Claim 3:
4. The sheet-fed printing unit according to claim 3, characterized in that a fixing element of the at least one blower drum (712) has an inner contact surface and an outer contact surface, which are arranged so as to cooperate for clamping sheets (02), and the inner contact surface is at least partially located at a distance from an axis of rotation (719) of the at least one blower drum (712) which corresponds to the base radius (R0), and/or characterized in that at least one sheet guide device and at least one sheet blower device are assigned to the at least one blower drum (712), and the at least one sheet guide device has at least one inner surface, whose shape corresponds to a section of a cylinder shell having an axis that is identical to the axis of rotation (719) of the at least one blower drum (712), and the inner surface is located at a distance from the axis of rotation (719) of the at least one blower drum (712) which is larger than the base radius (R0), and/or characterized in that the at least one sheet blower device is used to generate a flow of gas that is directed from the inside against the inner surface of the at least one sheet guide device, and/or characterized in that at least one pre-alignment device (767) is arranged, in a stationary manner, in a region of the at least one blower drum (712), which is an integral part of a respective alignment device (771) and comprises at least one solenoid and/or permanent magnet.
