For automating the placement or removal of printing plates on plate cylinders (16, 17) of rotary printing machines, particularly web printing machines, an application head (11) is secured to a multiple linked roboter arm (2), slidable vertically along a guide post (1). The roboter arm can be pivoted about the axis of the guide post, moved vertically thereabout, and includes a plurality of joints (3, 4, 5, 6) which connect roboter arm link elements (7, 8, 9, 10). The positioning head (11) is located at the roboter arm element (10) most remote from the guide post. The guide post is positioned between the axes of rotation of printing cylinders of adjacent printing stations, axially removed from the path of the web between the printing stations, so that interference with the web is effectively avoided.
