The SONOTRONIC roll seam module, supported at both ends, is used for continuous welding and for Cut&Seal in textile processing, in various industrial sectors. It can easily be incorporated in existing and new machine concepts and is made up of three components: the roll seam sonotrode module (with roll seam sonotrode supported at both ends), the anvil module (exchange anvil) and the control module.

Advantages:
- 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

In the textile industry ultrasonic roll seam units replace conventional sewing machines. Continuous sealing seams and seams with free geometries can be produced. Fabrics from thermoplastic synthetic fibres are then no longer sewn with one thread but are sealed ultrasonically, and because of this no holes are made in the fabric by needle stitches and there is no subsequent taping.
