PROBLEM TO BE SOLVED: To reduce the tension of a web in the clearance between printing in the longitudinal direction. SOLUTION: The logical output correcting device for a printing machine includes a rotating body structure having a leg part and head part alternately arranged adjacent to each other along a longitudinal shaft. The leg part and the head part form a waveform surface for transforming the web to be printed wound around the rotating body structure into a waveform orthogonal to the carrying direction of the web. The flow channels opened on the surface of the rotating body structure are formed in the rotating body structure. The rotating body structure is provided with fluid communicating channels connected to the flow channels for guiding a pressurized fluid into the flow channels, then onto the surface of the rotating body structure.
