The invention relates to a method of producing a structured fibrous web of paper suitable for tissue products. The method comprises forming a fibrous web and conveying the formed fibrous web on a water receiving felt () to a dewatering nip. An endless steel belt () with a smooth steel surface is passed through the nip together with the fibrous web and the water receiving felt () wherein the endless steel belt is heated by heaters (HE, HE). After the dewatering nip, the fibrous web is conveyed by the endless steel belt () to an endless textured fabric () which is permeable to air and to which the web is transferred from the endless steel belt () in a transfer nip. The textured fabric () runs at a lower speed than the endless belt (). After the transfer to the textured fabric (), the fibrous web is carried by the textured fabric () to a drying cylinder (). The transfer nip is formed by two rolls of which one is a suction roll within the loop of the textured fabric. The transfer nip has a length which is 5 mm-40 mm. The endless steel belt () has a width that exceeds the width of the textured fabric (). The invention also relates to a corresponding machine.

Method and a machine for producing a tissue web

This invention relates to a device and method of reducing the azimuthal torque acting on a pulling pod unit or azimuth thruster () having a rotary pod housing () with a substantially vertical slewing axis () and a fixed downwardly directed first fin () carried by the pod housing () abaft the slewing axis (), wherein said first fin is in the form of an elongated strip-shaped vane () and extends abaft the slewing axis () along the pod housing () to the vicinity of a rear end () thereof.
