Abstract
Press section of a machine for producing a fibrous web and process for pressing a fibrous web. The press section may include at least two shoe press units including at least one press shoe and a revolving flexible press belt, a counterpart face, at least two nips having a length extended in a web travel direction and formed by each at least one press shoe pressing the revolving flexible press belt against the counterpart face. A length of the extended nip may be at least substantially the same as a length of the at least press shoe length, measured in the web travel direction, forming the extended nip and at least one of the shoe press units having press shoe length different from the other shoe press units, whereby various extended nip length are formed. The process may include positioning a first of the at least two nips upstream, with respect to the web travel direction, a last of the at least two nips, wherein one of the first and last nips has a nip length greater than the other and applying different pressing forces in the at least two nips such that the one of the first and last nip having a greater length has a lesser pressing force applied.
