Paper forming apparatus
Abstract
Abstract 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.
