Roller cassette for semi-rotary machines, which can be inserted into offset printing units. The invention relates to a roller cassette for semi-rotary machines, which can be inserted into offset printing units. The invention comprises at least three rollers, namely: at least one printing plate roller in the form of a first roller, one transfer roller in the form of a second roller and a printing cylinder or counter-cylinder in the form of a third roller. The invention is characterised in that the printing rollers (3) in the cassette are disposed in a semi-rotary configuration, with the second and third rollers being disposed in the same vertical plane or with a slight inclination in relation to said plane and the first roller being disposed in a tangential plane or inclined in relation to the plane of the second and third rollers. In this way, when the cassette is inserted into a printing unit (2) that is designed to receive roller cassettes, said unit can print with the specific printing characteristics of the semi-rotary rollers (3).
