ABSTRACT:
A transfer apparatus is disclosed for transferring a web from an upstream dryer to a downstream dryer of a dryer section. The apparatus includes a first dryer felt which extends around the upstream dryer for supporting the web such that the web is disposed between the first felt and the upstream dryer for drying a first side of the web. The first felt roll is disposed downstream relative to the upstream dryer for guiding the first felt such that the first felt diverges relative to the upstream dryer and extends from the upstream dryer to and around the first felt roll. A second felt roll is disposed between the upstream dryer and the first felt roll such that the web is disposed between the second felt roll and the first felt. A second dryer felt extends around the downstream dryer for supporting the web such that the web is disposed between the second dryer felt and the downstream dryer for drying a second side of the web. The second felt passes around the second felt roll and extends from the second felt roll to and around the downstream dryer such that the first and the second felts define therebetween a web transfer section, the web being sandwiched between the first and the second felts between the second and the first felt rolls. A device is provided for positively transferring the web from the first felt to the second felt when the first felt diverges relative to the second felt.
