Vertical ink metering apparatus

Image Number 6 for United States Patent #4401032.

Dry offset printing apparatus for high speed printing on cylindrical objects fed either horizontally or vertically to the printer, which comprises a three-roller system including a single roll ink-metering system, plate cylinder and blanket or p rint roll. The ink roll is provided with a relatively soft, smooth elastomeric surface as is also the offset print roll blanket. A doctor blade is configured and oriented with respect to the ink roll to meter a uniformly even, thin film of ink onto the roll. Means are provided for evenly distributing the ink film on the ink roll in both horizontal and vertical embodiments of the printer. Means are also provided to prevent excessive ink buildup on print roll when skips occur at the printing station. Rotary transfer means are provided for positively feeding the cylindrical objects to the printer at high speeds in either horizontal or vertical orientation.
