    摘要： The present invention concerns an ultrasonic welding installation comprising an ultrasonic vibration unit having a sonotrode and a converter, wherein the sonotrode and the converter are arranged in mutually adjacent relationship along a longitudinal axis and the ultrasonic vibration unit can be caused to resonate with an ultrasonic vibration in the direction of the longitudinal axis with a wavelength λ/2, wherein there is provided a holder for holding the ultrasonic vibration unit. To provide an ultrasonic welding installation which allows simple and quick highly precise adjustment of the sealing surfaces of the sonotrode relative to the anvil it is proposed according to the invention that the holder has an angle positioning device, wherein the angle positioning device and the ultrasonic vibration unit are of such a configuration that they can be connected together in positively locking relationship so that a rotation of the ultrasonic vibration unit about the longitudinal axis is prevented by the positively locking connection and a relative movement between the ultrasonic vibration unit and the holder in the direction of the longitudinal axis is not prevented.

    摘要： A closed-loop ultrasonic welding apparatus for sealing or welding thermoplastic material on a continuous basis wherein the material to be welded is fed through a weld station comprising a horn and anvil. The apparatus includes means for providing a first signal commensurate with a desired ultrasonic energy density in the material when welded, a second signal responsive to the feed speed of the material through the weld station, and a third signal commensurate with the power coupled by a power supply via a transducer and the horn to the material at the weld station. Control means receive the first, second and third signals and produce an error signal, which is responsive to the difference between the desired energy density and the actual energy density coupled to the material. After being subjected to further processing the error signal is converted to a control signal for controlling the output from said power supply and/or controlling the engagement force between the horn and material. Hence, the welding apparatus causes a predetermined energy density in the welded material irrespective of disturbances or changes in feed speed, engagement force between the horn and material, or the material itself.
