Description

Die Erfindung betrifft einen Gewebegurt zur Herstellung einer Wellpappenbahn in einer Wellpappenmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a fabric belt for producing a corrugated cardboard web in a corrugator machine according to the preamble of claim 1.

Die Verbindung eines Gewebegurtes zu einem Endlosgurt ist aus der DE 195 40 229 C1 bekannt. Die Gurtenden werden in der Dicke reduziert und zum Verbinden eine Vielzahl von mit Abstand nebeneinander liegenden Klammern eingepresst. Die Klammern des einen Gurtendes liegen versetzt zu den Klammern des anderen Gurtendes. Werden die Klammern des einen Endes in die Klammern des anderen Endes ineinandergeschoben und ein alle Klammern gemeinsam durchragender Verbindungsstab eingesetzt, ist ein bewegliches Gelenk gebildet, welches einen störungsfreien Umlauf des Gurtes an Umlenkrollen, Antriebswalzen oder dgl. gewährleistet.The connection of a fabric belt to an endless belt is from the DE 195 40 229 C1 known. The strap ends are reduced in thickness and for connecting a plurality of spaced adjacent clips pressed. The clips of one strap end are offset from the clips of the other strap end. If the clamps of one end are pushed into each other in the clamps of the other end and a connecting rod penetrates all the clamps together, a movable joint is formed, which ensures a trouble-free circulation of the belt on pulleys, drive rollers or the like.

Der Gewebegurt unterliegt insbesondere auf der Antriebsseite einem erhöhten Verschleiß durch den Antrieb. Die Verbindung der Gurtenden muss dabei so geschaffen sein, dass die Klammern nicht mit den Antriebswalzen in Verbindung kommen. Dies kann zu einer Zerstörung der Verbindung und damit zum Reißen des Endlosgurtes führen.The fabric belt is subject to increased wear by the drive, in particular on the drive side. The connection of the strap ends must be created so that the brackets do not come into contact with the drive rollers. This can lead to a destruction of the connection and thus to the tearing of the endless belt.

Aus der WO 02/086232 A1 ist bekannt, die dickenreduzierten Gurtenden mit einem Flockmaterial zu beschichten, um die durch die Dickenreduzierung gebildete Vertiefung im Gurt zu egalisieren. Ein derartiger Gurt hat sich in der Praxis bewährt; die Standzeit ist aber weiterhin durch den Verschleiß auf der Antriebsseite bestimmt. Ist das Flockmaterial abgetragen, können die Klammern der Verbindung verschleißen, was zu einer Zerstörung des Gurtes führt.From the WO 02/086232 A1 It is known to coat the reduced thickness belt ends with a flock material to equalize the depression formed in the belt by the thickness reduction. Such a belt has proven itself in practice; the service life is still determined by the wear on the drive side. Once the flock material has worn away, the brackets of the joint may wear, resulting in the destruction of the belt.

Der Erfindung liegt die Aufgabe zugrunde, einen Gewebegurt zur Herstellung einer Wellpappenbahn in einer Wellpappenmaschine derart auszubilden, dass seine Einsatzzeit erhöht ist.The invention has the object of providing a fabric belt for producing a corrugated cardboard web in a corrugator in such a way that its service life is increased.

Die Aufgabe wird erfindungsgemäß nach den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved according to the characterizing features of claim 1.

Nach dem Kerngedanken der Erfindung ist der Abstand der der ersten Gurtseite zugewandt liegenden Ebene des dickenreduzierten Gurtendes mit den eingepressten Klammern zur Ebene dieser ersten Gurtseite größer als der der zweiten anderen Gurtseite zugewandt liegende Abstand der Ebene des dickenreduzierten Gurtendes mit den eingepressten Klammern zu der zweiten, anderen Gurtseite. Dabei ist die erste Gurtseite die verschleißstarke Gurtseite, auf der die Abpressung der Gurtenden stärker ausgebildet ist als auf der verschleißärmeren, zweiten Gurtseite. Dadurch wird auf der verschleißstärkeren Gurtseite dem Verschleiß mehr Material zur Verfügung gestellt, bevor die Klammern der Verbindungsstelle der Gurtenden freigelegt sind und ebenfalls verschleißen. Aufgrund der stärkeren Dickenreduzierung auf der verschleißstarken Gurtseite kann somit die Standzeit des Endlosgurtes in einfacher Weise erhöht werden.According to the essence of the invention, the distance of the first side facing the belt side of the reduced thickness belt end with the pressed-in clamps to the plane of this first belt side is greater than the second other belt side facing the distance of the plane of the reduced thickness belt end with the pressed-in brackets to the second, other strap side. In this case, the first side of the belt is the wear-resistant side of the belt on which the pressing of the belt ends is made stronger than on the second side of the belt with less wear. As a result, more material is made available to wear on the more wear-resistant belt side, before the clamps of the junction of the strap ends are exposed and also wear out. Due to the greater thickness reduction on the wear-resistant belt side, the service life of the endless belt can thus be increased in a simple manner.

