Abstract

The invention relates to a woven belt for a corrugated cardboard machine. The belt has a tensile stress-absorbing central woven layer (20) in which the warp threads (21, 22) run over at least two weft threads (4) and said layer (20) is covered by an upper layer (10) forming the paper side and a lower layer (30). In the upper layer (10) the warp threads (11, 12, 13, 14) run inwards and outwards over at least two weft threads (4) and in the lower layer (30) the warp threads (31, 32, 33, 34) run inwards over only one weft thread (4) and outwards over at least three weft threads (4). In the upper and lower layers (10, 30) the warp threads (11 to 14, 31 to 34) inside a group of threads are mutually staggered. All the layers (10, 20, 30) are woven together by binding threads (40, 41, 42, 43), whereby the weft threads (4) are tied off in the layers (10, 20, 30). In order to retain a uniform surface even after a longer operating time, there is at least one outer warp thread (11', 12', 13', 14') running along the belt (1) in the upper layer (10) at the edge region (7) of the belt (1) consisting of more wear and/or temperature-resistant material than the inner warp threads (11, 12, 13, 14) of the upper layer (10) between the edge regions (7) of the belt (1).

Description

Gewebter Gurt für eine Wellpappenmaschine Woven belt for a corrugated cardboard machine
Die Erfindung betrifft einen gewebten Gurt für eine Well¬ pappenmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a woven belt for a corrugated cardboard machine according to the preamble of claim 1.
Ein derartiger Gurt ist aus der DE 41 27 164 AI bekannt. Dieser Gurt weist eine große Laufruhe und somit einen deutlich geringeren Geräuschpegel am Einsatzort auf. Er zeigt eine hohe Standzeit, wobei sich mit wachsender Ein¬ satzzeit auf der der Papierseite zugewandten Gewebelage Oberflächenveränderungen ergeben haben, welche die Qualität der Wellpappenoberfläche beeinträchtigen können. Daher wird oft schon ein vorhandener Gurt aufgrund geringfügiger Ände¬ rung der Oberflächenqualität ausgetauscht, obwohl er auf¬ grund seines Aufbaus für eine noch längere Einsatzzeit ge¬ eignet wäre.Such a belt is known from DE 41 27 164 AI. This belt is very quiet and therefore has a significantly lower noise level at the place of use. It shows a long service life, with increasing usage time on the fabric layer facing the paper side surface changes have occurred which can impair the quality of the corrugated board surface. Therefore, an existing belt is often replaced due to a slight change in the surface quality, although its structure would make it suitable for an even longer period of use.
Der Erfindung liegt die Aufgabe zugrunde, einen Gurt für eine Wellpappenmaschine derart auszubilden, daß auch nach längerer Einsatzzeit eine gleichmäßig Oberflächenqualität der Wellpappe gewährleistet ist.The invention is based on the object of designing a belt for a corrugated cardboard machine in such a way that a uniform surface quality of the corrugated cardboard is ensured even after a long period of use.
Diese Aufgabe wird nach den Merkmalen des Anspruchs 1 ge¬ löst.This object is achieved according to the features of claim 1.
Es hat sich überraschend gezeigt, daß ein Gurt mit so ge¬ stärkten Längsrändern auch nach langer Binsatzzeit eine gleichbleibende hohe Oberflächenqualität der Wellpappe ge- währleistet. Diese Oberflächenqualität nimmt erst dann signifikant ab, wenn auch der Wellpappengurt an sich ver¬ schlissen ist und gegen einen neuen Gurt ausgetauscht wer¬ den muß. Die erfindungsgemäße Ausbildung gewährleistet so eine noch längere Einsatzzeit des Gurtes bei unverminderter Oberflächenqualität der Papierseite des Gurtes.It has surprisingly been found that a belt with such reinforced longitudinal edges has a consistently high surface quality of the corrugated cardboard even after a long period of use. ensures. This surface quality only decreases significantly when the corrugated cardboard belt itself is worn out and has to be exchanged for a new belt. The design according to the invention thus ensures an even longer period of use of the belt with an undiminished surface quality of the paper side of the belt.
