APPARATUS AND METHOD FOR MANUFACTURING PAPER OR BOARD AND THUS MANUFACTURED PAPER OR BOARD

摘要

The invention relates to a paper/board manufacturing method, in which a paper/board web is re-moistened at some point between wet pressing (I) and rewinding (VI), and to an apparatus for implementing the method. In the method, prior to re-moistening, a paper/board web is calendered and/or dried in at least one operation (III) with a metal-belt calender type processing assembly (1), comprising a metal belt (2) adapted to travel around at least one guide element (3), outside said belt being provided at least one counter-element (5) creating a contact surface with the belt, such that between the belt and the counter-element is established a web processing zone (N), the web to be processed being passed therethrough. In the processing assembly, the processing zone length is adjustable by way of arranging the belt guide element and/or shaping the counter-element. Downstream of re-moistening (IV), the paper/board web is subjected to final calendering (V) with a desired calendering technique.
