The nap threads (14) of the above triple web are separated between the middle web (8) and a first web (10) in a first cutting device (36, 36a). In a second cutting device (46, 46a) the nap threads between the middle web (8) and the second web (12) are separated to give the middle web as a double-sided velvet ribbon (8). The corresponding ribbon weaving machine (2) comprises three superimposed weaving points (31) each with a weft introduction body and a common shedding device (16). A first cutting device (36) for cutting the nap threads (14a) between the middle web (8) and a first web (12) and a second cutting device (46) for cutting the nap threads (14b) between the middle web (8) and the second web (10) are provided afterwards. The velvet ribbon (8) produced thus has a nap (56, 58) on both sides.

Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Verfahren zum Herstellen eines Samtbandes mit doppelseitigem Flor, gemäß Anspruch 1, eine Bandwebmaschine zur Durchführung des Verfahrens, gemäß Anspruch 5, sowie ein so hergestelltes Samtband.The invention relates to a method for producing a velvet tape with double-sided pile, according to claim 1, a ribbon loom for carrying out the method, according to claim 5, and a so-produced velvet ribbon.

Stand der TechnikState of the art

Aus der CH 554 431 ist es bekannt, auf einer schiffchenlosen Bandwebmaschine Samtbänder herzustellen, wobei zwei mit Abstand übereinander liegende Bänder hergestellt werden, die durch Florfäden miteinander verbunden sind. Auf halbem Abstand zwischen den einzelnen Bändern werden die Florfäden durchtrennt und man erhält zwei Samtbänder, die auf einer Seite einen Flor aufweisen. Die Druckschrift enthält keinerlei Hinweise auf die Möglichkeit, ein doppelseitiges Samtband herzustellen.From the CH 554 431 It is known to produce velvet ribbons on a shipless ribbon loom, wherein two spaced-apart bands are produced, which are interconnected by pile threads. At half the distance between the bands, the pile threads are severed and you get two velvet ribbons, which have a pile on one side. The document contains no indication of the possibility to produce a double-sided velvet ribbon.

Darstellung der ErfindungPresentation of the invention

Aufgabe der Erfindung ist es, ein Verfahren zum Herstellen eines doppelseitigen Samtbandes und eine Bandwebmaschine zur Durchführung eines solchen Verfahrens anzugeben sowie ein nach dem Verfahren bzw. auf der Bandwebmaschine hergestelltes doppelseitiges Samtband zu schaffen.The object of the invention is to provide a method for producing a double-sided velvet ribbon and a ribbon loom for carrying out such a method and to provide a produced by the method or on the ribbon loom double-sided velvet ribbon.

Die Aufgabe wird erfindungsgemäß gelöst durch:

  1. a) ein Verfahren zur Herstellung eines Samtbandes nach Anspruch 1;
  2. b) eine Bandwebmaschine zur Durchführung des Verfahrens nach Anspruch 5; sowie
  3. c) ein Samtband das sich aus dem Verfahren von a), auf einer machine nach b), ergibt (siehe artikel 64(2)EPÜ).
The object is achieved according to the invention by:
  1. a) a method for producing a velvet ribbon according to claim 1;
  2. b) a ribbon loom for carrying out the method according to claim 5; such as
  3. c) a velvet ribbon resulting from the process of (a) on a machine according to (b) (see Article 64 (2) EPC) .

Dadurch, dass man drei In gegenseitigem Abstand übereinander liegende Bänder webt und diese durch Florfäden miteinander verbindet, erhält man ein mittleres Band, das beidseitig Florfäden aufweist sowie ein oberes und unteres Band, das jeweils nur einseitig mit einem Flor versehen ist. Zunächst wird an einer ersten Schneidvorrichtung zwischen dem mittleren Band und einem ersten Band die Florfäden durchschnitten und dann an einer zweiten Schneidvorrichtung die florfäden zwischen dem mittleren Band und dem zweiten Band getrennt. Das mittlere Band liefert dann das gewünschte zweiseitige Samtband, während das obere und das untere Band als Abfall abgeführt werden.By weaving three bands lying one above the other at a mutual distance and connecting them by pile threads, one obtains a middle band which has pile threads on both sides and an upper and lower band which each is provided only on one side with a pile. First, the pile threads are cut at a first cutting device between the middle band and a first band and then separated at a second cutting device, the pile threads between the middle band and the second band. The middle band then provides the desired two-sided velvet ribbon, while the upper and lower bands are discharged as waste.

