Description

Die Erfindung betrifft eine Nahtungsmaschine zum Herstellen einer Stecknaht zum Endlosmachen eines Gewebebandes.The invention relates to a seaming machine for producing a plug seam for making endless of a fabric tape.

Zu den Gewebebändern der eingangs genannten Art gehören insbesondere Entwässerungs- oder Trockensiebe. Gegenüber endlos gewobenen oder durch eine Webnaht endlos gemachten Sieben haben Siebe mit Stecknaht den Vorteil, daß sie in der Entwässerungsmaschine oder im Trockenteil der Papiermaschine selbst durch Zusammenfügen der beiden vorbereiteten Gewebeenden mit einem Steckdraht endlos gemacht werden können. Die Herstellung dieser Stecknähte ist bisher von Hand erfolgt, indem die Kettdrähte einer jeden Gewebeseite zweier zu vernahtender Gewebeenden zurückgewoben oder -zurückgespleißt werden, so daß aufjeder Seite eine Reihe von Kettdrahtschlaufen entsteht, durch die dann der gemeinsame, verbindende Steckdraht geführt werden kann.The fabric tapes of the type mentioned at the beginning include in particular drainage or dryer fabrics. Compared to endlessly woven or made endless by a woven seam Sieves with a seam have the advantage that they are in the dewatering machine or in the dry part of the paper machine itself by joining the two together prepared fabric ends can be made endless with a plug wire. The To date, these plug-in seams have been made by hand using the warp wires of each Woven back or spliced the fabric side of two fabric ends to be sewn so that a row of warp wire loops is created on each side, through which then the common connecting connecting wire can be guided.

Die Herstellung einer solchen Stecknaht von Hand ist ähnlich aufwendig wie in der EP 00 43 441 oder im DE-GM 81 22 451 für das Endlosmachen von Entwässerungssieben mit einer Webnaht beschrieben wird.The production of such a plug seam by hand is similarly complex as in EP 00 43 441 or in DE-GM 81 22 451 for making drainage screens endless a woven seam is described.

Aus der DE-A-2 126 995 ist ein Verfahren zur Herstellung einer Stecknaht zum Endlosmachen eines Gewebebandes, insbesondere eines Siebes, bekannt, bei dem die Kettfadenenden einer jeden Gewebeseite mit einem Hilfskettstreifen verwoben werden und bei dem die Kettfadenenden in einem Spezialwebstuhl aufgereiht, einzeln entsprechend der Webordnung abgetrennt und abwechselnd um einen in der Mitte zwischen den Hilfskettstreifen angeordneten aus wenigstens einem Draht bestehenden Zentraldraht beliebiger Querschnittsfläche herum zurückgeführt und gewoben werden, so daß der Zentraldraht entsprechend dem Arbeitsfortschritt abwechselnd von einem Kettfadenende der rechten und linken Gewebeseite umschlungen wird, während der jeweils gegenüberliegende Kettfaden ohne Umschlingung des Zentraldrahtes zurückgewoben wird, wobei die Kettfadenenden nach dem Eintrag in das der Webordnung entsprechende offene Fach parallel zur Webkante angeschlagen werden. DE-A-2 126 995 describes a method for producing a plug seam for making endless a fabric tape, in particular a sieve, known, in which the warp ends of each side of the fabric are woven with an auxiliary warp strip and the Warp thread ends lined up in a special loom, individually according to the weaving order severed and alternated by one in the middle between the auxiliary warp strips arranged from at least one wire central wire of any cross-sectional area can be returned and woven around so that the central wire according to the progress of work alternating from one end of the right and the left side of the fabric is looped while the opposite warp thread is woven back without wrapping the central wire, the warp ends after the entry in the open compartment corresponding to the weaving regulations parallel to the selvedge be posted.

Nachteilig ist dabei, daß das bekannte Verfahren umständlich zu handhaben ist und deshalb nicht sicher durchführbar ist.The disadvantage here is that the known method is cumbersome to handle and therefore is not feasible.