Um in einfacher Weise eine Dickenreduzierung durch beheizte Pressplatten zu erzielen und gleichzeitig auf der verschleißstärkeren Gurtseite eine stärkere Dickenreduzierung zu erreichen ist das Gewebe des Gurtes auf der ersten, verschleißstärkeren Gurtseite vorteilhaft lockerer ausgebildet als das Gewebe auf der zweiten Gurtseite. Das lockerere Gewebe kann stärker zusammengepresst werden, wodurch sich die stärkere Dickenreduzierung auf der Verschleißseite ergibt.In order to achieve a reduction in thickness by heated pressure plates in a simple manner and at the same time to achieve a greater reduction in thickness on the wear-prone side of the belt, the fabric of the belt on the first, wear-prone side of the belt is advantageously looser than the fabric on the second side of the belt. The looser fabric can be compressed more strongly, resulting in the greater reduction in thickness on the wear side.

Es kann auch zweckmäßig sein, zumindest einen Teil der Fäden des Gewebes auf der verschleißstärkeren Gurtseite mit einem Material mit niedrigerem Schmelzpunkt auszuführen als die anderen Fäden des Gewebes auf der gleichen Seite oder die anderen Fäden des Gurtes selbst. Aufgrund des niedrigeren Schmelzpunktes wird die auf der verschleißstarken Gurtseite wirkende Druckplatte stärker in das Gewebe einsinken als auf der gegenüberliegenden anderen Gurtseite. Dabei kann es zweckmäßig sein, das Gewebe auf der ersten, verschleißstarken Gurtseite vollständig aus Fäden zu bilden, die einen niedrigeren Schmelzpunkt haben als die Fäden des Gewebes auf der anderen, zweiten Gurtseite.It may also be expedient to carry out at least a portion of the threads of the fabric on the wear-prone side of the belt with a material of lower melting point than the other threads of the fabric on the same side or the other threads of the belt itself. Due to the lower melting point is on the Wear-resistant belt-side pressure plate sink deeper into the tissue than on the opposite other side of the belt. It may be expedient to form the fabric on the first, wear-prone belt side completely of threads that have a lower melting point than the threads of the fabric on the other, the second side of the belt.

Ein vorteilhaftes Maß des Abstandes auf der verschleißstärkeren Gurtseite ist erzielt, wenn der Abstand zwischen der Ebene der dickenreduzierten Gurtenden und der Ebene der verschleißstärkeren Gurtseite um das 0,4fache bis 4fache größer ist als der Abstand der Ebene der dickenreduzierten Gurtenden zur Ebene der anderen, verschleißärmeren Gurtseite. Als vorteilhaft hat sich ein Wert erwiesen, wonach der Abstand auf der verschleißstarken Gurtseite etwa doppelt so groß ist wie der Abstand auf der verschleißarmen Seite.An advantageous measure of the distance on the wear-resistant belt side is achieved when the distance between the Level of the reduced thickness belt ends and the level of wear-prone belt side by 0.4 times to 4 times greater than the distance of the plane of the reduced thickness belt ends to the plane of the other, wear-poor belt side. A value has proven to be advantageous, according to which the distance on the wear-resistant belt side is approximately twice as great as the distance on the low-wear side.

