ABSTRACT:
An apparatus is disclosed for drying a web of paper emerging from a press section of a papermaking machine. The apparatus includes a first dryer section for transferring the web from the press section to the first dryer section. A second dryer section is disposed downstream relative to the first dryer section for initiating the drying of a second side of the web. A first dryer transfer means transfers the web without open draw between the first and the second dryer sections. The first dryer transfer includes a downstream vacuum roll, a downstream felt roll and a felt extending between the downstream vacuum roll and the downstream felt roll such that the web is conveyed and disposed between the felt and the second dryer section. The second dryer section includes an upstream vacuum roll and an upstream felt roll and a further felt extending between the upstream felt roll and vacuum roll such that the felt and further felt define therebetween a first dryer transfer section for transferring the web without open draw, the first dryer transfer permitting both threading of the web without the assistance of threading ropes and the drying of both sides of the web.
