Abstract
An air folder adjuster (10) includes an air supply (12) and air supply tubing (14) connected to air supply (12) at end (16). The opposite end (18) of air supply tubing (14) is connected to one or more air nozzles (20). In a printing press utilized for folding documents such as books, air folder adjuster (10) is positioned so that air nozzles (20) direct compressed air from air supply (12) downward onto the head (26) of document (24) on either side of chopper arm (34) during the folding process thus ensuring that the document (24) lies flat, square, and untouched during the folding process and thereby allowing the elimination of chopper brushes altogether.
