Abstract[English]
The present invention relates to a tissue paper machine (100) comprising - a forming section (101), - a drying section (102) comprising a Yankee dryer (20) and a non-dewatering transfer nip formed (TN) between the Yankee dryer (20) and a press assembly (30) for transferring the paper web (W) from the structured fabric (10) to the Yankee dryer (20), - a structured fabric (10), wherein the transfer nip (TN) is an extended press nip, the press assembly (30) comprising a press shoe (31) and an actuator (60) configured to operate the press shoe (31) to form the transfer nip (TN), and wherein the actuator (60) is configured to generate a desired linear load in the transfer nip (TN) by operating the press shoe (31) to extend into the transfer nip (TN) with a desired pressure and to change the linear load during operation of the tissue paper machine (100).[French]
La présente invention concerne une machine à papier ouaté (100) comprenant : une section de formage (101) ; une section de séchage (102) comprenant un sécheur frictionneur (20) et une ligne de contact de transfert (TN) non déshydratante formée entre le sécheur frictionneur (20) et un ensemble presse (30) pour transférer la bande de papier (W) du tissu structuré (10) au sécheur frictionneur (20) ; et un tissu structuré (10). La ligne de contact de transfert (TN) est une ligne de contact de presse étendue, l'ensemble presse (30) comprend un sabot de presse (31) et un actionneur (60) conçu pour faire fonctionner le sabot de presse (31) afin de former la ligne de contact de transfert (TN), et l'actionneur (60) est conçu pour générer une charge linéaire souhaitée dans la ligne de contact de transfert (TN) en actionnant le sabot de presse (31) pour qu’il s'étendre dans la ligne de contact de transfert (TN) avec une pression souhaitée et pour modifier la charge linéaire pendant le fonctionnement de la machine à papier ouaté (100).
