Sheet-fed rotary printing machine comprising an electrode unit

A sheet-fed rotary printing machine, the sheet-fed rotary printing machine comprising at least one coating unit (05;

• 06;
• 07), which comprises at least one impression cylinder (34;
• 61) and at least one further cylinder (33;
• 63) forming a contact zone (55) with the impression cylinder (34;
• 61) and designed as a transfer cylinder (33) or finish coating forme cylinder (63);
• and the coating unit (05;
• 06;
• 07) comprising at least one charging device (86) for electrostatically fixing sheets (B) on the impression cylinder (34;
• 61), the charging device comprising at least one electrode unit (88) that is directed and/or can be directed toward an outer cylindrical surface (87) of the impression cylinder (34;
• 61);
• and a charging core zone (89) being a region (89) of an outer cylinder surface (92), enveloping a cylinder barrel (91) of the impression cylinder (34;
• 61), which is located closest to the at least one electrode unit (88);
• and the charging core zone (89) being arranged downstream from the contact zone (55) and upstream from a transfer point (101) leading away from the impression cylinder (34;
• 61), viewed in the direction of rotation (R) of the impression cylinder (34;
• 61), characterized in that at least one electrode (93) of the at least one electrode unit (88) has a minimum first distance (94) with respect to the impression cylinder (34;
• 61), which is at least 4 mm and which is no more than 13 mm, and that the at least one electrode (93) of the at least one electrode unit (88) has a minimum second distance (96) with respect to the further cylinder (33;
• 63), which is at least 4 mm and which is no more than 35 mm.
