Abstract
An apparatus and method for automatically cutting piled or fleecy fabric sheets including thermoplastic fibers uses a heated cutting instrument to inhibit the generation of dust during the cutting process. The heated cutting instrument heats and melts at least some portion of at least some of the thermoplastic fibers which contact or near it, the melted material in turn capturing and holding to the sheets free cut fiber portions which might otherwise fall from the sheets to create dust. An induction coil or an electrical resistance heating material may be used to heat the cutting instrument, and a cooling means may also be used to aid in maintaining a desired cutting instrument temperature.
