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.

No-feed-roll corrugated board or paperboard sheet feeder retrofit apparatus and method

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatusis configured to upgrade an installed corrugated board processing machine (e.g.,) and includes a feed table surfacefor boards (e.g.,) having drive wheels (W,W,W) in an initial variable velocity zonewhich drives the board in a first motion profile through a first vacuum zone, and a second velocity zonewhich then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feederalso includes a controllerconfigured to receive predetermined velocity signals from the host machineand generate (i) a first initial variable velocity control signal for initial variable velocity zoneand (ii) a second velocity control signal for second velocity zonein response.
