ABSTRACT:
A transfer apparatus is disclosed for transferring a web from a press section to a first dryer of a dryer section. The apparatus includes a lead-in roll which is disposed closely adjacent to the press section. A felt extends around the lead-in roll and from the lead-in roll to the first dryer such that the web extends in an "open draw" from the press section to the lead-in roll and is thereafter supported by and beneath the felt towards a dryer nip defined between the felt and the first dryer. A vacuum generating device is disposed adjacent to the dryer nip such that the web and the felt are disposed between the vacuum generating device and the first dryer. The web is disposed between the felt and the first dryer, and the vacuum generating device induces a partial vacuum in the vicinity of the nip so that wrinkling and breakage of the web as the web approaches the nip is inhibited.
