Abstract (en)
[origin: EP0732446A1] The calender assembly, to process both sides of a paper web, has a stack of six to eight rollers (2-9) with an alternating gap (16) between two soft rollers, or there are two identical roller stacks each with three to five rollers. For ≥ 1 working roller gap (15), the gap width is set to give a paper dwell time of ≥ 0.1 ms. The heating of a roller (2,4,7,9), flanking a working roller gap, gives a roller surface temp. of ≥ 100 degrees C. The mean pressure applied by the rollers in the working gap is >42 N/mm<2>.
