Abstract
A machine for distributing insulation from a bag of insulation having a cross-sectional shape is provided. The machine includes a chute having an inlet end and an outlet end. The inlet end is oriented in a substantially vertical plane and is configured to receive the bag of insulation. The inlet end has opposing longitudinal sides configured to be substantially horizontal in orientation. The inlet end also has opposing lateral sides connected to the longitudinal sides. The opposing lateral sides are configured to be shorter than the opposing longitudinal sides and further configured to be substantially vertical in orientation. A plurality of shredders is mounted at the outlet end of the chute and is configured to shred and pick apart the insulation. A discharge mechanism is provided for distributing the insulation into an airstream. The chute has a cross-sectional shape that approximates the cross-sectional shape of the bag of insulation.
