Abstract
A novel sheet transfer stabilizer is provided for transferring a fibrous wet sheet from a press section to a dryer section of a paper-making machine by way of a felt. The sheet transfer stabilizer includes a composite Venturi box which is disposed between a felt roll of the press section and a first dryer. The Venturi box includes three side-by-side Venturis, an inlet Venturi, an outlet Venturi, and a main Venturi. Such Venturi boxes are used to create and maintain a vacuum in the felt/web system.
