A paper or board machine has a fabric ( 10 ) that is adapted mobile as well as rolls ( 11, 11 ') arranged to support the fabric ( 10 ). The fabric ( 10 ) is tensioned by changing the position of one roll ( 11 ') of the rolls ( 11, 11 '). Correspondingly, the fabric ( 10 ) is guided by changing the alignment of one roll ( 11 ') of the said rolls ( 11, 11 '). Surprisingly the fabric ( 10 ) is both tensioned and guided by changing the alignment and position of only one and the same roll ( 11 '). In addition, the wrap angle of the fabric ( 10 ) at this roll ( 11 ') is set higher than 30°.
