ABSTRACT:
The description relates to an apparatus for the ultrasonic welding of sealing seams on packages for fluid media. The apparatus comprises a sonotrode and an anvil (7) which is situated opposite the front end face of the sonotrode. Both sonotrode and also anvil (7) are adapted for movement on predetermined paths.
So that the bearings of the machine as a whole are not adversely affected by the vibrations of the sonotrode and thus also of the anvil and in order to guarantee good hygiene qualities, it is according to the invention envisaged that the anvil which is of solid construction should be traversed axially by at least one inner bore (12, 13, 14) in which, for neutralizing vibrations, a shaft (9; 10, 11) is disposed contactlessly via elastic flexible ring parts (16) so that an annular gap is formed, the outside diameter of the shaft being less than the inside diameter of the inner bore (12, 13, 14) and in that the outside diameter of the elastic ring part (16) is greater than the inside diameter of the inner bore.
