Zusammenfassung:	A hemming machine has a first station with an ultrasonic slitting device for cutting woven material that has enough thermoplastic content to be cut and fused by an ultrasonic device. At a second station, a hemming device folds and sews the material and by providing only two folds, results in a three layer hem which does not fray because the edge has been fused by the ultrasonic slitting device.
