Abstract: A roll arrangement for calendars or super-calendars is provided by the combination of two rolls which together form a press nip wherein one of the rolls is solely deflection-controllable and the other roll is solely temperature-controllable zone by zone. The temperature-controllable roll has a tubular rotatable roll shell and a stationary core extending through the roll shell. The space between the roll shell and the core is divided by means of several peripheral seals into numerous annular chambers. A flow of fluid is guided through each of the annular chambers. The fluid temperature in each annular chamber is independently controllable. Consequently the temperature-controlled roll shell can be heated by the fluid to different degrees along the axis thereof to control its external diameter along each zone. The peripheral seals are sized to have free play in a direction transverse to the roll axis and are constructed as endless, metallic rings. The external diameter of the rings is a trifle smaller than the internal diameter of the roll shell.

Abstract: A roll for calendars or super-calendars has a tubular rotatable roll shell (20) and a stationary core (30) extending through the roll shell. The space (31) between the roll shell and the core is divided by means of several peripheral seals (32) into numerous annular chambers (31a, 31b . . . ). A flow of fluid is guided through each of the annular chambers. The fluid temperature in each annular chamber is independently controllable. Consequently the roll shell (20) can be heated by the fluid to different degrees along the axis thereof to control its external diameter along each zone. The core (30) is only supported at its ends. The peripheral seals (32) are sized to have free play in a direction transverse to the roll axis and are constructed as endless, metallic rings. The external diameter of the rings is a trifle smaller than the internal diameter of the roll shell (20).

Abstract: A method and machine for the manufacturing a fibrous pulp web including a first draining zone and a second draining zone, where the first and second draining zones are successively arranged in the web run direction, where a first side of the web is drained in the first draining zone by pressure acting on the web which increases from an initial pressure to a final pressure, where a second side of the web is drained in the second draining zone by pressure acting on the web which increases from an initial pressure to a final pressure in the web run direction, and where the initial pressure in the second draining zone is less than the final pressure in the first draining zone.
