中に生ずる衝撃力を吸収するのに役立つに過ぎない。PRIOR ART The actuation of the adjusting screw for the insert via a bevel gear from the adjusting shaft in order to move the insert in the radial direction for tensioning a flexible printing plate is disclosed in DE-PS 640 262. It is known from the book. In this case, when the adjusting spindle is turned, all adjusting screws are actuated uniformly, but precise adjustment of the insert in the radial direction is not possible or possible. This is because the insertion piece must always be moved until it presses against the edge of the entire printing plate. Furthermore, the support at the edges of the fuselage groove only serves to absorb impact forces occurring during driving.

度の異なる筋が生ずるようになる。Advantages of the Invention The present invention has the advantage of not only being applicable only in the case of rotary printing presses, but also of reducing the impact of the pressing force between the two cylinders as they pass through the cylinder grooves, in order to ensure a satisfactory P-lid function. In order to avoid such fluctuations, it can also be applied in other rotary printing presses, in particular for offset or rotary printing presses. These dramatic fluctuations in pressure force result in streaks of varying ink density on the printed signature.
