Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Bilden einer Dreherkante zum Einsatz auf einer Jacquard-Maschine.The invention relates to a device for forming a leno edge for use on a jacquard machine.
Jacquard-Maschinen dienen der Herstellung des sogenannten Jacquardgewebes. Jacquardgewebe ist der Sammelbegriff für alle Gewebe mit einer Bindungsmusterung, die nur durch das Anheben einzelner Webfäden hervorgerufen werden kann. Typische Jacquardgewebe sind beispielsweise Damast und Brokat. Zur Herstellung eines bestimmten Musters muß hierfür die einzelne Anhebung einer dem Musterumfang entsprechenden Anzahl von Kettfäden je Schußeintrag bestimmt werden. Die Anhebung der gleich einbindenden Steherfäden erfolgt durch Harnischschnüre, die an Platinen befestigt sind. Die Platinen werden von den Hebemessern angehoben. Die Auswahl des Anhebens der jeweiligen Platinen erfolgt durch die Nadeln, die wiederum durch die Karten gesteuert werden.Jacquard machines are used to manufacture the so-called jacquard fabric. Jacquard fabric is the collective term for all fabrics with a weave pattern that can only be created by lifting individual weaving threads. Typical jacquard fabrics are, for example, damask and brocade. To produce a specific pattern, the individual raising of a number of warp threads per weft entry corresponding to the pattern size must be determined. Harness cords attached to printed circuit boards are used to raise the upright threads that bind in the same way. The boards are raised by the lifting knives. The choice of lifting the respective boards is made by the needles, which in turn are controlled by the cards.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Bilden einer Dreherkante zum Einsatz auf einer Jacquard-Maschine zu schaffen.The invention has for its object to provide a device for forming a leno edge for use on a jacquard machine.
Dies Aufgabe wird erfindungsgemäß durch einen Dreherkantenapparat erreicht, der unmittelbar mit den Harnischschnüren der Jaquard-Maschine verbunden ist. Nach einer besonderen Ausführungsform ist zur Aufnahme des Dreherkantenapparates eine Halterung vorgesehen.This object is achieved according to the invention by means of a leno selvedge device which is directly connected to the harness cords of the Jaquard machine. According to a special embodiment, a holder is provided for receiving the leno selvedge apparatus.
Der Dreherkantenapparat besteht nach einem weiteren Merkmal der Erfindung bei jeder der beiden Ausführungsformen aus mindestens zwei Hebelitzen und einer durch die Hebelitzen geführten und von jeweils der einen Hebelitze mitgenommenen Halblitze.According to a further feature of the invention, the leno selvedge apparatus in each of the two embodiments consists of at least two lifting healds and one half-heald guided through the lifting healds and carried along by one lifting heald.
Bei der ersten Ausführungsform sind die Hebelitzen an ihren oberen Enden mit den Harnischschnüren verbunden; an den unteren Enden sind die Hebelitzen vertikal beweglich, beispielsweise durch Federn, gehalten.In the first embodiment, the lifting strands are connected to the harness cords at their upper ends; at the lower ends the lifting healds are vertically movable, for example by means of springs.
Die Halterung für die Hebelitzen besteht hierbei aus zwei vertikal bewegbaren Trägern, wobei die Träger durch mindestens einen Führungsarm in Längsrichtung geführt sind. Zur Aufnahme der Hebelitzen besitzt jeder Träger zwei mit vertikalem Abstand zueinander angeordnete Tragschienen. Um den Einsatz unterschiedlich langer Hebelitzen zu ermöglichen, sind die Träger in ihrer Länge verstellbar ausgebildet. Hierfür ist jeder Träger geteilt und jedes Trägerteil eines Trägers mit einer sich gegenüberliegenden Bohrung zur Aufnahme eines Verlängerungsstiftes versehen. Der Verlängerungsstift ist hierbei durch Klemmschrauben in den Trägerteilen fixierbar.The bracket for the lifting healds here consists of two vertically movable supports, the supports being guided in the longitudinal direction by at least one guide arm. To accommodate the lifting strands, each carrier has two support rails arranged at a vertical distance from one another. In order to enable the use of lifting strands of different lengths, the supports are adjustable in length. For this purpose, each carrier is divided and each carrier part of a carrier is provided with an opposite bore for receiving an extension pin. The extension pin can be fixed in the carrier parts by means of clamping screws.
Die Träger selbst weisen an ihren oberen Enden jeweils eine Öse zur Aufnahme einer Harnischschnur auf, die die vertikale Bewegung der Träger bewirkt. Jeder Träger ist an seinem unteren Ende durch ein Federelement, z.B. eine Feder, gehalten, um die Rückstellung des Trägers nach Auslenkung durch die Harnischschnur zu gewährleisten. Die Federelemente sind hierbei an einem an dem Halteelement befestigten Ausleger angeordnet. Im übrigen weist das Halteelement einen Niederhalter für den Steherfaden auf, der diesen immer in Richtung Fachoffenstellung hält.The straps themselves each have an eyelet at their upper ends for receiving a harness cord, which causes the straps to move vertically. Each carrier is held at its lower end by a spring element, for example a spring, in order to ensure the return of the carrier after deflection by the harness cord. The spring elements are arranged on a bracket attached to the holding element. For the rest, the holding element has a hold-down device for the upright thread, which always holds it in the direction of opening the compartment.
