An apparatus and a method in which when both of two-stage type and impression cylinder connecting type sheet-fed perfecting multi-color printing presses are manufactured, there is no need for a manufacture of extra parts or an extra stock, and also the replacement and servicing of parts are easy in the event of a failure of a printing unit or the sheet-fed perfecting multi-color printing press. For this purpose, modules for the printing unit for the sheet-fed perfecting multi-color printing press, each of which consists of a combination of at least two elements of a group consisting of an intermediate cylinder, impression cylinder, blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism are manufactured, and the modules are used to manufacture the two-stage type and impression cylinder connecting type sheet-fed perfecting multi-color printing presses.

Module for sheet-fed perfecting multi-color printing press, printing unit and sheet-fed perfecting multi-color printing press, and manufacturing methods therefor

An intermediate cylinder comprising a main body, and a plurality of suction boxes formed in the main body at positions different with respect to a rotation axis of the main body. The intermediate cylinder further comprises a plurality of suction bores formed in the suction boxes so that they are open at an outer peripheral surface of the main body, an air suction source for generating suction force within the suction boxes, and a switching means for selectively switching connections between the plurality of suction boxes and the air suction source.
