Abstract: A circulating water preparation system for cooling plants, a cooling system, in particular a recooling system, and a method for operating such a cooling system. In such a cooling system a surface of a heat exchanger is cooled by wetting with water, the water is collected in a collecting tank and returned by means of a water circuit for the renewed wetting of the surface of the heat exchanger. The method is characterised in that the water is purified by means of a filter, in particular a membrane filter. As a result considerably less biocide is needed to keep the water free of germs, in particular legionella, compared to conventional cooling systems or methods for operating such cooling systems.

Abstract: The invention relates to a guiding device for a continuous paper sheet comprising at least one guiding element which is disposed downstream with respect to an application group and used in the form of an air circulating channel in order to ensure a contactless guiding in a machine producing and/or processing a continuous material sheet, in particular a paper or paperboard sheet. Said guiding element consists of a guiding surface made at least partially of an air-permeable porous material which is exposed to a compressed air pressure in such a way that air can circulate therethrough, thereby forming an air cushion between said guiding surface and a moving material sheet.

Abstract: The present invention provides a suction roll system in a drying section of a machine for manufacturing a fibrous web, the suction roll system including a suction roll having an outer circumferential surface. The circumferential surface defines holes configured for attracting the fibrous web by suction and includes regions, more than two of the regions including the holes, at least two of the regions relative to one another having different numbers of the holes per unit area or having the holes with different diameters per unit area. The circumferential surface has strips which extend in a circumferential direction, at least one strip which extends in a helical shape over the circumferential surface, or strips which extend either substantially in a direction of a longitudinal axis of the suction roll or diagonally relative to the longitudinal axis. The regions include the strips.

Abstract: The invention relates to a web-guiding device comprising at least one directing element (10) for guiding a web in a contactless manner in a machine that is used for producing and/or treating a moved web of material (1), especially a paper or cardboard web. Said directing element (10) is provided with a directing surface (12) that is made at least in part of air-permeable porous material (14) which can be impinged upon by compressed air so as to form an air cushion (18) between the directing surface (12) and the moved web of material (1) via the air (16) flowing through said porous material (14). The directing surface (12) is divided into at least one web transfer zone (2, 4) and a web-guiding zone (3) along the direction of movement (2) of the web of material. Said zones (2, 4; 3) are embodied so as to allow for a different air throughput.

Abstract: A system for computer assisted monitoring of a cross profile of a quality parameter of a material web, especially a paper or cardboard web during its production and/or conversion, which includes a measuring system for measuring the cross profile, at least one computer based operations and logic unit for the determination of the standard deviations of at least two interference profiles that are representative for different interferences in the form of different peak groups in the measured cross profile. The different peak groups differentiate in that their peaks have different width ranges. Elements for storage, display and/or further processing of the determined standard deviations are also included.
