A package of fibrous insulation includes a plurality of resilient fibrous insulation blanket layers in a compressed state. The resilient fibrous insulation blanket layers are enveloped within a multi-section covering with different covering sections having at least some information thereon relating to the resilient fibrous insulation layers within the package that is different from the information on another covering section. The covering sections are held in place with respect to each other at least in part by forces exerted on the covering sections by the compressed resilient fibrous insulation blanket layers within the package.

Insulation package

An easy-opening insulation package for containing a stack of resilient insulation batts, such as but not limited to glass fiber insulation batts, is formed from a sheet material. The sheet material completely encircles the batts and has a stress riser that extends longitudinally with respect to the batts for the length of the batts. Preferably, the sheet material has at least one tear line, such as a perforated line, extending generally perpendicular to and crossing the stress riser for creating an opening in the package through the rupture of the sheet material by hand along the perforated line and for permitting the stress riser to be separated by hand from the opening created along the perforated line to gain access to the batts within the package. Preferably, the ends of the package are closed and the perforated line completely encircles the package to permit the package to be separated into two sections by rupturing the perforated line along its entire length.

A unitized package contains a stack of insulation containing packages. The unitized package is formed by a sheet of stretch wrap film that is spirally wrapped about the sides and at least partially overlays the upper and lower surfaces of the stack of insulation containing packages to hold the stack of packages together as a packaged unit. The unitized package has a band adjacent the base of the unitized package which forms a loop adjacent one side of the unitized package to which a pulling means can be secured to pull the unitized package over a horizontal surface, such as a warehouse floor or truck cargo bed, to facilitate moving the unitized package or unloading the unitized package from the truck.

A portable batt cutter custom cuts standard width, continuous, extended length fibrous insulation blankets at a construction site to form batts with specific dimensions corresponding to the dimensions of the structural framework cavities to be insulated. The portable batt cutter includes storage for retaining a fibrous insulation blanket; a feed mechanism for feeding the fibrous insulation blanket from the storage to a transverse cutter; and the transverse cutter which makes a transverse cut across the width of the fibrous insulation blanket to determine the length of the batt. The portable batt cutter may also include a cutter for making a longitudinal cut in the fibrous insulation blanket to form a batt having a width less than the width of the fibrous insulation blanket and a measuring device to measure the length of the batt prior to forming the transverse cut in the fibrous insulation blanket. The portable batt cutter has a size and weight enabling the cutter to be readily moved from construction site to construction site.

A fibrous insulation blanket is pre-cut for custom fitting the insulation blanket into structural framework building cavities of different widths. The width of the blanket is substantially equal to the width of a standard cavity to be insulated by the blanket and the blanket has one or more longitudinally extending cuts in a first major surface of the blanket. The cut(s) have a depth greater than one half of the thickness of the blanket and less than the thickness of the blanket whereby the blanket can be handled as a unit for insulating a cavity having a standard cavity width or easily torn apart at a cut by hand for insulating a cavity having less than a standard cavity width. The second major surface of the blanket may have a facing bonded thereto with one or more perforated lines in the facing aligned with the cut(s) to facilitate tearing apart the blanket by hand if required. Preferably, the perforations of the perforated line(s) are closed by the bonding agent bonding the facing to the blanket so that the facing functions as a vapor barrier in spite of the perforations.

A method and apparatus for forming spiral wound rolls from strips of compressible material uses a first endless belt conveyor to deliver the strips of compressible material into a winding space. As the strip enters the winding space, the strip is compressed by a compression and slider plate to the desired thickness for the layers of strip material in the spiral roll. Then, the leading portion of the strip successively contacts: an inclined, second endless belt conveyor, a compression roll, and a third endless belt conveyor which together with the first conveyor define the winding space. The second conveyor extends upwardly at an acute angle to the first conveyor and as the strip of compressible material contacts the second conveyor it maintains the strip in compression and starts to turn the strip back upon itself to form the spiral roll. The strip next contacts the compression roll which is located intermediate the first and second conveyors. The compression roll continues to turn the strip back upon itself and maintains the strip in compression. The strip next contacts the third conveyor which is located intermediate to the compression roll and the first conveyor. The third conveyor maintains the strip in compression and guides leading portions of the strip inside trailing portions of the strip being fed into the winding space by the first conveyor to complete the spiral winding of each layer of the strip in the roll. The compression roll and the third conveyor and compression and slider plate are moved to enlarge the winding space as the diameter of the spiral roll increases during the winding operation.
