Laminating system with coded film cartridge

1. A dual roll laminating film cartridge comprising:

a body defining a first end supporting a first end of a first roll of continuous translucent laminating film and a first end of a second roll of continuous translucent laminating film, the body further defining a second end supporting a second end of the first roll and a second end of the second roll, wherein facing surfaces of the films extended from the first and second rolls in an advancing direction are coated with a heat-activated adhesive;

a bridge extending between the first and second ends of the body at a position between the first and second rolls, the bridge defining an article chute for the reception of articles to be laminated by the films of the first and second rolls; and

a code indicative of one or more characteristics of the film of the first and second rolls, the code comprising a predetermined flag pattern established by the selective presence of coding tabs that project outward from the body along a plurality of prescribed positions arranged in a row.

2. The dual roll laminating film cartridge claim 1 , further comprising a handle provided at a top edge of the cartridge.

3. The dual roll laminating film cartridge claim 1 , wherein the predetermined flag pattern is coded to identify a material thickness of the films of the first and second rolls.

4. The dual roll laminating film cartridge claim 3 , wherein the predetermined flag pattern is further coded to identify a film dimension perpendicular to a rolled length of film on the first and second rolls.

5. The dual roll laminating film cartridge of claim 1 , wherein the predetermined flag pattern includes at least one coding tab on the first end of the body and at least one coding tab on the second end of the body.

6. The dual roll laminating film cartridge of claim 5 , wherein the at least one coding tab on the first end of the body and the at least one coding tab on the second end of the body extend outward in opposite directions, outboard of the respective first and second ends of the first and second rolls.

7. The dual roll laminating film cartridge of claim 5 , wherein the at least one coding tab on the first end of the body is positioned within a first concavity formed by a first pair of spaced walls, and wherein the at least one coding tab on the second end of the body is positioned within a second concavity formed by a second pair of spaced walls.

8. The dual roll laminating film cartridge of claim 1 , wherein the first roll is a top roll and the second roll is a bottom roll, the body defining a first foot at a bottom of the first end and a second foot at a bottom of the second end, wherein the predetermined flag pattern is positioned adjacent the first and second feet.

9. The dual roll laminating film cartridge of claim 1 , wherein the film of one of the first and second rolls includes an end of roll indicator embedded therein or provided by a label thereon.

10. The dual roll laminating film cartridge of claim 9 , wherein the end of roll indicator is provided by a reflective sticker.

11. The dual roll laminating film cartridge of claim 1 , wherein the bridge is a separate piece from the body.

12. The dual roll laminating film cartridge of claim 11 , wherein the bridge is made of a material having a flexural strength greater than a material of the body.

13. The dual roll laminating film cartridge of claim 11 , wherein the bridge is secured to the body by a snap connection.

14. The dual roll laminating film cartridge of claim 13 , wherein the body includes a keyway into which the bridge is received for the snap connection.

15. The dual roll laminating film cartridge of claim 1 , wherein the article chute defined by the bridge includes spaced apart upper and lower walls configured such that the article chute has a wider inlet end and a narrower outlet end.

16. The dual roll laminating film cartridge of claim 1 , wherein the first roll is a top roll and the second roll is a bottom roll, the body defining opposed end plates and a lower cross member spanning between lower ends of the end plates below the bottom roll.

17. The dual roll laminating film cartridge of claim 1 , further comprising a heat shield to block the rolls from heat generated by a laminating machine in which the cartridge is used.

18. The dual roll laminating film cartridge of claim 1 , wherein the coding tabs project outward from the body in a direction parallel to a longitudinal direction of the rolls.

19. A dual roll laminating film cartridge comprising:

a body defining a first end supporting a first end of a first roll of continuous translucent laminating film and a first end of a second roll of continuous translucent laminating film, the body further defining a second end supporting a second end of the first roll and a second end of the second roll, wherein facing surfaces of the films extended from the first and second rolls in an advancing direction are coated with a heat-activated adhesive;

a bridge extending between the first and second ends of the body at a position between the first and second rolls, the bridge defining an article chute for the reception of articles to be laminated by the films of the first and second rolls; and

a code indicative of one or more characteristics of the film of the first and second rolls, the code comprising a predetermined flag pattern of coding tabs that project outward from the body;

wherein the predetermined flag pattern of coding tabs includes frangible coding tabs for coding the cartridge by selectively being broken off or left intact.

20. The dual roll laminating film cartridge claim 19 , wherein the predetermined flag pattern of coding tabs is coded to identify a material thickness of the films of the first and second rolls, a film dimension perpendicular to a rolled length of film on the first and second rolls, or both.
