Mono-block inkpot for adductor rolls of offset printers.

摘要

This inkpot for adductor rolls of offset printers is equipped with a structure of elevated flexion-torsion non-deformability, preferably mono-block, made to be integrated with a levelling screw device, regulator of the thickness of the ink film transferred by the adductor roll, thereby making the maneuvers inherent in the regulation more trustworthy.The inkpot is equipped with a levelling screw regulator device, entrusting the maneuvering of these to motorized means, acting by means of the intervention of angular velocity reducers , thereby amplifying the shift of the maneuver, in order to more clearly define its quality.The inkpot is equipped with levelling screws, which execute their axial regulatory advancement, by a tightening between screw and nut bolt, under differential application.The inkpot is equipped with levelling screws activated by the application of regulatory screws, under preloading by elastic means, which are eliminators of the axial play of coupling.The inkpot is equipped with lateral shoulder flanges with ends of anti-friction material, and shaped so as to unite to the circularity of the adductor roll, thereby permitting it to lean against them, without creating the possibility of contact between their levelling screws and the cylindrical surface of the adductor roll, during the installation phases onto the offset printer.
