ABSTRACT OF THE DISCLOSURE A method and machine for Forming nonwoven batts containing refractory fibers such as carbon, glass, ceramic or metallic fibers, includes a conveying table (12) provided with scalloped rollers (90, 92) which separate tows o-f Filaments (16) and spread the -filaments on a conveying table. A feed roller (80) holds the filaments on the table so that they are conveyed to a rotating lickerin (60). The lickerin (60) is provided with teeth (62) which grasp the filaments so that a tensile force is applied thereto, thereby breaking the filaments at structurally weak points in the Filaments. The fibers are mixed with textile fibers and transferred to a foraminous con- denser (144) by blowing the fibers through a duct (112). The fibers are arranged on the conveyor (114) in a random fashion to form a batt.
