ABSTRACT:
An apparatus for forming shaped surfaces of an elongate substrate is disclosed. The apparatus includes a first and second collar spaced along the substrate, wherein a cutting filament extends between the collars. The collars are selectively rotated to pass the cutting filament through the substrate and form a shaped surface. The shaped surface can include conical or frustoconical shapes.
