Abstract

Process for producing fabrics, in particular multilayer fabrics on a loom, whereby in order to achieve extremely careful insertion of the picks even at high pickages, the pickages are above 20 picks/cm, the individual picks are not first beaten up, and beating-up is effected only after insertion of a complete set of picks consisting of several picks of a specified number.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstel­lung von Geweben, insbesondere Mehrlagengeweben, mittels einer Web­maschine, hergestellt ganz oder übergewichtig aus hochempfindlichen, technischen Fasern, wie Kohle-Fasern, Glas-Fasern oder dergleichen, ferner ein daraus hergestelltes Gewebe in seiner Struktur.The invention relates to a method and a device for producing fabrics, in particular multi-layer fabrics, by means of a weaving machine, made entirely or overweight from highly sensitive, technical fibers, such as carbon fibers, glass fibers or the like, and also a fabric made therefrom in its structure.

Aus der GB-PS 20 66 308 sind dreidimensionale Gewebe bekannt, bei denen Kohle-Fasern oder Glas-Fasern Verwendung finden. Ebenso ist es bekannt, bei Kohlestoff-Fasern einen Bewegungsablauf vorzusehen, der schlagartige Beanspruchungen vermeidet, um der extremen Sprödigkeit, welche durch deren Temperaturkoeffizient nahe Null bedingt ist, Rech­nung zu tragen.From GB-PS 20 66 308 three-dimensional fabrics are known in which carbon fibers or glass fibers are used. It is also known to provide a movement sequence in the case of carbon fibers which avoids sudden stresses in order to take account of the extreme brittleness which is caused by their temperature coefficient close to zero.

Ebenso ist aus der EP 00 56 351 ein Flächengewebe bekannt, welches aus hochfestem Material besteht, wie z. B. Metall, Kohle-Fasern, Aramiden oder Gemischen daraus usw. Dieses Flächengewebe wird in eine bestimmte Form gebracht.Also known from EP 00 56 351 is a flat fabric, which consists of high-strength material, such as. B. metal, carbon fibers, aramids or mixtures thereof, etc. This flat fabric is brought into a certain shape.

Bei den bekannten Lösungen ist das erzielbare Ergebnis unbefriedigend, wie gefunden wurde deshalb, weil auf herkömmlichen Webmaschinen dabei jeder ins Webfach eingetragene Schußfaden nach dem Eintrag desselben an den Warenrand angeschlagen wird. Hierbei wird durch die Stäbe des Webblattes bei jedem Schußeintrag sowohl bei der Vorwärts- als auch bei der Rückwärtsbewegung des Webblattes an den Kettfäden gerieben. Bei hohem bzw. sehr hohem Schußdichten und dem zugehörigen Hub des Webblattes besteht eine Proportionalität zwischen Blattbewegung, Kette, Schußdichte und Ladenhub.In the known solutions, the achievable result is unsatisfactory, as has been found because, on conventional weaving machines, every weft thread entered into the shed is struck on the edge of the goods after the entry thereof. In this case, the rods of the reed rub against the warp threads with each weft insertion during both the forward and backward movement of the reed. At high or very high weft density and the associated stroke of the reed there is a proportionality between leaf movement, chain, weft density and loading stroke.

Um Aufscheuerungen am hochempfindlichen Kettmaterial entgegenzuwirken, ist es bekannt, mit nachgedrehtem Kettmaterial bzw. mit faserumwundenem Kettmaterial zu arbeiten. Dies führt jedoch zu in vielen Fällen untrag­baren Festigkeitsminderungen, jedenfalls relativ gesehen bezüglich des gesamten Gewebes.In order to counter abrasion on the highly sensitive warp material, it is known to work with twisted warp material or with fiber-wrapped warp material. However, this leads to intolerable reductions in strength in many cases, at least in relative terms with regard to the entire fabric.

