Abstract: A method for producing a structured fibrous web, in particular a tissue web, includes bringing a fibrous suspension into contact with at least one structured forming belt and dewatering by using at least one dewatering element, in particular a suction element. The at least one structured forming belt includes a layer of polymer foam providing a paper-contacting side of the structured forming belt. The structure of the foam layer is at least partially transferred to the fibrous web. A structured forming belt and a machine for producing a fibrous web are also provided.

Abstract: A cover device (10) is disclosed for use in a dewatering shoe or other drainage device of a papermaking machine. The cover device (10) includes a plate (12) of expanded metal which defines a plurality of elongate holes (14, 15, 16, 17, 18, 19, 20 and 21) for the passage therethrough of water as indicated by the arrow (22) removed from a web W disposed on a dewatering screen (24) moving in a machine direction MD relative to the cover device (10). The arrangement is such that the dewatering screen (24) is disposed between the web W and the cover device (10) so that the water (22) is removed from the web W through the dewatering screen (24) and then through the elongate holes (14 to 21).

Abstract: A paper machine screen which is formed as a transverse thread-bound, multi-layer fabric. Binding transverse threads extend respectively both in an upper fabric layer and in a lower fabric layer and hereby bind the lower fabric layer to the upper fabric layer. The binding transverse threads form functional transverse thread pairs within the total repeat, the transverse threads of which alternately complete the first weave. In the total repeat, the functional transverse thread pairs in the upper fabric layer are arranged in groups of respectively two or more functional transverse thread pairs arranged directly one after another, when seen in a longitudinal direction.

Abstract: The invention relates to a device for dewatering a fibrous web with a press zone which is formed by a mating element with a curved surface and a permeable press belt which wraps at least partially around the curved surface and has a running side and a contact side contacting a second side of the fibrous web. A permeable carrier belt arranged between the mating element and the fibrous web guides the fibrous web through the press zone. The device is configured so a fluid can flow through the press belt, the fibrous web, and the permeable carrier belt at least in a part region of the press zone. The permeable press belt is configured to generate a pressing pressure in the press zone when a tensile stress of at least 20 kN/m is applied and the contact side is adapted to a quality of the fibrous web produced.

Abstract: A fabric for papermaking machines is produced from a belt-shaped film substrate which consists essentially of a non-oriented polymer. The film substrate is bent in such a way that the two end edges of the film substrate adjoin one another. Subsequently, the two adjacent end edges are joined to one another in a material-to-material manner. The endless film substrate which is formed in this way is finally stretched in the circulating direction of the endless film substrate which is formed in this way.

Abstract: A fabric for a papermaking machine is configured as a belt, the two side edges of which are configured in each case as closed lines. Furthermore, the belt is formed in one layer from a solid material and has pores which form passages between the two surfaces of the belt. The belt has regions with a width of approximately 400 micrometers (μm) or less. These regions extend in the longitudinal direction over the entire circumference of the belt, transversely with respect to the side edges, and include no pores formed therein.

Abstract: A twin-wire belt press is disclosed for dewatering a fiber suspension and forming a continuous web of the fiber suspension. The twin wire belt includes a plurality of upper and lower rolls, a perforated roll and endless upper and lower wire belts. Dewatering tables are used to support the endless upper and lower wire belts and form a wedge-shaped pressure space between the endless upper and lower wire belts for initially pressing and dewatering the fiber suspension and forming a web therebetween. Roll members, including at least two press rolls which form press roll nips with the perforated roll and another roll, press and dewater the web between the endless upper and lower wire belts.
