Description

Verfahren und Nadelbandwebmaschine zum Weben eines BandesMethod and needle loom for weaving a tape
Technisches GebietTechnical area
Die Erfindung betrifft ein Verfahren zum Weben eines Bandes auf einer Nadel- bandwebmaschine gemäss Oberbegriff des Anspruches 1, sowie eine Nadelbandwebmaschine zur Durchführung des Verfahrens gemäss Oberbegriff des Anspruches 5.The invention relates to a method for weaving a tape on a needle ribbon loom according to the preamble of claim 1, as well as a needle loom for carrying out the method according to the preamble of claim 5.
Stand der Technik Eine Verfahren und eine Nadelbandwebmaschine zum Weben eines Bandes der eingangs genannten Art sind aus der DE 40 09 455A bekannt. Das dort beschriebene Verfahren zur Herstellung eines Bandes auf einer Nadelbandwebmaschine erfolgt mit zwei gegenläufig arbeitenden geschlossenen Schussnadeln, wobei das Band von beiden Schussnadeln durch Eintrag in ein gemein- sames Fach gewoben wird. Die Köpfe der gegenläufig eingetragenen Schussfadenschlaufen werden an jeder Bandseite durch aus je einem Hilfsfaden gebildete Maschenreihen gesichert, die sich an den beiden Kanten des Bandes befinden. Nachteilig ist es nun, dass stets zwei Schussfadenschlaufen in ein gemeinsames Fach eingetragen werden müssen, sodass bei einem Fachwech- sei zwei Schussfadenschlaufen, das heisst vier Schussfadenabschnitte gleichzeitig eingebunden werden müssen. Dadurch wird die Stabilität des herzustellenden Bandes beeinträchtigt. Es sind auch keinerlei Variationen möglich, denn es kommen geschlossene Schussnadeln zum Einsatz, die FührungsSchlaufen aufweisen, an denen stets ein Schussfaden angeordnet ist.PRIOR ART A method and a needle ribbon weaving machine for weaving a ribbon of the type mentioned in the introduction are known from DE 40 09 455A. The method described there for producing a band on a needle loom is carried out with two counter-rotating closed weft needles, wherein the band is woven by both weft needles by entry into a common compartment. The heads of the counter-registered weft loops are secured on each side of the belt by each formed from a thread stitch courses, which are located at the two edges of the belt. The disadvantage now is that always two weft loops must be entered into a common compartment, so that in a Fachwech- be two weft loops, that is, four weft sections must be involved simultaneously. This affects the stability of the tape to be produced. There are also no variations possible, because there are closed weft needles used, the guide loops on which a weft thread is always arranged.
Darstellung der ErfindungPresentation of the invention
Aufgabe der Erfindung ist es, das Verfahren zum Weben eines Bandes auf einer Nadelbandmaschine mit zwei gleichzeitig und gegenläufig arbeitenden Schussnadeln zu verbessern.The object of the invention is to improve the method for weaving a tape on a needle belt machine with two simultaneously and counter-rotating weft needles.
Gelöst wird die Aufgabe: a. bei dem eingangs genannten Verfahren durch die kennzeichnenden Merkmale des Anspruches 1; - -The problem is solved: a. in the method mentioned by the characterizing features of claim 1; - -
b. bei der eingangs genannten Nadelbandwebmaschine durch die kennzeichnenden Merkmale des Anspruches 5.b. in the case of the above-mentioned needle ribbon loom by the characterizing features of claim 5.
