Abstract
A rotary acoustic horn imparts energy at a selected wavelength, frequency, and amplitude. The horn includes a base portion and a plurality of weld faces. Each weld face has a diameter that expands and contracts with the application of ultrasonic energy. The weld faces are spaced from each other and are mounted in one of series and parallel with each other.
Claims11
A rotary acoustic horn for imparting energy at a selected wavelength, frequency, and amplitude, wherein the horn comprises:
- a base portion having an axial input end and an axial output end;
- a plurality of weld faces operationally connected to the base portion, each having a diameter that is greater than the diameter of the base portion and that expands and contracts with the application of acoustic energy to the input end of the base portion, wherein the weld faces are spaced from each other, and wherein the weld faces are mounted in one of series and parallel with each other.
A rotary acoustic horn setup for imparting energy at a selected wavelength, frequency, and amplitude, wherein the setup comprises first and second horns and wherein each horn comprises:
- a base portion having an axial input end and an axial output end;
- a plurality of weld faces operationally connected to the base portion, each having a diameter that is greater than the diameter of the base portion and that expands and contracts with the application of acoustic energy to the input end of the base portion, wherein the weld faces are spaced from each other, and wherein the weld faces are mounted in one of series and parallel with each other;
- wherein the weld faces on the first horn are staggered, with respect to adjacent weld faces on the second horn, by a distance sufficient to cover completely a width of an anvil against which welding occurs.
