The present invention relates to an ink supplying apparatus equipped with an ink tray capable of improving the productivity based upon the labor-saving of an cleaning operation and the shortening of a preparatory time at ink replacement or the like in a printing press, with the ink tray being desirably attachable/detachable to enhance the operational efficiency. In front of an ink fountain, there is provided a fixing device which, for fixing an ink tray in the interior of the ink fountain, presses a bracket of the ink tray against a stopping section situated in the ink fountain. The fixing device is made up of a supporting member placed under a mounting plane of the bracket, a rotating member made to be rotatable in a plane substantially perpendicular to a cross direction of the apparatus in a state where its one end portion is supported by the supporting member, a pressing member provided on the rotating member for pressing the bracket in a state where the rotating member rotates upwardly so that the ink tray is fixed in the ink fountain, and an arresting member for arresting the rotation of the rotating member when the pressing member presses the bracket.

The present invention provides an ink supply apparatus for a printing press in which the ink supply amount from an ink fountain to an ink fountain roller is controlled by regulating a gap between ink blades and the ink fountain roller, wherein an integral type ink tray comprising a bottom portion covering portions of the upper faces of the ink blades excluding the distal end portions thereof and side portions covering the inside surfaces of side plates is provided, a first seal member is interposed between the inside surface of the side plate and the side portion, and a second seal member in slidable contact with the ink blades is interposed between the ink blades and the bottom portion of the ink tray.

The present invention relates to an ink supply device and an ink key thereof and makes it possible to stabilize the action of the ink key and to save labor in cleaning of the ink key by preventing the ink from getting into a gap between the neighboring ink keys. A cover member imperviously covering the surfaces of a plurality of ink keys is mounted in an ink box to reduce an area where the ink keys are in direct contact with the ink and a an inset is made into one or both of the walls of each of the plurality of neighboring ink keys covered by the cover member, the inset extending from the top surface of the ink key to the bottom surface thereof, so that even if the ink leaks and gets into a gap between the ink keys because of capillary phenomenon, the wall inset provides an enlarged space between the keys which prevents the ink from spreading the gap between the ink keys.

The present invention relates to an ink supply device and an ink key thereof and makes it possible to stabilize the action of the ink key and to save labor in cleaning of the ink key by preventing the ink from getting into a gap between the neighboring ink keys. A cover member hermetically covering the surfaces of a plurality of ink keys is mounted in an ink box to reduce an area where the ink keys are in direct contact with the ink and a groove is made on one or both of the sides of each of the plurality of neighboring ink keys covered by the cover member from the top surface of the ink key to the bottom surface thereof, and even if the ink leaks and gets into a gap between the ink keys because of capillary phenomenon, the groove prevents the ink from spreading the gap between the ink keys.

There is provided a removable ink cassette for a flexographic printing press containing an ink pan and a meter roll. The ink pan and the meter roll are removed from the printing press together by removing the ink cassette from the printing press. The ink pan may be removed from the printing press without first removing the anilox roll and the meter roll.
