Twin wire paper making method in which controlled dewatering in tapering gap causes suspension to move at speed of wires

Claim 1

A PAPER MAKING METHOD IN WHICH AT LEAST 30% OF THE FORMING OF A CONTINUOUS SHEET IS EFFECTED BY DEWATERING A FIBER SUSPENSION IN A TAPERED GAP DEFINED BY A PAIR OF TRAVELING WIRES, THE METHOD COMPRISING THE STEPS OF A. ESTABLICHING AND MAINTAINING, IN A REGION ADJACENT THE GAP INLET, A VOLUME OF FIBER SUSPENSION WHICH IS UNDER PRESSURE, HAS UNIFORM CONSISTENCY, AND IS IN A TURBULENT STATE, B. SAID PRESSURE BEING SUCH AS TO CAUSE SUSPENSION TO FLOW INTO THE GAP AT THE SPEED OF THE WIRES; C. CAUSING THE WIRES TO PASS IN CONTACT WITH SUSPENSION IN SAID REGION IMMEDIATELY BEFORE THEY DEFINE SAID GAP; D. WITHDRAWING LIQUID FROM THE SUSPENSION IN SAID REGION THROUGH EACH WIRE BY SUCTION TO THEREBY CAUSE DEPOSITION OF FIBERS ON THE WIRES AND EFFECT PARTIAL FORMATION OF THE SHEET; E. WITHDRAWING LIQUID FROM THE SUSPENSION IN THE GAP THROUGH EACH OF THE WIRES BY SUCTION APPLIED IN EACH OF A SERIES OF SEPARATE ZONES POSITIONED ALONG THE PATH OF TRAVEL OF THE WIRE, WHEREBY THE CONSISTENCY OF THE SUSPENSION INCREASES GRADUALLY AS THE SUSPENSION TRAVELS THROUGH
