Abstract
A method of and apparatus for accelerating a filament wherein an impelling force is applied to a length of filament a torque arm distance from an axis of rotation to rotate the length of filament about the axis of rotation thereby developing a tip speed that is of sufficient velocity for using the tip portion to cut a workpiece and, alternatively, to sequentially release the moving tip portion to discharge a series of particles for performing welding, drilling, coating, cutting and like operations. The length of filament, preferably, is the end section of a coil of filament and is simultaneously advanced along the longitudinal axis of the length of filament toward the tip portion during the application of said impelling forces. The advancement of the filament is controlled. The enclosure of the filament in an evacuated space increases the speed range.