Dadurch, dass nur derjenige Schuss eingetragen wird, der einer der beiden Schussnadeln vorgelegt wird, ist jede beliebige Schussfolge möglich. Es können nicht nur zwei Schussfaden gleichzeitig in das Webfach eingebracht werden, wie dies beim Stand der Technik gegeben ist, sondern es können insbesondere nach Anspruch 2 die Schussfäden von den Bandseiten zu Bandseiten wechselnd eingetragen werden, sodass bei jedem Fachwechsel nur eine Schussfadenschlaufe eingetragen wird. Darüber hinaus ist es überdies möglich, den Schussnadeln sogar hinsichtlich Farbe und Qualität wechselnde Schussfäden vorzulegen. Dadurch ergibt sich nicht nur eine mechanisch verbesserte Qualität des hergestellten Bandes, sondern es wird auch die Mustermöglichkeit erhöht.The fact that only one shot is entered, which is submitted to one of the two weft needles, any shot sequence is possible. Not only can two weft threads be introduced into the shed at the same time, as is the case in the prior art, but in particular according to claim 2, the weft threads can be alternately inserted from the sides of the strip to sides of the strip so that only one weft thread loop is inserted at each change of shed. Moreover, it is also possible to present the weft needles even in terms of color and quality changing wefts. This not only results in a mechanically improved quality of the produced strip, but it is also the pattern possibility increased.
Gemäss Anspruch 3 können an jeder Bandseite die Schussfadenschlaufen mit sich selbst verwirkt werden oder gemäss Anspruch 4 mittels eines vermasch- ten Hilfsfadens.According to claim 3, the weft loops can be forfeited with themselves on each side of the band or according to claim 4 by means of a meshed auxiliary thread.
Für die zur Durchführung des Verfahrens dienende Nadelbandwebmaschine ist es wesentlich, dass an jeder Bandseite ein individuell arbeitender Fadenheber zum Vorlegen eines Schussfadens an eine offen ausgebildete Schussnadel vorhanden ist.For the Nadelbandwebmaschine serving to carry out the method, it is essential that an individually operating thread lifter for presenting a weft thread to an open trained weft needle is present on each side of the tape.
Der Anspruch 6 beschreibt eine bevorzugte Ausbildung der Schussnadel, die eine an einem Nadelschaft angeordnete Gabel zur Aufnahme des Schussfadens aufweist, sowie einen längs des Nadelschaftes bis vor die Gabel verlaufenden Führungsschlitz für den Schussfaden aufweist.The claim 6 describes a preferred embodiment of the weft needle having a arranged on a needle shank fork for receiving the weft yarn, and has a along the needle shank extending to the fork guide slot for the weft.

Wege zur Ausführung der ErfindungWays to carry out the invention
Die Figuren 1 bis 4 zeigen den Webbereich einer Nadelbandwebmaschine mit zwei gegenläufig angetriebenen Schussnadeln 2a, 2b, die Schussfäden 4a,4b in ein Webfach 6 eintragen. In dem aus Kettfäden 8 gebildeten Webfach 6 werden die Schussfäden an der Anschlagkante 10 mittels eines Webblattes 9 angeschlagen, worauf das Band 12 entsteht.Figures 1 to 4 show the weaving area of a needle loom with two counter-driven weft needles 2a, 2b, the weft threads 4a, 4b enter into a shed 6. In the shed 6 formed from warp threads 8, the weft threads are struck at the stop edge 10 by means of a reed 9, whereupon the tape 12 is formed.
Die Schussnadeln 2a, 2b sind jeweils offene Nadeln, d.h. sie weisen am vorde- ren Ende eines Nadelschafts 14a, 14b eine Gabel 16a, 16b auf, in die der jeweilige Schussfaden 4a, 4b mittels eines auf- und abbewegbaren Fadenhebers 18a, 18b eingelegt wird. Die Schussnadeln 2a, 2b enthalten jeweils Führungsschlitze 20a, 20b, die längs des Nadelschaftes 14a, 14b verlaufen und bis über - -The weft needles 2a, 2b are in each case open needles, ie they have at the front end of a needle shaft 14a, 14b a fork 16a, 16b into which the respective weft thread 4a, 4b is inserted by means of a thread lifter 18a, 18b movable up and down , The weft needles 2a, 2b each contain guide slots 20a, 20b which extend along the needle shank 14a, 14b and over - -
die Gabeln 16a, 16b reichen. Die Führungsschlitze 20a, 20b dienen zur Führung des Schussfadens 4a, 4b, wenn der Schussfaden nicht in das Webfach 6 eingetragen wird, und zur Erleichterung des Einlegens in die Gabel 16a, 16b mit Hilfe des jeweiligen Fadenhebers 18a, 18b. Die jeweils eingetragene Schussfadenschlaufe 22a, 22b wird mittels eines Hilfsfadens 24a, 24b gesichert, der jeweils mittels eines Fadenführers 26a, 26b Wirknadeln 28a, 28b so vorgelegt wird, dass dieser mit den Schussfadenschlaufen 22a, 22b vermascht wird.the forks 16a, 16b are enough. The guide slots 20a, 20b serve to guide the weft thread 4a, 4b when the weft thread is not entered into the shed 6, and to facilitate insertion into the fork 16a, 16b by means of the respective thread lifter 18a, 18b. The respective inserted weft thread loop 22a, 22b is secured by means of an auxiliary thread 24a, 24b, which is presented by means of a thread guide 26a, 26b knitting needles 28a, 28b so that it is meshed with the weft thread loops 22a, 22b.
