SONOTRODE WITH THICKENED PORTION

摘要

The invention relates to a sonotrode with a wheel-shaped portion with a wheel axis and a diameter d, having two substantially circular main surfaces and a substantially cylindrical sealing surface which connects the main surfaces and has the width b. The aim of the invention is to provide a corresponding sonotrode in which the triangular frequency significantly differs from the main frequency. According to the invention, this is achieved in that at least one main surface has a non-central thickened portion which has a convex region that is not arranged on the wheel axis when seen in a sectional view perpendicular to the main surface.
