Abstract
An ink feeding system for feeding ink to an ink fountain of a printing, duplicating or like machine includes a can holder for holding a can of printing ink. A support arm suspends the can holder and can above the ink fountain. A piston-and-cylinder device feeds ink from the suspended can through a hole in the closed bottom end of the can and into the ink fountain. A disposable gasket is placed on top of the ink in the can for engagement by a piston head of the piston-and-cylinder device.
