Abstract
A paper or board machine has a fabric () that is adapted mobile as well as rolls (') arranged to support the fabric (). The fabric () is tensioned by changing the position of one roll (′) of the rolls (′). Correspondingly, the fabric () is guided by changing the alignment of one roll (′) of the said rolls (′). Surprisingly the fabric () is both tensioned and guided by changing the alignment and position of only one and the same roll (′). In addition, the wrap angle of the fabric () at this roll (′) is set higher than 30°.
