Patent number: 7066065Abstract: At least one longitudinally extending series of cuts and separable connectors is formed in a fibrous insulation blanket with one or more rotating compression-cutting blades and a cooperating anvil to form separable blanket sections in the insulation blanket. The size and configuration of the teeth and notches in the compression-cutting blade, which may be determined through the use of an empirical equation, insure that the insulation blanket has the integrity to be handled and installed as a unit, but can be separated by hand into the blanket sections. The anvil has a moving surface that drives the compression-cutting blade at the velocity blanket is being fed between the cutting blade and the anvil.Type: GrantFiled: January 10, 2005Date of Patent: June 27, 2006Assignee: Johns ManvilleInventors: Robert J. Allwein, Blake B. Bogrett, Larry J. Weinstein

Patent number: 7041353Abstract: An insulation package contains a plurality of unfaced or faced, uncut and pre-cut fibrous insulation batts of a pre-selected width enveloped within a covering in a compressed condition. Each of the pre-cut fibrous insulation batts has a plurality of longitudinally extending batt sections separably joined to adjacent batt sections by separable connectors. The separable connectors hold the pre-cut fibrous insulation batt together for handling but can be separated along the lengths of the batt sections by hand to separate adjacent batt sections. Preferably, between 20% and 70% of the fibrous insulation batts in each of the insulation packages are pre-cut fibrous insulation batts.Type: GrantFiled: August 31, 2001Date of Patent: May 9, 2006Assignee: Johns ManvilleInventors: John Brooks Smith, Blake Boyd Bogrett, Dennis Robert Larratt, Larry J. Weinstein, Robert J. Allwein

Patent number: 7029739Abstract: An elongated fibrous insulation blanket is pre-cut for custom fitting the insulation blanket into wall, floor, ceiling and roof cavities of different widths formed by the framework of a building. The blanket has at least one, preferably two or three, series of cuts extending between major surfaces of the blanket with successive cuts of each series of cuts being separated by a series of separable connectors located intermediate the major surfaces of the blanket. Each series of separable connectors hold together adjacent sections of the blanket for handling, but are separable by hand so that the blanket can be handled as a unit for insulating a cavity having a predetermined width or easily separated by hand into two or more sections at one or more of the series of separable connectors for insulating a cavity having a lesser width.Type: GrantFiled: December 2, 2003Date of Patent: April 18, 2006Assignee: Johns ManvilleInventors: Larry J. Weinstein, Robert J. Allwein

Patent number: 6935080Abstract: An elongated fibrous insulation blanket is pre-cut for custom fitting the insulation blanket into wall, floor, ceiling and roof cavities of different widths formed by the framework of a building. The blanket has one or more cuts extending for the length of the blanket which separate the blanket into two or more longitudinally extending sections. Adjacent sections of the blanket are joined together along the cut(s) by separable adhesive connectors which hold together the sections of the blanket for handling, but are separable by hand along the cut(s) so that the blanket can be handled as a unit for insulating a cavity having a predetermined width or easily separated by hand into two or more sections at a cut for insulating a cavity having a lesser width. The pre-cut insulation blanket may have a facing sheet, overlaying and bonded to a major surface of the blanket, that is separable by hand along the cut(s).Type: GrantFiled: February 13, 2001Date of Patent: August 30, 2005Assignee: Johns Manville International, Inc.Inventors: Robert J.

Publication number: 20030022580Abstract: Resilient fibrous insulation batts are formed with the fibers of the batts being randomly oriented and entangled together and predominately lying in planes that extend substantially perpendicular to the major surfaces and the end surfaces of the batts and substantially parallel to the lateral surfaces of the batts to facilitate a widthwise compression of the batts. The batts are formed by collecting fibers into a blanket with the fibers being collected in layers lying in planes extending substantially parallel to the major surfaces of the blanket and the blanket having a thickness equal to the widths of the batts to be formed. The blanket is then cut longitudinally and transversely, in directions perpendicular to the major surfaces of the blanket, into sections having thicknesses and lengths equal to those of the batts to complete the formation of the batts.Type: ApplicationFiled: July 24, 2001Publication date: January 30, 2003Inventors: Blake B.

Patent number: 6510945Abstract: 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.Type: GrantFiled: September 17, 1998Date of Patent: January 28, 2003Assignee: Johns Manville International, Inc.Inventors: Robert J.

Patent number: 6383594Abstract: A fibrous insulation blanket is pre-cut for custom fitting the insulation blanket into wall, floor, ceiling and roof cavities of different widths formed by the framework of a building. The insulation blanket has one or more pairs of longitudinally extending cuts in the major surfaces of the blanket. Each pair of cut(s) leaves a separable connector within the blanket between adjacent sections of the insulation blanket whereby the blanket can be handled as a unit for insulating a cavity having a width about equal to the width of the blanket or easily separated or torn apart by hand at a separable connector for insulating a cavity having a lesser width. A major surface of the blanket may have a facing bonded thereto that is separable by hand along the cut(s) in the major surface to facilitate separating the blanket by hand.Type: GrantFiled: June 8, 2001Date of Patent: May 7, 2002Assignee: Johns Manville International, Inc.Inventors: Larry J.
