Abstract
A high speed unit printer comprising an intermittently rotating ink disc having a substantially horizontal surface on which a supply of ink is deposited. A collecting blade continuously directs the ink into a narrow stream near the periphery of the disc. An adjustable metering blade continuously spreads the ink stream from the collecting blade into a band of uniform thickness. An inking pad and a transfer pad are mounted on a common slide assembly which reciprocates to transfer ink from the disc to an adjacent plate or type, and an image from the plate or type to the article to be printed. The slide assembly is mounted on a pivotally mounted slide arm assembly which is raised during reciprocating movement of the slide assembly by a rotating cam.
