Abstract

Abstract The instant invention provides sheet stacking apparatus capable of stacking bundles of aligned sheets of paper in alternate, offset relation or alternate, skewed relation. The apparatus includes a storage bin for receiving a multiplicity of aligned bundles of sheets. The storage bin includes a bottom wall, a pair of side walls, front stopping members adjacent each of the side walls, and an adjustable, central post situated between the front stopping members. The apparatus also includes means for feeding the aligned bundles of sheets along alternate side walls of the storage bin. The post may be positioned closer than the front stopping members to said feeding means to effect alternate offset stacking or further away than the front stopping members from said feeding means to effect alternate skewed stacking.
