REGULATING DEVICE FOR REGULATING AT LEAST ONE DEFINED PERIPHERAL REFERENCE POSITION OF A CYLINDRICAL PRINTING ELEMENT COMPRISING AT LEAST ONE MODEL UNIT, A CONTACT SENSOR DEVICE FOR ONE SUCH REGULATING DEVICE AND A PRINTING DEVICE COMPRISING SUCH REGULATING DEVICES
REGULATING DEVICE FOR REGULATING AT LEAST ONE DEFINED PERIPHERAL REFERENCE POSITION OF A CYLINDRICAL PRINTING ELEMENT COMPRISING AT LEAST ONE MODEL UNIT, A CONTACT SENSOR DEVICE FOR ONE SUCH REGULATING DEVICE AND A PRINTING DEVICE COMPRISING SUCH REGULATING DEVICES
The invention relates to a regulating device (1) for regulating at least one defined peripheral reference position of a cylindrical printing element (8) comprising at least one model unit. Said regulating device comprises a measuring surface (44) which rotates together with the printing element (8) and has an identifying mark (5) which can be electrically detected, an electroconductive contact sensor (21) which is associated with said mark, and an electrical control device (3). Said contact sensor (21) can be moved into an electroconductive bearing position on the mark (5) of the measuring surface (44). A sensor switching circuit (31) is electrically closed in the bearing position. Said identifying mark (5) has an area (51,52) which leads to a change in the resistance of the sensor switching circuit (31) and, as a result, the defined circumferential rotation of the printing element (8). The contact sensor (21) is especially formed by means of a pneumatic sensor displacement device (22). Each printing station in a printing device is fitted with a regulating device (1).
