    摘要： A drying section of a paper machine includes a plurality of individual drying groups, wherein the drying cylinders of a drying group are served by 2 respective dryer wire or felt that passes over drying cylinders of the drying group and presses a web to be dried against the surface of the drying cylinders. The invention is adapted for either single tier or double tier drying groups. At least one press roll is disposed between and separates two of the drying groups. In one embodiment, the at least one press roll forms a nip with the adjacent drying cylinder, either upstream or downstream, to define a dewatering nip through which the web passes. A dewatering belt passes over the press roll in the nip. The wire for a respective drying group is guided away from the dewatering nip so that only the web and the dewatering belt pass through the press nip. In alternate embodiments, two press rolls may be disposed between the adjacent drying groups, and the two press rolls define a press nip between them. A respective dewatering belt passes over each of the press rolls. One of those press rolls may also be in contact with and define a press nip with the adjacent drying cylinder in the adjacent drying group. An open draw free path may be defined between one of the press rolls and the adjacent drying cylinder.

    摘要： Calendering takes place in a calendering zone which operates under pressure with application of temperature and moisture. The desired smoothness is achieved with a correspondingly long dwell time of the material web in a correspondingly long calendering zone in view of the speed of web travel. A web which is still wet is guided between parallel heatable surfaces which are arranged on both sides of the web and face each other through the web and can each be pressed against the web. The surfaces are designed to form and hold a given precise contour of the calendering zone over its full length. One surface is constructed e.g. as a casing of a heated roller and the second surface is constructed as an endless flexible belt which can be pressed in a direction towards the roller casing by means of a concave supporting element. If wished, the web can be calendered on both sides with the method.

    摘要： In a double wire former of a paper machine, a first continuous wire (1) is fed onto an at least partially curved guiding surface (4) so as to converge with a second wire (2), wherein the guiding surface (4) is movable in a form-locked manner relative to the wires. After the dewatering section described above, a further guiding surface (7) follows which, in advantageous embodiments, has an opposite sense of curvature and is fixedly located.

    摘要： The ledge is arranged transverse to the machine direction in a substantially flexure resistant manner and is adjustable for guiding the wires between which a web of material is formed. The ledge contains a guide surface which faces the wires and has a special contour. For improved control of the pressure changes occurring in the region of the ledge, the ledge contains a supporting member and a pressing member which contains the guide surface. A pressing device is supported at the supporting member and the pressing member can be adjusted in a direction relative to the wires as well as relative to the supporting member by using the pressing device for simultaneously elevating the pressing member and inclining the pressing member with respect to the machine direction. Advantageously the pressing device constitutes a hose which is subjected to a pressurizing medium and thereby deformable. The hose is at least partially imbedded into the supporting member such that its deformation causes movement of the pressing member. For simultaneously inclining the pressing member during such movement, a connecting member is provided between the pressing member and the supporting member. The ledge permits the adjustment of optimum pressures along a sheet forming zone whereby the sheet formation is improved.
