Abstract
A cutting roller 2 of a glass filament chopping apparatus mounts a plurality of spaced, axially parallel cutting blades 19 held in receiving grooves 20 by retainer strips 21. The peripheral flange surfaces 24, 25 of the cutting roller on the opposite ends of the roller drum 18 are raised to almost the radius of the cutting blade edges, and serve as driving engagement surfaces when the rotating cutting roller is biased into contact with a feed roller 1.
