Die Erfindung betrifft ein Band, insbesondere Transportband oder Prozessband für bahnverarbeitende und/oder bahnherstellende Maschinen, wie insbesondere Papier-, Karton- oder Tissuemaschinen nach dem Oberbegriff des Patentanspruchs 1 und des Patentanspruchs 2.The invention relates to a belt, in particular conveyor belt or process belt for web-processing and / or web-making machines, in particular paper, board or tissue machines according to the preamble of patent claim 1 and
Beispielsweise ist aus der Offenlegungsschrift
Transportbänder werden in Papiermaschinen bspw. eingesetzt, um eine Papierbahn in der Papiermaschine von einer ersten Transferstelle, an der die Materialbahn von einer Bespannung auf das Band übergeben wird, zu einer zweiten Transferstelle zu transportieren, an der die Materialbahn von dem Band an eine weitere Bespannung übergeben wird. Oftmals wird die Papierbahn auf solchen Transportbändern zwischen den beiden Transferstellen durch einen Pressspalt geführt. In diesem Fall findet dann bspw. eine Glättung der Papierbahn durch das Transportband statt.For example, conveyor belts are used in paper machines to transport a paper web in the paper machine from a first transfer point, at which the material web is transferred from a fabric to the belt, to a second transfer point, at which the material web from the belt to another clothing is handed over. Often, the paper web is guided on such conveyor belts between the two transfer points through a press nip. In this case, then, for example, a smoothing of the paper web by the conveyor belt instead.
Die in Rede stehenden Transportbänder haben in der Regel eine lastaufnehmende Basisstruktur, die bspw. als Gewebe ausgebildet ist, auf der eine die Papierseite bereitstellende Polymerschicht angeordnet ist, die oftmals impermeabel ist.The conveyor belts in question usually have a load-bearing base structure which, for example, is designed as a fabric on which a polymer layer providing the paper side is arranged, which is often impermeable.
Nachteilig bei den aus dem Stand der Technik bekannten Transportbändern ist, dass die sich in Längsrichtung des Bandes erstreckenden Bandränder oftmals "ausfransen" oder abgerieben werden, was zu einer Schwächung der Bandränder führt.A disadvantage of the conveyor belts known from the prior art is that the band edges extending in the longitudinal direction of the band often "fray" or are rubbed off, which leads to a weakening of the band edges.
Es ist die Aufgabe der vorliegenden Erfindung Transportbänder der eingangs genannten Art dahingehend zu verbessern, dass deren Bandränder verschleißbeständiger sind.It is the object of the present invention to improve conveyor belts of the type mentioned in that their band edges are more wear resistant.
Hat das Band nur eine papierseitige Polymersicht, so wird die Aufgabe gelöst durch ein Band zum Transport einer Materialbahn für eine bahnherstellende und/oder bahnverarbeitende Maschine, insbesondere Papier-, Karton oder Tissuemaschine, welches in seiner Querrichtung beidendseitig durch je eine Längskante begrenzt wird, wobei das Band eine lastaufnehmende Basisstruktur und eine auf der Basisstruktur angeordnete die Papierseite des Bandes bereitstellende Polymerschicht aus einem ersten Polymermaterial umfasst und wobei im Bereich zumindest einer Längskante eine zumindest einen Teil der Längskante bereitstellende Randverstärkung dadurch gebildet ist, indem im Bereich der Längskante die papierseitige Polymerschicht in Querrichtung des Bandes über die Basisstruktur ragt und eine dadurch gebildete sich in Längsrichtung des Bandes erstreckende Stufe zumindest abschnittweise mit einem zweiten Polymermaterial gefüllt ist, wodurch die Randverstärkung zumindest einen Teil der Längskante des Bandes bildet.If the tape has only a paper-side polymer layer, the object is achieved by a belt for transporting a material web for a web-producing and / or web-processing machine, in particular paper, board or tissue machine, which is limited in its transverse direction at both ends by a respective longitudinal edge, wherein the strip comprises a load-bearing base structure and a polymer layer of a first polymer material which provides the paper side of the strip and wherein in the region of at least one longitudinal edge an edge reinforcement providing at least part of the longitudinal edge is formed by the paper-side polymer layer in the region of the longitudinal edge Transverse direction of the belt protrudes beyond the base structure and a step formed thereby extending in the longitudinal direction of the belt is at least partially filled with a second polymer material, whereby the edge reinforcement at least a portion of the Längsk Ante of the band forms.
