Patent ID: 7341416

Claim:
A system for opening rectangular bags of non-powdered insulation material into a dispensing subsystem, the system comprising: a storage subsystem capable of holding one or more rectangular bags of a same first size in a vertical stack; a releasing subsystem capable of releasing a rectangular bag located at a bottom of the vertical stack (first bag) from the storage subsystem into a first conveyor subsystem; wherein the first conveyor subsystem is capable of transporting the first bag from the storage subsystem to a cutting subsystem; the cutting subsystem comprising a longitudinal stationary blade and a moving transverse blade; wherein the longitudinal stationary blade cuts one or more longitudinal slits in a bottom of the first bag in a longitudinal direction as the first bag travels through the cutting subsystem; wherein the moving transverse blade cuts a plurality of slits in the bottom of the first bag in a transverse direction as the first bag travels through the cutting subsystem; the transverse slits intersecting the longitudinal slits; a gripping subsystem comprising two gripping wheels capable of separating the first bag from the non-powdered insulation material housed within the first bag after the first bag is cut; and wherein the non-powdered insulation material falls from the gripping subsystem into the dispensing subsystem.
