FIG. 2 , thelow speed shredders 24 are mounted in thelower unit 12 at theoutlet end 18 of thechute 14. Thelow speed shredders 24 are configured to shred and pick apart the blowing insulation as the blowing insulation is discharged from theoutlet end 18 of thechute 14 into thelower unit 12. Although the disclosed blowinginsulation machine 10 is shown with a plurality oflow speed shredders 24, any type of separator, such as a clump breaker, beater bar or any other mechanism that shreds and picks apart the blowing insulation can be used. - As further shown in
FIG. 2 , anagitator 26 is provided for final shredding of the blowing insulation and for preparing the blowing insulation for distribution into an airstream. Adischarge mechanism 28 is positioned downstream from theagitator 26 to distribute the shredded blowing insulation into the airstream. Thedischarge mechanism 28 can be a rotary valve, or any other mechanism including staging hoppers, metering devices, rotary feeders, sufficient to distribute the shredded blowing insulation into an airstream. The shredded blowing insulation is driven through thedischarge mechanism 28 and through amachine outlet 32 by an airstream provided by a blower (not shown) mounted in thelower unit 12. - The
shredders 24,agitator 26 and thedischarge mechanism 28 are mounted for rotation. They can be driven by any suitable means, such as by amotor 34, or any other means sufficient to drive rotary equipment. Alternatively, each of theshredders 24,agitator 26, anddischarge mechanism 28 can be provided with its own motor. - In general, the
chute 14 guides the blowing insulation to thelow speed shredders 24 which shred and pick apart the blowing insulation. The shredded blowing insulation drops from thelow speed shredders 24 into theagitator 26. Theagitator 26 prepares the blowing insulation for distribution into an airstream by further shredding the blowing insulation. The finely shredded blowing insulation drops from theagitator 26 into thedischarge mechanism 28 for distribution into the airstream caused by the blower. The airstream, with the shredded blowing insulation, exits themachine 10 at themachine outlet 32 and flows through adistribution hose 46, as shown inFIG. 3 , toward the insulation cavity, not shown. - In one embodiment as shown in
FIG. 3 , thechute 14 has a substantially rectangular cross-sectional shape that approximates the substantially rectangular cross-sectional shape of apackage 70 of compressed blowing insulation. In one embodiment, thepackage 70 has a height of about 8 inches, a width of about 19 inches and a length of about 38 inches. Such apackage 70 might have a weight of about 35 pounds, although thepackage 70 can weigh more or less than 35 pounds. In this embodiment, thechute 14 has a substantially rectangular cross-section shape of about 9 inches by 20 inches. The substantially rectangular cross-sectional shape of thechute 14 allows thepackage 70 to be easily received and fed through thechute 14 and to be engaged by thelow speed shredders 24. - As shown in
FIG. 4 , thepackage 70 of compressed blowing insulation includes abag 74 that encapsulates a body of compressed blowing insulation. Thebag 74 is made of a polymeric material, such as polyethylene, although any type of material suitable for maintaining the blowing insulation in the desired compression can be used. Thebag 74 provides a waterproof barrier against water, dirt and other deleterious effects. By using a polymeric material for thebag 74, the compressed blowing insulation will be protected from the elements during transportation and storage of thepackage 70. - The compressed blowing insulation in the
package 70 can be any loosefill insulation, such as a multiplicity of discrete, individual tufts, cubes, flakes, or nodules. The blowing insulation can be made of glass fibers or other mineral fibers, and can also be organic fibers or cellulose fibers. Typically, the loosefill insulation is made of glass fibers although other insulation materials such as rock wool, mineral fibers, organic fibers, polymer fibers, inorganic material, and cellulose fibers. Other particulate matter, such as particles of foam, may also be used. Combinations of any of the aforementioned materials are another alternative. - The blowing insulation can have a binder material applied to it, or it can be binderless. The blowing insulation in the
