The first SeamMaster® Ultrasonic Sewing Machine was introduced in October 1991 to meet demands for safer medical garments and disposable items. It has since been awarded trademark registration for its use of high-frequency vibratory waves that produce secure barrier seams and bonded edges without stitch holes, glue gaps, fraying or unraveling.
