Ink Feed System
The drawing depicts an on-demand document endorsing mechanism,
including a continuously feeding inking device.
The ink system consists of an ink roll 1 and ink reservoir 3 with a wick 5.
The ink reservoir, including wick, is contained in a frame 7 which is pivoted at 9
to facilitate reloading and to bring the wick in contact with the ink roll.
The ink roll 1 is a polished chrome-plated roll that is run continuously,
remaining in constant contact with the ink reservoir wick.
The spring 11 shown applies the necessary normal force required to facilitate
As the ink roll turns, ink is applied to its periphery from the wick and
immediately forms little beads. The combination of the polished ink roll surface
and the wick-wiping action permits a certain amount of ink transfer, keeping the
device always ready for ink transfer to the print sector 13 which wipes by roll 1 on
This unique combination also provides "self-doctoring", thus not allowing the
ink film on ink roll 1 to build up in excess when not being removed by the wiping
action of the print sector.
