Apparatus for transferring a web from the forming section to the press section in a papermaking machine
Abstract
Abstract Apparatus for transferring a wet paper web from the downstream end of a Fourdrinier wire to a press section comprises a suction transfer roll that runs within an endless, open-mesh transfer fabric and picks the web off the Fourdrier wire. The web is transferred from the transfer fabric onto a horizontal or inclined run of a carrier belt which is led in closely adjacent the wire section of the machine and into proximity with the transfer roll. The carrier rolls for the transfer fabric are arranged to guide the transfer fabric along a path conjoint with a portion of the run of the carrier belt at a location intermediate the transfer roll and the first press of the machine press section. At a location along the conjoint run of the carrier belt and the transfer fabric, a suction box creates a differential pressure across the web to transfer it from the transfer fabric onto the carrier belt so that it runs with the carrier belt to the press section.