Bevorzugt ist der unmittelbar der Längskante benachbart liegende Kettfaden aus verschleißfesterem und/oder tempera¬ turfesterem Material vorgesehen. Zweckmäßig sind mehrere benachbart zur Längsachse des Gurtes liegende, äußere Kett¬ fäden angeordnet, die aus einem verschleißfesteren oder temperaturfesteren Material bestehen, als die zwischen den Randbereichen des Gurtes angeordneten anderen Kettfäden der oberen Gewebelage.Preferably, the warp thread lying directly adjacent to the longitudinal edge is made of wear-resistant and / or temperature-resistant material. Advantageously, a plurality of outer warp threads lying adjacent to the longitudinal axis of the belt are arranged, which consist of a more wear-resistant or temperature-resistant material than the other warp threads of the upper fabric layer arranged between the edge regions of the belt.
Bevorzugt besteht der im Randbereich angeordnete äußere Kettfaden aus einem aromatischen Polyamid (Aramid)- Für hö¬ here Belastungen kann ein äußerer Kettfaden aus Kevlar ge¬ wählt sein; zur Erzielung eines erhöhten Abriebschutzes können dem Material des äußeren Kettfadens Metallfasern beigemischt sein. Dabei hat sich eine Zusammensetzung der Mischung - bezogen auf deren Gewicht - aus etwa 96,5% Po¬ lyamid und 3,5% nichtrostende Stahlfaser als vorteilhaft erwiesen.The outer warp thread arranged in the edge area preferably consists of an aromatic polyamide (aramid). For higher loads, an outer warp thread made of Kevlar can be selected; To achieve increased protection against abrasion, metal fibers can be added to the material of the outer warp thread. A composition of the mixture, based on its weight, of approximately 96.5% polyamide and 3.5% stainless steel fiber has proven to be advantageous.
Außer den äußeren Kettfäden der oberen Gewebelage ist der übrige Gurt in der oberen und den weiteren Gewebelagen aus Kunststoffäden bevorzugt gleichen Materials wie einer Mi¬ schung aus etwa 65% Polyester und etwa 35% Viskose (Zellwolle) gewebt.In addition to the outer warp threads of the upper fabric layer, the remaining belt in the upper and the further fabric layers is preferably made of plastic threads of the same material as a mixture of about 65% polyester and about 35% viscose (wool).
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und ist im folgenden eingehend er¬ läutert. Es zeigen:An embodiment of the invention is shown in the drawings and is explained in detail below. Show it:
Fig. 1 einen gewebten Gurt im Längsschnitt, Fig. 2 eine Teildraufsicht auf die obere, der Papierseite zugewandte Gewebelage,1 is a woven belt in longitudinal section, 2 is a partial plan view of the upper fabric layer facing the paper side,
Fig. 3 eine Draufsicht auf die Außenseite der unteren Ge¬ webelage des Gurtes,3 shows a plan view of the outside of the lower fabric layer of the belt,
Fig. 4 eine schematische Draufsicht auf einen Gewebegurt gemäß Fig. 1.4 shows a schematic top view of a fabric belt according to FIG. 1.
Der bevorzugt aus Kunststoffäden hergestellte Gurt besteht - wie Fig. 1 zeigt - aus einer oberen Gewebelage 10, einer mittleren Gewebelage 20 und einer unteren Gewebelage 30. Die der mittleren Gewebelage 20 abgewandte Seite der oberen Gewebelage 10 bildet die der Wellpappe zugewandte Papier¬ seite des Gewebegurtes 1.The belt, which is preferably made of plastic threads, consists - as shown in FIG. 1 - of an upper fabric layer 10, a middle fabric layer 20 and a lower fabric layer 30. The side of the upper fabric layer 10 facing away from the middle fabric layer 20 forms the paper side of the corrugated cardboard Fabric belt 1.
In den Gewebelagen 10, 20, 30 verlaufen die Schußfäden 4 quer zur Längsri .tung 5 (Fig. 2) des Gurtes 1.In the fabric layers 10, 20, 30, the weft threads 4 run transversely to the longitudinal direction 5 (FIG. 2) of the belt 1.