Sollen Änderungen am Gewebe des Gewebegurtes, der Gewebestruktur und der verwendeten Gewebefäden vermieden werden, kann die Dickenreduzierung dadurch erreicht werden, dass diese auf der verschleißstarken Seite mit einer höheren Temperatur ausgeführt wird als auf der verschleißarmen Seite.If changes to the fabric of the fabric belt, the fabric structure and the fabric threads used are to be avoided, the thickness reduction can be achieved by carrying it out on the high-wear side at a higher temperature than on the low-wear side.

Ein zweckmäßiges Material für die Fäden mit niedrigerem Schmelzpunkt ist Polypropylen; die anderen, einen höheren Schmelzpunkt aufweisenden Fäden bestehen bevorzugt aus Polyester. Dabei kann es zweckmäßig sein, das Material mit einem niedrigeren Schmelzpunkt als Beschichtung auf einem Faden aus Material mit einem höheren Schmelzpunkt aufzubringen.A convenient material for the lower melting point yarns is polypropylene; the other, higher melting point filaments are preferably made of polyester. It may be appropriate to apply the material with a lower melting point than coating on a thread of material with a higher melting point.

Bei einem Gewebegurt zur Herstellung einer Wellpappenbahn in einer Wellpappenmaschine ist die verschleißstarke, erste Gurtseite die Antriebsseite und die zweite, verschleißarme Gurtseite die Papierseite.In a fabric belt for producing a corrugated cardboard web in a corrugator machine, the wear-resistant, first belt side is the drive side and the second, low-wear belt side is the paper side.

In entsprechender Weise bindet die aus den Bindefäden 40 und 41 bestehende Fadengruppe die untere Gewebelage 30 an die mittlere Gewebelage 20.The three fabric layers 10, 20 and 30 are connected to each other via binding threads 40, 41, 42 and 43. The binding threads are subdivided into two groups of threads, wherein the binding threads 42 and 43 forming a thread group run offset to one another and bind the upper fabric layer 10 to the middle fabric layer 20. The binding threads 42 and 43 are each alternately via a weft thread 4 in the upper fabric layer 10 and a Weft 4 out in the middle fabric layer 20. In a corresponding manner, the thread group consisting of the binding threads 40 and 41 binds the lower fabric layer 30 to the middle fabric layer 20.

Die Fäden des gezeigten Gewebegurtes 1 bestehen aus Polyester oder anderen geeigneten Trägerfasern wie Baumwolle. Zweckmäßig kann das Gewebe einen Anteil von mehr als 30% Fasern aus aromatischem Polyamid aufweisen. In bevorzugter Ausgestaltung besteht der Gewebegurt 1 aus mehr als 90% Paraaramid- (Kevlar) Fäden mit einem ergänzenden Anteil aus Polyesterfäden oder anderen Trägerfasern.The threads of the fabric belt 1 shown are made of polyester or other suitable carrier fibers such as cotton. Conveniently, the fabric may comprise more than 30% aromatic polyamide fibers. In a preferred embodiment, the fabric strap 1 consists of more than 90% para-aramid (Kevlar) threads with a supplementary portion of polyester threads or other carrier fibers.

Die Gewebestruktur des Gurtes 1 ist aufgrund des Materials der verwendeten Fäden durch Hitzeeinwirkung verformbar. Zum Verbinden der Gurtenden 2 und 3 werden diese von der Ausgangsdicke d der Gewebestruktur des Gurtes 1 in der Höhe reduziert. Bei einer Ausgangsdicke von etwa 7 mm bis 11 mm, vorzugsweise etwa 5 mm bis 10 mm wird die Dicke um ein Maß u, v von etwa 1 mm bis 2 mm, vorzugsweise 1,25 mm bis 1,75 mm in der Dicke reduziert. Hierzu hat es sich als zweckmäßig erwiesen, die Enden 2, 3 des Gewebegurtes 1 zwischen zwei vorzugsweise beheizten Druckplatten 50, 51 zu behandeln, wobei die Dickenreduzierung unter erhöhter Temperatur und Druck erfolgt.The fabric structure of the belt 1 is deformable due to the material of the threads used by the action of heat. To connect the belt ends 2 and 3, these are reduced in height by the initial thickness d of the fabric structure of the belt 1. With a starting thickness of about 7 mm to 11 mm, preferably about 5 mm to 10 mm, the thickness is reduced by a dimension u, v of about 1 mm to 2 mm, preferably 1.25 mm to 1.75 mm in thickness. For this purpose, it has proven expedient to treat the ends 2, 3 of the fabric belt 1 between two preferably heated pressure plates 50, 51, wherein the thickness reduction takes place under elevated temperature and pressure.