Die Erfindung hat zur Aufgabe, unter Vermeidung der vorgenannten Nachteile, ein Verfahren und eine Vorrichtung und mit beiden ein Gewebe zu schaffen, bei dessen Herstellung keine Beeinträchtigung der hochem­pfindlichen Kettfäden selbst bei hohen Schußdichten vorliegt.The object of the invention, while avoiding the aforementioned disadvantages, is to provide a method and an apparatus, and with both a fabric, in the production of which there is no impairment of the highly sensitive warp threads even at high weft densities.

Gelöst ist diese Aufgabe durch das Kennzeichen des Hauptanspruches. Die Unteransprüche stellen vorteilhafte Weiterbildungen dar.This task is solved by the characteristic of the main claim. The subclaims represent advantageous developments.

Die erfinderische Lösung hat den Vorteil, daß aus hochempfindlichen Garnen der genannten Art unter Einbeziehung entsprechender Bindungen mit Schußdichten von 20 bis über 150 Schuß/cm gearbeitet werden kann und somit die Herstellung von in Kette und Schuß sehr dicht eingestellten technischen Geweben in dreidimensionaler Anordnung (Mehrlagengewebe) ermöglicht wird. Selbst bei entsprechend hoher Anzahl von Schüssen sind die Reibungen der Blattstäbe an den Kettfäden so erheblich verminderbar, daß Beschädigungen am Gewebe vermieden sind. Dies gilt insbesondere bei höchst empfindlichen Materialien für die Kettfäden, so daß -wie ge­funden wurde- gerade dort eine Festigkeitsminderung durch Beschädi­gungen von Einzelkapillaren des Fadens nicht mehr auftritt. Vornehmlich bei Mehrlagengeweben kommt man dadurch zu einem optimalen Produkt. Webt man dies mit Randzonen, deren Kettfäden weniger empfindlich und deren Schußfäden nach jedem Eintrag angeschlagen werden, so kommt man zu einem optimal beschädigungsfrei hergestellten Zwischenprodukt, bei dem die Randbereiche zweidimensional und leicht mit nur geringem Verlust abgeschnitten werden können und der mittlere Mehrlagenbereich weiter­verwendet werden kann.The solution according to the invention has the advantage that weft densities of 20 to over 150 weft / cm can be worked from highly sensitive yarns of the type mentioned, including the appropriate bonds, and thus the production of technical fabrics in warp and weft in a three-dimensional arrangement (multi-layer fabric ) is made possible. Even with a correspondingly high number of wefts, the friction of the leaf bars on the warp threads can be reduced so considerably that damage to the fabric is avoided. This is especially true in the case of highly sensitive materials for the warp threads, so that, as has been found, a decrease in strength due to damage to individual capillaries of the thread no longer occurs there. This leads to an optimal product, especially for multi-layer fabrics. If you weave this with marginal zones, the warp threads of which are less sensitive and the weft threads are attached after each entry, you get an intermediate product that is optimally produced without damage, in which the marginal areas can be cut off two-dimensionally and easily with little loss and the middle multi-layer area can be used again .

Die Erfindung ist in der Zeichnung dargestellt und wird in der nach­folgenden Beschreibung näher erläutert. Es zeigt:

  • Fig. 1 den schematischen Aufbau eines Webstuhls mit den erfinderischen Einbauten (in eindeutiger Darstellung),
  • Fig. 2 einen Ausschnitt einer Webmaschine, in der die Positionierung und Arretierung des Webblatthalters schematisch dargestellt ist,
  • Fig. 3 einen Ausschnitt im Bereich der Endschalter-Steuerung einer Webmaschine nach Fig. 1.
The invention is illustrated in the drawing and is explained in more detail in the description below. It shows:
  • 1 shows the schematic structure of a loom with the inventive fixtures (in a clear representation),
  • 2 shows a detail of a weaving machine, in which the positioning and locking of the reed holder is shown schematically,
  • 3 shows a detail in the area of the limit switch control of a weaving machine according to FIG. 1.

