fibrous insulation blanket 34 to the transverse cutting station 26 preferably the pull roll 50 has a length and the belt conveyor 52 has a width equal to or greater than the widest fibrous insulation blanket 34 to be processed on the portable batt cutter 20 the pull roll 50 and preferably a drive roll 54 of the belt conveyor 52 are each powered by a conventional electric motor not shown the underside of the pull roll 50 and the upper surface of the belt conveyor 52 are spaced apart a distance less than the thickness of the fibrous insulation blanket 34 being processed on the portable batt cutter 20 so that the blanket 34 is gripped between the underside of the pull roll 50 and the upper surface of the belt conveyor 52 thus as the pull roll 50 rotates and the belt conveyor 52 moves in the direction shown in fig2 the pull roll and the belt conveyor cooperate to pull the fibrous insulation blanket 34 from the bulk roll 32 or the z folded insulation 132 and feed the fibrous insulation blanket 34 to the transverse cutting station 26 preferably the pull roll 50 and the drive roll 54 of the belt conveyor 52 are mounted so that the spacing between the underside of the pull roll 50 and the upper surface of the belt conveyor 52 can be adjusted e g by raising or lowering the pull roll 50 relative to the drive roll 54 by conventional means not shown to accommodate fibrous insulation blankets 34 of various thicknesses as schematically shown.
