摘要： A process for introducing additive particles to extruded fibers during production of the fibers. Particles are directed into a moving stream of fibers during or after the fiber attenuation process. The movement of the fibers intermingles the particles with the fibers prior to the intermingled material being collected on a moving support. If liquid binder is sprayed onto the fibers it is subsequently set in an oven to bind the fibers and the particles to each other. The fibers preferably are mineral fibers and the particles may be fibers or particles introduced for a variety of reasons, such as to increase the strength of the product or to serve as extenders or fillers.
