Abstract: Method of continuously molding articles from a fibrous material containing a hardenable bonding material wherein a quantity of fibrous material is supplied to a forming member that engages the surface of the fibrous material and shapes the material into the desired cross-sectional shape. The exterior surface of the shaped fibrous material is then heated so that the bonding material on the exterior surface of the fibrous material cures to form a hard, tough skin on the exterior surface of the fibrous material. Then, additional heat is supplied to the fibrous material to cure the remaining uncured bonding material on the fibrous material so the fibrous material will be held in the desired shape by the cured bonding material.

Abstract: A method of moldng a product which involves delivering a supported body or mass of material that may be molded such as mineral fibers impregnated with a binder into a contoured molding facility, the body or mass of material being compressed and shaped to the mold contour, the binder set or cured and the molded product removed from the mold concomitantly with the advance of a succeeding supported mass or body of moldable mineral into the molding facility.
