摘要： The present invention concerns an apparatus for ultrasonic processing of materials having an ultrasonic processing system comprising an ultrasound generator, a converter, a sonotrode and a counterpart tool and a feed unit with which the sonotrode and the counterpart tool can be moved towards each other or away from each other, wherein there is provided a force sensor with which the force that the ultrasonic processing system exerts on the materials to be processed can be measured. To provide a corresponding ultrasonic processing apparatus which allows a greater processing speed it is proposed according to the invention that the force sensor is a piezoelectric sensor whose output is converted into an electrical voltage by means of a charge amplifier and that there is provided a control device which either when the ultrasonic processing is not performing material processing short-circuits the piezoelectric sensor or adds a time-varying force compensation unit to the value measured by the piezoelectric sensor.

摘要： The present invention concerns A sonotrode with a wheel-shaped portion having a wheel axis and of a diameter d, which has two substantially circular main surfaces and a substantially cylindrical sealing surface of the width b, that connects the main surfaces. To provide a corresponding sonotrode in which the triangular frequency differs markedly from the main frequency it is proposed according to the invention that at least one main surface has a non-central thickened portion which in a sectional view perpendicularly to the main surface has a convex region which is not arranged on the wheel axis.

摘要： The present invention concerns an apparatus for ultrasonic processing of a material web having an ultrasonic vibration unit which has a sonotrode and a converter connected thereto optionally by way of an amplitude transformer, and a counterpart tool, wherein for processing of the material web the web is moved through a gap between the sonotrode and the counterpart tool, wherein the ultrasonic vibration unit is fixed to a carriage moveable relative to the counterpart tool so that the ultrasonic vibration unit can be moved together with the carriage in the force direction, that is to say in the direction of or away from the counterpart tool, wherein there is provided a force sensor for measuring the force applied to the sonotrode by the material web. To provide a corresponding apparatus of the kind set forth in the opening part of this specification, which permits more accurate measurement of the welding force, in order to be able to continuously process by means of ultrasound even situations of use with an extremely small process bandwidth, it is proposed according to the invention that the sonotrode and the carriage are connected together by way of a sensor component which has the force sensor.

摘要： The present invention concerns a processing element for processing a material, like for example a sonotrode or an anvil, comprising a carrier surface which is substantially in the form of a cylinder or in the form of a segment of a cylinder and which is intended to come into contact with the material during processing, wherein the processing element is intended to be rotated about its longitudinal axis during processing so that the carrier surface rolls on the material to be processed, wherein arranged on the carrier surface is at least one structure element which projects beyond the carrier surface in the radial direction, wherein the structure element has a top side which is provided to come into contact with the material to be processed. To provide a processing element which reduces the abrupt deflection of the sonotrode when the material comes into engagement with and/or comes out of engagement with the carrier surface it is proposed according to the invention that the top side is at least portion-wise convexly curved in the peripheral direction with a radius of curvature which is less than the greatest spacing of the top side from the cylinder axis or comprises at least two surface portions which include an angle