In die dickenreduzierten Gurtenden 2, 3 werden Klammern 7 eingepresst, wie es in Fig. 1 dargestellt ist. Das Einpressen der Klammern 7 erfolgt unter Druck und Temperatur, wobei es sich als zweckmäßig erwiesen hat, die Klammern unter einer höheren Temperatur und einem höheren Druck einzupressen als die bei der Dickenreduzierung angewandte Temperatur und der Druck. Vorteilhaft werden eine Temperatur von etwa 180° und ein Druck von etwa 590 bar aufgebracht, um die Klammern einzupressen. Es kann vorteilhaft sein, die Dickenreduzierung und das Einpressen der Klammern gleichzeitig auszuführen.Clamps 7 are pressed into the thickness-reduced strap ends 2, 3, as shown in FIG Fig. 1 is shown. The pressing of the clamps 7 is carried out under pressure and temperature, wherein it has proven expedient to press the clamps at a higher temperature and a higher pressure than those at Thickness reduction applied temperature and pressure. Advantageously, a temperature of about 180 ° and a pressure of about 590 bar applied to press the brackets. It may be advantageous to carry out the reduction in thickness and the pressing in of the staples at the same time.

Die zum Verbinden der dickenreduzierten Gurtenden 2, 3 verwendeten Klammern 7 sind vor ihrer Einbaulage gemäß Fig. 1 entsprechend der Darstellung in Fig. 2 vorgebogen. Jede Klammer 7 besteht im Wesentlichen aus einem halbkreisförmig gebogenen Kopf 17, der mit zwei Schenkeln 15, 16 die Form eines zu einer Mittelebene 25 etwa symmetrischen U bildet. Der eine Schenkel 16 ist dabei länger als der andere Schenkel 15 ausgebildet, wobei ihre freien Endabschnitte 18 nach innen widerhakenartig abgewinkelt liegen. Die widerhakenartig in die Gurtenden 2, 3 eingreifenden Endabschnitte 18 der geschlossenen Klammer 7 sind fest in das dickenreduzierte Gewebe der Gurtenden 2, 3 eingepresst, so dass sie sich auch bei großer mechanischer Belastung in Gurtlängsrichtung nicht aus den Gurtenden lösen.The brackets 7 used for connecting the thickness-reduced belt ends 2, 3 are according to their installation position Fig. 1 as shown in Fig. 2 pre-bent. Each bracket 7 consists essentially of a semicircular curved head 17, which forms the shape of a central plane 25 approximately symmetrical U with two legs 15, 16. The one leg 16 is designed to be longer than the other leg 15, wherein their free end portions 18 are angled barbs inwardly. The barb-like in the strap ends 2, 3 engaging end portions 18 of the closed bracket 7 are firmly pressed into the reduced thickness tissue of the strap ends 2, 3, so that they do not come off the strap ends even with great mechanical stress in the belt longitudinal direction.

Wie Fig. 3 zeigt, wird über die Breite G des Gurtes 1 in jedem Gurtende eine Vielzahl von Klammern 7 angeordnet, die mit gleichem Abstand a zueinander liegen. Zur Erzielung einer hohen Festigkeit der Verbindung wird ein Abstand a von etwa 1,8 mm bis etwa 4 mm gewählt.As Fig. 3 shows, across the width G of the belt 1 in each end of the belt, a plurality of brackets 7 are arranged, which are at the same distance a to each other. To achieve a high strength of the connection, a distance a of about 1.8 mm to about 4 mm is selected.

Wie sich ferner aus Fig. 3 ergibt, werden die Klammern 7 derart angeordnet, dass nebeneinander liegende Klammern jeweils um 180° gedreht liegen. Somit liegt einmal der kürzere Schenkel 15 und einmal der längere Schenkel 16 auf einer Seite. Die Längen der Schenkel 15 und 16 der Klammer 7 liegen etwa zwischen 16 mm und 26 mm.As further out Fig. 3 results, the brackets 7 are arranged such that adjacent brackets are each rotated by 180 °. Thus, once lies the shorter one Leg 15 and once the longer leg 16 on one side. The lengths of the legs 15 and 16 of the bracket 7 are approximately between 16 mm and 26 mm.

