For your needs in ultrasonic cutting and welding machines, either for the medical and personal protective industries or for the lingerie, please have a look at our standard welding and cutting machines.
Welding
Ultrasonic static welding
How to assemble without, any thread, or needle or glue or any added fabric, thermofusible materials and get an excellent resistance.
Winding and Ejection
Axial winding on core
Welding
Ultrasonic rotary welding
Thanks to the rotary process (wheel and horn are both rotating on parallel axis) the welding process is continuous at speeds from 0 to 350 m / min, depending on the applications.
Unwinding
Axial and/or tangential
Cutting
Continuous ultrasonic cutting
The ultrasonic cutting can be either a single cut to avoid any threading or a cut combined to a welding wheel to reinforce th cutting edge.
Winding and Ejection
Multiple winding
Simultaneous winding of different width cut products
(ex. from 3 to 100 mm on the same axis)
Manufacture and Integration
Automation
Programming from Siemens, Rockwell, Schneider Electric, Omron...
Welding
Ultrasonic welding on drum
A rotary welding drum with the welding pattern on combined to fix horns on a maxi width of 800 mm.
Transfer and Guiding
Transfer and manipulation
Angular rotation at a speed up to 50 m / min of “Light” products such as surgical masks, to re-orientate the product.
Know-how
Threading
Automatic threading of woven fabrics through a ring.
Unwinding
Wide width
Controlled unwinding tension
Width up to 3.20 m
Unwinding speed up to 100 m / min.
Know-how
Hot thermo moulding
A male and a female mould.
Technical or foam fabric moulding for any application even medical.
Welding
Heat cutting / welding and Impulse welding
Heat cutting / welding through blade or heating resistance.
Impulse welding through shaped heating blade.
Winding and Ejection
Horizontal pre-conditioning
Horizontal piling up of folded woven and non-woven products.
Cutting
Continuous mechanical rotary cutting
The continuous mechanical rotary cutting to get a straight cut at high speeds while the fabric is in movement (scissors cutting).
Transfer and Guiding
Transfer - Piling up
Belt transfer and piling up through pushing process.
Folding
Single folding
Folding frame with tension and positioning control.
Manufacture and Integration
Camera Control
Quality control through cameras and control PC for data collection :
- Positioning control
- Dimension control
- Defect control
Winding and Ejection
Vertical pre-conditioning
Vertical piling up of woven or non-woven products.
Welding
Cold sealing
Sealing through wheel and counter wheel.
Transfer and Guiding
Guiding frame
Web recentring all along the process.
Know-how
Samples / Tests
In our test lab, your products are tested and trials are made with the different ultrasonic powers to make sure we can answer your requests.
Folding
Multiple folding
Making of one or several folds in continuous from narrow or wide width.
Unwinding
Multi rolls
Simultaneous unwinding up to 6 rolls.
Control of the roll end with or without automatic splicing.
Manufacture and Integration
Mechanics
For more than 30 years our technicians have been assembling machines, and our specific unit manufactures the mechanical parts as per our specific needs...
Cutting
Mechanical cutting on drum
Rotary blade / counter blade to cut in shape during a continuous process.