Zur Herstellung eignen sich verschiedene Verfahren; besonders vorteilhaft ist das Verfahren nach Anspruch 2, bei dem man das Dreifachband auf einer Nadelbandwebmaschine herstellt. Es ist denkbar, das Dreifachband unabhängig von der Bandwebmaschine weiterzuverarbeiten; vorteilhafter ist es jedoch, wenn man nach Anspruch 3 das Schneiden der Florfäden unmittelbar nach dem Weben auf der Bandwebmaschine durchführt. Grundsätzlich ist es möglich, das Schneiden der Florfäden mit zwei voneinander unabhängigen Schneidvorrichtungen durchzuführen, die nacheinander angeordnet sind. Vorteilhafter ist es, wenn die erste und die zweite Schneidvorrichtung gemäss Anspruch 4 nebeneinander angeordnet sind, wobei das einmal geschnittene Band von der ersten Schneidvorrichtung zur zweiten Schneidvorrichtung zurückgeführt werden muss. Dies ermöglicht eine einfache und besonders kurze Bauform der Schneidvorrichtung.For the preparation, various methods are suitable; Particularly advantageous is the method according to claim 2, wherein the triple band is produced on a needle loom. It is conceivable to process the triple band independently of the ribbon loom; However, it is more advantageous if according to claim 3, the cutting of the pile threads immediately after weaving on the ribbon loom performs. In principle, it is possible to perform the cutting of the pile threads with two independent cutting devices, which are arranged one after the other. It is more advantageous when the first and the second cutting device according to claim 4 are arranged side by side, wherein the once cut tape must be returned from the first cutting device to the second cutting device. This allows a simple and very short design of the cutting device.

Die Bandwebmaschine zur Herstellung des Bandes weist gemäß Anspruch 5 drei mit Abstand voneinander und übereinander liegende Webstellen mit je einem Schusseintragorgan und einer Fachbildevorrichtung zur Öffnung von drei Webfächern und zum Legen von die Webstellen verbindenden Florfäden auf. Der Webstelle sind eine erste Schneidvorrichtung zum Schneiden der Florfäden zwischen dem mittleren Band und einem ersten Band und eine zweite Schneidvorrichtung zum Schneiden der Florfäden zwischen dem mittleren Band und dem zweiten Band nachgeschaltet.The ribbon loom for the production of the tape has according to claim 5 three spaced apart and superimposed weaving sites, each with a weft insertion member and a shedding device for opening three sheds and laying of the weaves connecting pile threads on. The weaving station is followed by a first cutting device for cutting the pile threads between the middle strip and a first strip and a second cutting device for cutting the pile threads between the middle strip and the second strip.

Um ein exaktes Schneiden der Florfäden auf einer bestimmten florhöhe zu ermöglichen, ist es gemäß Anspruch 6 von Vorteil, wenn an den Schneidvorrichtungen jeweils Führungen für das Band angeordnet sind, die im Niveau und/oder im gegenseitigen Abstand einstellbar sind.In order to enable an exact cutting of the pile threads at a certain florhöhe, it is advantageous according to claim 6, when each guide for the band are arranged on the cutting devices, which are adjustable in level and / or in the mutual distance.

Besonders vorteilhaft ist eine Bandwebmaschine nach Anspruch 7, wobei die erste und die zweite Schneidvorrichtung nebeneinander angeordnet sind, und der ersten Schneidvorrichtung Umlenkmittel zur Rückführung des Bandes zur zweigen Schneidvorrichtung zugeordnet sind. Dies ermöglicht es, gemäß Anspruch 8 den beiden Schneidvorrichtungen ein gemeinsames Schneidorgan zuzuordnen. Dabei kann das Schneidorgan gemäß Anspruch 9 als hin- und hergehend angetriebenes Schneidmesser ausgestaltet sein. Gemäß Anspruch 10 ist auch ein Schneidorgan möglich, das als umlaufendes Schneidband ausgebildet ist. Zweckmäßigerweise ist den Schneidorganen gemäß Anspruch 11 eine Schleifvorrichtung zugeordnet, wie dies aus der CH 554 431 bekannt ist.Particularly advantageous is a ribbon loom according to claim 7, wherein the first and the second cutting device are arranged side by side, and the first cutting device are associated with deflection means for returning the tape to the two cutting device. This makes it possible, according to claim 8 to assign the two cutting devices a common cutting member. In this case, the cutting member may be configured according to claim 9 as reciprocally driven cutting blade. According to claim 10, a cutting member is possible, which is designed as a rotating cutting band. Appropriately, the cutting members according to claim 11 associated with a grinding device, as is known from CH 554 431 is known.

Gemäß Anspruch 12 ist den Schneidvorrichtungen jeweils eine Abführvorrichtung zum Abführen des abgetrennten Bandes zugeordnet, welches in der Regel als Abfall entfernt wird.According to claim 12, the cutting devices are each assigned a discharge device for discharging the separated strip, which is usually removed as waste.

