Offset printing machine

A web-fed offset printing machine comprising printing units having at least one form cylinder and one transfer cylinder (1.1 to 1.5;

• 2.1 to 2.5);
• and at least one folder unit (25);
• and wherein, for each printing unit, at least one of said form and transfer cylinders (1.1 to 1.5;
• 2.1 to 2.5) has a drive connection to a separate electric motor, said at least one cylinder (1.1 to 1.5;
• 2.1 to 2.5) having one selected from the group consisting of no mechanical drive connection to a further one of said cylinders (1.1 to 1.5;
• 2.1 to 2.5) when said further cylinder is driven directly or indirectly by a further separate electric motor and a mechanical drive connection to one of said further cylinders(1.1 to 1.5;
• 2.1 to 2.5) when said further cylinder is not driven by a separate electric motor;
• said printing machine further comprising a motor control system (41, 52, 56, 66, 73) for said at least one electric motor for adjusting a printing group (3, 4, 12, 13, 14, 24, 25, 46, 47, 58 to 61, 67, 68) and for presetting said printing units for adaptation to a different web path, said motor control system having an input side;
• and
• a computing and memory unit (45, 52, 57, 65, 74) for storing a plurality of cylinder positions connected to said input side of said motor control system;
• and wherein said motor control system (56, 66) for said electric motor (7) of a printing group (58 to 61) is connected on said input side to said computing and memory unit (57, 65) for setting a cutting register by said electric motor, said computing and memory unit having stored therein cylinder positions for said cutting register for possible web paths for setting said cylinders (2.1 to 2.5) of all printing groups (58 to 61) that print a web (155, 62) into predefined positions for the respective web path.
