Abstrakti

Method of producing at least two different paper webs on one paper machine. According to the method during a first period of time, a first paper grade is produced and during a second period of time, a second paper grade is produced, said paper grades differing from each other with respect to their distribution of filler in direction Z. According to the invention, a filler-containing pigment slurry is applied on a wet paper web before drying and the feeding point of the pigment slurry is selected based on the desired distribution of the filler. By means of the invention, a change of quality can be achieved by changing the application point of the pigment particle suspension during the run, which provides for fast change of quality and small loss of material.
