Abstract
A high capacity, high reliability cassette tray sheet feeding assembly 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 high capacity, high reliability cassette tray sheet feeding assembly includes a cassette frame for removing and reinstalling into a sheet supply station of the sheet using machine. The cassette frame has a front end over which sheets are fed into the machine, and a forward feed corner snubber that is mounted to one corner of the front end of the cassette frame for preventing the feeding of multiple sheets at a time. The cassette frame includes a fixed position stationary base plate within the cassette frame for supporting a high capacity stack of sheets having a topmost sheet. The high capacity, high reliability cassette tray sheet feeding assembly further includes a variable position sheet receiving path, and a pivotable feed wheel assembly for reliably feeding topmost sheets seriatim from the fixed position stationary base plate into the variable position sheet path. The pivotable feed wheel assembly has a first position for a full stack of sheets, and a second position for an empty base plate. Importantly, the pivotable feed wheel assembly has a constant sheet feeding angle, and a constant sheet feeding normal force, for enabling continuous high reliability feeding of sheets from the first through to the second position thereof.
