ABSTRACT:
An ink metering blade to control the thickness of an ink film along a fountain roll in a printing press. The blade has a plurality of metering segments which are movable relative to each other by flexing the blade. The flexible construction of the blade is promoted by having slots separating metering segments. The slots are filled by seal members which block a flow of ink through the slots. The seal members are ineffective to transmit force between metering segments of the blade to enable the positions of the metering segments to be accurately adjusted relative to each other. The seal members have a narrow seal section which is disposed in the space between the metering segments and a relatively wide mounting section which is disposed beneath a metering segment. The mounting section may be connected with a metering segment by adhesive. However, a second or backing blade or member may be used to hold the seal members in place.
