Frangible fiberglass insulation batts

A method of producing a frangible fiberglass insulation batt, the method comprising the acts of

• moving a fiberglass insulation blanket in a conveyance direction,
• providing a fluid-reservoir tray supported in an elevated position above the conveyor and formed to include a fluid-discharge aperture opening toward the conveyor,
• aiming a flow of high-pressure fluid discharged from a fluid discharger to pass through the fluid-discharge opening formed in the fluid-reservoir tray and toward the fiberglass insulation blanket, and
• oscillating a fluid blocker for movement in a space located between the fluid discharger and the fluid-reservoir tray relative to the flow of high-pressure fluid through a movement cycle comprising, in series, a first position interrupting the flow of high-pressure fluid, a second position allowing the flow of high-pressure fluid to intercept and penetrate the moving fiberglass insulation blanket to establish a first gap in a series of intermittent gaps, the first position, and a third position allowing the flow of high-pressure fluid to intercept and penetrate the moving fiberglass insulation blanket to establish a second gap in the series of intermittent gaps.

A method of producing a frangible fiberglass insulation batt, the method comprising the acts of

• passing a fiberglass insulation blanket through an interval cutter to cut the fiberglass insulation blanket along a cut line to form two side-by-side strips separated by a series of intermittent gaps to form a frangible plane extending along the cut line, wherein the act of passing comprises the acts of discharging a flow of high-pressure fluid to intercept and penetrate the fiberglass insulation blanket along the cut line to form a gap in the fiberglass insulation blanket as the fiberglass insulation blanket is passed through the interval cutter, interrupting the flow of high-pressure fluid intermittently as the fiberglass insulation blanket is passed through the interval cutter to divert the flow of high-pressure fluid from intercepting and penetrating the fiberglass insulation blank intermittently to establish the series of intermittent gaps in the fiberglass insulation blanket, and moving the fiberglass insulation blanket in a conveyance direction relative to the interval cutter, and wherein the act of interrupting includes the acts of moving a fluid blocker relative to the fiberglass insulation blanket to intercept the flow of high-pressure fluid discharged toward the fiberglass insulation blanket to block the flow of high-pressure fluid from intercepting the fiberglass insulation blanket and oscillating the fluid blocker along a path relative to the fiberglass insulation blanket between a first position placing a blocking surface included in the fluid blocker in a location between an outlet discharging the flow of high-pressure fluid and the fiberglass insulation blanket to cause the flow of high-pressure fluid to impinge upon the blocking surface and a second position allowing the flow of high-pressure fluid to pass through a slot formed in the fluid blocker to intercept and penetrate the fiberglass insulation blanket to establish a first in the series of intermittent gaps.
