The present invention was accomplished in order to provide a method for producing a sheet containing fine fibers, which enables production of a sheet containing fine fibers without producing wrinkles. The present invention provides a method for producing a sheet containing fine fibers comprising a coating step of coating a dispersion containing fine fibers having a fiber diameter of 1000 nm or smaller on a base material, and a drying step of drying the dispersion containing fine fibers coated on the base material to form a sheet containing fine fibers.

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.

A method of forming a fibrous web including the steps of providing a fiber slurry, depositing the fiber slurry between an inner forming wire and an outer forming wire, wherein the outer forming wire comprises a structured fabric and the inner forming wire contacts a segment of a forming roll, and rotating the forming roll so that the fiber slurry moves into contact with the structured fabric.

A drying hood for drying a fibrous web, such as a tissue paper web, includes a plurality of nozzle boxes for supplying or discharging air and a housing that at least partially surrounds the nozzle boxes. The nozzle boxes are each individually mounted on the housing by a first bearing and a second bearing. The two bearings allow at least one movement of the nozzle box relative to the housing along a longitudinal axis of the nozzle box and/or at least one movement in a direction transverse thereto, along a transverse axis of the nozzle box. The two bearings have translational degrees of freedom differing by one. A drying arrangement having a drying cylinder and the drying hood is also provided.
