Envelope turning and aligning apparatus

Apparatus for turning and aligning flat articles, comprising:

• a first conveyor for transporting flat articles horizontally from an upstream to a downstream position;
• a second conveyor oriented at a 90 degree angle relative to said first conveyor, said second conveyor having an upstream and a downstream end, wherein said upstream end of said second conveyor is situated adjacent said downstream end of said first conveyor, said second conveyor situated to receive said flat articles from said first conveyor;
• a pivoting device located on one side of said second conveyor for engaging a side of said flat articles;
• and
• a third conveyor having an upstream end located adjacent the downstream end of said second conveyor, said third conveyor having a flat deck, a first angled roller extending just above said flat deck, a registration wall on one side of said flat deck, and a normal force sphere mounted above said angled roller, wherein said angled roller and said sphere drive said flat articles downstream and against said registration wall and said registration wall extends along said second conveyor, and said pivoting device includes the upstream end of said registration wall.
