| 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.

| THIS RELATES TO AN IMPROVED VERSATILE AND STURDY PAPERMAKING MACHINE STRUCTURE. THE INSTANT MACHINE INVOLVES THE SELECTIVE USE OF A PICKUP ARRANGEMENT USING A DURABLE POROUS PICKUP BELT THAT IS NOT REQUIRED TO TRAVEL THROUGH A PRESS NIP AND THUS AVOIDS WEAR INCIDENTAL TO CONVENTIONAL FELT WASHING AND RECONDITIONING DEVICES. ALSO, THE PRESENT ARRANGEMENT PROVIDES FOR THE USE OF A SIMPLIFIED FIRST PRESS FOR ONLY A SINGLE FELT WITH THE WEB THEREON WHICH AFFORDS BETTER INITIAL DEWATERING, AND AVOIDANCE OF THE CONVENTIONAL TRANSFER (TWO FELT) PRESS, USING A SYSTEM WHICH EMPLOYS STANDARD PARTS SO ARRANGED AS TO AFFORD BEST ACCESS FOR MAINTENANCE.

| THIS RELATES TO THE TRANSFER OF A MOIST PAPER WEB FROM ONE POROUS BELT TO ANOTHER, SPECIFICALLY, FROM A PAPER MACHINE FORMING WIRE TO A PICK-UP FELT. THIS IS DONE BY URGING A PICK-UP FELT (WRAPPING A PICK-UP ROLL) INTO CONTACT WITH THE WEB ON THE WIRE UNDER PRESS NIP CONDITIONS WHICH ARE AFFORDED BY THE USE OF A GROOVED PRESS ROLL BACKING THE FORMING WIRE AT THE WEB PICKUP. IN ORDER TO OBTAIN THE MOST FAVORABLE CONDITIONS FOR APPLYING NIP PRESSURE AND THEN CARRYING THE WEB AWAY FROM THE WIRE ON THE PICK-UP FELT THE GROOVED ROLL USED HAS A RELATIVELY SMALL RADIUS (AND MAY BE CROWNED TO KEEP THE WIRE SPREAD).