Der Erfindung liegt die Aufgabe zugrunde, eine Nahtungsmaschine zum Herstellen einer Stecknaht anzugeben, mit der Stecknähte zuverlässig und mit hoher Qualität herstellbar sind.The invention has for its object a seam machine for producing a Specify pin seam with which pin seams can be produced reliably and with high quality are.

Diese Aufgabe wird erfindungsgemäß mit einer Nahtungsmaschine mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This object is achieved with a seam machine with the features of Claim 1 solved. Advantageous further developments are the subject of the subclaims.

Wie aus Fig. 1 ersichtlich, ist die Nahtungsmaschine auf einem Fahrwerk 1 montiert, bestehend aus einem auf Rädern 30 beweglichen Rahmenkörper 31, der sich im Rhythmus des Webfortschrittes über einen gesteuerten Antriebsmotor 2 fortbewegen läßt. Der Rahmenkörper 31 wird unterhalb der Arbeitsebene der Maschine auf beiden Seiten auf zwei parallelen Führungsrohren 3 geführt, die wiederum an ihren Enden an einer waagrechten Traverse 32 eines Ständers 4 befestigt sind. Auf dem Fahrgestell 1 sind auch alle anderen Betriebselemente der erfindungsgemäßen Nahtungsmaschine angebracht, die nicht alle im einzelnen beschrieben werden, da sie zum Verständnis des Arbeitsablaufes bzw. des Verfahrens nicht erforderlich sind.As can be seen from Fig. 1, the seaming machine is mounted on a chassis 1, consisting from a frame body 31 movable on wheels 30, which is in the rhythm of Web progress through a controlled drive motor 2 can move. The frame body 31 is below the working level of the machine on both sides on two parallel guide tubes 3 guided, which in turn at their ends on a horizontal Traverse 32 of a stand 4 are attached. On the chassis 1 are all others Operating elements of the sewing machine according to the invention attached, which are not all in are described individually because they help to understand the workflow or the Procedures are not required.

Die Fachbildungseinrichtung 5 als eines diese Betriebselemente ist über eine Konsole 6 mit dem Fahrgestell verbunden.The shed formation device 5 as one of these operating elements is connected via a console 6 connected to the chassis.

An der Konsole 6 sind die zur Bedienung der Nahtungsmaschine notwendigen Schalt- und Überwachungseinrichtungen angebracht, die nicht dargestellt sind. Darüber hinaus sind an der Konsole 6 bzw. an der Fachbildungseinrichtung 5 für beide Gewebehälften bzw. -seiten Fadentrenner 7, 7' und Übergabegreifer 8, 8' befestigt, wobei die mit dem Strichindex versehenen Bezugszeichen zu der einen Gewebehälfte und die keinen Strichindex aufweisenden Bezugszeichen zu der gegenüberliegenden anderen Gewebehälfte gehören. Unterhalb der Arbeitsebene der Nahtungsmaschine sind die Durchziehgreifer 9, 9' sowie die beiden Webladen 10, 10' gelagert.On the console 6 are the switching and necessary to operate the seaming machine Monitoring devices attached, which are not shown. Beyond are on the console 6 or on the shedding device 5 for both fabric halves or sides Thread separator 7, 7 'and transfer gripper 8, 8' attached, the ones provided with the line index Reference numerals for one half of the fabric and those without a bar index Reference numerals belong to the opposite other tissue half. Below the The working level of the sewing machine are the pull-through grippers 9, 9 'and the two weaving shutters 10, 10 'stored.

