    Abstract: The invention relates to a method of making a paper or paper board, in which method cut pulp is prepared by cut-ting basic cellulosic fiber pulp at the consistency of at least 25 % so that the average fiber length of the basic pulp is decreased by more than 25 % and the SR number of the cut pulp is at most 20 % higher than that of the basic pulp, and the cut pulp is used as a raw material in the preparation of a stock.

    Abstract: An in-line web material processing machine (1) for producing a coated material is disclosed. The processing machine comprises a process vacuum chamber (31) housing an unwinder reel holder for holding a first supply roll (51) of web material (2) to be processed and a vacuum coating unit (52) for deposing a coating on the web material. A loading vacuum chamber (32) housing a second supply roll of web material to be processed is provided, with an inlet closure (321) arranged between the process vacuum chamber (31) and the loading vacuum chamber (32). The inlet closure (321) is arranged to be moved between a closed state, in which the vacuum chambers are separated from each other, and an open state, in which access is provided between the vacuum chambers. An automatic reel change system (4) is operable to move the second supply roll of web material from the loading vacuum chamber (32) to the process vacuum chamber (31) under vacuum when the inlet closure (321) is in the open state and to change a supply roll (51) on the unwinder reel holder from the first supply roll to the second supply roll under vacuum.
