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 or fabric. The sheet transfer stabilizer includes a composite Venturi box which is disposed between a felt or fabric roll of the press section and a first dryer. The Venturi box includes three side-by-side Venturis, namely an inlet Venturi, an outlet Venturi, and a main Venturi. Such Venturi boxes are used to create and maintain a vacuum in the felt or fabric web system. In addition, a novel method is provided for guiding a wet fibrous web from a press section to a drying section of a paper-making machine. The method includes the steps of passing the wet fibrous web from the press section in an open draw onto a felt or fabric, the felt or fabric passing about a guide roll. The wet fibrous web and the felt or fabric, are urged against each other as a drying wire of the drying section passes from the guide roll to a drying cylinder by the generation of negative pressure in the space on the side of the felt or fabric, which is opposite to the side of the felt or fabric, which supports the fibrous web. The negative pressure is generated using the combination of an inlet Venturi, having an inlet opening and a throat, the inlet Venturi being located adjacent to the guide roll in order to draw up and exhaust air from an area where the paper web separates from the surface of the guide roll, or an outlet Venturi having an inlet opening and a throat, the outlet Venturi being situated adjacent to the drying cylinder to draw away air from a gap between the dryer cylinder and the inlet opening of the outlet Venturi; or a main Venturi having a first and second inlet openings and throat, the main Venturi being disposed between the inlet Venturi and the outlet Venturi to draw away air away from, and to maintain a negative static pressure over, an unsupported span between the guide roll and the dryer cylinder.
