Descripersion
Flexible technology for a flexible market
Today’s textile and nonwoven market is so complex that fields of application, production techniques and technologies for further processing as well as the variety of new products are difficult to grasp, even for specialists.The variety of new composite materials of fleece, paper, films and fabric as well as the numerous possibilities in terms of combinations have one requirement in common: a safe and reliable process.
Ultrasonics is also the method of choice for these materials, for example for parting fabrics so that there is no thickening of the material along the cut edges.
No consumables such as glue, staples or sewing thread are needed. The fabric remains intact, because no external thermal energy is directed into the fleece. Position, shape and displacement of the welding points can even support the desired properties of the composite.
Textiles is thus a field where ultrasonic technology can prove its uniqueness.
Characteristics:
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.

Application
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.
- Continuous welding or cutting and sealing (Cut&Seal) of
- Elastic and non-elastic textile materials
- PA, PES, PP, cotton, aramid, dyneema®, glass silk, non-woven and other materials as well as mixed fabrics
- Films
- Possibility to integrate the ultrasonic roll seam welding units in
- Special machines
- Hand-work places
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.”
Pinpoint assembly and welding
Impeccable cleanliness
- The application force can be adjusted by electro-pneumatic pressure control valve
- Circumferential speed of the sonotrode and anvil unit is regulated by a master-slave coupling
- Fan-cooled roll seam sonotrode and ultrasonic converter
No sticky products means optimal hygiene
Highly resistant, even with humid product
