Mantle for a press roller with radial spring elasticity, in a papermaking machine, has center and flanking zones of different characteristics with a smooth characteristic transit between them

摘要

The mantle (1) for a press roller (2), in a papermaking machine, is at least partially around the roller with a cylindrical running surface and with radial (R) spring elasticity. (1) Has at least two different zones (12,13) of different characteristics, on the axial direction (A). The center zone (12) is in contact with the paper web, flanked by outer zones (13), with a smooth characteristic transit between them. The mantle (1) for a press roller (2), in a papermaking machine, is at least partially around the roller with a cylindrical running surface and with radial (R) spring elasticity. (1) Has at least two different zones (12,13) of different characteristics, on the axial direction (A). The center zone (12) is in contact with the paper web, flanked by outer zones (13), with a smooth characteristic transit between them. The end zones (14) of the mantle are supported by carriers (5) and roller end covers (6), with a bellows transit shape (3) between the horizontal and vertical mantle walls.