Wie Fig. 1 zeigt, liegen die Klammern 7 des einen Gurtendes 2 in den Lücken zwischen den Klammern 7 des anderen Gurtendes 3. Auf diese Weise können die Gurtenden 2, 3 derart aneinander angenähert werden, dass durch alle Klammern 7 beider Gurtenden 2, 3 ein Verbindungsstab 9 gesteckt werden kann, der zusammen mit den Klammern 7 ein bewegliches Gelenk an der Nahtstelle des Endlosgurtes bildet. Der Verbindungsstab hat einen zylindrischen Querschnitt und etwa einen Durchmesser von vorzugsweise 2 mm bis 4 mm.As Fig. 1 shows, the brackets 7 of one strap end 2 in the gaps between the brackets 7 of the other strap end 3. In this way, the strap ends 2, 3 can be approximated to each other that through all the brackets 7 both strap ends 2, 3, a connecting rod 9 inserted can be, which together with the brackets 7 forms a movable joint at the seam of the endless belt. The connecting rod has a cylindrical cross-section and approximately a diameter of preferably 2 mm to 4 mm.

Um nach Einbringen der Klammerung eine Egalisierung der Gurtfläche zu erzielen, kann ein Flockmaterial aufgebracht werden, das den Raum zwischen den dickenreduzierten Enden und der Papierseite 6 bzw. der Antriebsseite 8 füllt.In order to achieve a leveling of the belt surface after the introduction of the stapling, a flock material can be applied which fills the space between the thickness-reduced ends and the paper side 6 or the drive side 8.

Zur Erzielung einer höheren Standzeit des Gurtes 1 ist vorgesehen, auf der Antriebsseite 8 des Gewebegurtes 1 eine Dickenreduzierung um ein Maß u vorzusehen, das deutlich größer als das Maß v der Dickenreduzierung auf der Papierseite 6 ist. Es ist zweckmäßig, den Abstand u zwischen der Ebene 36 des der Antriebsseite 8 zugewandten Gurtendes 2, 3 zur Ebene 37 der Abtriebsseite 8 um das 0,4fache bis 4fache größer zu wählen als der Abstand v, den die der Papierseite 6 zugewandte Ebene 46 der dickenreduzierten Gurtenden 2, 3 zur Ebene 47 der Papierseite 6 aufweist. In besonderer Ausgestaltung ist der Abstand u etwa doppelt so groß wie der Abstand v.To achieve a longer service life of the belt 1 is provided to provide on the drive side 8 of the fabric belt 1 a thickness reduction by a measure u, which is significantly larger than the dimension v of the thickness reduction on the paper side 6. It is expedient to choose the distance u between the plane 36 of the drive side 8 facing belt end 2, 3 to the level 37 of the output side 8 by 0.4 times to 4 times greater than the distance v, the paper side 6 facing the plane 46 of having reduced thickness strap ends 2, 3 to the plane 47 of the paper page 6. In a particular embodiment, the distance u is about twice as large as the distance v.

Um auf der Antriebsseite 8 eine größere Dickenreduzierung zu erreichen als auf der Papierseite 6, ist vorgesehen, die Druckplatte 51 auf der Antriebsseite des Gurtes auf eine höhere Temperatur aufzuheizen als die Druckplatte 50 auf der Papierseite 6 des Gewebegurtes. Der Anpressdruck beim Zusammenfahren der Druckplatten 50 und 51 ist auf beiden Gurtseiten 6, 8 gleich, so dass lediglich aufgrund der höheren Temperatur der Druckplatte 51 im gleichen Zeitraum auf der Antriebsseite 8 mehr Material geschmolzen und verdichtet werden kann als auf der Papierseite 6.In order to achieve a greater reduction in thickness on the drive side 8 than on the paper side 6, it is provided to heat the pressure plate 51 on the drive side of the belt to a higher temperature than the pressure plate 50 on the paper side 6 of the fabric belt. The contact pressure during the collapse of the pressure plates 50 and 51 is the same on both sides of the belt 6, 8, so that only due to the higher temperature of the pressure plate 51 in the same period on the drive side 8 more material can be melted and compacted than on the paper side. 6

