    Abstract: WEB PICK-UP ARRANGEMENT FOR FOURDRINIER TYPE PAPER MAKING MACHINE, PARTICULARLY ADAPTED TO PICK-UP NEWLY FORMED HEAVY WEIGHT WEBS FROM THE FORMING WIRE AND TO TRANSFEWR THE WEBS DIRECTLY TO THE PRESS FELT WITHOUT THE USE OF A PICK-UP FELT OR FABRIC. THE PICK-UP INCLUDES A PICK-UP ROLL, WHICH MAYH BE A PLAIN SURFACED ROLL AND HAS NIP PRESSURE COOPERATION WITH WIRE AS THE WIRE PASSES ABOUT A RETURN ROLL INTO ITS RETURN RUN FOR CLEANING. THE PRESS FELT IS MAINTAINED IN PRESSURE COOPERATION WITH THE PICK-UP ROLL BY A TRANSFER DEVICE ABOUT WHICH THE PRESS TURNS TO ITS UPWARDLY FACING PRESS RUN. THE TRANSFER DEVICE INCLUDES AN IDLER ROLL DISPOSED BENEATH AND REARWARDLY OF THE PICK-UP ROLL AND A SUCTION ROLL OR SUCTION BOX DISPOSED ON THE UNDERSIDE OF THE PRESS FELT EITHER AT THE POINT OF NIP ENGAGEMENT OF THE PRESS FELT TO THE PICK-UP ROLL OR ON THE OUTGOING SIDE OF THE PICK-UP ROLL.

    Abstract: ADJUSTABLE SUPPORT FOR SLICE LIP FOR PRESSURE HEAD BOX FOR PAPERMAKING MACHINE IN WHICH THE SLICE LIP HAS A TIP EXTENDING ACROSS THE BREAST ROLL AND FOURDRINIER WIRE ON THE ROLL. A BEAM IS SUPPORTED ON STATIONARY SUPPORTS INDEPENDENTLY OF THE HEAD BOX TO EXTEND ACROSS THE BREAST ROLL IN VERTICALLY SPACED RELATION WITH RESPECT TO THE BREAST ROLL AND FOR VERTICAL ADJUSTMENT RELATIVE TO THE BREAST ROLL. SUSPENSION LINKS SUSPEND THE SLICE LIP FROM THE BEAM. THE SUPPORT FOR THE BEAM COMPRISES ADJUSTABLE SUPPORT LEGS TO WHICH THE BEAM IS CONNECTED, THE SUPPORT LEGS HAVING AT THE BOTTOM ENDS ARCUATE SHAPED END MEMBERS WHICH ARE SUPPORTED BY AND ROCKABLE ON BEARING BLOCKS WHICH ARE IN TURN SUPPORTED BY SECURED BLOCK SUPPORTS. THE ARCUATE SHAPED END MEMBERS OF THE SUPPORT LEGS ARE SUP-

    PORTED ON THE BEARING BLOCKS COINCIDENT WITH THE POINT OF INTERSECTION OF EXTENDED RADIAL LINES EXTENDING FROM THE AXIS OF ROTATION OF THE BREAST ROLL THROUGH THE TIP OF THE SLICE LIP. THE POSITION OF THE SLICE LIP MAY THUS BE ADJUSTED WITH RESPECT TO THE PERIPHERY OF THE BREAST ROLL ALONG THIS RADIAL LINE TO MAINTAIN THE TIP OF THE SLICE LIP IN THE SAME FIXED RELATION WITH RESPECT TO THE BREAST ROLL, REGARDLESS OF UPWARD DEFLECTION OF THE SLICE LIP BY THE UPWARD FORCES OF THE STOCK OF THE LIP.

    Abstract: A curved foil member is positioned above the paper web extending transversely across the width of the web and is adjustably supported. A shower head is mounted on the foil support to clean the leading edge of the foil member. The foil member squeezes the web from above and forces air which has been entrained immediately above the path of the moving web down through the web to create a dewatering force.
