Abstract

An improved mailer folding apparatus that forms mailers from mailer blanks. The mailer folding apparatus comprises a transport assembly and one or more folding assemblies. The transport assembly moves mailer blanks and/or mailers through the mailer folding apparatus. The one or more folding assemblies may each comprise a folding system and a carriage system. The folding system may selectively allow for the folding of a mailer blank into a mailer. A carriage of the carriage system may move the folding system longitudinally between different positions relative to the transport assembly. An engagement system separate from the carriage system or integrated into the carriage system may engage and disengage the folding system with the transport system for selectively feeding a mailer blank through the folding system, or disengage the folding system for allowing a mailer blank or folded mailer to bypass the folding system.

First claim

What is claimed is:

1. A mailer apparatus comprising:
a transport assembly, wherein the transport assembly moves a mailer blank at a transport speed;
a folding assembly operatively coupled to the transport assembly, wherein the folding assembly comprises:
a carriage system; and
a folding system operatively coupled to the carriage system, the folding system comprising a mailer feeder that moves the mailer blank through the folding system at a feeding speed that is the same as the transport speed of the transport assembly;

wherein the folding assembly receives the mailer blank in a first position;
wherein the carriage system moves the folding system with respect to the transport assembly to a second position at a carriage speed that is the same as the transport speed while the folding system folds the mailer blank into a mailer at a folding speed that is less than the transport speed or while the mailer blank is static within the folding system; and
wherein the carriage system returns the folding system to the first position to receive another mailer blank.

2. The mailer apparatus of claim 1 , wherein the mailer feeder comprises:
one or more feeder rollers;
one or more feeder belts operatively coupled to the one or more feeder rollers; and
one or more feeder drives.

3. The mailer apparatus of claim 1 , wherein the folding assembly further comprises:
an engagement system, wherein the engagement system engages the mailer feeder for receiving the mailer blank and disengages the mailer feeder for allowing the mailer blank to bypass the folding system.

4. The mailer apparatus of claim 1 , wherein the folding system further comprises:
a first folding member; and
a second folding member;
wherein the first folding member receives the mailer blank in a first folding position, actuates between the first folding position to a second folding position to fold the mailer blank around the second folding member.

5. The mailer apparatus of claim 4 , wherein the second folding member comprises a tuck portion with a tuck edge.

6. The mailer apparatus of claim 1 , further comprising:
one or more sealing systems, wherein the one or more sealing systems activate a sealant on one or more blank edges of the mailer blank.

7. The mailer apparatus of claim 6 , wherein the sealant is glue and the one or more sealing systems are one or more glue dispensers that dispense the glue on the one or more blank edges of the mailer blank.

8. The mailer apparatus of claim 6 , further comprising:
one or more securing systems, wherein the one or more securing systems apply pressure to one or more mailer edges of the mailer.

9. The mailer apparatus of claim 8 , wherein the one or more securing systems comprise:
a pair of rollers, wherein the pair of rollers apply pressure to the one or mailer edges of the mailer.

10. The mailer apparatus of claim 1 , further comprising:
one or more sensors, wherein the one or more sensors identify a presence of the mailer blank to activate the folding assembly.

11. The mailer apparatus of claim 1 , wherein the transport assembly comprises a conveyor that moves the mailer blank or the mailer.

12. The mailer apparatus of claim 11 , wherein the conveyor comprises a roller conveyor, a belt conveyor, or a slide conveyor.

13. The mailer apparatus of claim 1 , wherein the folding assembly comprises a first folding assembly comprising a first folding system and a first carriage system, and wherein the mailer apparatus further comprises:
a second folding assembly comprising:
a second carriage system; and
a second folding system operatively coupled to the second carriage system;

wherein the first folding system receives first mailer blanks and folds the first mailer blanks into first mailers and allows second mailer blanks to bypass the first folding system; and
wherein the second folding system receives the second mailer blanks and folds the second mailer blanks into second mailers and allows the first mailers to bypass the second folding system.

14. The mailer apparatus of claim 1 , further comprising:
an adjustment system, wherein the adjustment system adjusts the folding assembly for mailer blanks or mailers of different widths.

15. A mailer apparatus comprising:
a transport assembly, wherein the transport assembly moves mailer blanks or mailers;
a first folding assembly operatively coupled to the transport assembly, wherein the first folding assembly comprises a first folding system; and
a second folding assembly operatively coupled to the transport assembly, wherein the second folding assembly comprises a second folding system;
wherein the first folding system receives first mailer blanks and folds the first mailer blanks into first mailers and allows second mailer blanks to bypass the first folding system; and
wherein the second folding system receives the second mailer blanks and folds the second mailer blanks into second mailers and allows the first mailers to bypass the second folding system.

16. A method of forming mailers using a mailer machine, the method comprising:
moving mailer blanks using a transport assembly operatively coupled to a first folding system and a second folding system;
receiving first mailer blanks at the first folding system, wherein the first folding system folds the first mailer blanks into first mailers and allows second mailer blanks to bypass the first folding system; and
receiving the second mailer blanks at the second folding system, wherein the second folding system folds the second mailer blanks into second mailers and allows the first mailers to bypass the second folding system.

17. The method of claim 16 , wherein the mailers are formed by:
moving the mailer blanks using a transport assembly;
receiving the mailers blanks at a folding assembly operatively coupled to the transport assembly, wherein the folding assembly comprises:
a carriage system; and
a folding system operatively coupled to the carriage system; and
wherein the folding assembly receives a mailer blank in a first position, the carriage system moves the folding system with respect to the transport assembly to a second position, the folding system folds the mailer blank into a mailer, and the carriage system returns the folding system to the first position.

18. A method of forming mailers using a mailer machine, the method comprising:
moving a mailer blanks using a transport assembly at a transport speed;
receiving the mailers blanks at a folding assembly operatively coupled to the transport assembly, wherein the folding assembly comprises:
a carriage system; and
a folding system operatively coupled to the carriage system, the folding system comprising a mailer feeder that moves a mailer blank through the folding system at a feeding speed that is the same as the transport speed of the transport assembly; and
wherein the folding assembly receives the mailer blank in a first position;
wherein the carriage system moves the folding system with respect to the transport assembly to a second position at a carriage speed that is the same as the transport speed while the folding system folds the mailer blank into a mailer at a folding speed that is less than the transport speed or while the mailer blank is static within the folding system; and
wherein the carriage system returns the folding system to the first position to receive another mailer blank.
