose tape by methods known per se. According to FIG. 1, weft loops 3 are inserted into a group 1 of warp threads from the left, in such a way that the closed ends 3.1 of the weft loops protrude 1 to 2 cm on the right. When using rough threads, the loose tape has sufficient hold against unintentional unwinding. This method is suitable for weft densities with at least 1 weft loop per cm length of goods.

Nach Figur 2 können Schußschlaufen 3 von links her und gleichzeitig an denselben Stellen Schußschlaufen 5 von rechts her eingetragen werden. Beide Schußschlaufen werden von je einem Eintragorgan in dasselbe Fach eingetragen. Es stehen rechts und links geschlossene Enden 3.1 und 5.1 aus dem Gewebe vor. Diese Webart eignet sich für Lockerware mit geringerer Schußdichte als die nach Figur 1.According to FIG. 2, weft loops 3 can be entered from the left and, at the same time, weft loops 5 from the right. Both weft loops are entered into the same compartment by one entry organ. Closed ends 3.1 and 5.1 protrude from the tissue on the right and left. This weave is suitable for loose goods with a lower weft density than that according to FIG. 1.

Für Schußdichten bis herab zu 1 Schußschlaufe je 10 cm Warenlänge, und eventuell noch geringere Schußdichten eignen sich die Webverfahren nach Figur 3 und 4. Nach Figur 3 wird die Lockerware mit einer Maschenreihe 7 versehen, die aus dem Schußfaden 9 selbst unter Verwendung einer Wirknadel 11 gebildet wird. Zur Erzielung besonders geringer Schußdichten kann das Verfahren beidseitig angewandt werden. Von rechts nach links eingetragene Schußschlaufen können an der linken Seite durch eine zweite Maschenreihe festgelegt werden. Die Maschenreihe ist zusammen mit den Schußschlaufen 3 aufziehbar. Entfernt man die Wirknadel 11 in Figur 3, so kann man die oberste Schußschlaufe 3 nach links herausziehen. Es folgt dann die nächstuntere, wobei die zugehörige Masche ebenfalls aufgezogen wird. Man muß mit dem Aufziehen also an dem zuletzt gewebten Ende beginnen.The weaving methods according to FIGS. 3 and 4 are suitable for weft densities down to 1 weft loop per 10 cm fabric length, and possibly even lower weft densities. According to FIG is formed. The method can be used on both sides to achieve particularly low weft densities. Weft loops entered from right to left can be defined on the left side by a second row of stitches. The row of stitches can be pulled together with the weft loops 3. If the knitting needle 11 in FIG. 3 is removed, the uppermost weft loop 3 can be pulled out to the left. The next lower stitch then follows, the associated stitch also being drawn up. So you have to start winding at the last woven end.

Figur 4 zeigt die Herstellung einer Lockerware unter Verwendung eines Hilfsfadens,13. Hier wird eine Maschenreihe 7' aus den Schußsc#daufen 3 und dem Hilfsfaden gebildet. Zum Aufziehen muß man einerseits den Hilfsfaden 13, andererseits den Schußfaden 2 herausziehen. Unter Verwendung von zwei Schußfäden können von rechts und von links her Schußschlaufen eingetragen werden, und beide können durch je einen Hilfsfaden in je einer Maschenreihe festgelegt werden.FIG. 4 shows the production of loose goods using an auxiliary thread, 13. Here, a row of stitches 7 'from the weft pile 3 and the auxiliary thread. To wind up you have to pull out the auxiliary thread 13 on the one hand and the weft thread 2 on the other hand. Using two weft threads, weft loops can be inserted from the right and from the left, and both can be defined in each course by means of an auxiliary thread.

Figur 5 zeigt eine Vorrichtung, die zwischen einen Speicher für die Lockerware und eine Arbeitsstelle einer Fertigwaren-Herstellmaschine eingeschaltet wird und dazu dient, einerseits die zugeführte Schar 1 aus Kettfäden zu spannen, andererseits dazu, den Schußfaden 2 herauszuziehen. Figur 5 zeigt dies am Beispiel einer Lockerware nach Figur 3, bei der eine Maschenreihe 7 unter Verwendung des Schußfadens 2 gewebt ist.FIG. 5 shows a device which is connected between a store for the loose goods and a work station of a finished goods manufacturing machine and serves on the one hand to tension the supplied sheet 1 from warp threads and on the other hand to pull out the weft thread 2. FIG. 5 shows this using the example of a loose material according to FIG. 3, in which a course 7 is woven using the weft thread 2.

