Abstract
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°. The invention also relates to a method of operating the machine.
