Abstract: A method is provided for supplying a corrugated board article or a paperboard sheet article from a feeder apparatus for receipt by an article processing host machine. The method includes feeding the article to a feeder apparatus including a sheet supporting feed table surface having a feed end and a delivery end, feed elements, and a control surface selectively movable between a covering state and an exposing state. In the exposing state the feed elements are exposed to contact and drive the article along the sheet supporting feed table. The control surface is selectively movable to an angled state to selectively angle the control surface to consecutively conceal the respective feed elements as the article moves over the feed elements.

Abstract: A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.

Abstract: An electrically powered and electronically controlled diaphragm ink pump apparatus (e.g., 100, 200 or 300) and method for synchronous pressurization of ink in a corrugated board sheet feeding system comprises a diaphragm pump assembly including a reciprocating electrically driven crank mechanism connected to and driving first and second diaphragms or diaphragm surfaces, each diaphragm or diaphragm surface housed within a pump housing (e.g., 140, 240 or 340) having an ink inlet and an ink outlet in fluid communication with a manifold configured for pumping liquid ink to printing sections of a corrugated paperboard finishing machine 10 and provide a smooth reciprocating action and more uniform ink flow with reduced pressure pulsations.
