Product Description

Ultrasonic Joining systems for web / nonwoven material rotary horn



An ultrasonic rotary horn has tapered input sections for the conversion of axial acoustic energy into radial acoustic energy. The preferred rotary horn includes a first half having a first radial weld section and a first axial input section for receiving a first axial acoustic energy. The rotary horn further includes a second half coupled to the first half. The second half has a second radial weld section and a second axial input section for receiving a second axial acoustic energy. Each half has a coned section defined by an inner tapered surface and an outer tapered surface such that the halves convert a portion of the first and second axial acoustic energy into radial acoustic energy. Each inner tapered surface forms an inner angle with respect to an axis of the horn and each outer tapered surface forms an outer angle with respect to the axis.


An ultrasonic rotary horn comprising: a first radial weld section; and a first axial input section operatively coupled to the first radial weld section for receiving a first axial acoustic energy; said first axial input section having a first hollow coned section including an inner tapered surface forming an inner angle with respect to an axis of the horn and an outer tapered surface forming an outer angle with respect to the axis of the horn, wherein said inner angle is different from said outer angle such that the first axial input section and the first radial weld section convert a portion of the first axial acoustic energy into radial acoustic energy, the radial acoustic energy being in phase with the first axial acoustic energy.



It need be assembled on the ulltrasonic sewing machine, and drive by an other rotary horn.



1. Seamming,trimming and embossing without glue, thread or other consumables
2. More faster and cost effective than traditional sewing machine and adhesive ways
3. Eliminates fraying or unraveling of bonded edges and seams
4. Multifunctional and thousands of designs available
5. Requires minimum training and maintenance
6. Super strong ultrasonic power meets the needs of different fabric thickness


RPS-SONIC specializes in manufacturing ultrasonic seam welding solutions for rotational systems.


Numerous seam soldering devices have been developed over the past years. From sonotrodes that can be installed in automated assembly lines, the Elmrt35 ultrasounds sewing machine up to customizations such as the PFW model devised for continuous welding of pleated filters.


There are two types of rotating modules for these operations: with either a side or central sonotrode resonating at a 35 kHz frequency and power varying from 600W to 1200W.


These horns can be made out of aluminium, treated with a special surface strengthening procedure, or titanium.


Our seam welding solutions are employed in binding synthetic textiles such as PVC, polyester, polypropylene, coated, filtering and technical fabrics.

An ultrasonic sewing machine is versatile and easy to use in order to seam, cut, slit, trim, tack, emboss, or to cut and seal at the same time. The process used by every ultrasonic sewing machine is fast, simple and efficient. It can seal up to 80 meters per minute without the need for threads nor needles.

It is indeed a flexible technology. Due to the adaptability of its design, it is possible to mount the sewing machine on a workbench or to install it into semi or fully automated systems.

Using an ultrasonic sewing machine brings forth a series of advantages:
  • Fast and cost-effective weaving;
  • Resilient seams;
  • No need for consumables such as tape, clips or glue;
  • Fast welding speed, high strength
  • Nice welding seam, good sealing.
  • Low energy consumption and easy operations
  • Constant results;
  • No cooling times and reduced maintenance costs;
  • No shooting time for the stapler tool;
  • Edging in one operation
  • No need for needles, thread, spools and any activities related to color matching, inventories, winding and trimming;
  • Environmentally-friendly because it does not need any adhesives and solvents;
  • Edges get sealed without leaving any stitch holes, thus preventing penetration from chemical agents, bloodborne pathogens and other particles.


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.”
