PURPOSE: A sewing machine is provided to manufacture beautiful clothing with no wrinkle on the sewing connected part by ultrasonic dicing and welding without extra needle or sewing thread. CONSTITUTION: A sewing machine comprises the base(10), the pressing part(34), and the heating part(32). The pressing part continuously presses the transferred work piece along the base according to the designed shape. The heating portion provides the friction heat energy to the pressed work piece by the pressing part, and cuts and fuses the work piece. The heating part comprises the ultrasonic generator(32b) and the radiator(32a). The radiator concentrates the ultrasonic supplied from the ultrasonic generator and provides the friction heat energy to the work piece.
