Abstract (en)

[origin: WO9734845A1] A method for forming an insulation product includes centrifuging irregular glass fibers (116) using a rotary process, collecting the fibers as a pack (48), continuously withdrawing a portion of the fibers (116) from the pack (48) to generate a continuous yarn of fibers (116), and pneumatically propelling the yarn toward a receptacle, such as an insulation cativy, to form an insulation product. Also, a strand of continuous, irregular textile fibers (116) can be payed out from a wound package and pneumatically propelled toward a receptacle, such as an insulation cavity, to form an insulation product.
