ABSTRACT:
A process for supplying insulating materials wherein fibrous insulating material moves in a confined turbulent air stream into which an adhesive is injected. Air under pressure is also injected so that portions of the air are entrapped within the fibrous insulating material. The injection of the adhesive and the air increases the pressure of the confined moving air stream so that the fibrous insulating material expands and fluffs when released to the atmosphere.