Die Halblitze besteht im wesentlichen aus zwei Schenkeln, die an ihrem einen Ende eine geschlossene Öse zur Führung des Dreherfadens bilden. Jeder Schenkel der Halblitze wird durch eine in der Hebelitze angeordnete Führungsöffnung geführt, die durch zwei seitlich übereinander versetzt angeordnete Stege gebildet wird. Die Hebelitzen können nach einer Einbaumöglichkeit so an den Tragschienen angehängt sein, daß die Halblitze mit ihrer Öse nach oben zeigt. Die Steuerung der Halblitze in den Hebelitzen erfolgt in diesem Fall sowohl durch die auf die Halblitze wirkende Schwerkraft, als auch durch die entsprechende Vorspannung des durch die Öse geführten Dreherfadens. Es ist unmittelbar einsichtig, daß die Steuerung der Halblitze durch die entsprechende Vorspannung des Dreherfadens auch ohne die zusätzliche Einwirkung der Schwerkraft erfolgt, wenn nämlich die Hebelitzen mit der Halblitze so an den Tragschienen befestigt sind, daß die Halblitze mit ihrer Öffnung nach unten zeigt.The half-strand consists essentially of two legs, which form a closed eyelet at one end for guiding the leno thread. Each leg of the half-strand is guided through a guide opening arranged in the lifting strand, which is formed by two webs which are laterally offset one above the other. After installation, the lifting strands can be attached to the mounting rails so that the half-strands point upwards with their eyelets. In this case, the control of the half strands in the lifting strands is carried out both by the force of gravity acting on the half strands and by the corresponding pretensioning of the leno thread passed through the eyelet. It is immediately apparent that the control of the half strands by the corresponding pretension of the leno thread takes place without the additional action of gravity, namely when the lifting strands are attached to the mounting rails with the half strands so that the half strands point with their opening downwards.
Nach einer besonders vorteilhaften Ausführungsform sind zur Steuerung der Halblitze Steuerungsmittel vorgesehen. Bei dieser Ausführungsform ist ebenso wenig der Einfluß der Schwerkraft, als auch die Vorspannung des Dreherfadens von einer wesentlichen Bedeutung, denn durch die Steuerungsmittel wird unter allen Umständen gewährleistet, daß die Halblitze von den Hebelitzen jeweils wechselseitig mitgenommen wird.According to a particularly advantageous embodiment, control means are provided for controlling the half-strands. In this embodiment, the influence of gravity and the pretension of the leno thread are of no great importance, because the control means ensure under all circumstances that the half-strand is alternately carried along by the lifting strands.
Nach einer besonders vorteilhaften Unterform zu dieser Ausführungsform sind die Mittel zur Steuerung der Halblitze in den Hebelitzen angeordneten Magnete.According to a particularly advantageous lower mold for this embodiment, the means for controlling the half strands in the lifting strands are magnets.
Hierbei entspricht der Abstand der in der Hebelitzen angeordneten Magnete von dem innenliegenden Steg der Führungsöffnung in etwa der Schenkellänge der Halblitze. Um die Magnetkraft zur Steuerung aufbauen zu können, muß die Halblitze aus einem magnetischen Metall bestehen, oder eine entsprechende Einlage aufweisen. Selbst bei hoher Hubzahl gewährleistet diese Vorrichtung immer eine exakte Steuerung der Halblitze.Here, the distance of the magnets arranged in the lifting healds from the inner web of the guide opening corresponds approximately to the leg length of the half heald. In order to be able to build up the magnetic force for control, the half strands must consist of a magnetic metal or have an appropriate insert. Even with a high number of strokes, this device always ensures precise control of the half strands.
Vorteilhaft ist weiterhin, daß hierbei der Verschleiß an dem innenliegenden Steg der Führungsöffnung einer Hebelitze durch die während der Mitnahme auf den Steg der Halblitze wirkende Kraft nur gering ist, da im Gegensatz zu der bekannten Ausführungsform einer Steuerung mit Litzentragschiene und Feder dieser Steg der Führungsöffnung der Hebelitze nur zum Zeitpunkt der Einleitung der Umkehrbewegung unter der Einwirkung der durch die Magnete hervorgerufenen Kraft steht. Die Einwirkung der Gewichtskraft der Halblitze auf den Verschleiß des Steges ist hierbei vernachlässigbar gering.It is also advantageous that here the wear on the inner web of the guide opening of a lifting wire is only slight due to the force acting on the web of the half-wire during driving, since in contrast to the known embodiment of a control with a heddle support rail and spring, this web of the guide opening The lifting wire is only under the influence of the force caused by the magnets at the time the reversal movement is initiated. The influence of the weight of the half strands on the wear of the web is negligible.