Die Lockerware 17 wird zunächst einer Bremsvorrichtung zugeführt, die bremsbare Walzen 31 und 32, sowie eine Hilfswalze 33 zum Andrücken der Lockerware an die beiden anderen Walzen hat. Die Kettfäden werden von der Arbeitsstelle der Fertigwaren-Herstellmaschine in Richtung des Pfeils 50 gezogen, so daß die Kettfäden zwischen der Arbeitsstelle und der Bremsvorrichtung gespannt gehalten werden.The loose goods 17 are first fed to a braking device which has brakable rollers 31 and 32 and an auxiliary roller 33 for pressing the loose goods onto the other two rollers. The warp threads are pulled from the work station of the finished goods manufacturing machine in the direction of arrow 50, so that the warp threads are kept taut between the work station and the braking device.

Im Anschluß an die Bremsvorrichtung umläuft das Lockerband einen ortsfesten Rundstab 35. Kurz danach wird der Schußfaden 2 nach vorn in Figur 5 herausgezogen, wobei die Maschenreihe 7 aufgezogen wird.Following the braking device, the loose band runs around a stationary round bar 35. Shortly thereafter, the weft thread 2 is pulled out to the front in FIG. 5, the course 7 being drawn up.

Der Schußfaden 2 wird durch einen Fadenführer 55 einer an sich bekannten Fadentransportvorrichtung 57 zugeführt. Diese sorgt für eine bestimmte Abzugsgeschwindigkeit des Schußfadens. Die Abzugsgeschwindigkeit ist passend gewählt zur Länge der herauszuziehenden Schußschlaufen 3 und der von ihnen gebildeten Maschen 58 sowie zur Drehzahl der Walzen 31, 32. Der herausgezogene Schußfaden 2 wird auf eine . Spule 60 gewickelt und kann wieder verwendet werden. Er erhöht also nicht die Materialkosten.The weft thread 2 is fed through a thread guide 55 to a thread transport device 57 known per se. This ensures a certain take-off speed of the weft thread. The take-off speed is selected to match the length of the weft loops 3 to be pulled out and the loops 58 formed by them and the speed of the rollers 31, 32. The weft thread 2 drawn out is wound on a. Coil 60 wound and can be used again. So it does not increase the material costs.

Lockerwaren, die in zwei Behältern 61, 62 lagern, können Kettfaden für Kettfaden miteinander verbunden werden, und zwar während Lockerware aus dem einen Speicher einer Fertigwaren-Herstellmaschine zugeführt wird. Hat die Lockerware eine oder zwei Maschenreihen, so verfährt man wie folgt : Die Lockerwaren werden so eingefüllt, daß außer ihren zuletzt hergestellten Enden 17e, 17e' auch ihre zuerst hergestellten Enden 17a, 17a' von außen zugänglich bleiben. Das zuletzt hergestellte Ende 17e der Lockerware in Speicher 61 wird einer Bremsvorrichtung 30 nach Figur 5 zugeführt. Das zuerst hergestellte Ende 17a dieser Lockerware wird mit dem zuletzt hergestellten Ende 17e' der Lockerware in Speicher 62 verknüpft, und zwar Kettfaden mit Kettfaden und Schußfaden mit Schußfaden und gegebenenfalls Hilfsfaden mit Hilfsfaden. Ist der Speicher 61 entleert, so wird vom Ende 17a das Ende 17e' mitgenommen, so daß anschließend der Speicher 62 entleert wird. Die Kettfäden dieser Lockerware durchlaufen mit ihren Anknüpfstellen 63 die Fertigwaren-Herstellmaschine. Falls erforderlich kann später ein Stück Fertigware mit den Anknüpfstellen herausgeschnitten werden.Loose goods, which are stored in two containers 61, 62, can be connected to one another warp thread by warp thread, while loose goods are fed from one store to a finished goods production machine. If the loose goods have one or two rows of stitches, the procedure is as follows: The loose goods are filled in such a way that, in addition to their last ends 17e, 17e ', their first ends 17a, 17a' remain accessible from the outside. The last manufactured end 17e of the loose goods in memory 61 is fed to a braking device 30 according to FIG. The end 17a of this loose material produced first is linked to the last manufactured end 17e 'of the loose material in memory 62, namely warp thread with warp thread and weft thread with weft thread and optionally auxiliary thread with auxiliary thread. If the memory 61 is emptied, the end 17e 'is carried along from the end 17a, so that the memory 62 is subsequently emptied. The warp threads of these loose goods pass through the finished goods manufacturing machine with their connecting points 63. If necessary, a piece of finished goods can later be cut out with the attachment points.

Entleerte Speicher werden entweder durch gefüllte ersetzt oder an Ort und Stelle belassen und von einer Lockerwarenwebmaschine wieder gefüllt.Emptied stores are either replaced by filled ones or left in place and refilled by a loose goods weaving machine.

