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 interacting 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, characterised in that, on at least one of the longitudinal sides of the printing unit (01) a barrier (42) is provided, wherein said barrier (42) on one of the frame parts (13; 14) is mounted, wherein with this barrier (42), an access to the intermediate space (17) it can be blocked, wherein said barrier (42) in its the access to the intermediate space (17) relative to one another operating state between the closing position variable frame parts (13; 14) as a function of a movement of these frame parts (13; 14) is of variable breadth, wherein in the intermediate space (17) between the mutually positionally variable frame parts (13; 14) a..
