The apparatus includes a backing roll and a press member which cooperates with the backing roll for defining therebetween the press nip. A press blanket extends through the press nip such that the web is disposed between the blanket and the backing roll during passage of the web through the press nip. A backing drum is disposed downstream relative to the press nip such that the blanket and the web extend contiguously relative to each other from the press nip to the backing drum. A dryer felt cooperates with the backing drum such that the web is disposed between the blanket and the felt during passage of the blanket, web and felt around the backing drum and a transfer mechanism is disposed adjacent to the backing drum for transferring the web without an open draw from the blanket to the felt such that the web follows the felt through the dryer section. A method for transferring the web from the press nip to the dryer section is also disclosed.Field of SearchRunning or indefinite length work forming and/or treating processes (e.g., web)Means removing web product from molding surface Blow off acting through mold Molds with subsequent separate pressing means Pressure Lead strip forming and/or guiding Gas or vapor circulation for contact with treated material With belts or felts | |
