Automatic inking mechanism for paperboard printing machines

摘要

The present invention relates to an automatic inking mechanism used on a common paperboard printing machine, it mainly comprises a framework reciprocatively movable on a pair of rack rails. Induction means disposed on the framework actuates a cylinder attached to the framework to move up and down an ink reservoir from which adequate amount of ink can be automatically applied to rollers of the printing machine for printing patterns at preset positions on a paperboard with even ink consistency and clear printed letters or patterns.