In Fig. 1 ist das mit einer Stecknaht zu versehende Siebgewebe 11 unter der Nahtungsmaschine durchgeführt, d. h. die Maschine rollt auf dem mit einer Schutzschicht abgedeckten Sieb. Eine andere Möglichkeit der Führung des Siebgewebes 41 zeigt Fig. 2. Danach wird das Siebgewebe zeltartig über zwei Tragstangen 23, 24 über die Nahtmaschine hinweggeführt.In Fig. 1 is the screen fabric 11 to be provided with a seam under the seaming machine carried out, d. H. the machine rolls on the one covered with a protective layer Sieve. Another possibility of guiding the sieve fabric 41 is shown in FIG. 2. Then the screen fabric is guided over the seaming machine like a tent via two support rods 23, 24.

Die beiden Enden 21, 22 des mit einer Stecknaht zu versehenden Siebgewebes 11 werden vor dem Einlegen in die Nahtungsmaschine soweit vorbereitet, als in einem Bereich von ca. 10 bis 20 cm Breite die Schußfäden entfernt und danach je nach Gewebebindung 10 bis 30 Schußfäden auf den Kettfadenenden 12, 12' in ihrer genauen Webposition zu einem Magazinierbund 13, 13' zusammengefaßt werden. Die Magazinierbunde 13, 13' sind an den endseitigen Ständern 4, 4' des Fahrgestells, von denen in Fig. 1 nur der eine dargestellt ist, mittels einer Klemmvorrichtung 14 befestigt.The two ends 21, 22 of the screen fabric 11 to be provided with a pin seam are Before inserting it into the seaming machine, prepare it as far as in a range of approx. 10 to 20 cm wide, remove the weft threads and then 10 to 30 depending on the weave Weft threads on the warp thread ends 12, 12 'in their exact weaving position to a magazine band 13, 13 'can be summarized. The magazines 13, 13 'are at the ends Stands 4, 4 'of the chassis, of which only one is shown in Fig. 1, by means of a clamping device 14 attached.

Vor Beginn der Nahtung liegt zwischen den beiden ausgefransten Enden des Siebgewebes 11, die von den Magazinierbunden 13, 13' gehalten werden, zu beiden Seiten des Drahtes 16, der als Zentraldraht zu bezeichnen ist, ein Drahtbündel, das aus Orighalschußfäden des Gewebes bestehen kann oder ein aus Originalschußfäden des Gewebes bestehender Streifen 15, 15', auch Hilfskettstreifen genannt, der für den quer zur eigentlichen Siebrichtung verlaufenden Nahtwebprozeß die Kette darstellt. Der Zentraldraht 16 befindet sich genau in der Mitte zwischen beiden Hilfskettstreifen 15, 15'. Die Hilfskettstreifen und der Zentraldraht sind in einer weiteren Spanneinrichtung 17 der Maschine befestigt, die ebenfalls von den Ständern 4, 4' getragen wird.Before the seam begins, lie between the two frayed ends of the mesh 11, which are held by the magazines 13, 13 ', on both sides of the wire 16, which is to be referred to as the central wire, a wire bundle made of original weft threads of the Fabric can be or a strip consisting of original weft threads of the fabric 15, 15 ', also called auxiliary warp strip, for the one running transversely to the actual direction of sieving Seam weaving process represents the chain. The central wire 16 is located exactly in the middle between the two auxiliary warp strips 15, 15 '. The auxiliary warp strips and the Central wires are fastened in a further clamping device 17 of the machine is also carried by the stands 4, 4 '.

