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.

A method for cutting a sheet of fabric made up at least in part of thermoplastic fibers, said method comprising the steps of: providing a sheet of fabric to be cut which sheet is made up at least in part of thermoplastic fibers, providing a cutting blade for cutting said sheet, plunging a tip of said cutting blade through said sheet and reciprocating said cutting blade relative to a heating element, a heating field of said heating element and said sheet to cause it to cut said sheet, actively heating said cutting blade by said heating element while reciprocating the blade, sensing the temperature of said cutting blade, and controlling the heating of said cutting blade in response to the sensing of the temperature of said cutting blade to maintain the temperature at a pre-determined level, the step of sensing the temperature of said cutting blade being performed by using an infrared sensor.
