CLAIMS

What is claimed is:

1. A method of manufacturing a baffle tape, the method comprising:

providing a plurality of adhesive webs, each adhesive web comprising a hot melt adhesive adhered to a backing material;

providing a fabric web comprising a fabric material;

guiding a first adhesive web from the plurality of adhesive webs into a first position proximate a first side of the fabric web;

guiding a second adhesive web from the plurality of adhesive webs into a second position proximate a second side of the fabric web;

applying heat and pressure to form a web of the baffle tape comprising the first adhesive web bonded to the first side of the fabric web and the second adhesive web bonded to the second side of the fabric web; and

rewinding the web of the baffle tape into a roll.

2. The method of claim 1, wherein providing the plurality of adhesive webs comprises unwinding at least one roll of adhesive material comprising the hot melt adhesive adhered to the backing material.

3. The method of claim 1, wherein providing the plurality of adhesive webs comprises slitting an initial adhesive web into the plurality adhesive webs.

4. The method of claim 1, wherein providing the fabric web comprises unwinding a roll of the fabric material.

5. The method of claim 1, wherein providing the fabric web comprises slitting an initial fabric web into a plurality of fabric webs comprising the fabric web.

6. The method of claim 1, wherein guiding the first adhesive web comprises directing the first adhesive web into a first lateral location, and guiding the second adhesive web comprises directing the second adhesive web into a second lateral location different from the first lateral location.

7. The method of claim 1, wherein guiding the first adhesive web comprises flipping the first adhesive web, such that the hot melt adhesive of the first adhesive web is positioned between the fabric web and the backing material of the first adhesive web.

8. The method of claim 1, wherein the baffle tape comprises the first adhesive web positioned proximate an edge of the fabric web and the second adhesive web positioned proximate an opposite edge of the fabric web.

9. The method of claim 1, wherein the applying step comprises passing the first adhesive web, the fabric web, and the second adhesive web through a nip of a belt lamination machine.

10. The method of claim 1, further comprising:

cutting the baffle tape into a plurality of adhesive strips;

placing the plurality of adhesive strips in a predetermined arrangement between a first fabric sheet and a second fabric sheet;

applying heat and pressure to (i) bond the plurality of adhesive strips to the first fabric sheet and the second fabric sheet and (ii) form a plurality of baffles connecting the first fabric sheet and the second fabric sheet,

wherein each baffle comprises a non-bonded portion of one of the plurality of adhesive strips.

11. The method of claim 10, wherein the predetermined arrangement comprises the plurality of adhesive strips in a substantially parallel and spaced-apart arrangement.

12. The method of claim 10, wherein each adhesive strip from the plurality of adhesive strips comprises a Z-shaped cross section.

13. The method of claim 10, wherein the first and second fabric sheets and two adjacent baffles define an insulation chamber.

14. The method of claim 13, further comprising filling the insulation chamber with an insulating material.

15. The method of claim 10, further comprising removing the backing material from the plurality of adhesive strips prior to placing the plurality of adhesive strips in the

predetermined arrangement.

16. The baffle tape manufactured according to the method of claim 1.

17. An insulated panel manufactured according to the method of claim 14.

18. A system for manufacturing a baffle tape, the system comprising:

a plurality of adhesive webs comprising a hot melt adhesive adhered to a backing material;

a fabric web comprising a fabric material;

a plurality of rollers for (i) guiding a first adhesive web from the plurality of adhesive webs into a first position proximate a first side of the fabric web and (ii) guiding a second adhesive web from the plurality of adhesive webs into a second position proximate a second side of the fabric web;

at least one laminator for applying heat and pressure to form a web of the baffle tape comprising the first adhesive web bonded to the first side of the fabric web and the second adhesive web bonded to the second side of the fabric web; and

a rewinder for rewinding the web of the baffle tape into a roll.

19. The system of claim 18, further comprising at least one roll of adhesive material for providing the plurality of adhesive webs.

20. The system of claim 18, further comprising a slitter for slitting an initial adhesive web into the plurality of adhesive webs.

21. The system of claim 18, further comprising at least one roll of fabric for providing the fabric web.

22. The system of claim 18, further comprising a slitter for slitting an initial fabric web into a plurality of fabric webs comprising the fabric web.

23. The system of claim 18, wherein the plurality of rollers are configured to (i) direct the first adhesive web into a first lateral location and (ii) direct the second adhesive web into a second lateral location different from the first lateral location.

24. The system of claim 18, wherein the plurality of rollers are configured to flip the first adhesive web, such that the hot melt adhesive of the first adhesive web is positioned between the fabric web and the backing material of the first adhesive web.

25. The system of claim 18, wherein the baffle tape comprises the first adhesive web positioned proximate an edge of the fabric web and the second adhesive web positioned proximate an opposite edge of the fabric web.

26. The system of claim 18, wherein the at least one laminator comprises a belt lamination machine.
