Patent ID: 6960276

Claim:
A method of producing a frangible fiberglass insulation batt, the method comprising the steps of passing a fiberglass insulation blanket having a major surface defining a width of the fiberglass insulation blanket and a lateral surface defining a thickness of the fiberglass insulation blanket that is less than the width through a cutter to cut the fiberglass insulation blanket along a cut line to produce a cut that extends perpendicular to the major surface of the fiberglass insulation blanket to form two side-by-side separate strips separated by a gap, a first of the strips having a longitudinally extending side edge extending along the cut line, a second of the strips having a longitudinally extending side edge extending along the cut line and opposing the longitudinally extending side edge of the first of the strips to define the gap, applying an adhesive material to at least one of the opposing longitudinally extending side edges, and joining the opposing longitudinally extending side edges together to cause the adhesive material to establish a frangible adhesive bridge spanning the gap between the opposing longitudinally extending side edges and establishing relatively weak internal bonds between the opposing longitudinally extending side edges of the two side-by-side strips to produce a frangible fiberglass insulation batt.
