摘要：
A method of manufacturing a strap for a headgear system for holding a respiratory mask in position on a face of a patient, the method comprising the steps of laminating at least one layer of material to a fabric layer to form a laminate, thermoforming the laminate, and ultrasonically die cutting the laminate to form the strap. The strap has a patient-contacting side, an opposite non patient-contacting side and two lateral sides. The fabric layer is on the patient-contacting side of the strap, and the ultrasonic die cutting forms a rounded edge between the patient contacting side and at least one of the lateral sides. The rounded edge prevents cutting by the strap
