Embodiment Construction

[0017] Refer to attached Figure 1-6 The present invention will be described in detail.

[0018] figure 2 An ink fountain device for a rotary printing press according to an embodiment of the present invention is shown. Refer to attached figure 2 , the ink fountain roller 1 rotatable in the direction shown by arrow A extends axially between a pair of frames (not shown) which are arranged to face each other through a predetermined distance, and the doctor blade base 2 is arranged on the ink fountain roller 1 so that its ends are supported by the pair of racks. A large number of fountain keys 3 divided in the axial direction of the fountain roller 1 are placed on an inclined surface at the upper end of the doctor blade base 2 . When a motor (not shown) is driven, the aperture ratio of the distal end or tip of the ink fountain key 3 is adjusted in various directions to approach and move away from the outer surface of the ink fountain roller 1 .

Abstract

An ink fountain apparatus for a rotary printing press includes an ink fountain (6), an intermediate ink dam, and press unit for simultaneously pressing the intermediate ink dam toward the outer surface of the fountain roller and toward the upper surface of the bottom plate. A width (t) of the first surface close to the boundary portion in the axial direction of the fountain roller is set to be smaller than a width (T) of the first surface arranged upstream of the fountain roller in a rotational direction from the boundary portion in the axial direction of the fountain roller. <IMAGE>

Description

technical field [0001] The present invention relates to an inkfountain arrangement for a rotary printing press, which stores ink to be supplied to the surface of a printing plate. More particularly, the present invention relates to an ink fountain assembly for a rotary printing press having an intermediate ink dam disposed between a pair of opposing ink dams. Background technique [0002] When printing with a rotary printing machine, depending on the specification of a printed product, sometimes a printing plate has a pattern at only a part of its entire width. In this case, if ink is kept in the entire ink fountain and printing is performed, ink may be wasted. For this reason, intermediate ink banks are formed on both sides of the portion corresponding to the pattern, and ink is stored only inside the intermediate ink banks. When performing multi-color printing, that is, inks of different colors are supplied to appropriate parts of the entire length of the printing plate ...
