Claims4
Apparatus for severing a strand comprising:
- a cutting head linearly movable along an axis, the cutting head having a base section and a conical section, the base section having a cutting edge along the periphery thereof,
- motive means for moving the cutting head between an extended position and a retracted position;
- a die having a bore adapted to slidably receive the cutting head, the bore of the die having a cutting edge at the periphery thereof to cooperate with the cutting edge of the base section of the head to sever the strand as the cutting head moves from the extended position to the retracted position within the casing, the conical section of the head being adapted to permit the strand to slide transversely over the cutting head into a region intermediate the head and die as the head is moved from the retracted position to the extended position.
