A belt (10) for a sleeve roll forms a closed loop and has an inner surface (11), an outer surface (12), an elastic body (15), and a reinforcing structure (30). The reinforcing structure has first yarns (31a) arranged to a first direction (D1) of the belt, and second yarns (32a) arranged to a second direction (D2) of the belt which is parallel or substantially parallel to a travel direction of the belt, and/or perpendicular or substantially perpendicular to the first direction (D1). The belt (10) is configured to stretch elastically more in the second direction (D2) than in the first direction (D1) so that it will return to its original length after forces stretching the belt have been removed. This invention further relates to an arrangement including a belt and a sleeve roll. This invention further relates to a use of a belt.

A tissue machine (1) has a Yankee (3) and a shoe roll (4) that forms a nip with the Yankee (3). The nip has a maximum extension from an entry point (7) to an exit point (8). A flexible belt (9) forms an outer circumference of the roll (4). A fabric (10) carries a fibrous web (W) to the nip and passes through the nip with the web. The fabric (10) reaches the circumference of the roll (4) at a first contact point (11) and wraps the roll (4) from the first contact point to the nip. A mechanical support (12) inside the belt (9) supports the belt (9) between the first contact point (11) and the nip. The fabric (10) wraps the roll (4) from the first contact point (11) by more than 80°. The invention also relates to a method of operating the machine.

A shoe press belt (10) for a shoe press has an inner surface (11), an outer surface (12), an elastomer body and a support structure (20, 21, 22, 23) for the elastomer body. A plurality of parallel dewatering grooves (50, 50a, 50b) are on the outer surface (12) of the shoe press belt (10), with a ridges (53) provided between two adjacent dewatering grooves (50a, 50b). The dewatering grooves (50, 50a, 50b) have a first wall (60), a second wall (70), and a bottom (80) therebetween. At least the first wall (60) of the dewatering groove (50, 50a, 50b) has a plurality of parallel auxiliary grooves (100, 100a, 100b). A paper, board or pulp drying machine has said shoe press belt (10). A method for installing the shoe press belt (10) is provided.

A method for treating a pulp web in a paper or tissue machine with an extended-nip press unit. This extended-nip press unit includes a shoe press roll with a revolving press belt and a backing roll, where the pulp web is dewatered in the extended press nip between the backing roll and the press belt and where the pulp web is carried on the revolving press belt of the press roll after the extended press nip to a transfer fabric that receives the pulp web. The transfer fabric is guided over a stationary transfer device in the transfer area. A corresponding device for treating the pulp web.

A press cover has at least one polymer layer in which a reinforcing structure is embedded. The reinforcing structure has at least one reinforcing thread as a longitudinal thread which runs in the longitudinal direction of the press cover. The at least one reinforcing thread itself is produced by interlacing a plurality of fibers or fiber bundles with one another. There is also described the use of such a press cover, as well as a press roll and a shoe press.