Hat das Band eine papierseitige und eine laufseitige Polymerschicht, so wird die Aufgabe gelöst durch ein Band zum Transport einer Materialbahn für eine bahnherstellende und/oder bahnverarbeitende Maschine, insbesondere Papier-, Karton oder Tissuemaschine, welches in seiner Querrichtung beidendseitig durch je eine Längskante begrenzt wird, wobei das Band eine lastaufnehmende Basisstruktur umfasst, die zwischen einer papierseitigen Polymerschicht aus einem ersten Polymermaterial und einer lauftseitigen Polymerschicht angeordnet ist und wobei im Bereich zumindest einer Längskante eine zumindest einen Teil der Längskante bereitstellende Randverstärkung dadurch gebildet ist, indem im Bereich der Längskante die beiden Polymerschichten in Querrichtung des Bandes über die Basisstruktur ragen und eine dadurch gebildete sich in Längsrichtung des Bandes erstreckende Nut zumindest abschnittweise mit einem zweiten Polymermaterial gefüllt ist.If the tape has a paper-side and a running-side polymer layer, the object is achieved by a belt for transporting a material web for a web-producing and / or web-processing machine, in particular paper, board or tissue machine, which is limited in its transverse direction at both ends by a respective longitudinal edge wherein the band comprises a load-bearing base structure which is arranged between a paper-side polymer layer of a first polymer material and a running polymer layer and wherein in the region of at least one longitudinal edge an edge reinforcement providing at least part of the longitudinal edge is formed by the two in the region of the longitudinal edge Polymer layers in the transverse direction of the belt protrude beyond the base structure and a groove formed thereby extending in the longitudinal direction of the belt is at least partially filled with a second polymer material.
Mit anderen Worten umfasst die Randverstärkung ein Polymermaterial und in Querrichtung des Bandes betrachtet ragt die papierseitige Polymerschicht (und die laufseitige Polymerschicht) zur Längskante des Bandes hin über ein Ende der Basisstruktur, wobei zumindest ein Teil der Längskante des Bandes dadurch gebildet ist, indem das Polymermaterial zumindest teilweise den über das Ende der Basisstruktur ragenden Abschnitt der Polymerschicht bedeckt und indem das Polymermaterial das Ende der Basisstruktur vollständig bedeckt.In other words, the edge reinforcement comprises a polymer material, and viewed in the transverse direction of the tape, the paper-side polymer layer (and the polymer back-end layer) protrudes toward the longitudinal edge of the tape over one end of the base structure, wherein at least a portion of the longitudinal edge of the tape is formed by exposing the polymeric material at least in part about the end of the basic structure covered portion of the polymer layer and by the polymer material completely covers the end of the base structure.
Die Erfindung basiert auf der Idee, die oftmals verschleißempfindliche Basisstruktur im Bereich des Bandrandes durch ein Polymermaterial zu schützen. Dies wird erfindungsgemäß dadurch erreicht, indem die papierseitige Polymerschicht im Bereich des Bandrandes nach außen über das Ende der Basisstruktur ragt und der Raum, der durch den über das Ende der Basisstruktur ragenden Abschnitt der Polymerschicht und dem Ende der Basisstruktur gebildet wird, zumindest abschnittweise mit einem Polymermaterial gefüllt ist.The invention is based on the idea of protecting the often wear-sensitive basic structure in the area of the band edge by a polymer material. This is inventively achieved by the paper-side polymer layer protrudes in the region of the band edge to the outside over the end of the base structure and the space formed by the over the end of the base structure projecting portion of the polymer layer and the end of the base structure, at least in sections with a Polymer material is filled.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments and further developments of the invention are specified in the subclaims.
