Abstract

To close the gaps (6) which result between the end or edge sections (7) of the gravure printing plates (2) when the latter are clamped on form cylinders (1) of rotary gravure presses, the gap (6) is covered with a cover element (8) in which at least that surface region which lies on the end or edge sections (7) of the gravure printing plate (2) and covers the gap (6) is deformable under pressure and can therefore be matched up with the surface contour in the gap region, the cover element is pressed onto the surface of the gravure printing plate, the resulting gap cavity is filled with a curable filling compound and, when curing of the filling compound is complete, the cover element is removed. It is particularly advantageous to use cover elements which are in the form of hollow bodies and which are filled with a pressure-generating and pressure-transmitting medium, and the pressure exerted on the deformable surface of the cover element which lies on the gravure printing plate, and hence also the surface contour of the closed gap, can be controlled via the internal pressure in the cavity of the cover element.
