Abstract: A roll for supporting a moving web includes a helical spring covered by a flexible outer shell to provide for curvature of the roll which may be preset to compensate for deflections of the roll. The roll has an inner core or shaft construction which includes an elongate shaft extending through a plurality of spaced-apart annular flanges each of which includes a groove at the same lead angle as the lead angle of the helical spring for threadedly engaging the turns of the spring and aiding in fabrication of the roll. The shaft may be supported in an antideflection mode of operation by securing the end thereof for rotation in spherical bearings and providing means at the distal ends of the shaft for imparting a selected deflection to the shaft. The roll may also be configured as a bowed roll by providing a nonrotational fulcrum for the shaft at each end of the roll and by providing means at each distal end of the roll for imparting bowing forces to the roll. In this configuration, the flanges which connect the shaft to the flexible portion of the roll are provided as bearings with the central portions of flanges forming a bearing race to be secured to the shaft and the outer portions of the flange forming an outer bearing race for threaded engagement with the helical spring. As a bowed roll the apparatus is further provided with means for adjusting the supporting apparatus of the roll for varying the plane of deflection.

Abstract: THE SURFACE OF A PAPER FORMING WIRE OPPOSITE THE PAPERMAKING STOCK CARRIED THEREBY RUNS IN CONTACT WITH A PORTION OF AN ENDLESS MOVING DRAINAGE BELT PROVIDED WITH ENCLOSED POCKETS WHICH HAVE OPENINGS FACING AN ADJACENT WIRE TO COLLECT WATER DRAINED FROM THE STOCK THROUGH THE ADJACENT WIRE AND WHICH ARE SUBSEQUENTLY EMPTIED BY GRAVITY ALONG A PORTION OF THE BELT PATH REMOTE FROM THE WIRE. SUCH APPARATUS IS PARTICULARLY SUITABLE FOR USE IN TWIN WIRE VERTICAL FORMATION MACHINES IN WHICH A SEPARATE DRAINAGE BELT IS PROVIDED IN CONTACT WITH EACH FORMING WIRE IN CLOSE PROXIMITY TO THE HEADBOX SLICE.

Abstract: A STOCK SUPPLY AND DISTRIBUTION SYSTEM FOR THE HEADBOX OR STOCK INLET BOX OF A PAPERMAKING MACHINE INCLUDING A STOCK SUPPLY HEADER WHICH EXTENDS AND WHICH IS INTERNALLY COMPARTMENTALIZED ACROSS THE WIDTH OF THE HEADBOX, AND PLURAL GROUPS OF NARROW RISERS WHICH COMMUNICATE RESPECTIVELY THE VARIOUS COMPARTMENTS OF THE STOCK SUPPLY HEADER WITH THE STOCK INLET BOX. A BLOCK VALVE IS PROVIDED FOR SELECTVIELY SHUTTING OFF FLOW THROUGH ANY OF THE GROUPS OF RISERS THEREBY REDUCING THE TOTAL STOCK FLOW RATE WHILE MAINTAINING A SUBSTANTIALLY CONSTANT RATE OF FLOW THROUGH THE OPENING FLOWING COMPARTMENTS AND RISERS.

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: THE INVENTION IS DIRECTED TO A HEADBOX FOR A PAPER MAKING MACHINE WHICH INCLUDES A PLURALITY OF STOCK RECEIVING CHAMBERS FOR DELIVERING DISCRETE STOCK STREAMS TO A CONTINUOUS MOVING FORMING SURFACE. THE CHAMBERS ARE FORMED IN A COMMON STRUCTURE AND SEPARATED ONE FROM THE OTHER BY WALL MEMBERS. EACH OF THE WALL MEMBERS HAS ENDS TERMINATING ADJACENT THE FORMING SURFACE AND THE ENDS OF A CORRESPONDING PAIR OF WALL MEMBERS CONSTITUTE THE SLICE OPENING FOR THE CORRESPONDING CHAMBER. STOCK IS DELIEVERED TO THE FORMING SURFACE FROM EACH OF THE SLICE OPENINGS IN A LAYER BY LAYER FASHION WHEREBY THE STOCK FROM A SECOND SLICE OPENING IS LAID OVER THE STOCK FROM THE FIRST SLICE OPENING, AND THE SOCK FROM THE THIRD SLICE OPENING IS LAID OVER THE STOCK FROM THE SECOND SLICE OPENING.

Abstract: A tubular rectifier roll for use in a paper machine headbox is provided with tapered radial perforations of streamlined contour which impart essentially uniform and nonturbulent rectilinear flow to the paper stock emerging from the downstream side of the roll and entering the headbox slice, thereby insuring uniform deposition of the paper stock onto a paper-forming surface.
