摘要： A rotor assembly for use in pulping apparatus is similar in general construction to the disclosure of Vokes U.S. Pat. No. 3,073,535, but the thickness of its defibering vanes is reduced to minimize their pumping action, and pumping vanes are provided on the outer surfaces of certain of the defibering vanes to increase the vortical circulation effect created by the rotor in operation.

摘要： Waste paper containing materials, e.g., commercial ''''waste paper'''' or municipal waste, are treated for recovery of reusable paper therefrom by slushing in a pulper followed by screening of the entire output extracted from the pulper, with or without an intermediate centrifugal cleaning operation, in a screen having fine perforations sized to accept only substantially fully defibered paper. The reject flow from this screen is maintained at an adequately high rate, e.g., 20-80% to assure freedom from blocking of the screen perforations. A deflaker is connected to receive this reject flow, and the output of the deflaker is separated by a tailing screen into accepts which are recycled to the primary screen and rejects which are eliminated from the system. Major advantages of this method and system include the use of only one piece of apparatus for each of the essential operations of pulping, screening and deflaking, the elimination of low specific gravity reject from the system at a single station, and distribution of power requirements in such manner that the ratio of pulping power to deflaking power is 1.5 or less.

摘要： High speed cutters are attached adjacent the outlet of a wire cage making machine to sever individual cages as they issue from the machine. Upon actuation, a positioning piston swings the jaws of each cutter into a cutting position around each longitudinal cage wire and simultaneously opens a control spool to admit hydraulic fluid to a power cutting piston to sever the wire. The pistons and jaws then quickly retract to avoid interference with the advancing wires of the next cage. A hoist neutralizes the weight of the cut cage while the wrap wires are cut, and a second hoist automatically transports and deposits the cage at a preselected location.

摘要： A die assembly for multiple layer extrusion onto a paper web substrate is movable on an overhead support beam from an on-line position over a laminating station to an off-line position transversely adjacent such station. A pair of stationary extruders feed plastic material to the die assembly through a pair of movable feed assemblies each of which includes two straight sections of conduit connected to each other by a rotary joint and connected to the extruder and to the die assembly by further rotary joints so that movement of the die assembly is enabled by a swinging and folding movement of the conduit sections. An improved die adapter is also disclosed for the simultaneous three-layer co-extrusion from the two extruders in which the film thicknesses of the outer layers are controlled with respect to the center layer.

摘要： In coating doctor apparatus in which an air doctor is used to remove coating from a freshly coated web trained about a backing roll, internal baffles are eliminated and the contours of the coating return chamber are designed using flow control principles so that strong vortices and attendant misting are avoided in the coating return chamber, while at the same time subambient pressures generated along the curved surfaces of the chamber cause strong entrainment of air through the spaces between the edges of the coating chamber and the backing roll and air doctor and prevent coating material from escaping from the coating system.

摘要： Screening and defibering apparatus which includes a chamber which is preferably, but not necessarily, rectangular in cross section, and which is subdivided into a central intake section and outwardly disposed outlet sections by a pair of spaced, parallel, foraminous walls. A slurry of the material to be treated is passed through an intake line into the intake section where it is subjected to mechanical and hydraulic shear forces by a pair of rotors, each of which is rotatably mounted in the intake section in closely spaced relationship to one of the foraminous walls. Accepted portions of the slurry pass through perforations in the foraminous walls into the outlet sections for removal through outlet lines while rejected material is bled from the intake chamber, either periodically or continuously, through a reject line. A rinse line may also be utilized, feeding into the intake chamber, to assist in purging the system.

摘要： An annular barking rotor has a hub portion rotatably supported by a concentric anti-friction bearing and supports a plurality of radially pivotable barking arms each biased by an air motor mounted on the rotor and connected to an annular air chamber within the rotor. Air is supplied to the chamber and motors through a set of sliding air shoes, and the pressure of the air is controlled by a series of pilot operated valves, relay exhaust valves and regulating valves actuated by controls located at a remote console. Pilot operated diaphragm exhaust valves are carried by the rotor for connecting the air chamber directly to atmosphere and are actuated by a pulse of pilot air supplied through another air shoe connected to the main air supply through a pilot operated valve controlled by a valve also located at the console.

摘要： A MACHINE FOR FORMING PAPER FROM STOCK BETWEEN A PAIR OF VERTICALLY TRAVELING SPACED FORMING WIRES WHICH EXTEND BETWEEN UPPER BREAST ROLLS TO LOWER COUCH ROLLS. THE WATER IS REMOVED FROM THE STOCK TO A DRAINAGE SYSTEM BY DEFLECTORS MOUNTED ON OPPOSITE SIDES OF THE FORMING ZONE IN CONTACT WITH THE WIRES WHICH CAUSE THE WIRES TO EXERT A SQUEEZING ACTION ON THE STOCK AND WHICH REMOVE WATER FROM THE REAR SIDE OF THE WIRES. THE DEFLECTORS ARE INDIVIDUALLY ADJUSTABLE SO THAT THE WIRE ENGAGING SURFACES MOVE HORIZONTALLY IN A PLANE PARALLEL TO THE WIRES WITHOUT ANY VERTICAL MOVEMENT. SEPARATE APPARATUS IS ALSO PROVIDED FOR ADJUSTING THE ANGULAR POSITION OF EACH WIRE ENGAGING SURFACE.

摘要： A PRESS SECTION HAS A DRIVEN SUCTION PRESS ROLL AND A SMALL DIAMETER PRESS ROLL LOCATED WITHIN AN ENDLESS FELT, AND EACH PRESS ROLL FORMS A NIP WITH THE SAME THIRD PRESS ROLL LOCATED OUTSIDE THE FELT. THE SMALL DIAMETER PRESS ROLL IS ROTATABLY SUPPORTED WITHIN A CRADLE FORMED BY A PLURALITY OF BACKUP ROLLERS WHICH ARE MOVEABLE TO RETRACT THE PRESS ROLL TO A POSITION WHERE IT IS DRIVEN SOLELY BY THE FELT AND PERMITS THREADING OF A PAPER WEB WITHOUT DAMAGING THE FELT.