In der oberen Gewebelage 10 sind vier gegeneinander ver¬ setzt verlaufende Kettfäden 11, 12, 13, 14 (Fig. 1, 2) vor¬ gesehen, die sowohl nach innen zur mittleren Gewebelage 20 hin als auch nach außen zur Papierseite hin über jeweils mindestens zwei Schußfäden 4 laufen.In the upper fabric layer 10 there are four warp threads 11, 12, 13, 14 (FIGS. 1, 2) which are offset with respect to one another and which extend inwards towards the middle fabric layer 20 as well as outwards towards the paper side in each case at least two wefts 4 run.
Die mittlere Gewebelage 20 weist zwei zueinander versetzt verlaufende Kettfäden 21, 22 auf, die über jeweils zwei Schußfäden 4 laufen.The middle fabric layer 20 has two warp threads 21, 22 which are offset with respect to one another and each run over two weft threads 4.
Die untere Gewebelage 3 besteht aus vier jeweils versetzt zueinander laufenden Kettfäden 31, 32, 33, 34, die nach innen - zur mittleren Gewebelage 20 - über nur einen Schu߬ faden 4 und nach außen über zumindest drei Schußfäden 4 laufen. Die drei Gewebelagen 10, 20, 30 sind über Bindefäden 40, 41, 42, 43 miteinander verwebt. Die Bindefäden sind in je¬ weils zwei Fadengruppen unterteilt, wobei die eine Faden¬ gruppe bildenden Bindefäden 42, 43 zueinander versetzt lau¬ fen und die obere Gewebelage 10 an die mittlere Gewebelage 20 binden. Die Bindefäden 42 und 43 sind jeweils abwechselnd um einen Schußfaden 4 in der oberen Gewebelage 10 und einen Schußfaden 4 in der mittleren Gewebelage 20 geführt. In entsprechender Weise bindet die aus den Binde¬ fäden 40 und 41 bildende Fadengruppe die untere Gewebelage 30 an die mittlere Gewebelage 20.The lower fabric layer 3 consists of four warp threads 31, 32, 33, 34, each running offset to one another, which run inwards - to the middle fabric layer 20 - via only one weft thread 4 and outwards via at least three weft threads 4. The three fabric layers 10, 20, 30 are woven together by means of binding threads 40, 41, 42, 43. The binding threads are each divided into two thread groups, the binding threads 42, 43 forming a thread group running offset from one another and binding the upper fabric layer 10 to the middle fabric layer 20. The binding threads 42 and 43 are alternately guided around a weft thread 4 in the upper fabric layer 10 and a weft thread 4 in the middle fabric layer 20. In a corresponding manner, the group of threads forming the binding threads 40 and 41 binds the lower fabric layer 30 to the middle fabric layer 20.
Wie sich aus Fig. 4 in Verbindung mit Fig. 2 ergibt, ist im Randbereich 7 des Gurtes 1 in dessen oberer Gewebelage 10 mindestens ein äußerer, in Längsrichtung 5 des Gurtes 1 verlaufender Kettfaden 11', 12', 13', 14' angeordnet, der aus einem verschleißfesteren und/oder temperaturfesteren Material besteht als die zwischen den Randbereichen 7 des Gurtes 1 über den Zwischenraum Z angeordneten inneren Kett¬ fäden 11, 12, 13, 14 der oberen Gewebelage 1. Ein äußerer Kettfaden 13' aus verschleißfesterem und/oder temperaturfe¬ sterem Material liegt unmittelbar benachbart zur Längskante 2 (Fig. 4) des Gurtes 1. Bevorzugt sind eine Vielzahl be¬ nachbart zur Längskante 2 liegender, äußerer Kettfäden 11', 12', 13', 14' aus einem verschleißfesterem und/oder tempe¬ raturfesterem Material vorgesehen. Dabei können die Kettfä¬ den 11', 12', 13', 14' aus verschleißfesterem und/oder tem¬ peraturfesterem Material eine Fadengruppe bilden, wobei die Bindefäden 42 und 43 zwischen dieser und einer nächsten Fa¬ dengruppe von Kettfäden 11', 12', 13', 14' aus einem ver¬ schleißfesterem und/oder temperaturfesteren Material lie¬ gen. Bevorzugt sind auch die im Randbereich 7 in Längsrich¬ tung 5 des Gurtes 1 verlaufenden Bindefäden 42 und 43 aus einem verschleißfesteren und/oder temperaturfesteren Mate¬ rial vorgesehen. Um über eine lange Betriebszeit des Gurtes über dessen ge¬ samte Breite eine weitgehend gleichmäßige Oberflächenquali¬ tät zu gewährleisten, sind alle in einem Randbereich 