Abstract: A device for providing cleaning or other solution in a printing press including a spraying device, the spraying device having a liquid exit disposed along a width of the spraying device for delivering a liquid to a press component and a spray shield selectively covering at least one part of the liquid exit so as to block delivery of the liquid through the at least one part to the press component. Also disclosed is a method for providing cleaning or other fluid to a printing press component comprising the steps of spraying a fluid over a fixed width of a press component, and blocking part of the fluid over a part of the fixed width so that the part of the fluid does not reach the press component.

Abstract: A method and apparatus for adjusting skew settings in a dampener in a printing press. One or more skew adjustment linkages connect skew adjustment rods for the upper and lower dampeners of each printing unit. The linkage ensures that a single movement by the operator will allow adjustment of the skewing of both the upper and lower dampeners at the same time. The linkage or linkages are preferably connected at one end to skew adjustment brackets, which in turn are connected to a skew adjustment rod for one of the upper or lower dampeners. The skew adjustment rod adjusts the amount of skew of associated pan rolls. Movement of the linkage may be controlled by movement of a spring plunger, which is connected to the linkage or linkages. The spring plunger may be spring biased, and may be adjusted and locked into different skew setting positions using a pinhole arrangement.

Abstract: The present invention is related to an apparatus for delivering flat products, such as signatures, in a folding apparatus of a rotary printing press. At least one fan wheel assembly has a plurality of fan blades separated from each other by fan wheel pockets. The fan wheel pockets are defined by surfaces of the fan blades. A first surface of each fan wheel pocket is configured to cause the signature to take on an energy dissipating state.
