Abstract
Abstract A method and apparatus are provided for handling compressible batts of glass fiber insulation. The batts are sequentially removed from a conveyor line and stacked on one another at a loading or stacking station to a predetermined number or height. The stack of batts is moved away from the point of stacking and compressed by a bat compressing and carrying unit, and additional compressible batts are sequentially removed from the conveyor line and stacked at the stacking station. The second stack of batts is then compressed adjacent the first stack by the unit and the two stacks moved together by the unit from the stacking station to a packaging station. Suction is applied to the two stacks of batts at the packaging station while fingers of the batt compressing and carrying unit, which fingers supply the compressive forces on the batts, are moved apart and retracted. The two stacks of batts are then packaged at the second station while additional batts are removed from the line and stacked at the stacking station for the next package.
