PP Spunbond Rotary Ultrasonic sealing equipment Continuous welding

Descripersion

Continuous welding on pp spunbond is asked very often in the market so RPS-SONIC provides a rotary welding system. There are special rollers for this welding method. The roller figures and figure depth depend on the material type and material thickness. Sonikel makes co-operation with fabric manufacturers to find the right solution and invests its R&D Department.Seat belt textile or similar poliester fabrics should be cut smoothly but the problem starts at the cutting point. At the cutting point, very small fabrics can go out from the textile. Ultrasonic cutting method, cuts and seals at the same time so there is no small fabrics at the cutting point. Another method is by heating knife but this time the cutting point becomes very hard, not soft. So when the user touches it, it can damage hand. After Ultrasonic cut and seal process, the edges are soft and there is no short fabrics, all of them are sealed.

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:

Application

• 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.

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.”
