Abstract
A method of forming an integrated pack of organic and mineral fibers includes centrifuging mineral fibers from molten mineral material using a mineral fiber spinner, directing the mineral fibers into a downwardly moving veil, generating an array of aligned organic fibers from a die and directing the organic fibers into contact with the mineral fibers to integrate the organic fibers with the mineral fibers, and collecting the integrated mineral fibers and organic fibers as a fibrous pack.
