Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
119 words
THE METHOD OF MOISTENING A ROTATING PRINTING PLATE CYLINDER INCLUDING THE STEPS OF DIRECTING A FLOW OF LOW PRESSURE AIR AGAINST A MOVING SCREEN HAVING A MOISTENING LIQUID ENTRAPPED THEREIN WITH THE FLOW BEING IN A DIRECTION INCLINED TO THE SURFACE OF SAID SCREEN AND DIRECTED TOWARD THE PLATE CYLINDER IN THE GENERAL DIRECTION OF ROTATION OF THE PLATE CYLINDER, THE FLOW BEING INCLINED IN THE DIRECTION OF SAID MOVEMENT OF SAID SCREEN, THE INCLINATION OF THE AIR FLOW IN RELATION TO SAID SCREEN SURFACE BEING SUCH AS TO AVOID SUBSTANTIAL SURFACE REFLECTIONS OF THE AIR FLOW BY SAID SCREEN AND AT THE SAME TIME LARGE ENOUGH TO AVOID FORCING THE MOISTENING LIQUID DOWN THE SURFACE OF SAID SCREEN.

Claim 3
Dependent Claim
137 words
A MOISTENING ASSEMBLY FOR USE WITH PRINTING PLATE CYLINDERS INCLUDING A CYLINDRICAL SCREEN AND MEANS MOUNTING SAID SCREEN FOR ROTATION, A MOISTENING SOLUTION RESERVOIR POSITIONED BENEATH SAID SCREEN SO THAT THE LOWER PORTION OF SAID SCREEN MOVES WITHIN A MOISTENING LIQUID CARRIED BY SAID RESERVOIR DURING ROTATION BY SAID SCREEN, A MANIFOLD POSITIONED WITHIN SAID SCREEN AND HAVING AN AIR OUTLET ORIFICE POSITIONED ADJACENT TO THE SURFACE OF SIAD SCREEN FOR DELIVERING AN AIR FLOW TO THE SCREEN, SAID ORIFICE BEING ELONGATED AND BEING INCLINED TO A RADIUS OF SAID SCREEN WHICH INTERSECTS THE SCREEN AT THE MID POINT OF CONTACT WITH SAID AIR FLOW, AND MEANS DELIVERING LOW PRESSURE AIR TO SAID MANIFOLD, THE AIR BEING DELIVERED IN A VOLUME SUCH THAT THE MANIFOLD IS KEPT UNDER SUBSTANTIALLY THE SAME PRESSURE THROUGHOUT THE ENTIRE LENGTH THEREOF.
