An apparatus for ultrasonically welding sealing seams on solvent packages is described. The apparatus has a sonotrode and an anvil (7) which is situated opposite the front end face of the sonotrode. Both the sonotrode and the anvil (7) can be moved on predetermined tracks. …<??>So that the bearings of the entire machine are not damaged by the vibrations of the sonotrode, and therefore of the anvil as well, while at the same time guaranteeing good hygienic properties, provision has been made according to the invention for the solidly structured anvil to be axially penetrated by at least one inner bore (12, 13, 14) in which a shaft (9, 10, 11) is arranged in a contact-free manner for decoupling of the vibrations via elastic, flexible ring parts (16) while forming an annular gap, the outside diameter of the said shaft (9, 10, 11) being smaller than the inside diameter of the inner bore (12, 13, 14), and for the outside diameter of the elastic ring part (16) to be larger than the inside diameter of the inner bore. …<IMAGE>… …<IMAGE>… |
