Title:
【発明の名称】紙ウェブのドライヤ
Document Type and Number:
Japanese Patent JPH10502712
Kind Code:
A
Abstract:
A paper drying section utilizes two reversing rolls between each dryer roll to extend the available time for vapor to flash from the web. A vacuum box is disposed between the two reversing rolls to support and dry the felt and paper web as it passes from one reversing roll to another. An air cap is used to blow high velocity air onto the exposed surface of the paper web which is held by the vacuum box. The spacing of the two reversing rolls increases the wrap of the single tier dryer by approximately twenty percent over that of a conventional single tier dryer with a single reversing roll. Another configuration dryer section positions the first of the two reversing rolls downwardly beneath its adjacent dryer roll creating a long draw between the dryer roll and the first reversing roll. This long draw is supported by a vacuum box adjacent the felt. The downward positioning of the first roll increases the length of the draw between the first and second reversing rolls, providing additional area for drying by an air cap.