Die starren Verbindungen in Form von Wellenkupplungen zwischen Ge­triebewelle 1 und Blattantriebswelle 2 -Bild 1- wurden durch Kupplungen 3 -Bild 1- ersetzt. Die Steuerung der Kupplungen erfolgt synchron mittels hier erwähnter herkömmlicher Verfahren: Papier-Lochkarte von der Schaftmaschine oder einer handelsüblichen Farbwählvorrichtung.The rigid connections in the form of shaft couplings between gear shaft 1 and blade drive shaft 2 Figure 1- have been replaced by couplings 3 Figure 1-. The clutches are controlled synchronously using the conventional methods mentioned here: punched paper card from the dobby or a commercially available color selection device.

Hierbei bedeutet:
Loch = Schließen der Kupplung - Blattanschlag nach Shußein­trag
kein Loch = Öffnen der Kupplung - kein Blattanschlag
oder auch umgekehrt.Here means:
Hole = closing the clutch - blade stop after entry of shot
no hole = opening of the clutch - no blade stop
or vice versa.

Da die Getriebewellen unabhängige von dieser Steuerung in jedem Falle die intermittierende Bewegung für den Blattanschlag durchführen, werden die beiden äußeren Ladenstützen ausgebüchst, so daß dieselben nicht mehr zum Blattantrieb, sondern nur noch zur Blattstützung verwendet werden.Since the gear shafts carry out the intermittent movement for the leaf stop independently of this control, the two outer shop supports are bushed out, so that they are no longer used for leaf drive, but only for leaf support.

An den dem rechten und linken Getriebe zugewandten Kupplungsteilen, welche die ständige intermittierende Bewegung der Getriebewellen mit­machen, sind die Blattsegmenthalter 4 -Bild 1- angeschraubt, welche die Blattsegmente 9 -Bild 1- in Breite der Warenkante aufnehmen.On the coupling parts facing the right and left gears, which participate in the constant intermittent movement of the gear shafts, the blade segment holders 4-image 1- are screwed, which hold the blade segments 9-image 1- in the width of the goods edge.

Die Blattsegmente, welche unmittelbar rechts und links vom Webblatt arbeiten, übernehmen nach jedem Schußeintrag den Anschlag desselben an die rechte und linke Warenkante, deren Kettfäden aus einem unempfind­lichen Material bestehen.The leaf segments, which work directly to the right and left of the reed, take over after each weft entry the stop on the right and left goods edge, the warp threads of which are made of an insensitive material.

Durch diese Einrichtung wird erreicht, daß jeder Schußfaden in dem Fall, daß kein regulärer Blattanschlag erfolgt, ca. 1-3 cm vor dem Warenrand abgelegt wird.This device ensures that each weft thread, in the event that there is no regular leaf stop, is deposited about 1-3 cm in front of the edge of the goods.

Entsprechend gewählten Bindungskonstruktionen können so mehrere Schüsse eingetragen werden, welche als Schußgruppe gemeinsam nach dem Schließen der Kupplungen mit einem Blattanschlag an den Warenrand angeschlagen werden. Durch entsprechende Steuerung des Positions­schalters am Farbwähler (hier nicht dargestellt) über den Endschalter 8 -Bild 3- wird erreicht, daß das Öffnen und Schließen der Zahnkupplungen nur bei Stillstand des Blattes in hinterster Stellung möglicht ist.According to selected binding constructions, several shots can be entered, which as a group of shots are struck together at the edge of the goods with a blade stop after the couplings have been closed. By appropriate control of the position switch on the color selector (not shown here) via the limit switch 8 Figure 3- it is achieved that the opening and closing of the toothed couplings is only possible when the blade is in the rearmost position.

