B57692977 ABSTRACT OF THE DISCLOSURE A single tier dryer section apparatus is disclosed for drying a web extending through a paper machine. The apparatus includes a first dryer and a dryer felt extending around the first dryer such that the web is disposed between the felt and the first dryer for drying the web. A vacuum transfer roll is disposed downstream relative to the first dryer such that the web and felt extend contiguously from the first dryer to and around the transfer roll so that the felt is disposed between the web and the roll during transit of the web and felt around the roll. A second dryer is disposed downstream relative to the transfer roll such that the web and the felt extend contiguously from the transfer roll to and around the second dryer so that the web is disposed between the felt and the second dryer during transit of the web and the felt around the second dryer. The transfer roll includes a perforate shell such that when the roll is connected to a source of partial vacuum, a partial vacuum is generated within the shell for urging the web into close conformity with the felt and towards the perforate shell. The transfer roll is also movable from a first location to a second location. The first location is closely adjacent to the dryers so that the partial vacuum urges the web into conformity with the felt for inhibiting fluttering of the web. The second location is farther away from the dryers than the first location so that damage to the first dryer and the roll in the event of the web wrapping around the first dryer is inhibited.
