Abstract (en)
[origin: EP0859081A2] The press assembly, to extract water from a fibre web and/or polish or change its surface structure, has at least two successive press zones. A characteristic value (K) of the press action is determined of at least 2.5 kPa/sec/m through the product of the length (L1) of the first press zone in the direction of web travel and the total press pulse (Iges).
