Abstract
A combination of a sonotrode and anvil, includes a sonotrode/anvil surface and a first row of sonotrode/anvil welding contact elements. The first/second series of each of the sonotrode/anvil welding contact element of a first row includes a first/second adapted lateral surface that joins at least one part of the first/second plateau surface with at least one part of the sonotrode/anvil surface side. The first/second adapted lateral surface includes a first/second curved surface positioned between the first/second plateau surface and the first/second substantially straight surface. The first/second curved surface has a convex outward arch. The welding contact element is positioned in relation to the anvil welding contact element such that the sonotrode welding contact element is positioned during welding next to the anvil welding contact element and is provided to form at least one part of a weld seam.