7 verlaufenden Längsfäden 11', 12', 13', 14', 42, 43 aus einem temperaturfesteren bzw. verschleißfesteren Material ausgebildet. Der Randbereich 7 hat bevorzugt eine Breite R von etwa 200 mm.As can be seen from FIG. 4 in conjunction with FIG. 2, at least one outer warp thread 11 ′, 12 ′, 13 ′, 14 ′, which runs in the longitudinal direction 5 of the belt 1, is arranged in the edge region 7 of the belt 1 in its upper fabric layer 10 , which consists of a more wear-resistant and / or temperature-resistant material than the inner warp threads 11, 12, 13, 14 of the upper fabric layer 1 arranged between the edge regions 7 of the belt 1 via the intermediate space Z. An outer warp thread 13 'made of wear-resistant and / or temperature-resistant material lies directly adjacent to the longitudinal edge 2 (FIG. 4) of the belt 1. A plurality of outer warp threads 11 ', 12', 13 ', 14' lying adjacent to the longitudinal edge 2 are preferably made of a more wear-resistant and / or more temperature-resistant material is provided. The warp threads 11 ', 12', 13 ', 14' made of more wear-resistant and / or temperature-resistant material can form a thread group, the binding threads 42 and 43 between this and a next thread group of warp threads 11 ', 12 ', 13', 14 'made of a more wear-resistant and / or temperature-resistant material. Also preferred are the binding threads 42 and 43 made in the edge region 7 in the longitudinal direction 5 of the belt 1 and made of a more wear-resistant and / or temperature-resistant material rial provided. In order to ensure a largely uniform surface quality over a long operating time of the belt over its entire width, all longitudinal threads 11 ', 12', 13 ', 14', 42, 43 running in an edge region 7 are made of a temperature-resistant or more wear-resistant material. The edge region 7 preferably has a width R of approximately 200 mm.
Als verschleißfesteres bzw. temperaturfesteres Material hat sich aromatisches Polyamid gezeigt, welches auch als Aramid bezeichnet wird. Aus der Gruppe der Polyamide ist insbeson¬ dere Kevlar besonders geeignet, bei dessen Verwendung ein hoch belastbarer Gurt erzielt ist. Auch wenn die genannten Polyamide bereits eine gute Abriebfestigkeit und Tempera¬ turbeständigkeit zeigen, kann durch Beimischung von Metall¬ fasern eine weitere Steigerung der Standzeit bei gleichmäßiger Oberflächenqualität erreicht werden. Neben dem erhöhten Abriebschutz ist durch die Metallfasern eine erhöhte thermische Leitfähigkeit gegeben, wodurch der Kitzetransfer verbessert ist. Als Metallfasern sind bevorzugt nichtrostende Metallfasern', zweckmäßig nichtrostende Stahlfasern eingesetzt, die in einer Menge von bis etwa 3,5 Gewichtsprozenten dem Grundmaterial aromatisches Polyamid (96,5 Gewichtsprozente) beigemischt werden können.Aromatic polyamide, which is also referred to as aramide, has been shown to be a more wear-resistant or temperature-resistant material. From the group of polyamides, Kevlar is particularly suitable, and when used, a highly resilient belt is achieved. Even if the polyamides mentioned already have good abrasion resistance and temperature resistance, a further increase in the service life with a uniform surface quality can be achieved by adding metal fibers. In addition to the increased protection against abrasion, the metal fibers provide increased thermal conductivity, which improves the fawn transfer. The metal fibers preferably stainless metal fibers ", advantageously stainless steel fibers are used, the (96.5 weight percent) can be blended in an amount of up to about 3.5 percent by weight of the base material aromatic polyamide.
Die übrigen Fäden des Gewebegurtes der oberen, mittleren und unteren Gewebelage beε shen aus Kunststoff bzw. einem Material aus etwa 65% Polyester und 35% Viskose (Zellwolle). The remaining threads of the fabric belt of the upper, middle and lower fabric layer are made of plastic or a material made of about 65% polyester and 35% viscose (rayon).
