The invention relates to a method of manufacturing a paper or board web, in which method the web is manufactured in an on-line manufacturing process, in which the web is passed from a paper or board machine (15) directly to a finishing device/finishing devices (60, 50, 10). In the method, the state of the finishing device/finishing devices (60, 50, 10) is monitored and, during a shutdown of a finishing device (60; 50; 10), said finishing device is bypassed, the web coming from the paper or board machine (15) is wound into machine reels and/or treated by means of some finishing device/finishing devices and wound into machine reels.

La présente invention concerne un procédé de fabrication d'une bande de papier ou de carton. Dans ce procédé, la bande est fabriquée selon un processus de fabrication en ligne dans lequel on fait passer la bande directement d'une machine (15) à papier ou à carton à un ou plusieurs dispositif(s) de finition (60, 50, 10). Dans ce procédé, on surveille l'état des dispositifs de finition (60, 50, 10) et, lors de l'arrêt d'un dispositif de finition (60, 50, 10), celui est dérivé. La bande sortant de la machine (15) à papier ou à carton est enroulée autour des bobines de la machine, et/ou traitée à l'aide d'un ou de plusieurs dispositif(s) de finition puis enroulée autour des bobines de la machine. En outre, cette invention concerne une machine à papier ou à carton, qui, associée à au moins un dispositif de finition, constitue un processus de fabrication en ligne.
