Abstract In an ink fountain device for a printing press of the type wherein a plurality of divided blade sections are adjustable toward and away from an ink fountain roller and a covering plate covering the divided blade sections is attracted to the divided blade sections by permanent magnets embedded in the divided blade sections, an inner end of the covering plate is spaced a predetermined distance away from the ink fountain roller and slanted downwardly and an angle between the slanted surface and an upper surface of the covering plate is made to be smaller than that between the upper surface and a tangent passing through a point on a periphery of the ink fountain roller confronting an inner end of the divided blade section. According to this construction bending up of the covering plate can be prevented so that leakage of the ink into a gap between the divided blade sections and the covering plate can be prevented.
An ink fountain device for a printing press comprising: an ink fountain roller; an ink fountain frame inclined toward said ink fountain roller; a plurality of divided blade sections juxtaposed on said ink fountain frame, with their adjacent sides in close contact; a covering plate covering entire surfaces of said divided blade sections, said covering plate being made of magnetic material and being removably mounted on said divided blade sections; a plurality of permanent magnets embedded in said divided blade sections for attracting said covering plate to said divided blade sections; an inner end of said covering plate being spaced a predetermined distance from a periphery of said ink fountain roller and slanted downwardly; and an angle between the slanted surface and upper surfaces of said covering plate being smaller than an angle between a tangent passing through a point on the periphery of said ink fountain roller confronting inner ends of said divided blade sections and the upper surfaces thereof.
