摘要	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).
