Abstract
A continuous length of material of non-circular cross-section is pelletized to form discrete bits, by feeding the material to a cutting wheel with shaped cutters that form non-planar bits having non-circular axial projections and that are aligned with the material. The material is fed so as to maintain a rotational orientation with respect to the cutters, and so as to avoid buckling. Multiple banks of strands of material are severed simultaneously, thereby producing high volumes of shaped bits that are useful as filling and as filter material, and as friction-enhancing additives.
