Abstract:

An apparatus and method for applying cellulose fiber insulation of the spray on loose fill type. The insulation is coated by a dry and thus deactivated adhesive and is stored in a storage tank. At the moment it exits the storage tanks, the insulation is exposed to and moistened by water sprayed by a nozzle member. The moistened insulation travels the length of a blow hose to reach the application site at the discharge end of the blow tube. The moisture activates the dry adhesive as the insulation travels through the hose, and the turbulence within the hose ensures that all of the fibers are moistened. Thus, by the time the adhesive is discharged by the blow tube, it sets in the absence of dust and virtually no setting time is required because the activated adhesive has begun to set.