Figur 7 bis 9 zeigen verschiedene Möglichkeiten, Lockerware den Arbeitsstellen 64 von Fertigwaren-Herstellmaschinen zuzuführen.FIGS. 7 to 9 show different possibilities for feeding loose goods to the work stations 64 of finished goods manufacturing machines.

Nach Figur 7 wird abwechselnd aus Speichern 61, 62 oder aus mehr als zwei Speichern Lockerware 17 durch eine Aufziehvorrichtung 27 einer Arbeitsstelle 64 zugeführt.According to FIG. 7, loose goods 17 are fed alternately from stores 61, 62 or from more than two stores through a pull-up device 27 to a work station 64.

Die der Aufziehvorrichtung 27 immer vorgeschaltete Bremsvorrichtung 30 wurde in Figur 7 bis 9 nicht dargestellt.The braking device 30, which is always connected upstream of the winding device 27, was not shown in FIGS. 7 to 9.

Nach Figur 8 wird Fertigware 17 aus einem von zwei Speichern 61, 62 wiederum einer Aufziehvorrichtung 27 zugeführt. Die diese verlassende Fadenschar wird in drei Scharen 1a, 1b und 1c unterteilt. Jede dieser Teilfadenscharen wird einer Arbeitsstelle 64a, 64b und 64c zugeführt.According to FIG. 8, finished goods 17 are in turn fed from one of two stores 61, 62 to a winding device 27. The thread group leaving this is divided into three groups 1a, 1b and 1c. Each of these thread sets is fed to a work station 64a, 64b and 64c.

Nach Figur 9 wird Lockerware unterschiedlicher Eigenschaften verarbeitet. Speicher 61, 62 enthalten Lockerware 17a einer bestimmten Eigenschaft, Speicher 65, 66 Lockerware 17b einer anderen Eigenschaft. Die Eigenschaften können unterschiedliche Färbung sein, unterschiedliche Bruchdehnungszahlen, das heißt insbesondere unterschiedliche Schrumpfungen der Kettfäden und anderes. Die Lockerware 17a läuft in eine Aufziehvorrichtung 27a ein, die Lockerware 17b in eine Aufziehvorrichtung 27b. Die von dieser befreite Fadenschar 1b läuft in ganzer Breite in eine Arbeitsstelle 64 ein. Die die Aufziehvorrichtung 27a verlassende Fadenschar wird in zwei Scharen 1a1 und 1a2 unterteilt. Die beiden Teilscharen bilden die Randkettfäden des in der Arbeitsstelle 64 hergestellten Gewebes oder Gewirkes oder dergleichen. Die letztgenannte Anordnung hat Bedeutung für die Herstellung von Kraftfahrzeugsicherheitsgurten mit Schlauchkanten, wobei die Kantenkettfäden stärker geschrumpft sind als die Kettfäden des Mittelteils.According to FIG. 9, loose goods with different properties are processed. Stores 61, 62 contain loose goods 17a of a certain property, stores 65, 66 loose goods 17b of another property. The properties can be different coloring, different elongation at break values, that means in particular different shrinkage of the warp threads and others. The loose goods 17a run into a pull-up device 27a, the loose goods 17b into a pull-up device 27b. The thread sheet 1b freed from this runs into a work station 64 over its entire width. The group of threads leaving the winding device 27a is divided into two groups 1a1 and 1a2. The two coulters form the edge warp threads of the woven or knitted fabric or the like produced in the work station 64. The latter arrangement is important for the production of motor vehicle seat belts with hose edges, the edge warp threads having shrunk more than the warp threads of the middle part.

Analog können einer Arbeitsstelle 64 nebeneinander mehrere Fadenscharen zugeführt werden, die aus verschiedenen Lockerwaren stammen, so kann zum Beispiel eine Ware hergestellt werden, die in Längsrichtung mehrere Farbstreifen hat.Analogously, a plurality of thread groups that come from different loose goods can be fed to a work station 64 side by side, for example a product can be produced that has several color strips in the longitudinal direction.

Figur 10 bis 13 zeigen die Herstellung einer relativ schmalen Lockerware auf einer Nadelbandwebmaschine. Von einer Fadenbearbeitungsmaschine oder einem Spulengatter wird eine Schar 1 von Kettfäden der Nadelbandwebmaschine zugeführt. Sie hat unter anderem eine Schußfaden-Eintragnadel 70, eine Wirknadel 11 und ein Riet oder Webblatt 74. Die Wirknadel ist in Band-Längsrichtung zwischen ihren beiden Endstellungen verschiebbar, die in Figur 10 und 11 dargestellt sind. Maschinenfest und lotrecht zur Bandebene ist ein Umlenkstab 76 in Form eines Keramikzylinders dicht neben der Wirknadelbahn angebracht, und zwar dicht hinter der Anschlagstelle 77 des Riets 74 (Fig. 11).FIGS. 10 to 13 show the production of a relatively narrow loose material on a needle ribbon weaving machine. A set 1 of warp threads is fed to the needle ribbon weaving machine from a thread processing machine or a creel. It has, inter alia, a weft insertion needle 70, a knitting needle 11 and a reed or reed 74. The knitting needle can be displaced in the longitudinal direction of the ribbon between its two end positions, which are shown in FIGS. 10 and 11. A deflecting rod 76 in the form of a ceramic cylinder close to the knitting wire is machine-fixed and perpendicular to the band plane delbahn attached, just behind the stop 77 of the reed 74 (Fig. 11).

