Abstract

An insulation system comprising: a supply of material having discrete elements; an applicator assembly for installation of the material having discrete elements to a surface; and a scrubber for finishing the face of the material, the scrubber including: (a) a vacuum conduit; (b) a blade assembly attached to the vacuum conduit; (c) a drive for the blade assembly; and (d) a vacuum substantially adjacent the face of the material during finishing. In the one embodiment, the system comprises a transporter system downstream of the supply of material having discrete elements for delivery of the material to the applicator assembly. Also, in one embodiment, the blade assembly comprises an axis of rotation perpendicular to the face of the material during finishing.

Claims (37)

1. An insulation system comprising:

(a) a supply of insulating material having discrete elements;

(b) an adhesive applicator assembly for installation of the material having discrete elements to a surface;

(c) a transporter system downstream of the supply of material having discrete elements for delivery of the material to the applicator assembly; and

(d) a scrubber for finishing the face of the material, the scrubber including: (i) a vacuum conduit; (ii) a blade assembly attached to the vacuum conduit, the blade assembly comprising an axis of rotation substantially perpendicular to the face of the material during finishing, said blade assembly including a plurality of blades extending outwardly from the axis of rotation and to a planar blade attached to distal ends of said plurality of blades; (iii) a drive for the blade assembly; and (iv) a vacuum substantially adjacent the face of the material during finishing.

2. The insulation system according to claim 1 , wherein, the transporter system includes a conduit with an inlet and outlet; and an air supply to move the material having discrete elements through the conduit.

3. The insulation system according to claim 2 , wherein the transporter system further includes a debailer for debailing bundles of the material having discrete elements.

4. The insulation system according to claim 1 , wherein the supply of material having discrete elements is selected from the group consisting of fibrous material, granular material, pellet material, agglomerated material, aggregated material and mixtures thereof.

5. The insulation system according to claim 1 , wherein the supply of material having discrete elements is inorganic.

6. The insulation system according to claim 5 , wherein the inorganic material is selected from the group consisting of fiberglass, rock wool, pearlite, mineral wool, asbestos, and mixtures thereof.

7. The insulation system according to claim 1 , wherein the supply of material having discrete elements is organic.

8. The insulation system according to claim 7 , wherein the organic material is a natural material.

9. The insulation system according to claim 8 , wherein the natural material is cellulosic.

10. The insulation system according to claim 1 , wherein the supply of material having discrete elements is a non-conductive material.

11. The insulation system according to claim 10 , wherein the supply of non-conductive material is a thermally non-conductive material.

12. The insulation system according to claim 10 , wherein the supply of non-conductive material is an acoustically non-conductive material.

13. The insulation system according to claim 10 , wherein the supply of non-conductive material is an electrically non-conductive material.

14. The insulation system according to claim 10 , wherein the supply of material comprises material that has been reclaimed and recycled through the insulation system.

15. The insulation system according to claim 1 , wherein the applicator assembly includes: a nozzle having an inlet for receiving the material and an outlet for applying the material to a surface; and an adhesive applicator adjacent to the nozzle for activating a substantially water-free adhesive to provide structure to the material having discrete elements during installation.

16. The insulation system according to claim 15 , wherein the adhesive applicator includes a supply of adhesive material and a spray head for supplying adhesive to the material having discrete elements.

17. The insulation system according to claim 16 , wherein the supply of adhesive material includes a hot melt adhesive and a heater assembly.

18. The insulation system according to claim 17 , wherein the hot melt adhesive is a thermoplastic adhesive.

19. The insulation system according to claim 1 , wherein the vacuum conduit includes at least one inlet and at least one outlet.

20. The insulation system according to claim 19 , wherein the open area of the inlet is greater than the open area of the outlet.

21. The insulation system according to claim 19 , further including a transition zone between the inlet and the outlet.

22. The insulation system according to claim 1 , wherein the blade assembly has contact surface substantially parallel to the face of the material during finishing.

23. The insulation system according to claim 22 , wherein the axis of rotation of the blade assembly is substantially perpendicular to the face of the material during finishing.

24. The insulation system according to claim 1 , wherein the blade assembly includes scalloped edges.

25. The insulation system according to claim 1 , wherein the blade assembly includes sidewall cutters.

26. The insulation system according to claim 1 , wherein the blade assembly includes an elastomeric surface.

27. The insulation system according to claim 1 , wherein the blade assembly includes an angled edge.

28. The insulation system according to claim 1 , wherein the drive is an external drive.

29. The insulation system according to claim 28 , wherein the drive is a belt drive.

30. The insulation system according to claim 29 , wherein the drive is a timing belt drive.

31. The insulation system according to claim 1 , further including a positioner attached to the vacuum conduit for moving the apparatus with respect to the face of the material.

32. The insulation system according to claim 31 , wherein the positioner includes at least one handle.

33. The insulation system according to claim 1 , wherein the vacuum includes a vacuum source attached to the vacuum for removing loose material created during finishing.