Vorzugsweise ist das die Randverstärkung bildende Polymermaterial einstückig ausgebildet.Preferably, the edge reinforcement forming polymer material is integrally formed.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass das die Stufe bzw. die Nut füllende Polymermaterial formkomplementär zur Stufe bzw. Nut ausgebildet ist. Dies kann bspw. dadurch erreicht werden, indem das Polymermaterial formlos, d.h. bspw. in flüssiger Form, in die Stufe bzw. in die Nut gefüllt wird und anschließend verfestigt wird. Das Polymermaterial kann hierbei bspw. durch Wärmeeinwirkung zur Erstarrung oder Verfestigung gebracht werden. Des Weiteren ist es denkbar, dass das Polymermaterial bei der Verfestigung selbst vernetzt und/oder mit dem Polymermaterial der papierseitigen und/oder laufseitigen Polymerschicht vernetzt. Dadurch, dass das Polymermaterial formlos eingebracht wird, kann es alle Hohlräume der Stufe bzw. Nut vollständig ausfüllen. Nach seiner Erstarrung bildet sich das Polymermaterial der Randverstärkung im Berührungsbereich mit der bzw. den Polymerschicht(en) und der Basisstruktur zu diesen formkomplementär ab und ist daher fest mit diesen verbunden.A preferred embodiment of the invention provides that the polymer material filling the step or the groove is designed to be complementary in shape to the step or groove. This can be achieved, for example, by filling the polymer material in an informal manner, ie, for example, in liquid form, into the step or into the groove and then solidifying it. In this case, the polymer material may, for example, be brought to solidification or solidification by the action of heat. Furthermore, it is conceivable that the polymer material itself cross-links during solidification and / or crosslinks with the polymer material of the paper-side and / or running-side polymer layer. The fact that the polymer material is introduced informally, it can fill all cavities of the step or groove completely. After solidification, the polymer material of the edge reinforcement in the contact region with the polymer layer (s) and the base structure forms a complementary shape with respect to these and is therefore firmly connected to them.
Somit ist es denkbar, dass die Randverstärkung mit der zumindest einen Polymerschicht und mit der Basisstruktur stoffschlüssig und / oder kraftschlüssig und / oder formschlüssig verbunden ist.Thus, it is conceivable that the edge reinforcement with the at least one polymer layer and with the base structure is materially and / or positively and / or positively connected.
Unter stoffschlüssigen Verbindungen sind hierbei alle Verbindungen genannt, bei denen die Verbindungspartner durch atomare oder molekulare Kräfte zusammengehalten werden. Beispielhaft ist hierbei eine Verbindung durch Kleben, chemisches Vernetzen oder Vulkanisieren zu verstehen.Under cohesive compounds in this case all compounds are called, in which the connection partners are held together by atomic or molecular forces. By way of example, a connection by gluing, chemical crosslinking or vulcanization is to be understood here.
Unter einer kraftschlüssigen Verbindung soll in diesem Zusammenhang eine Verbindung durch Anwendung von Kraft verstanden werden, bei der der Zusammenhalt der Bindungspartner durch Haftreibung gewährleistet gewährleistet wird.Under a non-positive connection is to be understood in this context, a compound by application of force, in which the cohesion of the binding partner is guaranteed guaranteed by stiction.
In der Regel füllt das Polymermaterial der Randverstärkung die Nut bzw. die Stufe vom Ende der Basisstruktur her zumindest teilweise auf.As a rule, the polymer material of the edge reinforcement at least partially fills the groove or step from the end of the base structure.
