  • Ultrasonic sewing machine and bonding wheel assembly
    Patent number: 6325127
    Abstract: An ultrasonic seam welding apparatus for seam welding at least two sheetlike work pieces piled one above the other by imparting ultrasonic osculation is expressed through the ultrasonic binding and cutting quill assembly. The ultrasound seaming and cutting apparatus comprises a receptive resonant horn or wheel for receiving a rotating anvil wheel and a cutting surface thereon. An apparatus and receiving component having overlapping surfaces and welding the components together with the use of ultrasound. An ultrasound emitter and wheel receives the high frequency current and converts it into mechanical ultrasonic vibrations having the same frequency.
