Abstract
An ink pan for a rotogravure printing press has a reservoir and a dam. The dam is located within the reservoir and divides the reservoir into an intake section and an outtake section. A gate is within the dam. The gate has an open position and a closed position. When the gate is closed the dam maintains an ink in the intake section until the ink exceeds a depth greater than the height of the dam, and then the ink flows over the dam into the outtake section. When the gate is in an open position the gate allows ink in the intake section to be emptied into the outtake section.
Claims12
An ink pan for a rotogravure printing press comprising:
- a reservoir with an open top and a bottom for holding an ink;
- a dam within said reservoir dividing said reservoir into an intake section and an outtake section;
- a vortex promoter located within said reservoir creating turbulence in the ink between a gravure cylinder and said reservoir;
- said vortex promoter being a protrusion along said bottom of said reservoir;
- and
- a gate within said dam having an open position and a closed position;
- when said gate being in said closed position, said dam maintains ink in said intake section up to a height of said dam where said ink flows over said dam into said outtake section;
- and
- when said gate being in said open position, ink from said intake section empties to said outtake section.
