US Patent 6813998: Pad printing machine

US 6813998  ยท  granted 2004-11-09

Abstract

A printing plate is supported on a table slideably mounted on a frame for forward and back horizontal movement. A table lever has a handle moving in a vertical plane to slide the table for inking an image on the plate with an inverted ink cup or for moving the inked image under a printing pad. A printing pad shaft is supported by a mast for vertical sliding movement of the printing pad down onto the inked image or onto a work piece supported by a work holder bracket adjustably attached to the table. A printing pad lever has a handle moving in a second vertical plane to move the printing pad shaft. A printing cycle includes a minimum number of sequential movements of the two handles in parallel vertical planes located side by side.
