摘要： A sealing strip and a sealing device for sealing a negative-pressure zone of a suction roller for a machine for producing or processing a fibrous web, such as a paper, board or tissue machine. The stealing strip has an upper face, which forms a sealing surface of the sealing strip, and the sealing strip includes a sensor unit, which has a first temperature sensor at a first distance from the sealing surface and a second temperature sensor at a second distance from the sealing surface. The first distance is smaller than the second distance. The sealing strip is formed of a base material and a protective material which is different from the base material, and the sensor unit is embedded, in particular cast, into the protective material.

摘要： A sealing device seals a pressure or vacuum zone in a roller with a perforated roller sleeve that rotates relative to the sealing device. A sealing strip and a format limiter seal the pressure or vacuum zone. The sealing strip has a lubricant opening formed as an upwardly open depression. A sealing face of the sealing strip and of the format limiter brace against the roller sleeve, and the roller sleeve runs onto the sealing strip at the front end and runs off the sealing strip at the rear end. A lubricant opening of a second type which is open toward the upper side, but not toward the end side against which the format limiter is placed, and/or a lubricant opening of a third type is upwardly open and toward that end side against which the format limiter is placed, and/or at least in portions no lubricant opening is provided.

摘要： A sealing strip for sealing a suction zone of a suctioned roll of a machine for producing and/or processing a fibrous web has wear volume, which is gradually worn away by tribological contact with the roll. The sealing strip system further includes a sensor system for detecting the state of wear of the sealing strip, and an evaluation unit. The sensor system is embedded in a sensor channel extending within the sealing strip in the longitudinal direction at the wear volume across substantially the entire length of a sealing surface of strip, and is connectable to the evaluation unit and/or to a unit for supplying the sensor system with a medium for generating information via a connection provided on the lower side of the sealing strip, and leading out of the strip on the side of the wear volume facing away from the sealing surface.

摘要： A roller has a movable roller sleeve and a positive-pressure or negative-pressure zone inside the roller sleeve. The zone is sealed outwardly by a sealing installation with at least one sealing strip. The sealing strip in the radial direction of the roller is movable from the roller toward the inner side and away therefrom and the sealing strip has a lubricant outlet opening connected to a supply line for delivering lubricant to between the inner side of the roller sleeve and the sealing face. The supply line includes one part running within the sealing strip and one part running outside the sealing strip but within the roller. The part of the supply line within the roller, on its length which is routed outside the sealing strip, includes a first portion that is longer than a second line portion. The second line portion is more flexural than the first line portion.

摘要： A method and a suitable device determine the contamination of a suction roller of a machine for producing a fibrous web, in particular a paper, cardboard, tissue or pulp web. The method includes the steps of: a. flowing a fluid through a measurement area of a roller shell, wherein either the pressure or the throughflow speed of the fluid is kept constant; b. determining a characteristic variable, wherein the characteristic variable includes the resulting throughflow speed in the case of a throughflow at a constant pressure and of the resulting pressure drop in the case of the measurement at a constant throughflow speed; c. providing one or more reference variables; and d. determining a degree of contamination of the suction roller by way of comparison of the characteristic variable with the reference variable or variables.

摘要： A sealing strip for sealing at least one suction box which adjoins a moving roller sleeve of a suction roller in a machine for manufacturing or processing a fibrous web, such as a paper, tissue, or cardboard-making machine, bears in a sealing manner on the moving roller sleeve. In the region of the at least one sealing strip and/or on the at least one sealing strip and/or in the at least one sealing strip a device for deploying a lubricant which wets the at least one sealing strip is in each case provided. The at least one sealing strip is provided with a lubricant sump which is open counter to a rotation direction of the moving roller sleeve and is connected to the lubrication device. A contamination guard is provided in the lubricant sump.

摘要： A sealing device seals a pressure or vacuum zone of a roller having a roller sleeve which is movable in relation to the sealing device. The sealing device has a sealing strip with an upper side forming a sealing face and a lubricant channel adjoining the sealing face and is formed by at least one groove-type depression in the sealing strip, which extends in the longitudinal direction of the sealing strip. When the sealing device is installed, the sealing face and the opening of the groove-type depression face toward the inner side of the roller sleeve. The lubricant channel is hooked up to a supply line which at least in portions runs within the sealing strip and delivers lubricant between the inner side of the roller sleeve and the sealing face. The sealing strip, at each of its two ends, has a wall delimiting the lubricant channel in its length.

摘要： A sealing strip for a positive or negative pressure zone of a suction or blower roller of a machine for processing and/or producing web material, in particular a paper, cardboard or tissue machine. The sealing strip has a sealing face to be set against and in frictional contact with the inner side of a roller shell for sealing the positive or negative pressure zone during a rotational movement of the roller shell. The sealing strip has a lubricant channel in the form of a cutout from the sealing strip. The lubricant channel is arranged in front of the sealing face. The sealing strip is formed with a first material section at the sealing face and with a second material section at the front wall. The first and second materials are different in at least one physical property, such as modulus of elasticity, abrasion resistance, hardness, brittleness.
