  • Ink-dispensing system and method for silk-screen printing having squeegee stroke movement counter
    Patent number: 4485736
    Abstract: Disclosed is a system for dispensing ink to a silk screen for printing thereby. A squeegee is reciprocated relative to the silk screen and each cycle of movement provides an air pulse to a counter. The counted pulses are compared with a preset number of pulses based on the actual amount of ink which is used during the printing operations. When the counted pulses are counted up to the preset number, a control signal is fed to a valve to operate a piston and cylinder assembly which is coupled to a piston to force a measured quantity of ink from a cylinder. The cylinder is fed with a supply of ink from an ink pot. A check valve in the bottom of the cylinder opens only when the ink in the cylinder is pressurized by the piston. The measured quantity of ink dispensed from the cylinder is delivered by a conduit to the silk screen.

  • Silk-screen printing method and apparatus
    Patent number: 4463671
    Abstract: Printing on a cylindrical or conical surface of a container is carried out by a method and apparatus wherein the container is supported against rotation about a support axis. A squeegee is positioned at one side of a decorating screen to establish line contact between the opposite side of the screen and the surface of a container. The decorating screen is rolled along a tangential path about the surface of the container and concurrently the squeegee is moved along an orbital path about the support axis to force printing medium through the screen onto the surface of the container at the line of contact therewith.
