  • Apparatus and method for cutting sheet-type work material using a blade reciprocated via a tuned resonator
    Publication number: 20040099107
    Abstract: In a resonating assembly, a beam having a pickup thereon is positioned proximate to a magnet which passes across the pick up at a predetermined frequency. The passage of the magnet across the pick up establishes an alternating magnetic field that in turn causes the beam and pick up to vibrate. A blade is mounted on the beam and vibrates therewith so that when the blade is brought into engagement with a layer of sheet type work material the vibratory amplitude of the blade causes the blade to cut through the material as it is moved in engagement therewith.
