ABSTRACT:
Methods and apparatus for stacking sheets of various intermixed lengths in a stacking location employ distinct first and second sheet drive rollers at a sheet feed path adjacent said stacking location. The first sheet drive rollers are rotated in a first sense of rotation for driving each sheet along the sheet feed path in a first direction. The second sheet drive rollers are for each of the sheets maintained out of the sheet feed path while the particular sheet is driven with the first sheet drive roller means in the first direction past a stacking position at the stacking location. The second sheet drive rollers are rotated in a second sense of rotation for driving each sheet in a second direction opposed to said first direction. The second sheet drive rollers are for each sheet driven past the stacking location introduced into the sheet feed path for driving the particular sheet in said second direction into the stacking location.
