Abstract
A method for producing mineral fibers includes centrifuging mineral fibers from one or more rotary mineral fiber spinners to establish one or more downwardly moving veils of mineral fibers positioned above a collecting surface, centrifuging organic fibers from molten organic material using one or more rotary organic fiber spinners to establish one or more downwardly moving veils of organic fibers positioned above the collecting surface, the veils of mineral fibers being generally colinear with the veils of organic fibers, the veils of organic fibers alternating with the veils of mineral fibers to integrate the organic material and the mineral fibers, and collecting the integrated organic material and mineral fibers on the collecting surface.
