ABSTRACT:
A method of integrating organic fibers with mineral fibers includes centrifuging organic fibers from molten organic material, using a rotating organic fiber spinner, directing the organic fibers into a downwardly moving veil of organic fibers and gases, with the veil having an inwardly converging shape as it moves downward, centrifuging mineral fibers from molten mineral material using a rotary mineral fiber spinner positioned concentrically within the downwardly moving veil of organic fibers, directing the mineral fibers into a downwardly moving veil of mineral fibers and gases within the veil of organic fibers, wherein the veil of mineral fibers intersects with the veil of organic fibers to integrate the mineral fibers with the organic fibers, and collecting the integrated mineral fibers and organic fibers as a fibrous pack. An apparatus for performing the method is also disclosed.
