Abstract
An integrated ink rail assembly includes at least one page pack mounted directly to a manifold, an ink rail mounted to the manifold, and an orifice rail mounted to the ink rail. An ink source is connected to the page pack. The page pack, manifold, ink rail, and orifice rail define a plurality of ink passages to deliver ink from the ink source to a drum. The ink passage may be directed towards the middle of the assembly such that a web smaller than the page pack can be printed.
Claims34
An integrated ink rail assembly with a left end, a right end, and a middle, comprising:
- a page pack including an ink inlet adapted to receive ink from an ink source and a pump adapted to pump the ink through an ink path, the page pack having an ink outlet face;
- a manifold having an ink inlet face, the page pack being directly mounted to the manifold;
- an ink rail mounted to the manifold;
- and
- an orifice rail mounted to the ink rail and adapted to deliver ink to a drum;
- the page pack, manifold, ink rail, and orifice rail each including an ink passage, the ink passages defining the ink path between the ink source and the drum;
- wherein the ink outlet face of the page pack is in confronting relationship with the ink inlet face of the manifold.
A print press, comprising:
- a frame;
- a drum mounted to the frame and adapted to receive and transfer ink;
- a manifold with an ink inlet face and an ink outlet face rotatably mounted to the frame;
- a page pack with an ink outlet mounted to the ink inlet face of the manifold;
- an ink rail mounted to the ink outlet face of the manifold;
- a first orifice rail and a second orifice rail, each of the first and second orifice rails selectively mountable to the ink rail and adapted to deliver ink to the drum;
- the page pack, manifold, ink rail, and the selected orifice rail defining an ink path between the ink source and the drum;
- and
- an actuator configured to shift the manifold from a work position in which the orifice rail delivers ink to the drum to a service position in which the orifice rail is accessible;
- wherein the first orifice rail includes an outwardly extending ink path wherein at least some of the ink traveling through the first orifice rail is directed outward away from the middle of the first orifice rail;
- and
- wherein the second orifice rail includes an inwardly extending ink path wherein at least some of the ink traveling through the second orifice rail is directed inward toward the middle of the second orifice rail.
An adjustable ink rail assembly with a right end, a left end, and a middle, comprising:
- an ink rail with an ink inlet face and an ink outlet face, a plurality of ink inlets and ink outlets, and an ink path fluidly connecting each ink inlet to an ink outlet;
- and
- an orifice rail with an ink inlet face and an ink outlet face, a plurality of ink inlets and ink outlets, at least one orifice rail ink inlet being in fluid communication with a corresponding ink rail ink outlet, an orifice rail ink path fluidly connecting each ink inlet to a corresponding ink outlet;
- the orifice rail being removably attached to the ink rail;
- wherein ink traveling through the orifice rail ink passage is displaced axially with respect to the ink rail ink outlet;
- and
- wherein the orifice rail ink path includes a slot in the orifice rail ink inlet face.
An adjustable ink rail assembly with a right end, a left end, an a middle comprising:
- an ink rail with an ink inlet face and an ink outlet face, a plurality of ink inlets and ink outlets, and an ink path fluidly connecting each ink inlet to an ink outlet;
- an orifice rail removably attached to the ink rail, the orifice rail including an ink inlet face and an ink outlet face, a plurality of ink inlets and ink outlets, at least one orifice rail ink inlet being in fluid communication with a corresponding ink rail ink outlet, an orifice rail ink path fluidly connecting each ink inlet to a corresponding ink outlet;
- wherein each orifice rail ink path includes a directional component either toward or away from the middle of the orifice rail, wherein at least some of the ink traveling through each orifice rail ink path is directed either toward or away from the middle of the orifice rail.