Die Einzeldrähte der Hilfskette sowie der Zentraldraht werden in Ösen der Fachbildungseinrichtung 5, die sich oberhalb oder unterhalb der Webebene am Fahrgestell befindet, geführt. Die Abtrennung und Vereinzelung der Kettfadenenden 12, 12' (Fig. 1) mit Hilfe der Fadentrenner 7, 7 erfolgt in an sich bekannter Weise, wobei beiderseitig der Naht gleichartige Nahtbildungselemente wie Fadentrenner 7, 7', Übergabegreifer 8, 8', Durchziehgreifer 9, 9' und Webladen 10, 10' vorgesehen sind. Dabei übernimmt zunächst der Übergabegreifer 8' den vom Fadentrenner 7' vereinzelten Kettfaden und schwingt ihn nach unten in die Übergabeposition der Arbeitsebene, wie aus Fig. 3 ersichtlich. Danach übernimmt der Durchziehgreifer 9 das Kettfadenende und zieht den Kettfaden in das durch die Fachbildungseinrichtung 5 gebildete Vollfach. Daraufhin wird das so eingetragene Kettfadenende durch die Weblade 10' an die Webkante angeschlagen. Nunmehr wird vom innenliegenden Teil des Hilfskettstreifens 15' ein Teilfach gebildet, wie aus Fig. 4 ersichtlich und dasselbe Kettfadenende vom Durchziehgreifer 9 in die genannte Übergabeposition zurückgeschwenkt, wo es der Durchziehgreifer 9' übernimmt, wobei der Übergabegreifer 8' während des Übergabevorgangs Positionierungshilfe durch Andrücken des Kettfadens leistet. Der Durchziehgreifer 9' spannt danach das Kettfadenende an, woraufhin wiederum die Weblade 10' angeschlagen wird. Danach wird das Anschlußteilfach im Hilfskettstreifen 15' gebildet, der nächste Kettfaden vom Übergabegreifer 8' in die Übergabeposition gebracht und vom Durchziehgreifer 9 in das nun aussenliegende Teilfach eingetragen, wie aus Fig. 5 ersichtlich, wonach mit der Weblade 10' wiederum der Kettfaden angeschlagen wird.The individual wires of the auxiliary chain and the central wire are in the eyelets of the specialist training facility 5, which is located above or below the weaving level on the chassis. The separation and separation of the warp ends 12, 12 '(Fig. 1) with the help of Thread separators 7, 7 are carried out in a manner known per se, the seam being the same on both sides Seam formation elements such as thread separators 7, 7 ', transfer grippers 8, 8', pull-through grippers 9, 9 'and weaving shop 10, 10' are provided. The handing gripper takes over first 8 'the warp thread separated by the thread separator 7' and swings it down into the transfer position the working level, as can be seen from FIG. 3. Then the pulling gripper takes over 9 the warp thread end and pulls the warp thread into the through the shedding device 5 full subjects formed. The end of the warp thread entered in this way is then replaced by the Sley 10 'struck on the selvedge. Now the inner part of the Auxiliary warp strip 15 'formed a partial compartment, as shown in Fig. 4 and the same warp thread end swiveled back by the pulling gripper 9 into said transfer position, where it the pull-through gripper 9 'takes over, the transfer gripper 8' during the transfer process Positioning aid by pressing the warp thread. The pulling gripper 9 'then tensions the end of the warp thread, whereupon again the sley 10' is struck. Then the connector compartment is formed in the auxiliary chain strip 15 ', the next warp thread from the transfer hook 8 'brought into the transfer position and from Pull-through gripper 9 entered in the now partial compartment, as in FIG. 5 can be seen, after which the warp thread is in turn struck with the sley 10 '.

Da bei diesen Arbeitsgängen der Zentraldraht 16 am Fachwechsel nicht beteiligt ist, wird er von den Kettdrahtenden auch nicht umschlungen. Dies wird in Fig. 6 durch die Fäden oder Drähte a und b dargestellt Danach wiederholen sich die im obigen beschriebenen Arbeitsgänge in derselben Reihenfolge mit den Folgedrähten oder -fäden c und d, wobei diesmal jedoch der Zentraldraht 16 in den Fachwechsel und damit in die Kettdrahtschlaufe einbezogen wird. Somit bildet nur jeder vierte Kettfaden eines jeden Gewebeendes eine tragende Kettdrahtschlaufe 33, 33', die Längskräfte übertragen kann.Since in these operations the central wire 16 is not involved in the change of subject, it will not embraced by the warp wire ends either. This is shown in Fig. 6 by the threads or Wires a and b shown. Then the operations described above are repeated in the same order with the following wires or threads c and d, this time however, the central wire 16 is included in the change of subject and thus in the warp wire loop becomes. Thus only every fourth warp thread of each fabric end forms a load-bearing one Warp wire loop 33, 33 ', which can transmit longitudinal forces.

