The machine has a transfer drum (2) e.g. suction drum, arranged between frame walls, and serving for transporting a print sheet. The walls are spaced at a distance from each other. The drum includes an end with a rotationally-rigid axle pin (11), and another end with a rotatable shaft pin (12) along a rotational axis (9). The drum includes an outer pipe (14), which is arranged coaxial to an inner pipe (13). The outer pipe is rotatably mounted on the inner pipe. The axle pin is arranged at the inner pipe. The shaft pin is connected with the outer pipe.
