Tool for an ultrasonic welding device and associated method

Abstract

A tool for an ultrasonic sealing device with a base surface, wherein the base surface has a first elevation which extends from the base surface in a direction perpendicular to the base surface, wherein the first elevation has a first partial sealing surface, wherein the first partial sealing surface has a second elevation which extends from the first partial sealing surface in a direction perpendicular to the first partial sealing surface, wherein the second elevation has a second partial sealing surface. In order to provide a tool with which aluminum-free plastic materials, in particular polypropylene sealing layers, can also be reliably sealed, it is proposed according to the invention that both the first partial sealing surface and the second partial sealing surface are provided for processing a material.
