ROLLER APPARATUS FOR CUTTING GLASS FIBERS

摘要

ABSTRACT OF THE DISCLOSUREThis invention discloses a novel cutting roller forchopping continuous elongated filaments into finite fibers of apredetermined length. A plurality of spaced, axially parallelcutting blades are mounted on a driven roller drum and are heldin receiving groove by retainer strips. The peripheral flangesurface of the cutting roller in the opposite ends of the rollerdrum are raised to almost the radius of the cutting bladeedges and serve as driving engagement surfaces when the rotatingcutting roller is braised into contact with a feed roller. Theproblems of accelerated wear and deterioration of syntheticresin or rubber feed rollers of the prior art and damage to theedges of the cutting blades of the prior art devices have beensuccessfully overcome. Also, the device of the present inventionallows two rollers to revolve at exactly equal circumferentialspeeds which has not been successful with the device of theprior art.
