ABSTRACT:
In an ink fountain device for use in a printing press of the type wherein printing ink is supplied through a gap between an inking roller and an adjustable inclined blade, the blade includes a plurality of juxtaposed sections divided along the inking roller, and a magnetic plate having the same width as the combined width of the blade sections. The magnetic plate is attracted to the blade sections by permanent magnets provided for the respective blade sections. Permanent magnets can also be provided for the respective blade sections or a blade support for firmly attracting the blade sections to the blade support. The construction not only permits fine adjustment of the quantity of ink in each section in accordance with the contrast of printed patterns but also prevents the printing ink from entering between the blade sections and the magnetic plate, and between the blade sections and the blade support.
