A stacking apparatus for stacking a plurality of flat articles on edge is provided that receives articles in an article receiver that includes a stop wall to receive the front edge of each article and stop horizontal motion of the article and a rotatable segmented roller for receiving the bottom edge of each article. The segmented roller is rotatable about a central axis of the cylinder and includes a planar surface, the planar surface receiving the bottom edge of each flat article when the planar surface is in a horizontal position. The segmented roller is rotatable from a stopped position wherein the planar surface is in the horizontal position to form a gap to receive the bottom edge of one article at a time to a rotating configuration wherein the cylindrical outer surface of the segmented roller drives the one article against a stacking conveyor bed.
