<p>Described herein is a high capacity, high reliability cassette tray sheet feeding assembly (70) for supporting a high capacity stack of sheets, and for feeding such sheets with a high degree of reliability, one at a time, in a sheet using machine. The assembly (70) includes a cassette frame (74) for removing and reinstalling into a sheet supply station of the sheet using machine. The cassette frame (74) includes a fixed position stationary base plate (96) for supporting a high capacity stack (94) of sheets. The high capacity, high reliability cassette tray sheet feeding assembly further includes a variable position sheet receiving path (104), and a pivotable feed wheel assembly (100) for reliably feeding topmost sheets seriatim from the stack (94) into the variable position sheet path (104). The pivotable feed wheel assembly (100) provides a constant sheet feeding angle (F3°), and a constant sheet feeding normal force (P3), thereby enabling continuous high reliability feeding of sheets.</p> |
