Patent ID: 8048269

Claim:
A method of forming a fiber web comprising the steps of: feeding a pulp suspension jet of stock from a headbox in a travel direction on to an upper surface of a lower wire of a single-wire forming section; wherein the pulp suspension jet engages the upper surface of the lower wire at an impact point immediately after a breast roll and over a cover of at least one stationary first forming shoe, said impact point being between a leading edge and a trailing edge of said cover; non-pulsating dewatering a pulp suspension formed from the pulp suspension jet on the upper surface of the lower wire with an underpressure applied to the pulp suspension through a plurality of through holes defined by portions of the cover of the at least one first forming shoe, the dewatering starting at the impact point, the cover setting against an inner surface of the lower wire, wherein the through holes are openings or slots substantially in a longitudinal direction of the machine; wherein the non-pulsating dewatering of stock of the pulp suspension takes place over a straight portion of the cover of the at least one first forming shoe which is straight at the impact point and between the impact point and the trailing edge of the at least one stationary first forming shoe; and dewatering the stock with pulsating dewatering over a plurality of stationary cross-machine directional dewatering strips provided with slots therebetween, installed below the lower forming wire following the at least one first forming shoe.
