Abstract

A machine for distributing blowing insulation material is provided. The machine includes a chute having an inlet portion and an upper portion. The inlet portion is configured to receive a package of compressed loosefill insulation material. The upper portion extends from the inlet portion. The inlet portion and the upper portion have cross-sectional shapes and sizes that closely correspond to a cross-sectional shape and size of the package of compressed loosefill insulation material. A lower unit is configured to receive the loosefill insulation material exiting the chute. The lower unit includes a plurality of shredders and a discharge mechanism. The discharge mechanism is configured to discharge conditioned loosefill insulation material into an airstream. The cross-sectional shape and size of the inlet portion and the upper portion are configured to direct an expansive force of the compressed loosefill insulation material in a direction toward the lower unit.

First claim

What is claimed is:

1. A machine for distributing blowing insulation material from a package of compressed loosefill insulation material, the machine comprising:
a chute having an inlet portion an upper portion and a throat portion, the inlet portion configured to receive the package of compressed loosefill insulation material, the package having compressed loosefill insulation material within an outer protective covering, the inlet portion having a width and further having a vertically oriented, rectangular cross-sectional shape and size, the upper portion extending in a horizontal direction from the inlet portion to a sidewall and in a vertical direction from a top wall to the throat portion, and the upper portion having a vertically oriented, rectangular cross-sectional shape and size that closely corresponds to a vertically oriented, rectangular cross-sectional shape and size of the package of compressed loosefill insulation material, the upper portion further having a width and the throat portion of the chute having a width, and wherein the inlet portion, upper portion and throat portion define the flow of the compressed loosefill insulation material and the widths of the inlet portion, upper portion and throat portion are equal to each other, the chute further including a cutting mechanism configured to cut the outer covering of the package; and
a lower unit configured to receive the compressed loosefill insulation material exiting the package and the chute, the lower unit including a plurality of shredders and a discharge mechanism, the discharge mechanism configured to discharge conditioned loosefill insulation material into an airstream;
wherein the vertically oriented, rectangular cross-sectional shape and size of the inlet portion and the upper portion direct an expansive force of the compressed loosefill insulation material in a direction toward the lower unit.

2. The machine of claim 1 , wherein the cross-sectional shape of the inlet portion is a rectangle having rounded corners.

3. The machine of claim 1 , wherein the cross-sectional shape of the upper portion is a rectangle having rounded corners.

4. The machine of claim 1 , wherein opposing longitudinal walls forming the inlet portion have a vertical orientation and opposing lateral walls forming the inlet portion have a horizontal orientation.

5. The machine of claim 4 , wherein the package of compressed loosefill insulation material has a width of 8.0 inches and a height of 19.0 inches.

6. The machine of claim 1 , wherein the package of compressed loosefill insulation material is is packaged with a compression ratio of at least about 10:1.

7. A machine for distributing blowing insulation material from a package of compressed loosefill insulation material, the machine comprising:
a chute having an inlet portion, an upper portion and a throat portion, the inlet portion configured to receive the package of compressed loosefill insulation material, the package having compressed loosefill insulation material within an outer protective covering, the inlet portion having a width and further having a vertically oriented, rectangular cross-sectional shape and size, the upper portion extending in a horizontal direction from the inlet portion to a sidewall and in a vertical direction from a top wall to the throat portion, and the upper portion having a vertically oriented, rectangular cross-sectional shape and size that closely corresponds to a vertically oriented, rectangular cross-sectional shape and size of the package of the compressed loosefill insulation material, the upper portion further having a width and the throat portion of the chute having a width, and wherein the inlet portion, upper portion and throat portion define the flow of the compressed loosefill insulation material and the widths of the inlet portion, upper portion and throat portion are the same dimensions, the chute further including a cutting mechanism configured to cute the outer covering of the package; and
a lower unit configured to receive the compressed loosefill insulation material exiting package and the chute, the lower unit including a plurality of shredders and a discharge mechanism, the discharge mechanism configured to discharge conditioned loosefill insulation material into an airstream;
wherein the vertically oriented, rectangular cross-sectional shape and size of the inlet portion and the upper portion direct an expansive force of the compressed loosefill insulation material in a direction toward the lower unit.

8. The machine of claim 7 , wherein the cross-sectional shape of the inlet portion is a rectangle having rounded corners.

9. The machine of claim 7 , wherein the cross-sectional shape of the throat portion is a rectangle having rounded corners.

10. The machine of claim 7 , wherein opposing longitudinal walls forming the inlet portion have a vertical orientation and opposing lateral walls forming the inlet portion have a horizontal orientation.

11. The machine of claim 10 , wherein the package of compressed loosefill insulation material has a width of 8.0 inches and a height of 19.0 inches.

12. The machine of claim 7 , wherein the package of compressed loosefill insulation material is is packaged with a compression ratio of at least 10:1.
