ABSTRACT:
A mechanism for zonal adjustment of the blade of an ink fountain with respect to the fountain roller which is made up of adjustable subassemblies, each of which includes an adjusting pin secured to a slide. Adjacent each slide is a support member carrying a cylindrical adjusting member having an eccentric crank for engaging and positioning the slide. The adjusting member has a radially extending adjusting arm and a positive detent, the arm having a calibrated scale including a reference mark which is phased with the detent. Each pin is threaded into its slide so that when the adjusting arms are in detented reference position, the blade may be preliminarily adjusted, zone by zone, into accurate reference spacing with respect to the blade by turning the pins in one direction or the other in each of the subassemblies. The blade is finally adjusted in each zone by movement of the corresponding arm with respect to the calibrated scale to establish a running condition.
