Printing unit of a printing press with at least two relative to each other parts of the frame position variable

摘要

Printing unit (01) of a printing press with at least two relatively position variable frame parts (13; 14), wherein first and second cooperating parts of the frame (13; 14) in a first operating position on a common joint surface (16) inclined towards one another and in a second operating position are bent away from one another, wherein between the disengaged from each other parts of the frame (13; 14) in the printing unit (01) one of these frame parts (13; 14) partially limited space (17) is formed, of the respective cooperating first and second parts of the frame (13; 14) at least a first frame part (14) along a linear path (s) is movably arranged, characterized in that at least one the intermediate space (17) sensor, which monitors (31) with a along the joint surface (16) effective directional characteristic (32) is provided, wherein the directional characteristic (32) at least in one spatial direction with respect to at least one of the other two orthogonal directions in space is highly concentrated, so that the directional characteristic (32) on the movable frame part (14) flat along the joint surface (16) runs.
