Abstract
A plate clamping assembly for securing a printing plate to a plate cylinder of a rotary printing machine utilizes spaced clamping bars which are each pivotably positioned in a groove in the plate cylinder. An axially slidable and rotatable shaft cooperates with one of the clamping bars while an axially fixed and rotatable adjusting shaft cooperates with the other clamping bar. Both adjusting shafts having a plurality of truncated cones which engage tappet arms on the clamping bars.
Claims5
A plate clamping assembly useable to clamp and to slidably and skewably position a printing plate on a plate cylinder of a rotary printing machine, said plate clamping assembly comprising:
- first and second spaced clamping bars, each of said clamping bars being axially slidable and pivotable in a groove in the plate cylinder, each of said clamping bars being adapted to receive an end of the printing plate;
- first and second rotatable adjusting shafts associated with said first and second clamping bars respectively and being positioned in said groove and each having a plurality of axially spaced truncated cones said truncated cones being positioned eccentrically with respect to axes of rotation of said adjusting shafts, one of said first and second rotatable adjusting shafts being axially slidable;
- and
- means for communicating said axial sliding movement of said one of said adjusting shafts to said first and second clamping bars.
