[origin: US6221214B1] A wet section of a machine for producing a fibrous material web that includes at least one press. The press includes a nip through which the fibrous material web is guided. The fibrous material web is preformed in a web forming zone. At least one press is an elongated nip press that is elongated in direction of the web travel. This nip is positioned in a region where the dry matter content of the preformed fibrous material web that comes into the nip is less than or equal to about 15% and, preferably is less than or equal to about 12%. A method for treating a fibrous material web in a wet section of a machine for producing the fibrous material web. The wet section includes at least one press including an elongated nip, at least one press and the elongated nip are elongated in a web travel direction. Further, the elongated nip is positioned in a region of the machine where the dry matter content of the fibrous material web, as it enters the elongated nip, is less than or equal to about 15%. The method includes preforming the fibrous material web in a forming section of the machine, guiding the fibrous material web to the at least one elongated nip, and pressing the fibrous material web in the at least one elongated nip elongated nip.
