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.
Claims22
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.
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.
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.
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.