package 70 is compressed to a compression ratio of at least 10:1, which means that the unconstrained blowing insulation, after thebag 74 is opened, has a volume of 10 times that of the compressed blowing insulation in thebag 74. Other compression ratios higher or lower than 10:1 can be used. - In one embodiment as shown in
FIG. 4 , thepackage 70 includes a body of the compressed blowing insulation encapsulated by abag 74. Aslit 76 extends through the body of compressed blowing insulation and thebag 74 and partially divides thepackage 70. In one embodiment, theslit 76 is disposed along the length of thepackage 70 such that the slit divides thepackage 70 into approximately equal size half packages 71 as shown inFIG. 5 . In another embodiment, thepackage 70 can include multiple slits positioned along the length of thepackage 70. In this embodiment, the slits divide thepackage 70 into multiple package segments (not shown). For example, apackage 70 having three slits would be divided into four package segments. Each package segment includes a body of compressed blowing insulation encapsulated by thebag 74. Each package segment is capable is being fed into the blowinginsulation machine 10. - As further shown in
FIGS. 4 and 5 , theslit 76 is configured to be substantially perpendicular to the length of thepackage 70. A substantiallyperpendicular slit 76 enables the machine user to readily cut the un-cut portion of thepackage 70 along a suggestedcut line 79. Cutting thepackage 70 along the suggestedcut line 79 ensures that the resulting half packages 71 are capable of being readily fed into themachine 10. However, it should be understood that theslit 76 can be an angled relative to the length of thepackage 70 and that the angle of theslit 76 relative to the length of thepackage 70 is not important to the operation of thepackage 70. - In this embodiment, the
package 70 has a length and width which define amajor face 80 of thepackage 70 as shown inFIG. 4 . Theslit 76 is positioned along the width of themajor face 80 and extends approximately one-half of the width of thepackage 70. Alternatively, theslit 76 can extend any width of thepackage 70, up to a maximum of ⅞ of the width of thepackage 70. - The
slit 76 enables the machine user to divide thepackage 70 intohalf packages 71 by cutting thepackage 70 along a suggestedcut line 79 as shown inFIGS. 4 and 5 . As shown inFIG. 4 , the suggestedcut line 79 is defined as the un-cut portion of thepackage 70 taken along a Plane P defined by theslit 76. In one embodiment, the machine user cuts thepackage 70 along the suggestedcut line 79 with a knife. In another embodiment, the machine user cuts thepackage 70 along the suggestedcut line 79 with cutting shears, or any other cutting tool sufficient to divide thepackage 70 along the suggestedcut line 79. - In this embodiment as further shown in
FIG. 4 , thepackage 70 incorporating theslit 76 is delivered to the machine user without a protective covering over theslit 76. Alternatively, thepackage 70 may include aprotective covering 81 to protect thebody 72 of blowing insulation from dirt, water and other foreign contaminants during the period of time in which thepackage 70 is in storage or delivery. Theprotective covering 81 could be a see-through film, or any other covering sufficient to protect thepackage 70 from foreign contamination. - In one embodiment as shown in
FIG. 4 , thepackage 70 includes a plurality ofimages 78 disposed on thebag 74. Theimages 78 are disposed on thebag 74 by various methods including printing on the bag or by stickers disposed on thebag 74 or by any other method sufficient to dispose images on thebag 74. Theimages 78 include instructions to the machine user for cutting thepackage 70 along the suggestedcut line 79, or cutting thepackage 70 in anotherpackage 70 location. In another embodiment, theimages 78 include instructions informing the machine user on feeding the half-packages 71 into themachine 10. In yet another embodiment, theimages 78 include instructions to the machine user for disposal of thebag 74 after thebody 72 of blowing insulation has been fed into thechute 14. In another embodiment, the plurality ofimages 78 include safety messages or warnings to the machine user. - As previously discussed and as shown in