Zur Durchführung des Verfahrens sind verschiedene Bandwebrnaschinen geeignet, besonders vorteilhaft ist jedoch nach Anspruch 13 eine Nadelbandwebmaschine mit drei übereinander angeordneten Schusseintragnadeln.Various ribbon weaving machines are suitable for carrying out the method, however, a needle ribbon loom with three weft insertion needles arranged one above the other is particularly advantageous.

Das neuartige, doppelseitige Samtband, ermöglicht neue und verbesserte Anwendungen.The novel double-sided velvet tape allows new and improved applications.

Die Schussfäden 28, 30 und 32 werden mittels eines Webblattes 34 an den drei übereinander liegenden Webstellen 31 angeschlagen. Durch Verändern des gegenseitigen Abstandes der Führungsplatten 4, 6 mittels schematisch angedeuteter Stellvorrichtungen 33, 35 kann der gegenseitige Abstand der Bänder 8, 10 und 12 und damit die Höhe der Florfäden 14 eingestellt werden.The FIG. 1 shows a ribbon loom 2, in which between an upper guide plate 4 and a lower guide plate, a middle band 8, a lower band 10 and an upper band 12 are produced, which are connected to each other transverse to the belt plane pile threads 14. For this purpose, in a shedding device 16, the warp threads 18 are guided by means of strands 20 so that three sheds 22, 24 and 26 are formed, are entered into the respective weft threads 28, 30 and 32. The weft threads are suitably entered by means not shown weft needles a ribbon loom, the weft needles are arranged according to the supplied weft yarns 28, 30 and 32 one above the other and together are effective simultaneously. The weft threads 28, 30 and 32 are struck by means of a reed 34 at the three superimposed weaves 31. By changing the mutual distance of the guide plates 4, 6 by means of schematically indicated adjusting devices 33, 35, the mutual distance of the bands 8, 10 and 12 and thus the height of the pile threads 14 can be adjusted.

Den Webstellen 31 ist eine erste Schneidvorrichtung 36 nachgeordnet, die eine Führung 38 und ein Schneidorgan 40 aufweist, welches die Florfäden 14a zwischen dem mittleren Band 8 und dem oberen Band 12 durchtrennt. Das obere Band 12 wird mittels einer Abführvorrichtung 42, welche eine Nadelwalze 44 aufweist, als Abfall abgeführt. Der ersten Schneidvorrichtung 36 ist eine zweite, untere Schneidvorrichtung 46 nachgeschaltet, die ebenfalls eine Führung 48 und ein Schneidorgan 50 aufweist. Sie durchtrennt die Florfäden 14b zwischen dem mittleren Band 8 und dem unteren Band 10. Das untere Band 10 wird mittels einer Abführvorrichtung 52, die wiederum eine Nadelwalze 54 aufweist, als Abfall abgeführt. Das verbleibende mittlere Band 8 weist einen beidseitigen flor 56,58 auf und wird über eine Abführvorrichtung 60 abgeführt. Auch diese weist vorzugsweise eine Nadelwalze 62 auf, die mit Nadeln 64 zur gesicherten Anführung des hergestellten Samtbandes 8 besetzt ist.The weaves 31 are followed by a first cutting device 36, which has a guide 38 and a cutting member 40, which cuts through the pile threads 14a between the middle band 8 and the upper band 12. The upper belt 12 is discharged by means of a discharge device 42, which has a needle roller 44, as waste. The first cutting device 36 is followed by a second, lower cutting device 46, which also has a guide 48 and a cutting member 50. It cuts through the pile threads 14b between the middle band 8 and the lower band 10. The lower band 10 is discharged by means of a discharge device 52, which in turn has a needle roller 54, as waste. The remaining middle band 8 has a bilateral flor 56,58 and is discharged via a discharge device 60. This, too, preferably has a needle roller 62 which is occupied with needles 64 for secure guidance of the produced velvet ribbon 8.

Die Figuren 2 bis 4 zeigen eine weitere Bandwebmaschine, die prinzipiell entsprechend der ersten Bandwebmaschine der Figur 1 aufgebaut ist, so dass gleiche Teile mit gleichen Bezugszeichen versehen sind. Im Gegensatz zu der Bandwebmaschine der Figur 1 sind bei der Bandwebmaschine der Figuren 2 bis 4 die Schneidvorrichtungen 36a, 46a nicht unabhängig voneinander angeordnet, sondern nebeneinander und weisen ein gemeinsames Schneidorgan 66 auf, das als Messer ausgebildet ist und mittels eines Antriebes 68 hin- und hergehend angetrieben ist.The FIGS. 2 to 4 show another ribbon loom, which in principle corresponding to the first ribbon loom of FIG. 1 is constructed so that the same parts are provided with the same reference numerals. Unlike the ribbon loom of FIG. 1 are in the ribbon loom the FIGS. 2 to 4 the cutting devices 36a, 46a are not arranged independently of each other, but next to each other and have a common cutting member 66 which is formed as a knife and driven by a drive 68 back and forth.

