1. A tissue paper making machine (1) comprising:
a forming section (2) having a forming roll (4), a head box (5), a first forming fabric (6) and a second forming fabric (7);
a Yankee drying cylinder (3) mounted to be rotatable about a first axis of rotation (A1); and
a press roll (9) arranged inside the loop of the first forming fabric (6) and forming a nip (N) against the Yankee drying cylinder (3),
wherein:
the forming roll (4) is mounted to be rotatable about a second axis of rotation (A2), which second axis of rotation (A2) is parallel to the first axis of rotation (A1),
the head box (5) is arranged to inject stock into a gap (8) between the first forming fabric (6) and the second forming fabric (7),
the first forming fabric (6) is a water-absorbing felt that forms a loop and which is arranged to be capable of carrying a newly formed fibrous web (W) from the forming section (2) to the Yankee drying cylinder (3),
the distance (X) in the horizontal direction between the first axis of rotation (A1) and the second axis of rotation (A2) is in the range of equal to or greater than 20.0 m and less than or equal to 40.0 m, such that the distance (X) is configured to accommodate another component without having to move said first axis of rotation (A1) and said second axis of rotation (A2).
