Abstract[English]
The present invention relates to a paper making machine, comprising a forming section (101) for forming a fibrous web (W) from stock injected from a head box into a forming nip (FN) and a drying section (102) The drying section comprises a structured fabric (10) transporting the fibrous web (W), a Yankee drying cylinder (20) and a press arrangement (30) arranged to form an extended press nip that is a transfer nip (TN) with the Yankee drying cylinder (20) where the fibrous web (W) is transferred from the structured fabric (10) to the Yankee drying cylinder (20). The press arrangement (30) comprises a press body (31) arranged to extend against the Yankee drying cylinder (20) into the transfer nip (TN) formed between the press body (31) and the Yankee drying cylinder (20), wherein the press arrangement (30) also comprises an actuator (32) for extending the press body (31) into the transfer nip (TN) in order to load the transfer nip (TN). The extension of the transfer nip (TN) in a machine direction (MD) is ≤ 20 mm.[French]
La présente invention concerne une machine de fabrication de papier, comprenant une section de formation (101) pour former une bande fibreuse (W) à partir d'une pâte injectée depuis une boîte de tête dans une ligne de contact de formage (FN) et une section de séchage (102). La section de séchage comprend un tissu structuré (10) transportant la bande fibreuse (W), un cylindre de séchage Yankee (20) et un agencement de presse (30) agencé pour former une ligne de contact de presse étendue qui est une ligne de contact de transfert (TN) avec le cylindre de séchage Yankee (20) où la bande fibreuse (W) est transférée du tissu structuré (10) au cylindre de séchage Yankee (20). L'agencement de presse (30) comprend un corps de presse (31) agencé pour s'étendre contre le cylindre de séchage Yankee (20) dans la ligne de contact de transfert (TN) formée entre le corps de presse (31) et le cylindre de séchage Yankee (20), l'agencement de presse (30) comprenant également un actionneur (32) pour étendre le corps de presse (31) dans la ligne de contact de transfert (TN) afin de charger la ligne de contact de transfert (TN). L'extension de la ligne de contact de transfert (TN) dans une direction machine (MD) est ≤ 20 mm.
