RPS-R35
RPS-SONIC
8452219000
Ordinary Ultrasonic Lace Sewing Machine
Flat straight block horn, single-side vibration surface only
Vertical straight transducer assembly, simple vertical force transmission
Only one narrow strip of vibration contact surface, narrow effective welding width
Embossing roller bears all pressure, easy to slip when processing thick multi-layer fabrics
Annular cylindrical radial horn, full circumferential vibration surface
Special rotary radial transducer, optimized vibration balance structure
Wider effective welding width (max up to 10–12mm)
Uniform circumferential pressure distribution, stable feeding without fabric deviation
Suitable for thin single-layer fabrics: lace, satin ribbon, thin non-woven, decorative small ornaments
Only thin linear seam, limited tensile strength on thick materials
Easy to produce uneven fusion, partial weak welding on multi-layer thick cloth
Main functions: thin fabric embossing, lace trimming, simple edge sealing
Compatible with thick multi-layer fabrics, heavy webbing, elastic bands, thick filter cloth, medical protective gown, luggage straps
360° uniform energy creates high-strength full-width fusion seam, stronger pull resistance
Even fusion for high-density, high-viscosity composite textiles, no partial cold welding
Multi-function: long-distance continuous sewing, thick tape welding, curve stitching, wide-width sealing, intermittent wave cutting
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.