Die Nut kann im Querschnitt des Bandes betrachtet beispielsweise so sein, dass der Abstand zwischen den zueinander weisenden Flächen der papierseitigen und der laufseitigen Polymerschicht von innen des Bandes, d.h. vom Ende der Basisstruktur, zur Längskante des Bandes hin konstant bleibt. In diesem Fall ist die Nut bspw. U-förmig. Alternativ dazu ist denkbar, dass die Nut derart ausgebildet ist, dass sich der Abstand zwischen den zueinander weisenden Flächen der papierseitigen und der laufseitigen Polymerschicht vom Inneren des Bandes zur Längskante des Bandes hin vergrößert oder verkleinert. In diesem Fall kann die Nut V-förmig ausgebildet sein. Vergrößert sich die Nut zur Längskante hin, so vergrößert sich das durch das Polymermaterial der Randverstärkung bereitgestellte Verschleißvolumen in Querrichtung vom Ende der Basisstruktur zum Ende der papierseitigen und/oder laufseitigen Polymerschicht hin.The groove may, for example, be viewed in the cross-section of the strip such that the distance between the mutually facing surfaces of the paper side and the running side polymer layer remains constant from the inside of the strip, ie from the end of the base structure, to the longitudinal edge of the strip. In this case, the groove is, for example, U-shaped. Alternatively, it is conceivable that the groove is formed such that the distance between the mutually facing surfaces of the paper-side and the running side polymer layer from the inside of the tape to the longitudinal edge of the tape towards increased or decreased. In this case, the groove may be V-shaped. As the groove increases toward the longitudinal edge, the volume of wear provided by the polymeric material of the edge reinforcement increases transversely from the end of the base structure towards the end of the paper side and / or back side polymer layer.
Vorzugsweise hat das Band über seine gesamte Breite eine konstante Dicke. Dies bedeutet, dass auf der Papier- und der Laufseite des Bandes der Bereich um die Bandränder nicht gegenüber der Bandmitte erhöht ist.Preferably, the band has a constant thickness over its entire width. This means that on the paper and the run side of the tape, the area around the tape edges is not increased relative to the tape center.
Um die Verschleißbeständigkeit des erfindungsgemäßen Bandes weiter zu verbessern, sieht eine bevorzugte Ausgestaltung der Erfindung vor, dass das Polymermaterial der Randverstärkung in Querrichtung des Bandes betrachtet zumindest abschnittweise über die papierseitige Polymerschicht und/oder über die laufseitige Polymerschicht ragt. Somit wird erreicht, dass die Längskante des erfindungsgemäßen Bandes einen in Querrichtung des Bandes über die papierseitige und laufseitige (wenn diese vorgesehen ist) Polymerschicht ragenden Teil hat, der durch die Randverstärkung gebildet ist und der ein Verschleißvolumen der Längskante des Bandrandes darstellt.In order to further improve the wear resistance of the tape according to the invention, a preferred embodiment of the invention provides that the polymer material of the edge reinforcement in the transverse direction of the tape protrudes at least in sections over the paper-side polymer layer and / or over the running polymer layer. Thus, it is achieved that the longitudinal edge of the tape according to the invention has a transverse in the tape on the paper side and the running side (if provided) polymer layer projecting part, which is formed by the edge reinforcement and which represents a wear volume of the longitudinal edge of the band edge.
Vorzugsweise ist das Polymermaterial der Randverstärkung ein anderes Polymermaterial als das Polymermaterial der papierseitigen Polymerschicht und/oder als das Polymermaterial der laufseitigen Polymerschicht.Preferably, the polymer material of the edge reinforcement is a different polymer material than the polymer material of the paper side polymer layer and / or as the polymer material of the running polymer layer.
In diesem Zusammenhang ist es insbesondere sinnvoll, wenn das Polymermaterial der Randverstärkung eine größere Härte und/oder eine größere Abriebbeständigkeit als das Polymermaterial der papierseitigen Polymerschicht und/oder das Polymermaterial der laufseitigen Polymerschicht hat. Hierdurch kann die Verschleißbeständigkeit des Bandrandes weiter verbessert werden.In this context, it is particularly useful if the polymer material of the edge reinforcement has a greater hardness and / or a greater abrasion resistance than the polymer material of the paper-side polymer layer and / or the polymer material of the running polymer layer. As a result, the wear resistance of the band edge can be further improved.

Das Polymermaterial der einen oder beiden Polymerschichten umfasst vorzugsweise Polyurethan. Das Polymermaterial der Randverstärkung kann Polyurethan, Silikon, Polyamid, Epoxydharz, Polyolefin, Polyester oder Amide allein oder in Kombination umfassen.The polymer material of the one or both polymer layers preferably comprises polyurethane.
