A tissue machine () has a Yankee () and a shoe roll () that forms a nip with the Yankee (). The nip has a maximum extension from an entry point () to an exit point (). A flexible belt () forms an outer circumference of the roll (). A fabric () carries a fibrous web (W) to the nip and passes through the nip with the web. The fabric () reaches the circumference of the roll () at a first contact point () and wraps the roll () from the first contact point to the nip. A mechanical support () inside the belt () supports the belt () between the first contact point () and the nip. The fabric () wraps the roll () from the first contact point () by more than 80&#xb0;. The invention also relates to a method of operating the machine.

Tissue paper making machine and a method of operating a tissue paper making machine

A method of making tissue paper is provided, in which a fibrous web is formed in a forming section and transferred to a Yankee drying cylinder in a non-dewatering transfer nip formed between the Yankee drying cylinder and a shoe roll. The shoe roll has a shoe that is deformable such that it can adapt to a cylindrical outer surface of the Yankee drying cylinder, and a rotatable flexible jacket arranged to run in a loop around the shoe. A structured carrier fabric runs around the shoe roll and has land areas and void areas facing the fibrous web. The length of the transfer nip is in the range of 30 mm -100 mm and the linear load in the transfer nip is in the range of 35 kN/m-120 kN/m. The peak pressure in the transfer nip lies in the range 2 MPa-8 MPa.
