Abstract
A method and apparatus for cutting continuous funicular material such as tow bands of fibrous material of glass, synthetics, metal, or staple spun threads of any generic type is disclosed wherein two relatively movable closely spaced members are provided with a plurality of knives affixed to the surface of at least one of the members. The material is fed between the rotors and trapped and cut by the knives in a scissors-like manner. In a preferred embodiment, the members are both rotors mounted concentrically each with a plurality of knives. After cutting, the cut staple is flung outwardly from the rotors by centrifugal force.
