Front end conveyor with chad wall

A front end conveyor having an upstream end and a downstream end, the front end conveyor comprising:

• a frame having a first side and a second side;
• a lower deck including a plurality of sheet supports, upper portions of the sheet supports lying in a first plane;
• an upper deck including a plurality of sheet guides, the plurality of sheet supports and the plurality of sheet guides defining therebetween a sheet transport path for moving sheets in a sheet transport direction toward the downstream end of the front end conveyor, and
• a chad wall extending transversely to the sheet transport direction, the chad wall having a top edge located below the sheet transport path and a front surface facing in the upstream direction,
• wherein the top edge of the chad wall is positioned relative to the sheet transport path such that hanging chads depending from the sheets will impact the chad wall, and
• wherein the chad wall is mounted to the frame such that a distance from the top edge of the chad wall to the sheet transport path is adjustable,
• wherein the chad wall includes a plurality of slots extending through the front surface, each of the plurality of slots including a first end and a second end,
• wherein the frame includes a plurality of projections extending through the plurality of slots, and
• wherein chad wall is configured to be slid from an uppermost position relative to the sheet transport path in which the projections are located at the first ends of the plurality of slots to a lowermost position relative to the sheet transport path in which the projections are located at the second ends of the plurality of slots.