Um bei gleicher Temperatur der Druckplatten 50 und 51 und gleichem Druck auf der Abtriebsseite 8 ein größeres Maß u an Dickenreduzierung zu erhalten, ist in einem weiteren Ausführungsbeispiel der Erfindung vorgesehen, das Gewebe des Gurtes 1 auf der Antriebsseite 8 lockerer auszubilden als das Gewebe des Gurtes 1 auf der Papierseite 6. Dies kann dadurch erreicht werden, dass auf der Antriebsseite z. B. ein Kettfaden 31, 32, 33, 34 weniger verarbeitet wird als auf der Papierseite. Aufgrund des dann lockereren Gewebes auf der Antriebsseite 8 wird die Druckplatte 51 bei gleicher Temperatur im gleichen Zeitraum tiefer in den Gewebegurt einsinken als die Druckplatte 50 auf der Papierseite 6, so dass ein größeres Maß u an Dickenreduzierung auf der Antriebsseite 8 erzielt ist.In order to obtain a greater degree u of thickness reduction at the same temperature of the pressure plates 50 and 51 and the same pressure on the output side 8, it is provided in a further embodiment of the invention, the fabric of the belt 1 on the drive side 8 looser form than the fabric of the belt 1 on the paper side 6. This can be achieved in that on the drive side z. B. a warp thread 31, 32, 33, 34 is less processed than on the paper side. Due to the then looser tissue on the drive side 8, the pressure plate 51 at the same temperature in the same period deeper into the fabric belt sink than the pressure plate 50 on the paper side 6, so that a greater degree u reduction in thickness on the drive side 8 is achieved.

Soll das Gewebe auf der Papierseite 6 wie auf der Antriebsseite 8 mit gleicher Stärke ausgebildet werden, kann eine unterschiedliche Dickenreduzierung dadurch erreicht werden, dass auf der Antriebsseite 8 zumindest ein Teil der Fäden des Gewebes einen niedrigeren Schmelzpunkt aufweisen, als die anderen Fäden des Gewebes auf der Papierseite 6. Der niedrigere Schmelzpunkt einiger auf der Antriebsseite 8 verarbeiteter Gewebefäden führt ebenfalls dazu, dass bei gleicher Temperatur der Druckplatten 50, 51 die Druckplatte 51 auf der Antriebsseite 8 tiefer in die Gewebestruktur einsinkt als auf der Papierseite. Es kann zweckmäßig sein, die Fäden der Antriebsseite 8 vollständig aus einem Material vorzusehen, das einen niedrigeren Schmelzpunkt hat als das Material der Fäden auf der Papierseite 6 des Gewebegurtes 1.If the tissue on the paper side 6 is to be formed with the same thickness as on the drive side 8, a different thickness reduction can be achieved by on the drive side 8, at least some of the threads of the fabric have a lower melting point than the other threads of the fabric on the paper side 6. The lower melting point of some fabric threads processed on the drive side 8 also results in the same temperature of the pressure plates 50, 51 sinks the pressure plate 51 on the drive side 8 deeper into the fabric structure than on the paper side. It may be expedient to provide the threads of the drive side 8 completely of a material which has a lower melting point than the material of the threads on the paper side 6 of the fabric belt 1.

Als Materialmix können die Fäden auf der Antriebsseite des Gurtes aus Polypropylen bestehen, während die übrigen Fäden des Gewebegurtes aus Polyester bestehen. Polypropylen hat einen Schmelzpunkt von ca. 150°, während Polyester einen Schmelzpunkt von ca. 180° hat.As a mix of materials, the threads on the drive side of the belt can be made of polypropylene, while the remaining threads of the fabric strap made of polyester. Polypropylene has a melting point of about 150 °, while polyester has a melting point of about 180 °.

Das Material mit dem niedrigeren Schmelzpunkt kann auch als Beschichtung 55 auf einem Faden 80 aus Material mit einem höheren Schmelzpunkt aufgebracht sein und auf der Antriebsseite 8 verarbeitet werden. Fig. 7 zeigt einen derartigen Faden im Schnitt.The lower melting point material may also be applied as a coating 55 to a thread 80 of higher melting point material and processed on the drive side 8. Fig. 7 shows such a thread in section.