Das von der Webstelle 31 kommende Dreifachband 8, 10, 12 wird nach einer ersten Führung 70 einer ersten Schneidvorrichtung 36a zugeführt, die zwei Führungsplatten 72, 74 aufweist. Die untere Führungsplatte 72 ist feststehend und die obere Führungsplatte 74 ist mittels einer angedeuteten Stellvorrichtung 76 im Abstand zur unteren Führungsplatte 72 einstellbar. An der ersten Schneidvorrichtung 36a wird das abgeschnittene untere Band 10 mittels einer Abführvorrichtung 42a und einer entsprechenden Nadelwalze 44a nach unten abgeführt.The triple belt 8, 10, 12 coming from the weaving area 31 is fed after a first guide 70 to a first cutting device 36a, which has two guide plates 72, 74. The lower guide plate 72 is fixed and the upper guide plate 74 is adjustable by means of an indicated adjusting device 76 at a distance from the lower guide plate 72. At the first cutter 36a, the cut lower belt 10 is discharged downwardly by means of a discharge device 42a and a corresponding needle roller 44a.

Das mittlere Band 8 mit dem darüber liegenden oberen Band 12 wird einer ersten als Nadelwalze ausgebildeten Umlenkwalze 78 seitlich versetzt zugeführt, die es nach rückwärts umlenkt und weiter seitlich versetzt über eine erste feststehende Führung 80 einer zweiten Richtführung 82 zuführt, an der es soweit umgelenkt wird, bis es parallel zum Dreifachband 8, 10, 12 ausrichtet ist. Über zwei weitere Umlenkwalzen 84, 86 wird es der zweiten Schneidvorrichtung 46a zuführt. Diese weist wiederum eine untere Führungsplatte 88 und eine obere Führungsplatte 90 auf, die mittels angedeuteter Stellvorrichtungen 92, 94 in der Höhenlage und/oder im gegenseitigen Abstand einstellbar sind. Insbesondere die untere Führungsplatte 88 der zweiten Schneidvorrichtung 46a muss gegenüber der Führungsplatte 72 der ersten Schneidvorrichtung auf solche Höhe eingestellt werden, dass das mittlere Band 8 beidseits die gleiche Florhöhe aufweist, da für beide Schneidvorrichtungen 36a,46a das gleiche Schneidorgan 66 verwendet, jedoch die Dicke der Bänder einschliesslich Florhöhe unterschiedlich sind. An der zweiten Schneidvorrichtung 46a wird das obere Band 12 vom mittleren Band 8 getrennt. Das obere Band 12 wird wiederum als Abfall über die Abführvorrichtung 52a mit der Nadelwalze 54a entfernt. Das mittlere Band 8 wird als doppelseitiges Samtband mit einem Flor 56, 58 auf beiden Seiten mittels einer Abführvorrichtung 60 abgeführt, welche wiederum eine Nadelwalze 62 enthält.The middle band 8 with the overlying upper band 12 is laterally offset supplied to a first formed as a needle roller guide roller 78, which deflects it backwards and further offset laterally via a first fixed guide 80 a second guide 82 feeds, where it is deflected so far until it is aligned parallel to the triple band 8, 10, 12. It is fed to the second cutting device 46a via two further deflection rollers 84, 86. This in turn has a lower guide plate 88 and an upper guide plate 90 which are adjustable by means of indicated adjusting devices 92, 94 in the vertical position and / or in the mutual distance. In particular, the lower guide plate 88 of the second cutter 46a has to be adjusted to the height of the guide plate 72 of the first cutter such that the middle tape 8 has the same pile height on both sides since the same cutter 66 is used for both cutters 36a, 46a. However, the thickness of the bands including pile height are different. At the second cutter 46a, the upper band 12 is separated from the middle band 8. The upper band 12 is again removed as waste via the discharge device 52a with the needle roller 54a. The middle band 8 is removed as a double-sided velvet belt with a pile 56, 58 on both sides by means of a discharge device 60, which in turn contains a needle roller 62.

Im vorliegenden Ausführungsbeispiel sind die Umlenkwalze 78 der Umlenkvorrichtung und die Nadelwalze 54a der Abführvorrichtung 52a einstückig ausgebildet.
