Abstract: A dewatering device has a dewatering box and a plurality of dewatering strips. A contour of at least one dewatering strip changes over its length. There is also described a machine for the production of a fibrous web, such as a paper, cardboard or tissue web, with a dewatering device of this kind, and to the use of the latter in a machine of this kind.

Abstract: A method of operating a machine for producing a fibrous web. The machine has a de-watering device with a plurality of pivotally embodied de-watering strips. In the method, an inclination angle of at least one of the de-watering strips is modified as a function of at least one parameter. The modification is effected by way of the pivoting installation which is activated by a control installation. The actual inclination angle of the at least one de-watering strip to be pivoted is detected and transmitted to the control installation. The control installation activates the pivoting installation as a function of the transmitted inclination angle.

Abstract: A drying and smoothing apparatus for a machine which produces or processes a layer of material, specifically for machines that produce or process paper, cardboard or tissue, the drying and smoothing apparatus including a heated drying and smoothing cylinder having a curved external surface, the drying and smoothing cylinder configured to rotate, a pressurizing jacket encasing a portion of a curved external surface of the drying cylinder to form a pressure zone, a plurality of stacked sealing assemblies configured to seal the pressure zone from an ambient, the plurality of stacked sealing assemblies being supported on a first end and a second end of the curved surface of the drying and smoothing cylinder, wherein each of the plurality of stacked sealing assemblies include at least three seals, the seals pressed inward against the curved external surface of the drying and smoothing cylinder and stacked in sequence axially outward from the pressure zone to the ambient.

Abstract: A pressure hood with a pressure hood body to be used in conjunction with especially a heated cylinder in a machine for the production and/or conversion of a fibrous web, especially a paper-, cardboard- or tissue web, and a seal assembly to seal said pressure hood body against the cylinder, provides that the seal assembly can be inserted into or removed from the pressure hood body—particularly when the pressure hood is installed on the cylinder—through a movement in axial direction relative to the pressure hood body.

Abstract: A dryer arrangement for drying a paper-, cardboard-, tissue- or other fibrous web in a machine for the production and/or conversion of same includes: at least one heated dryer cylinder which is wrapped at least partially by the fibrous web and at least one outer support belt; a pressure hood which impinges the dryer cylinder in the wrap area with a pressurized liquid or gaseous medium, whereby the temperature of the medium is lower than the temperature on the outside of the dryer cylinder in the wrap area; and at least one support belt which is routed over a guide roller immediately prior to and/or after the wrap of the dryer cylinder, the diameter of the dryer cylinder being greater than 1.5 m, the diameter of the guide roller being greater than 400 mm, and the angle of wrap of the support belt being greater than 150°.
