Cylindrical container silk screen printer with coordinated screen height and stroke adjustment indexing mechanism

A device for a silk screen printing the outer peripheral surface of a cylindrical container comprising, in combination, a first carriage means for supporting a printing screen prepared with printing indicia;

• a second carriage means beneath said printing screen for supporting the container to be printed for rotational movement about its longitudinal axis, means for measuring the diameter of a container, means connecting said diameter measuring means with a first drive means to sequentially move said second carriage means, with said container, into and out of a position whereat the cylindrical surface of said container is in abutting contact with the bottom surface of said screen, a second drive means to reciprocatively drive said first carriage means to effect a printing stroke in a first directiion and a return stroke in the opposite direction, means to force ink deposited on the top surface of said printing screen through said silk screen, a third drive means to move said ink forcing means into engagement with the top surface of said screen on said printing stroke to effect printing of said indicia on the cylindrical container surface and to raise said ink forcing means from said top surface on said return stroke, and means for adjusting said printing and return strokes of said first carriage means so as to be correlated with the diameter of the container being printed and the movements of said second carriage means.
