Abstract
In an ink supply apparatus, inks of a paste-like consistency are supplied from a cylinder to a chamber doctor blade disposed adjacent an inking roller. Two conduits are disposed at opposite ends of the chamber doctor blade and each conduit communicates with one of the two opposite ends of the cylinder. Ink is supplied to the cylinder through an aperture. Within the cylinder there is disposed a reciprocating piston which, at low speed, forces ink via the conduits to the chamber doctor blade.

An apparatus for supplying ink to an inking roller, comprising:
- a cylinder having a reciprocating piston therein, the cylinder having first and second ends and an aperture between the ends for receiving ink;
- a doctor blade having a chamber for containing ink;
- a first conduit connecting the first end of the cylinder to the chamber of the doctor blade;
- a second conduit connecting the second end of the cylinder to the chamber of the doctor blade, said first and second conduits being connected with the chamber at spaced apart locations;
- means for reciprocating the piston between the first and second ends of the cylinder;
- whereby ink flows from the cylinder to the chamber when the reciprocating means moves the piston toward an end of the cylinder.
