Ink fountain devices for use in printing press

摘要

In a ink fountain device for use in a printing press of the type wherein an ink fountain roller is dipped in an ink pot and a quantity of ink supplied to the printing press is controlled by varying a gap between the ink fountain roller and a blade, the blade is divided into a plurality of sections along the length of the ink fountain roller. Each divided blade is normally urged by a spring to move away from the ink fountain roller and further urged toward the same by another spring and an adjusting screw through a roller urged against a rear end of the divided blade. In this manner, respective blades can be independently adjusted so as to adjust the thickness of ink film along the length of the fountain roller, to be commensurate with a tone or contrast of a printed matter.
