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.
Claims18
A printing system for creating folded documents from a document with a leading end, a middle, and a trailing end, including an air folder adjuster apparatus, the apparatus comprising:
- a) an air supply;
- b) an air supply regulator connected to said air supply;
- c) air supply tubing with two ends, with one end connected to said air supply regulator;
- d) at least one directional air nozzle connected to the other end of said air supply tubing;
- and
- e) a remote head stop air stand wherein said second end of said air supply tubing is connected to said remote head stop air stand and said at least one directional air nozzle is also connected to said remote head stop air stand and wherein said remote head stop air stand is moveably connected to said printing system such that said at least one directional air nozzle is directed down from the printing system at the leading end of the document, wherein the leading end of the document is at the head stop, and in the direction of an approximate longitudinal center of at least one of a pair of folding rollers.
A printing system for creating folded documents from a document with a leading end, a middle, and a trailing end, the printing system including a head stop, a pair of folding rollers and a chopper arm, and an air folder adjuster apparatus, the apparatus comprising:
- a) an air supply;
- b) a control stand;
- c) at least one air control valve, with an inlet end and an outlet end, connected to the control stand wherein the air supply is connected to the inlet end of the at least one air control valve;
- d) an air flow control handle connected to the air flow control valve for controlling the amount of air flowing through the air flow control valve;
- e) air supply tubing with two ends, with one end connected to the outlet end of the air control valve;
- f) a remote head stop air stand connected to the head stop and to the second end of the air supply tubing;
- and
- g) at least two air nozzles connected to the remote head stop air stand directed downward from said head stop at the leading end of the document, wherein the leading end of the document is at the head stop, and on either side of said chopper arm toward an approximate longitudinal center of each of the folding rollers.
A printing system for creating folded documents from a document with a leading end, a middle, and a trailing end, the printing system including a head stop, a pair of folding rollers and a chopper arm, and an air folder adjuster method, the method comprising the steps of:
- a) providing an air supply;
- b) providing a control stand;
- c) connecting at least one air control valve, with an inlet end and an outlet end, to the control stand;
- d) connecting the air supply to the inlet end of the air control valve;
- e) connecting an air flow control handle to the air flow control valve for controlling the amount of air flowing through the air flow control valve;
- f) providing air supply tubing with two ends and connecting one end of the air supply tubing to the outlet end of the at least one air control valve;
- g) connecting a remote head stop air stand to the head stop;
- h) connecting the second end of the air supply tubing to the remote head stop air stand;
- and
- i) connecting at least two air nozzles to the remote head stop air stand and directing the nozzles downward from said head stop at the leading end of the document, wherein the leading end of the document is at the head stop, and on either side of the chopper arm toward an approximate longitudinal center of each of the folding rollers.
