发明名称 Calender for calendering of a paper or of an equivalent web material
摘要 <p>The invention concerns a calender which comprises a variable-crown upper roll (13, 13a), a variable-crown lower roll (14, 14a), and two or more intermediate rolls (15...22, 15a...22a) fitted between the upper (13a, 13a) and lower (14, 14a) rolls, said rolls being arranged on the frame (11, 11a) of the calender as a substantially vertical stack of rolls (12, 12a) and said rolls (13...22, 13a...22a), placed one above the other, being in nip contact with one another. The natural deflection lines produced by the own gravity of the intermediate rolls (15...22, 15a...22a) are substantially equal.</p>
