Abstract: This invention relates to a system and a method for optimization of the process performance of a web-processing machine, in particular a machine for the production or further processing of paper, paperboard or tissue, including the following steps: storage of specific data of a component on a data storage unit fitted to the component; and/or measurement of relevant properties of the component by way of a sensor unit fitted to the component; sending of the specific data and/or the measured relevant properties to an open-loop control unit and/or a closed-loop control unit; and optimization of the process performance by way of the open-loop control unit and/or the closed-loop control unit using specific data and/or the measured properties of the component.

Abstract: A rotary part, in particular a spreader roller for a web-processing machine has a supporting core with a longitudinal axis, said supporting core being mounted at its two longitudinal ends, and having an elastically flexible outer sleeve which surrounds the supporting core in its circumferential direction and extends, in at least some sections, between the two longitudinal ends of the supporting core. The outer sleeve on the supporting core is non-displaceably mounted on at least one bearing and that the outer sleeve is mounted on at least one displacing point at a distance from the bearing so as to be displaceable perpendicular to the longitudinal axis of the supporting core in order for the curvature of the outer sleeve to be adjustable.

Abstract: The invention relates to a suction or ventilation roll of a machine for producing and/or finishing a paper, cardboard, tissue or other fibrous material web (2). Said roll comprises a rotatable, perforated roll jacket (1) and at least one pressure zone (9), which only extends over part of the roll circumference and is formed by a fixed pressure compartment (6) located in the interior of the roll and open towards the roll jacket (1). The pressure compartment (6) is connected to a negative- or excess-pressure source and is sealed in relation to the roll jacket (1) by means of at least one sealing element (7). One aim of the invention is to reduce the noise emissions. To achieve this, a substantially air-tight cover (5), which runs in the direction of the circumference and is located outside the pressure compartment (6), adjoins a sealing element (7), said cover making contact with the roll jacket (1), or being placed at a distance of less than 100 mm to the latter.

Abstract: Disclosed is a heated cylinder (1) for heating a paper web, cardboard web, tissue web, or another fiber web in a machine used for producing and/or refining the fiber web. Said heated cylinder (1) comprises a cylinder sleeve which is impinged upon at least in part from the inside by a hot fluid and is provided with at least one inner and an outer sleeve layer (5, 6). The inventive heated cylinder (1) is characterized in that the two sleeve layers (5, 6) are separated from each other by a hollow space into which the fluid can be introduced.

Abstract: The invention relates to a suction or blowing cylinder of a machine which is used to produce and/or shape paper, cardboard, tissue or another fibrous material (2). Said cylinder comprises a rotatable, perforated cylinder covering (1) and at least one pressure area (4) which is connected to a lower pressure source or a high pressure source and is sealed in relation to the cylinder covering (1) with the aid of at least one sealing element (5, 6). The invention is characterised in that the sealing element (5, 6) is embodied in a flat-shaped manner and is arranged in the vicinity of the inner wall of the cylinder covering (1).

Abstract: Sealing device for sealing at least one zone of underpressure or overpressure adjoining a moving surface that includes at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction. The sealing device includes a sealing section located at the front and a ventilation section located at the rear. The sealing section is structured to sealingly interact with the moving surface; and the ventilation section is structured and arranged to form a gap with the moving surface that widens in the surface running direction.
