Title:
APPARATUS AND METHOD FOR CUTTING SHEET-TYPE WORK MATERIAL USING A BLADE RECIPROCATED VIA A TUNED RESONATOR
Document Type and Number:
WIPO Patent Application WO2004011210
Kind Code:
A3
Abstract:
In a resonating assembly (30, 130, 230), a beam (34, 134) having a pickup (36, 136) thereon is positioned proximate to a magnet (46, 146) 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 (48, 148) 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 (16) the vibratory amplitude of the blade causes the blade to cut through the material as it is moved in engagement therewith.