Anschließend werden auf dem anderen Hilfskettstreifen 15 die entsprechenden Arbeitsgänge wiederholt, wobei diesmal der Anschlag durch die Weblade 10 erfolgt, und die Drähte oder Fäden e, f sowie g, h eingetragen werden, wie in Fig. 6 dargestellt. Der Aufbau der beiden Webladen 10, 10' ist an sich bekannt und wird daher hier nicht näher erläutert.The corresponding operations are then carried out on the other auxiliary warp strip 15 repeated, this time the stop takes place through the sley 10, and the wires or Threads e, f and g, h are entered, as shown in Fig. 6. The structure of the two Web shop 10, 10 'is known per se and is therefore not explained in more detail here.

Anstelle eines einzigen Zentraldrahtes 16 lassen sich auch mehrere parallel nebeneinanderliegende Steckdrähte einweben, so beispielsweise zwei Steckdrähte 27, 27', wie in Fig. 7 dargestellt, wodurch die Nahtfestigkeit vergrößert wird, weil jeder zweite Kettfaden des Gewebes mitträgt im Gegensatz zu der in Fig. 6 dargestellten Naht. Die Verwendung von zwei Steckdrähten trägt insbesondere der Tatsache Rechnung, daß bei einem häufig benutzten vierschättigen, sogenannten doppellagigen Gewebe die Schlaufen aufgrund der natürlichen Fadenkröpfung abwechselnd lang und kurz ausfallen, wie in Fig. 7 schematisch für ein einfaches Gewebe dargestellt. Die beiden Gewebeenden 15, 15' sind dabei so gegeneinander versetzt angeordnet, daß jeweils eine lange Schlaufe 28 des linken Siebgeweberandes mit einer kurzen Schlaufe 29' des rechten Siebgeweberandes um den rechten Steckdraht 27' und eine kurze Schlaufe 29 des linken Siebgeweberandes mit einer langen Schlaufe 28' des rechten Siebgeweberandes um den linken Steckdraht 27 vereinigt werden.Instead of a single central wire 16, it is also possible to have a plurality of parallel wires lying next to one another Weave plug-in wires, for example two plug-in wires 27, 27 ', as in FIG. 7 shown, which increases the seam strength, because every second warp thread of the In contrast to the seam shown in FIG. 6, the fabric also supports. The use of two plug wires takes into account in particular the fact that one is used frequently four-shaded, so-called double-layered fabric the loops due to the natural Thread offset turns out to be alternately long and short, as shown schematically in FIG simple fabric shown. The two fabric ends 15, 15 'are so against each other staggered, that each have a long loop 28 of the left screen fabric edge a short loop 29 'of the right sieve mesh around the right plug wire 27' and a short loop 29 of the left screen fabric edge with a long loop 28 'of right sieve mesh around the left plug wire 27 are combined.

