摘要： A dewatering roll (10) comprises a roll body (20), a mantle support structure (30) and a mantle (40). The mantle support structure (30) is attached around the roll body (20). The mantle (40) is attached against an outer surface (36) of the mantle support structure (30). The mantle (40) has a plurality of through holes (42) constituting mantle flow paths (44). The mantle support structure (30) presents support flow paths (38) from the outer surface (36) of the mantle support structure (30). The support flow paths (38) are in fluid contact with the mantle flow paths (44). The outer surface (36) of the mantle support structure (30) has a static geometric shape defining an envelope having a smaller radius in vicinity of each axial end (15) than in vicinity of a centre (16). Thereby, the inner surface (48) of the mantle (44) assumes the shape of the envelope.

摘要： A method for producing a Yankee dryer cylinder, or Yankee cylinder, comprises the steps of disposing of a first and of at least a second cylindrical portion of shell. These are made of steel, have the same diameter and are provided with a plurality of grooves at an internal surface. In particular, the portions of shell, at a respective end, are provided of respective flange portions. The method provides to coaxially position the portions of shell up to arrange respective coupling surfaces of the flange portions adjacent one to the other. Then the engagement of the portions of shell is provided by means of a plurality of clamping members, each of which arranged to clamp the adjacent flange portions. Then, it is provided the circumferential welding of the cylindrical portion of the shell that are opposite to the flange portions, and the removal of the clamping members and of the flange portions.

摘要： [Problem] To provide a method for spraying a chemical solution that makes it possible to uniformly apply a chemical solution onto a moving body and that exhibits excellent spraying efficiency. [Solution] The present invention is directed to a method for spraying a chemical solution in which, in a dry part D of a paper-making machine, a chemical solution is continuously sprayed onto a moving body that guides wet paper X, while a nozzle device S is reciprocating in directions orthogonal to a moving direction of the moving body with the moving body in motion, wherein: the moving body is a cylindrical dryer roller D1 or an endless canvas K1; and a travel distance H that the nozzle device S moves during a single rotation of the moving body and a width W of a sprayed area that is formed on the moving body by the nozzle device S satisfy the relationship represented by the following expression: 0.5 ‰¤ H/W ‰¤ 20.

摘要： The steel-made Yankee cylinder includes a cylindrical shell (11) joined to two ends (13;15), to which are fixed respective support journals (3). The cylindrical shell (11) is joined to the ends through a plurality of screws (63) substantially parallel to the axis (A-A) of the cylindrical shell (11). On the internal surface of each end (13, 15) is welded a ring (61) forming an internal support for the respective end of the cylindrical shell surrounding said ring, at least part of the flexural stress on said cylindrical shell being released on said ring.

摘要： A paper drying cylinder or roller (1) for paper mills, said cylinder or roller rotating about a rotating shaft (2) on bearing elements (2') of a framework (30) that holds at opposite sides the rotating shaft (2). In particular, the paper drying cylinder (1) rotates within the structure of two drying hoods (4, 5) that remove the moist air stream that forms while the continuous paper web is dried. The active surface of the Yankee cylinder (1) is cylindrical surfaces (1'), whereas the head walls (3) does not have any function related to paper drying but, on the contrary, are heat loss surfaces. According to the invention, a protection carter (40) is provided arranged about the rotating shaft (2) proximate to one of the head walls (3) that are connected to the framework (30) in such a way that the carter (40) during the rotation of the paper drying cylinder (1) stays motionless and faces the head wall (3) carrying out a thermal insulating function. This way, heat loss towards the environment and the steam consumption to heat cylinder 1 is reduced.

摘要： The invention relates to a drying roll (10) for drying a fibrous material web, in particular a paper, cardboard or tissue web in a machine for producing and/or finishing said fibrous material web. The roll can be heated on the interior by a gaseous heat transfer medium and the internal surface of its jacket (12) is provided with elevated sections (14) that extend at least radially inwards, the height of said elevations being greater than the average radial thickness of the condensate layer (16) that forms on the internal surface of the cylinder jacket (12) during operation. The roll is equipped with elements (30, 34, 42, 44) that drain condensate from the condensate chamber that incorporates the areas lying between the elevations (14). The drying roll is characterised in that the condensate chamber or at least one condensate sub-section is in hydraulic contact with at least one front-end region of the cylinder (20).
