  • Patent number: 4445408
    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.

  • Patent number: 3978751
    Abstract: This patent presents apparatus for cutting staple fibers to predetermined accurate lengths from yarn, tow or ropes. The apparatus includes a circular assembly incorporating a plurality of knives and one or more camming means which cooperate with the plurality of knives to pull a tow into cutting engagement with the knives in response to rotational movement of either the knife assembly or the camming means. A movable endless belt encircles the camming means and is adapted to move with the tow and, thereby, eliminate frictional heating generated between the tow/s and the camming surface/s. In one embodiment the endless belt is supported by a film of air, gas or liquid between it and the cam, and in an alternate embodiment the cam is a circular rotatable means and the endless belt is in direct contact therewith, but frictional heating is effectively eliminated because sliding engagement between the endless belt and the camming means is minimized.
