Abstract
A press roll belt is arranged to be used in connection with a roll (10) forming a press nip. The belt (12) of the press roll (10) is provided with a groove pattern formed of intersecting grooves (11A, 11B). A press concept has at least one press nip formed between two rolls (30, 32) to remove water from a web. At least one press nip (NA) of the press concept is formed such that the cover (22) or the belt (12) of at least one roll (30A, 32A) forming the press nip is provided with groove patterning formed of intersecting grooves (11A, 11B; 21A, 21B).
Claims19
A press roll belt which is arranged to be used in connection with a roll forming a press nip, wherein the belt of the press roll is provided with a first groove pattern formed of first intersecting grooves of a first depth, and a second groove pattern formed of second intersecting grooves of a second depth which is less than the first depth.
A press concept which comprises at least one press nip formed between two rolls to remove water from a web, wherein at least one press nip of the press concept is formed such that a belt of at least one roll forming the at least one press nip is provided with a first groove patterning formed of first intersecting grooves of a first depth, and a second groove patterning formed of second intersecting grooves of a second depth which is less than the first depth.
A press concept which comprises at least one press nip formed between two rolls to remove water from a web, wherein at least one press nip of the press concept is formed such that a cover of at least one roll forming the at least one press nip is provided with a first groove patterning formed of first intersecting grooves of a first depth, and a second groove patterning formed of second intersecting grooves of a second depth which is less than the first depth.
A press roll belt in a paper, board or pulp machine which is arranged to be used in connection with a roll forming a press nip, the press roll belt comprising:
- recessed portions defining a plurality of first parallel grooves;
- portions defining a plurality of second parallel grooves extending across the first parallel grooves, the first grooves intersecting the second grooves at a first angle;
- portions defining a plurality of third grooves parallel to the first grooves, and extending to a depth which is less than the depth of the first grooves;
- and
- portions defining a plurality of fourth grooves parallel to the second grooves which intersect the third grooves and which extend to a depth which is less than the depth of the second grooves.
