Abstract

A system for transporting insulation particles suitable for use in a process for forming an insulation product is provided, comprising: a blowing machine for forming an insulation particle/air suspension, wherein the blowing machine comprises at least one opening, and a hose in communication with the at least one opening, for transporting the suspension to or from the blowing machine, wherein the internal diameter variation of at least a portion of the hose is less than about 0.20 inch.

Claims (26)

1. A system for transporting insulation particles suitable for use in a process for forming an insulation product, comprising:

a blowing machine for forming an insulation particle/air suspension, wherein the blowing machine comprises at least one opening, and

a flexible hose, in communication with the at least one opening, for transporting the suspension from the blowing machine to proximate the surface to be insulated, wherein the internal diameter variation of at least a portion of the flexible hose amounting to at least about 25% of the length of the flexible hose is less than about 0.20 inch to increase the velocity of the suspension as the suspension exits the flexible hose, the flexible hose comprising a plurality of wall sections joined together, an exterior of the flexible hose comprising a supporting structure of one or more of spaced apart reinforcing rings or helical structure that project outwardly from other exterior portions of the flexible hose.

2. The system of claim 1 , wherein the internal diameter variation of at least the portion of the flexible hose is less than about 0.17 inch.

3. The system of claim 1 , wherein the internal diameter variation of at least the portion of the flexible hose is less than about 0.14 inch.

4. The system of claim 1 , wherein the internal diameter variation of at least the portion of the flexible hose is less than about 0.10 inch.

5. The system of claim 1 , wherein the internal diameter variation of at least the portion of the flexible hose is less than about 0.08 inch.

6. The system of claim 1 . wherein the insulation particles are fibrous nodules.

7. The system of claim 1 , wherein the length of the portion of the flexible hose is at least about 50% of the total length of the hose.

8. The system of claim 1 , wherein the length of the portion of the flexible hose is at least about 75% of the total length of the hose.

9. The system of claim 1 , wherein a second flexible hose is connected to the blowing machine to transport recyclable material to the blowing machine.

10. A system for transporting insulation particles suitable for use in a process for forming an insulation product, comprising:

a blowing machine for forming an insulation particle/air suspension, wherein the blowing machine comprises at least one opening, and

a flexible hose in communication with the at least one opening, for transporting the suspension from the blowing machine to proximate the surface to be insulated, wherein the internal diameter variation of at least about 25% of the length of the flexible hose is less than about 0.20 inch to increase the velocity of the suspension as the suspension exits the flexible hose, the flexible hose comprising a plurality of wall sections joined together, an exterior of the flexible hose comprising a supporting structure of one or more of spaced apart reinforcing rings or helical structure that project outwardly for other exterior portions of the flexible hose.

11. The system of claim 10 . wherein a second flexible hose is connected to the blowing machine to transport recyclable material to the blowing machine.

12. A method at transporting insulation particles suitable for use in a process for forming an insulation product, comprising transporting an insulation particle/air suspension formed by a blowing machine through a flexible hose, wherein the internal diameter variation of at least a portion of the flexible hose amounting to at least about 25% of the length of the flexible hose is less than about 0.20inch to increase the velocity of the suspension as the suspension exits the flexible hose, the flexible hose comprising a plurality of wall sections joined together, an exterior of the flexible hose comprising a supporting structure of one or more of spaced apart reinforcing rings or helical structure that project outwardly or other exterior portions of the flexible hose.

13. The method of claim 12 , wherein the internal diameter variation of at least the portion of the flexible hose is less than about 0.17 inch.

14. The method of claim 12 , wherein the internal diameter variation of at least the portion of the flexible hose is less than about 0.14 inch.

15. The method of claim 12 , wherein the internal diameter variation of at least the portion of the flexible hose is less than about 0.10 inch.

16. The method of claim 12 , wherein the internal diameter variation of at least the portion of the flexible hose is less than about 0.08 inch.

17. The method of claim 12 , wherein the insulation particles are fibrous nodules.

18. The method of claim 12 , wherein the length of the portion of the flexible hose is at least about 50% of the total length of the flexible hose.

19. The method of claim 12 , wherein the length of the portion of the flexible hose is at least about 75% of the total length of the hose.

20. The method of claim 12 , wherein a second flexible hose is connected to the blowing machine to transport recyclable material to the blowing machine.

21. A method of transporting insulation particles suitable for use in a process for forming an insulation product, comprising transporting an insulation particle/air suspension formed by a blowing machine through a flexible hose, wherein the internal diameter variation of the flexible hose is less than about 0.20 inch over at least about 25% of the length of the flexible hose, the flexible hose comprising a plurality of wall sections joined together, an exterior of the flexible hose comprising a supporting structure of one or more of spaced apart reinforcing rings or helical structure that project outwardly for other exterior portions of the flexible hose.

22. The method of claim 21 , wherein a second flexible hose is connected to the blowing machine to transport recyclable material to the blowing machine.
