Abstract
A method and apparatus for conditioning loose-fill insulation including an elongated tubular cylinder having a plurality of internal blades positioned in a helical configuration. Large nodules of glass fibrous material pass through the conditioning cylinder and are combed into smaller, more uniform sizes, thus allowing a more uniform additive application further downstream in the manufacturing process. The addition of a tangential airflow to the conditioning cylinder facilitates the combing process by adding a tangential force to move the nodules down the cylinder.
