  • Machine and method to feed filled bags, open the bags, empty the bags, and dispose of the empty bags
    Patent number: 7341416
    Abstract: A filled plastic bag may contain insulation. The bags are stacked in a loader. A pair of reciprocating arms rotate a bottom-most bag causing that bag to fall through an opening of a base. A conveyor receives the bag and moves it through a transverse knife and a longitudinal knife. Once the bottom of the bag is slit into quadrants, a pair of gripper wheels peel the bag off. The bag's contents fall into a hopper of a blower.