In der in Figur 1 gezeigten Stellung hat die linke Schussnadel 2a gerade eine Schussfadenschlaufe 22a in das Webfach 6 eingetragen und ist mittels des Webblattes 11 an der Anschlagkante 10 angeschlagen worden. Mittels des linken Fadenhebers 18a wird der linke Schussfaden 4a an der Gabel 16a der Schussnadel 2a durch Anheben des Fadenhebers 18a soweit angehoben, dass er nicht von der Gabel 16a der Schussnadel 2a erfasst werden kann. Auf der rechten Seite des Webfaches senkt sich der Fadenheber 18b ab und bringt den Schussfaden 4b an der Gabel 16b der Schussnadel 2b in Eingriff, so dass diese die Schussfadenschlaufe 22b in das offene Webfach 6 eintragen kann, wie dies in Figur 2 gezeigt ist. Die linke Schussnadel 2a läuft leer in das Webfach ein, wobei der Schussfaden 4a im Führungsschlitz 20a geführt ist.In the position shown in Figure 1, the left weft needle 2a has just entered a weft loop 22a in the shed 6 and has been struck by means of the reed 11 at the stop edge 10. By means of the left thread lifter 18a, the left weft thread 4a on the fork 16a of the weft needle 2a is raised by lifting the thread lifter 18a so far that it can not be caught by the fork 16a of the weft needle 2a. On the right side of the shed, the thread lifter 18b lowers and engages the weft thread 4b on the fork 16b of the weft needle 2b so that it can enter the weft thread loop 22b into the open shed 6, as shown in FIG. The left weft needle 2a runs empty into the shed, the weft thread 4a being guided in the guide slot 20a.
Wenn die Schussfadenschlaufe 22b vollständig in das Webfach eingetragen worden ist, wie dies aus Figur 3 ersichtlich ist, erfasst die linke Wirknadel 28a den Hilfsfaden 24a und zieht diesen durch die eingetragene Schussfaden- schlaufe 22b und weiter durch die letzte Schlaufe 30a des Hilfsfadens 24a. Auf der rechten Seite wird der Hilfsfaden 24b mit sich selbst, das heisst mit seiner letzten Schlaufe 30b vermascht, ohne durch eine Schussfadenschlaufe gezogen zu sein. Nach diesem Sichern der eingetragenen Schussfadenschlaufe 22b mittels des Hilfsfadens 24a verlassen die Schussnadeln 2a, 2b das Webfach und das Webblatt 11 schlägt die so eingetragene Schussfadenschlaufe an der Anschlagkante 10 an. Nun wird der Fadenheber 18b wieder angehoben und verhindert ein Eingreifen des Schussfadens 4b an der Gabel 16b de.r Schussnadel 2b. Stattdessen wird mittels des Fadenhebers 18a der Schussfaden 4a an der Gabel 16a der Schussnadel 2a in Eingriff gebracht, um bei der nächsten Webfachöffnung eine weitere Schussfadenschlaufe 22a in analoger Weise von der linken Bandseite einzutragen.When the weft loop 22b has been completely inserted into the shed, as can be seen in FIG. 3, the left knitting needle 28a grasps the auxiliary thread 24a and pulls it through the inserted weft thread loop 22b and on through the last loop 30a of the auxiliary thread 24a. On the right side, the auxiliary thread 24b is interlaced with itself, that is to say with its last loop 30b, without being pulled through a weft thread loop. After this securing the registered weft thread loop 22b by means of the auxiliary thread 24a, the weft needles 2a, 2b leave the shed and the reed 11 strikes the weft loop so entered at the stop edge 10. Now the thread lifter 18b is raised again and prevents engagement of the weft thread 4b on the fork 16b de.r weft needle 2b. Instead, by means of the thread lifter 18a of the weft thread 4a at the fork 16a of the weft needle 2a engaged to enter at the next shed opening another weft loop 22a in an analogous manner from the left hinge side.
