Abstract
The invention relates to a tissue paper making machine designed for possible rebuild from one concept to another. The machine comprises a forming section () and a Yankee drying cylinder () mounted to be rotatable about a first axis of rotation (A). The forming section has a forming roll mounted for rotation about a second axis of rotation (A) which is parallel to the first axis of rotation (A). The forming section () has a head box () and a first and a second forming fabric (). The head box () is arranged to inject stock into a gap () between the first forming fabric () and the second forming fabric (). The first forming fabric () is a felt that forms a loop and is arranged to carry a newly formed fibrous web (W) from the forming section () to the Yankee drying cylinder (). The tissue paper making machine () comprises a press roll () arranged inside the loop of the first forming fabric () and forming a nip (N) against the Yankee drying cylinder (). The distance (X) in the horizontal direction between the first axis of rotation (A) and the second axis of rotation (A) is in the range of 18 m-40 m.