Nach einer weiteren Unterform zu der zweiten Ausführungsform ist die Halblitze mit den Hebelitzen bzw. den Tragschienen selbst zur Steuerung durch elastische Mittel, z.B. Gummizüge, verbunden.According to a further sub-form to the second embodiment, the half-strand with the lifting strands or the mounting rails itself is for control by elastic means, e.g. Elastic bands, connected.
Gegenstand der Erfindung ist ebenfalls die Verwendung eines Dreherkantenapparates, bestehend aus mindestens zwei Hebelitzen und einer durch die Hebelitzen geführten und von jeweils der einen Hebelitze durch Steuerungsmittel mitgenommenen Halblitze zur Erstellung einer Dreherkante an einem auf einer Jaquard-Maschine hergestellten Gewebe.The invention also relates to the use of a leno edging apparatus, consisting of at least two lifting healds and a half heald guided through the lifting healds and carried along by one lifting heald by control means for creating a leno edge on a fabric produced on a Jacquard machine.

Gemäß den Figuren 2 bis 5 sind die Hebelitzen jeweils mit 1 und 2 bezeichnet, die von den Hebelitzen geführte Halblitze jeweils mit 3. Die Hebelitzen 1 und 2 weisen endseitig Mittel 4a bis 4d zur Befestigung an den wechselseitig bewegten Tragschienen 5a bis 5d auf. Jede Hebelitze 1 bzw. 2 besitzt eine Führungsöffnung 6, 7, die durch die Stege 6a, 6b bzw. 7a, 7b gebildet wird. Die Halblitze 3 besteht im wesentlichen aus zwei Schenkeln 3a und 3b, die an ihrem oberen Ende eine geschlossene Öse 8 zur Führung des Dreherfadens 19 bilden.According to FIGS. 2 to 5, the lifting strands are each designated 1 and 2, the half strands guided by the lifting strands are each designated 3. The
Nach der in Fig. 1 dargestellten ersten Ausführungsform erfolgt die Steuerung durch in dem Mantel 20, 21 der Hebelitzen 1, 2 angeordnete Magnete 9, 10. Die Mitnahme der Halblitze 3 selbst erfolgt jeweils durch den die Halblitze 3 im Bereich der Öse 8 erfassenden innenliegenden Steg 6b bzw. 7b der Führungsöffnung 6 bzw. 7. Um eine einwandfreie Steuerung und Mitnahme der Halblitze durch die Hebelitzen zu gewährleisten, beträgt der Abstand zwischen dem Magneten 9 bzw. 10 und dem innenliegenden Steg 6b bzw. 7b einer jeden Führungsöffnung 6 bzw. 7 etwa die Länge eines Schenkels 3a, 3b der Halblitze 3.According to the first embodiment shown in FIG. 1, the control is carried out by
Anstelle der Magnete sind nach einer zweiten Ausführungsform zur Steuerung Gummizüge 11, 12 vorgesehen, durch die die Schenkel 3a, 3b der Halblitze mit den Hebelitzen verbunden sind (Fig. 2, Fig. 4).Instead of the magnets, in accordance with a second embodiment for control purposes,
Die Ausführungsform gemäß Fig. 4 unterscheidet sich von der gemäß Fig. 2 lediglich dadurch, daß hierbei die Gummizüge 13, 14 durch Klemmittel 15, 16 unmittelbar mit den Webschäften 5c, 5d verbunden sind.The embodiment according to FIG. 4 differs from that according to FIG. 2 only in that the
Der Steuerungsvorgang selbst entspricht hierbei dem der ersten Ausführungsform.The control process itself corresponds to that of the first embodiment.
Bei der Ausführungsform gemäß Fig. 3 erfolgt die Steuerung lediglich durch die auf der Halblitze 3 einwirkende Schwerkraft und die entsprechende Vorspannung des durch die Öse 8 der Halblitze 3 geführten Dreherfadens. Die Führung und Mitnahme der Halblitze erfolgt hierbei wiederum durch die Stege 6b bzw. 7b der Führungsöffnungen 6 bzw. 7.In the embodiment according to FIG. 3, the control takes place only through the force of gravity acting on the half-
Um den schon geringen Verschleiß an den innenliegenden Stegen 6b bzw. 7b noch weiter zu vermindern, weisen diese Stege Verstärkungseinlagen 17, 18, z.B. aus Metall, auf.In order to further reduce the already slight wear on the
Die insgesamt mit 22 bezeichnete Halterung zur Aufnahme der Hebelitzen 1, 2 besteht aus einem Halteelement 23 und einem Trägerpaar 24, 25, die durch zwei Führungsarme 25, 27 von dem Halteelement 23 gehalten werden. Jeder Träger 24, 25 besitzt zwei in vertikaler Richtung beabstandet zueinander angebrachte Tragschienen 5a, 5b, 5c, 5d, an die die Hebelitzen 1, 2 angehängt werden.
