Abstract (en)
[origin: EP1318232A2] The calender (1), to polish the surface of a paper or cardboard web, has at least two rollers (3,4) bearing against a common rotating mantle (7) forming nips (10,11) according to the number of rollers. The mantle is supported by press shoes (8,9) at the nips, for the web (2) to pass through. The rollers are heated to different temperatures, to give different heat levels at the nips for the web. The first roller (3) is heated to a temperature of 150-250 degrees C, and the second roller (4) is kept cool at a temperature level of 30-50 degrees C.
