Title: Method for cutting fibers

Abstract: A method and apparatus for cutting threads, particularly threads formed of mineral substances such as glass, are disclosed. A rotating drum carrying a plurality of radially extending cutting blades operates in conjunction with a rotating support drum which carries and supports the thread for cutting by the cutting blades. Ejector elements carried by the cutting drum and positioned in the spaces between the cutting blades are urged radially outwardly by centrifugal force and compress the thread against the surface of the support drum. The ejector elements then serve to strip cut sections of the thread from between the blades as the cutting blades move away from the support drum. Compressed air is supplied to the spaces between the cutting blades to remove waste material resulting from the cutting operation.
