ABSTRACT:
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 of 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 condenser (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.