Um den Vorteil der vollen Nahtfestigkeit auf andere Weise zu erreichen, kann gemäß einer Verfahrensvariante so gearbeitet werden, daß jedes zweite Kettfadenende nach dem Ausfransen der rechten und linken Gewebeseite und ihrer Aufreihung in dem Magazinierbund einzeln jeweils in eine Schlinge 34 einer Drahtspirale 25 eingewoben wird, wobei jedes Kettdrahtende in die Spirale einbindet, wie aus Fig. 8 ersichtlich. Dabei hat es sich als zweckmäßig erwiesen, die mit der eingewobenen Spirale 25 versehenen Siebgewebeenden 15, 15' in einer in Fig. 9 dargestellten Vorrichtung 18 zu führen, die im Fahrgestell 1 der Nahtungsmaschine gelagert ist. Diese Vorrichtung wird insbesondere bei Verwendung von zwei parallelen Drahtspiralen 25, 25' benötigt, von denen jeweils eine einer Siebgewebeseite zugeordnet ist. Diese beiden Drahtspiralen sind nicht miteinander verbunden. Das linke und das rechte Gewebeende werden durch die Vorrichtung 18 mittels Führungsrollen 19, 20 so festgehalten, daß ein seitliches Verrutschen oder Verschieben verhindert wird. Danach werden die Drahtspiralen mit einem gemeinsamen Steckdraht außerhalb der Nahtungsmaschine verbunden. In order to achieve the advantage of full seam strength in another way, according to one Process variant to be worked so that every second warp thread end after fraying the right and left side of the fabric and their alignment in the magazine band is individually woven into a loop 34 of a wire spiral 25, each Includes warp wire end in the spiral, as shown in Fig. 8. It turned out to be Appropriately proven, the screen cloth ends provided with the woven spiral 25 15, 15 'in a device 18 shown in Fig. 9, which in the chassis 1 of the Seaming machine is stored. This device is particularly useful when using two parallel wire spirals 25, 25 'are required, one of which is on the side of a screen fabric assigned. These two wire spirals are not connected to each other. The left and the right tissue end are so by the device 18 by means of guide rollers 19, 20 noted that a lateral sliding or shifting is prevented. After that the wire spirals with a common jumper wire outside the sewing machine connected.

Bei Verwendung eines gemeinsamen Steck- oder Zentraldrahtes ist eine Führungsvorrichtung der in Fig. 9 gezeigten Art nicht erforderlich, da durch den gemeinsamen Zentraldraht eine ausreichende Lagestabilität sichergestellt wird.When using a common plug or central wire is a guide device of the type shown in Fig. 9 is not necessary because of the common central wire sufficient positional stability is ensured.

Die im obigen beschriebene Nahtungsmaschine ist steuerungsmäßig so ausgelegt, daß sie auch in nur eine Gewebeseite eine Drahtspirale 25 der in Fig. 8 gezeigten Art einweben kann. Schließlich ist auch die Möglichkeit gegeben, die Drahtspiralen, die später beim Endlosmachen des Siebes mit einem gemeinsamen Steckdraht verbunden werden, zusammen mit einem in den Spiralen liegenden Draht 26 (Fig. 10) in die Gewebeenden einzuweben.The seaming machine described in the above is designed so that it controls also weave a wire spiral 25 of the type shown in FIG. 8 into only one side of the fabric can. Finally, there is also the possibility of the wire spirals that later make endless of the sieve are connected with a common plug wire weave into the tissue ends with a wire 26 (FIG. 10) lying in the spirals.

Die Nahtungsmaschine ist geeignet, technische Gewebe, wie z.B. Trockensiebe für Entwässerungs-, Papier- und Kartonmaschinen unterschiedlichster Zusammensetzung in Kett- und Schußrichtung (Mono- oder Multifil in Polyester oder Polyamid) und ein- oder mehrlagiger Konstruktion mit Stecknähten auszurüsten. Ebenso können Basisgewebe für Naßfilze in ein- oder mehrlagiger Ausführung mit Stecknähten versehen werden.The sewing machine is suitable for technical fabrics such as Dryer fabrics for drainage, Paper and board machines of various compositions in warp and Weft direction (mono or multifilament in polyester or polyamide) and one or more layers Equip construction with pin seams. Base fabrics for wet felts can also be used single or multi-layer design can be provided with plug seams.

Aus Gründen der Permeabilitätsbeeinflussung kann es in einzelnen Fällen vorteilhaft sein, wenn im Nahtbereich die Hilfsketttäden, also im Originalgewebe die Schußfäden, aus einem anderen Material bestehen als die übrigen Schußfäden im Gewebe.In order to influence permeability, it can be advantageous in individual cases if the auxiliary warp threads in the seam area, i.e. the weft threads in the original fabric, from one different material than the other weft threads in the fabric.
