Abstract: A printing group of a printing machine is comprised of a pair of cylinders each having a circumference that corresponds essentially to a length of a section of a side to be printed. The effective generated surface of at least one of the cylinders comprises, at the most, one break in the circumferential direction. The surface forms, in the longitudinal direction, a plurality of adjacently arranged breaks which, when viewed in the circumferential direction, are arranged in a staggered manner with respect to each other.

Abstract: The invention relates to a printing group pertaining to a printing machine, comprising at least two cylinders, i.e. a form cylinder and a transfer cylinder. Said transfer cylinder can be optionally brought into a print-on position or a print-off position along a linear adjustment path. Both cylinders can be driven in a mechanically rotating manner, independently from another printing group, by means of at least one drive motor arranged on the frame in a fixed mode.

Abstract: The invention relates to the cylinder of a rotary printing machine in which cylinder two channels are arranged off-set from each other by an angle &phgr;, said angle &phgr; being determined depending on the moment of flexion frib inherent to the cylinder.

Abstract: The invention relates to a cylinder of a rotational printing press. Two channels are offset from each other by an angle &phgr; which is fixed according to the natural bending frequency frib of the cylinder.
