Products Top technology in ultrasonic welding

Our NUCLEUS-Rotosonic machines are productive, flexible and easy to operate. Convince yourself of the wide range of applications for our solutions: from manual individual workstations to semi-automatic or fully automatic machine solutions and benefit from our know-how.

Technology The ultrasonic welding process with rotating sonotrode

Welding, i.e. the joining of several textile or natural fibre surfaces, presupposes that certain proportions of thermoplastic, heat-formable materials are present in them. Since most of the technical textiles used today are based on synthetic base materials, these are perfectly suitable for welding.

Advantages Numerous advantages through trend-setting welding technology

With the roll seam method used by NUCLEUS, the weld metal is continuously welded between two discs rolling on each other, so that, as with a sewing machine, continuous seams or even curved seam contours are possible.
