Ultrasonic sewing machine








Viale de Gasperi, 76
20017 RHO (MI) Italia



The ultrasonic sewing process is versatile - you can seam, cut, slit, trim, tack, emboss, or cut and seal simultaneously. The process used by an ultrasonic sewing machine for nonwoven is fast - sealing more than 600 feet per minute! It is simple and efficient, with no needles, threads, or other consumables. And, it is flexible. The equipment may be bench or table mounted, or integrated into your automated line.

More about ultrasonic sewing machine


For the "sewn" products industry, there are many advantages with ultrasonic sealing, including:

  • Fast, economical, strong seals.
  • No consumables such as staples, adhesives, or clips.
  • Consistent results - from start-up to end of run.
  • No warm-up time, costly temperature maintenance, or recovery time for an Ultrasonic Sewing Machine.
  • Single operation cut and seal with no raw edges.
  • Eliminates needles, threads, bobbins, and associated color matching, inventory, winding, and trimming.
  • Noncontaminating, eliminates toxic glue or solvents.
  • Edges are sealed with no stitch holes preventing penetration of chemicals, bloodborne pathogens, and particulates as required by OSHA.


For all its flexibility and versatility, most production carried out by Ultrasonic Sewing Machines is done using two basic modes of operation - plunge or continuous - with variations depending on the application. Sealing and cutting can be done in either mode. In the plunge mode, the ultrasonic horn operates perpendicularly to the material and fuses the layers together in the pattern of the stationary anvil. This technique can be used to simultaneously cut and seal the edges of material. Typical applications using this mode include bra straps and buckles, buttonholes, collar stays, darts, strapping, embossing, grommets, belt loops, filter media (woven and nonwoven), zipper stops, and vertical blinds.


Other advantages of the ultrasonic fabric sewing machine


With the continuous mode, material is moved beneath a stationary horn. Most slitting applications are realized in the continuous mode by an Ultrasonic welding sewing machine.
Ultrasonic slitting produces an edge that is smooth, durable, and clean, with no discoloration of the fabric. Ultrasonics prevents unraveling of knitted or woven materials by sealing the slit edge.
The sealed edge is tapered without a bead that would add unnecessary bulk.