Die Figuren 5 bis 7 zeigen eine Nadelbandwebmaschine, die analog der Nadelbandwebmaschine der Figuren 1 bis 4 aufgebaut ist, sodass mit dem ersten Ausführungsbeispiel gleiche Teile mit gleichen Bezugszeichen versehen sind. Es wird auf die diesbezüglichen Ausführungen in den Figuren 1 bis 4 verwiesen. Beim Ausführungsbeispiel der Figuren 5 bis 7 kommen jedoch keine Hilfs- fäden zum Einsatz, sondern die Schussfäden 40a, 40b werden mit sich selbst vermascht. Die Figur 6 zeigt, wie mittels der linken Schussnadel 2a die Schussfadenschlaufe 42a aus dem Schussfaden 40a in das Webfach eintragen wird. Nach dem vollständigen Eintrag erfasst die rechte Wirknadel 28b die eingetragene Schussfadenschlaufe 42a und zieht diese durch die bereits abge- schlagene Schussfadenschlaufe 42a. Während des Eintragens der Schussfadenschlaufe 42a mittels der Schussnadel 2a von der linken Seite des Bandes her bewegt sich die rechte Schussnadel 2b leer durch das Kettfach. Der Schussfaden 40b ist dabei im Führungsschlitz 20b der rechten Schussnadel 2b geführt, wie der Figur 7 zu entnehmen ist. Sobald die Schussnadeln 2a, 2b aus dem Kettfach zurückgezogen sind, erfolgt der Anschlag der eingetragenen Schussfadenschlaufe 42a mittels des Webblattes 11 an der Anschlagkante 10, wie in Figur 5 dargestellt ist. Nach dem Fachwechsel folgt das Eintragen der Schussfadenschlaufe an der rechten Seite des Bandes, wobei der Vorgang analog dem Eintrag des Schussfadens an der linken Bandseite erfolgt. Figures 5 to 7 show a needle loom, which is constructed analogously to the needle loom of Figures 1 to 4, so that in the first embodiment, the same parts are provided with the same reference numerals. Reference is made to the relevant embodiments in Figures 1 to 4. In the embodiment of FIGS. 5 to 7, however, no auxiliary threads are used, but the weft threads 40a, 40b are meshed with themselves. FIG. 6 shows how the weft thread loop 42a from the weft thread 40a will enter into the shed by means of the left weft needle 2a. After the complete entry, the right knitting needle 28b detects the inserted weft thread loop 42a and pulls it through the weft thread loop 42a, which has already been knocked off. During insertion of the weft loop 42a by means of the weft needle 2a from the left side of the tape, the right weft needle 2b moves empty through the warp shed. The weft thread 40b is guided in the guide slot 20b of the right weft needle 2b, as can be seen from FIG. As soon as the weft needles 2a, 2b are withdrawn from the warp shed, the abutment of the inserted weft loop 42a takes place by means of the reed 11 at the stop edge 10, as shown in FIG. After changing the tray follows the insertion of the weft loop on the right side of the tape, the process is analogous to the entry of the weft thread on the left side of the tape.
