Abstract
A sheet stacking device comprised of a sheet support bed having a first end and a second end. The sheet support bed is comprised of a plurality of side-by-side rollers, each of the rollers being freely rotatable about an associated roller axis. A drive assembly moves the sheet support bed in a predetermined direction along a closed path, the path having a horizontal upper run and a horizontal lower run, and is dimensioned such that a space exists between the first end and the second end of the sheet support bed as the sheet support bed moves along the path. A roller control assembly for selectively and sequentially controlling rotation of select ones of the rollers at select intervals during a stacking operation.
