In order to perform standard letter folds using a buckle folder, sheets must be fed to the folder short edge first. Since the output from most copiers and electronic printers is long edge first, some type of sheet turning mechanism is necessary if folding is to be done in an on-line, straight-line system. If a right angle sheet transport system is used, everything is turned, and it is no longer possible to use the same folder to fold A3 or other size sheets that are often already oriented short edge first.
