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. A web width indicator associated with the spring plunger may be used to guide the operator to an appropriate skew setting for a particular web width. The skew adjustment rod may also include a fine tuning mechanism, used to make minor adjustments to the skew settings for the dampeners, for example, when a particular setting is between one of the settings established by the pin-hole arrangement.
