  • Patent number: 4658713
    Abstract: A first and a second leading member are disposed in opposite relation with one another and are supported for movement in a direction axially of a cutting apparatus. A first and a second cutter are supported for movement integral with the respective leading members and are disposed in opposite relation with one another and at locations downstreams of the leading members in a direction transversely of the apparatus and closer to the bulb to be cut than the leading member in the direction axially of the apparatus. The leading members move toward one another and the respective cutters are rotatably driven by motors. The leading members are adapted to abut against the bulb, to be displaced away from one another by the bulb so as to cause the cutters to assume their desired positions for a cutting operation.
