It is amazing to see what ultrasonic energy can achieve in joining, cutting, patterning, and quilting on synthetic fabrics. These and more operations are done without the use of thread or adhesives and at speeds much greater than can be reached with sewing machines - as much as four times the speed!
How does it work? As the fabric passes under the machine's horn, ultrasonic vibration causes the materials to heat up and fuse together. Without any additional glue or heat, the seam is finished. When used with cutting edge tooling, the vibration cuts through the fabric and seals the edges of the cut to eliminate any fraying at the edges.
Sewing machine operators quickly adjust to this threadless sewing technique. Modular systems are available for integration into automated textile manufacturing equipment and web handling equipment.
Plunge welding or cutting is accomplished by placing the material over a fixed anvil and having the horn or tool descend to the fabric. This approach is used to punch holes, such as buttonholes, to cut fabric strips to preset lengths, or to join pieces together.
Ultrasonics is a clean and efficient method of joining or slitting synthetic materials.While the initial investment is much more, the long term benefits more than pay for itself.
Ultrasonic bonding uses high frequency sound to generate localized heat through vibration and causes thermoplastic fibers to bond together. Suppliers in the industry say the technology offers several advantages.
A rotary ultrasonic assembly mounted in a bearing housing that can be mounted in any orientation. It is available in 20, 35 kHz with bond widths of up to15MM. The bonder is intended for machinery manufacturers and experienced end users who desire to develop their own actuation and tooling solutions. Ultrasonic Sewing Machines operate like a traditional rotary sewing machine but produce soft, smooth seams that are impervious to moisture or fluids.
Rps-sonic supply high power rotary ultrasonic systems to the packaging, hygiene and specialty converting industries.
Within the hygiene industry, Ultrasonic is used for adult and baby diapers/pant, surgical wrap, and medical face mask products for bonding, attachment, embossing and lamination of thermoplastic materials. The company has engineered solutions for feature attachment, core bonding, acquisition layers and backsheets.
Rps-sonic is also capable and willing to develop comprehensive and customized ultrasonic processing solutions that consider key parameters such as horn metallurgy, acoustic designs and geometries, component fabrication and system engineering in order to meet the processing needs of the customer.
Advantage:
Instead of needles, thread, glues or other adhesives, ultrasonic sewing equipment uses a patented rotary system, coupled with high-frequency vibrations, to bond synthetic or blended materials containing up to 40 percent natural fibers.
Resembling a traditional sewing machine, the ultrasonic sewing machine channels the ultrasonic vibrations between a horn and rotating wheel, producing a localized heat buildup which causes the synthetic fibers to soften and fuse. This creates a strong molecular bond that's impervious to moisture. Explains Alleman, "the resulting barrier seams are sealed, secure, ultra-reliable and soft-to-the-touch without the safety issues caused by stitch holes, glue gaps, fraying or unraveling."
