Sheet feeder has stack stop grid and flap shaft forming functional unit which is movable in sheet feeder at right angles to transporting direction and/or pivotable around straight line extending perpendicularly to transporting direction

摘要

The sheet feeder comprises a stacking plate (3), a sheet separator, a stack stop grid (7) upon which lies the sheet stack by its front side, and a flap shaft (14) connected to the stack stop grid. The stack stop grid and flap shaft form a functional unit which is movable in the sheet feeder at right angles to the transporting direction (11) and/or pivotable around a straight line (A) extending perpendicularly to the transporting direction and intersecting the machine center. The stack stop grid comprises a frame (25) to which are connected a bearing (28) supporting the flap shaft and a flap shaft drive (29).