FIG. 3 , thechute 14 has a substantially rectangular cross-sectional shape that approximates the substantially cross-sectional shape of thepackage 70. In another embodiment, thechute 14 may have a round cross-sectional shape that approximates the cross-sectional shape of apackage 70 a of blowing insulation in roll form, as shown inFIG. 6 . In this embodiment, theslit 76 extends into thepackage 70 a to extent of one-half of the diameter of thepackage 70 a and is disposed to be substantially perpendicular to the length of thepackage 70 a as defined by slit plane P. As discussed previously, theslit 76 enables the machine user to readily cut thepackage 70 a along the suggestedcut line 79 thereby forming half packages. - In general operation, packages 70 of compressed blowing insulation are provided to the machine user. The
packages 70 include aslit 76 which partially divides the package into pre-cut and un-cut portions.Images 78 provided on thepackage 70 to instruct the machine user on the location of the final cutting of thepackage 70 and optionally, theimages 78 provide a suggestedcut line 79. The machine user cuts the un-cut portion of thepackage 70 along the optional suggested cutline 79 which divides thepackage 70 into approximate half packages 71. Eachhalf package 71 includes abag end 75 and anopen end 77 as shown inFIG. 5 . The machine user grips thebag end 75 of thehalf package 71 and feeds theopen end 77 of thehalf package 71 into thechute 14 of the blowinginsulation machine 10. The machine user continues gripping thebag end 75 as the blowinginsulation 72 is fed into thechute 14. After the blowinginsulation 72 has been fed into thechute 14, the machine user withdraws theempty bag 74 from themachine 10. - In another embodiment as shown in
FIG. 7 , thebody 172 of blowing insulation is encapsulated in asleeve 182 to form aninsulation pack 184. Thesleeve 182 is made of a polymeric material, such as polyethylene, although any type of material suitable for maintaining the blowing insulation in the desired compression can be used. While thesleeve 182 shown inFIG. 7 is a one piece member, thesleeve 182 is defined to be any material or structure, such as bands, film or glue, sufficient to maintain thebody 172 of blowing insulation in the desired compression. - An optional
gripping tab 186 is connected to thesleeve 182 and extends past the end of thesleeve 182. Thegripping tab 186 is gripped by the machine user as theinsulation pack 184 is fed into thechute 14 and allows the machine user to easily retain thesleeve 182 after the blowing insulation has been fed into themachine 10. While a singlegripping tab 186 is shown inFIG. 7 , it should be understood that more than one grippingtab 186 may be connected to thesleeve 182. Thegripping tab 186 can be any material, such as plastic, sufficient to be gripped by the machine user and retain thesleeve 182 as theinsulation pack 184 is fed into themachine 10. - As shown in
FIG. 8 , at least two insulation packs 184 can be assembled together end-to-end. The end-to-end insulation packs 184 are encapsulated with abag 174 to form apackage 170. As discussed previously, thebag 174 can be any material, such as a polymeric material, suitable to provide a waterproof barrier against water, dirt and other deleterious effects. By using a polymeric material for thebag 174, the compressed blowing insulation will be protected from the elements during transportation and storage of thepackage 170. As shown inFIG. 8 , the insulation packs 184 can be assembled together end-to-end and encapsulated by thebag 174. In another embodiment, the insulation packs 184 can be stacked as shown inFIG. 9 and encapsulated by thebag 174 or assembled together in any other manner to provide aconvenient package 170. - In one embodiment as shown in
FIG. 8 , thepackage 170 can include a plurality ofimages 178 disposed on thebag 174. Theimages 178 can be disposed on thebag 74 in a manner similar to that previously discussed. Theimages 178 can include suggested cutlines 179 and instructions to the machine user for opening thepackage 170 or instructions for loading the insulation packs 184 into themachine 10. - In general operation of this embodiment, packages 170 are provided to the machine user. The
packages 170 includeimages 178 provided on thepackage 170 instructing the machine user on opening of thepackage 170. Optionally, theimages 178 provide a suggestedcut line 179 for opening thepackage 170. As an additional option, thepackage 170 may includeperforations 188 enabling the machine user to readily open thepackage 170. The machine user opens thepackage 170 at the prescribed opening locations by cutting thepackage 170 or by the opening method provided by theimages 178.
