ABSTRACT:
A cutting apparatus for continuous lengths of filaments bundles, film ribbons, filamentary-type or other material in strip like form is disclosed containing a tube that is readily adjustable in very small increments relative to rotating blades. A housing surrounds the exit end of the tube and rotating blades which is attached to a suction device. The device creates a high velocity flow of air through the tube which aligns the filamentary material for cutting. An insert may be placed in the tube which contains an upper surface or anvil at its outer end. The tube and/or the insert in the tube is adjustable in two dimensions relative to one or more blades rotating in a plane transverse to the axis of the tube. These adjustments which may be made during operation of the cutting process to facilitate a cleaner, uniform cutting of the filamentary material.
