<p>A method of making a fibrous pack (36) includes centrifuging at least two sets of mineral fibers from molten material using at least two rotary mineral fiber spinners (12) that are arranged in a machine direction along a collection surface (14), directing each set of the mineral fibers into a downwardly moving veil (24) beneath one of the mineral fiber spinners (12), generating a downwardly moving array (52) of aligned organic fibers from at least one orificed die (50) that is spaced apart from each of the mineral fiber spinners (12) and directing the array (52) into contact with the mineral fibers, and collecting the mineral fibers and organic fibers as a fibrous pack (36).</p> |
