<p>In order to reduce the adverse effects of overpressure on a paper sheet existing at the outer face of a dryer fabric moving in contact with a dryer cylinder in the dryer section of a paper machine, it is proposed to provide void-spaces at the fabric-cylinder interface, or the equivalent, arranged in fluid flow connection with that space in which boundary air moving with the fabric towards the position of engagement of the fabric with the cylinder is progressively compressed, as the fabric moves into contact with the cylinder.</p> |
