Abstract
A machine for distributing blowing wool from a bag of compressed blowing wool is provided. The machine includes a shredding chamber having an outlet end. The shredding chamber includes a plurality of shredders configured to shred and pick apart the blowing wool. A discharge mechanism is mounted at the outlet end of the shredding chamber and is configured for distributing the blowing wool into an airstream. The discharge mechanism includes a housing and a plurality of sealing vane assemblies mounted for rotation. The housing has a wrap angle of approximately 240°. The sealing vane assemblies are configured to seal against the housing as the sealing vane assemblies rotate. The housing includes an eccentric segment extending from the housing. A blower is configured to provide the airstream flowing through the discharge mechanism. The sealing vane assemblies become spaced apart from the housing as the sealing vane assemblies rotate through the eccentric segment.
