Abstract (en)

The transport belt (1) for a paper-, cardboard- or tissue processing machine, comprises a load receiving support structure (3), which is completely covered by a polymer surface structure (4) in section-wise manner. The polymer surface structure and the support structure contact themselves directly or indirectly in section-wise manner. A contact area (5) between the support structure and the polymer surface structure includes sections, in which the support structure is moved itself relative to the polymer surface structure. A separating layer (6) is arranged in the contact area. The transport belt (1) for a paper-, cardboard- or tissue processing machine, comprises a load receiving support structure (3), which is completely covered by a polymer surface structure (4) in section-wise manner. The polymer surface structure and the support structure contact themselves directly or indirectly in section-wise manner. A contact area (5) between the support structure and the polymer surface structure includes sections, in which the support structure is moved itself relative to the polymer surface structure. A separating layer (6) is arranged in the contact area. The support structure in the sections receives no adhesive connection with the polymer surface structure. The support structure comprises a fabric, thread arrangement and thread woven fabric. The threads of the support structure are covered with the separating layer in section-wise manner. The separating layer has a material, by which the frictional resistance is reduced in the contact area. The separating layer has wax, starch, oil and silicone. A second surface of the polymer surface structure arranged opposite to the first surface forms the side of the transport belt, which is bringable in contact with the material web. The support structure and the polymer surface structure are immovable relative to each other in the sections of the contact area extending itself in the transverse direction of the transport belt, and are movable relative to each other in the sections of the contact area extending itself in the longitudinal direction of the transport belt. The transport belt is impermeable to the fluid.

Abstract (de)

Die Erfindung betrifft ein Transportband (1) für eine bahnverarbeitende Maschine, insbesondere Papier-, Karton- oder Tissuemaschine, mit einer Last aufnehmenden Trägerstruktur (3), welche zumindest abschnittweise von einer polymeren Flächenstruktur (4) ummantelt wird, wodurch sich die polymere Flächenstruktur (4) und die Trägerstruktur (3) abschnittweise mittelbar oder unmitttelbar kontaktieren. Die Erfindung ist dadurch gekennzeichnet, dass der Kontaktbereich zwischen der Trägerstruktur (3) und der polymeren Flächenstruktur (4) Abschnitte umfasst, in denen sich die Trägerstruktur relativ zur polymeren Flächenstruktur bewegen kann. Diese können zum Beispiel durch eine Trennlage (6) gebilded sein.