Auf der der Wirknadel gegenüberliegenden Seite der Warenbahn ist ein winkelförmiger Schußfadenrückhalter 78 (Fig. 13) um eine waagerechte Achse 80 schwenkbar angeordnet. Ein derartiger Fadenrückhalter wird auch als Fadenstecher (englisch : stitcher, französisch: piqueur) bezeichnet. Figur 13 zeigt seine beiden Extremstellungen. Er hat unterhalb seines kugelförmigen Endes 82 eine Einschnürung 83 zur sichereren Führung des Schußfadens 2.On the side of the fabric web opposite the knitting needle, an angular weft retainer 78 (FIG. 13) is arranged to be pivotable about a horizontal axis 80. Such a thread retainer is also referred to as a thread cutter (English: stitcher, French: piqueur). Figure 13 shows its two extreme positions. It has a constriction 83 below its spherical end 82 for more secure guidance of the weft thread 2.

Wirkungsweise :

  • In der Stellung nach Figur 10 läuft der vom Gewebe herkommende Schußfaden 2.1 um die Einschnürung des Schußfadenrückhalters 78, der seine obere Lage einnimmt. Die Schußfaden-Eintragnadel 70 hat eine Schlaufe 3 des Schußfadens nach rechts eingetragen, und der Kopf 11.1 der Wirknadel 11 hat gerade das Stück 2.2 des Schußfadens ergriffen und beginnt sich in Abzugsrichtung (Pfeile 85, 86) zu bewegen. Auf dem Schaft der Wirknadel 11 befindet sich von der vorangehenden Maschenbildung noch eine Schußschlaufe 3.2. Während die gewebte Lockerware 17 abgezogen wird, bewegt sich die Wirknadel in ihre Endstellung nach Figur 11, wobei aus der vorher gebildeten Schlaufe 3.2 eine Masche gebildet und abgeschlagen wird. Es wird eine neue Schlaufe 3.3 gebildet, die eine Verlängerung der Schußschlaufe 3 ist. Die Schlaufe 3.3 wird vom Kopf 11.1 der Wirknadel um den Umlenkstab 76 herum in Abzugsrichtung (Pfeil 85) gezogen. Der Schußfadenrückhalter 78 hat sich abwärts bewegt und den Schußfaden 2.1 freigegeben, so daß nun im Gewebe vorübergehend eine lockere Schlaufe 92 liegt. Nach Rietanschlag und Fachumstellung wiederholt sich der Vorgang, wobei durch den schnellen Warenabzug die Schlaufe 92 straffgezogen wird.
Mode of action:
  • In the position according to FIG. 10, the weft 2.1 coming from the fabric runs around the constriction of the weft retainer 78, which occupies its upper position. The weft insertion needle 70 has entered a loop 3 of the weft to the right, and the head 11.1 of the knitting needle 11 has just gripped the piece 2.2 of the weft and begins to move in the direction of withdrawal (arrows 85, 86). On the shaft of the knitting needle 11 there is still a weft loop 3.2 from the previous stitch formation. 11, the knitting needle moves into its end position according to FIG. 11, a loop being formed and knocked off from the loop 3.2 previously formed. A new loop 3.3 is formed, which is an extension of the weft loop 3. The loop 3.3 is pulled by the head 11.1 of the knitting needle around the deflecting rod 76 in the pull-off direction (arrow 85). The weft retainer 78 has moved downward and released the weft 2.1, so that a loose loop 92 is now temporarily in the fabric. After the Rietanschlag and change of subject, the process is repeated, the loop 92 being pulled taut by the rapid removal of goods.

Lockerware größerer Breite wird ebenfalls unter Eintragung von Schußschlaufen hergestellt. Hierzu dienen dann jedoch anstelle der in Figur 10 und 11 dargestellten Eintragnadel 70 andere bekannte Organe.Loose goods of greater width are also produced with the entry of weft loops. For this purpose, however, other known organs serve instead of the insertion needle 70 shown in FIGS. 10 and 11.