Die exakte Positionierung sowie die Arretierung der Webblatthalterung bei geöffneter Zahnkupplung wird durch den elektrischen Haltemagneten 6 mit Stellplatte 7 -Bild 1 und 2- erreicht, wobei die elektrische Schaltung so aufgebaut ist, daß Haltemagnet und Zahnkupplung synchron arbeiten.The exact positioning and locking of the reed holder when the tooth coupling is open is achieved by the electrical holding magnet 6 with the setting plate 7, Figures 1 and 2-, the electrical circuit being constructed in such a way that the holding magnet and tooth coupling work synchronously.

Das Prinzip des periodischen Blattanschlags ist abzustimmen auf bestimmte Bindungskonstruktionen. Insbesondere ist dieses Prinzip geeignet für die Erzeugung von Mehrlagengeweben, welche so aufgebaut sind, daß perio­disch mehrere Schaftwechsel hintereinander nur von obennach unten oder nur von unten nach oben erfolgen.The principle of periodic leaf stroke is to be matched to certain binding constructions. In particular, this principle is suitable for the production of multi-layer fabrics which are constructed in such a way that periodically several shaft changes are carried out successively only from top to bottom or only from bottom to top.

Das Ziel der größtmöglichen Schonung des Kettmaterials beim Weben wird umsomehr erreicht, je weniger Blattanschläge im Verhältnis zur einge­tragenen Schußzahl erfolgen.The goal of the greatest possible protection of the warp material during weaving is achieved all the more, the fewer blade stops in relation to the number of wefts entered.

Die Anzahl der mittels periodischen Blattanschlags als Schußgruppe gleich­zeitig an den Warenrand anzuschlagenden Schüsse richtet sich nach der Bindungskonstruktion und kann mindestens 2 und maximal bis zu mehr als 10 Schüsse betragen.The number of shots to be fired at the edge of the goods at the same time by means of periodic sheet firing as a group depends on the construction of the binding and can be at least 2 and at most up to more than 10 shots.

Ohne Blattanschlag können jeweils so viele Schüsse eingetragen werden, wie Fachwechsel ohne sich kreuzende Kettfäden erfolgen.Without a leaf stop, as many shots can be entered as there are shed changes without intersecting warp threads.

Dies geschieht,

  • 1. insbesondere bei Mehrlagengeweben, bei denen die Schüsse in mehreren Ebenen eingetragen werden, wobei Schaftwechsel nur von oben nach unten oder nur von unten nach oben erfolgen,
  • 2. bei Eintrag von zwei oder mehreren Schüssen in ununterbroche­ner Reihenfolge in das gleiche Webfach.
This happens,
  • 1. in particular in the case of multi-layer fabrics in which the wefts are entered in several planes, the shafts being changed only from top to bottom or only from bottom to top,
  • 2. when two or more shots are entered in the same shed in uninterrupted order.

Zur Webfachbildung mit sich kreuzenden Kettfäden muß der Blattanschlag folgen.The leaf stop must follow to form the shed with intersecting warp threads.

Es wurde gefunden, daß die Gestaltungsmerkmale des fertigen Gewebes, welches diese besitzt aufgrund der Tatsache, daß seitliche Randzonen nach jedem Schuß, der mittlere Bereich aber nur nach Eintragung jeweils einer Schußgruppe bestimmter Größe angeschlagen wurde, insbesondere im Bereich der technischen Gewebe, deren Verwendung nicht beeinträchti­gen. Zur Anpassung an bestimmte Verwendungen oder zur Optimierung des Verhältnisses Volumen/Festigkeit können nach dem Weben bspw. auch die mit normalen, wenig empfindlichen Kettfäden ausgestatteten Randzonen ganzbreitig oder in einer Teilbreite abgeschnitten werden.It was found that the design features of the finished fabric, which it possesses due to the fact that lateral edge zones were struck after each shot, but the middle area only after the entry of a respective group of wefts of a certain size, especially in the area of technical fabrics, their use was not affect. In order to adapt to certain uses or to optimize the volume / strength ratio, after weaving, for example, the edge zones equipped with normal, less sensitive warp threads can also be cut off in full or in part.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den An­sprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
