Abstract (en)
A paper machine for stable high-speed papermaking without slackness of wet web, the paper machine including the most downstream (20 and 21) one of the press units (14 and 15, 20 and 21) along the transfer path of the wet web in the press part (Y), and the most upstream one (25a) of the dryer units (25a-25d) and the second upstream dryer (25b) unit of the dryer units (25a-25d) along the transfer path of the wet web in the dryer part (Z) are associated with three different belt mechanisms, respectively, so that the driving units of the three driving units associated with the most downstream press unit (20 and 21) and the first (25a) and second (25b) upstream dryer units are individually controlled so that a transfer speed (V0, V1, V2) of the wet web along each of the most downstream press unit (20 and 21) and the first (25a) and second (25b) upstream dryer units is individually set. <IMAGE>
