Abstract (en)
[origin: US5401363A] A method of manufacturing a web of fibers, especially a web of paper. The pulp is uniformly distributed through an outlet over the width of the machine and along a wire or between two wires. Most of the moisture is subsequently extracted from the pulp accommodated on or between the wires at a draining point. Various amounts of retaining agents are added to the pulp at sections across the headbox and the web in order to control the level of retention sectionally.
