Abstract
The invention relates to an apparatus and a method for cambering the edge of webs of thermoplastic materials on one or both sides wherein the edges of the web are continuously guided through stamping units and the edges are provided with stampings. The thermoplastic cambering is made by utilizing the energy of ultrasonic vibration. The stamping unit consists of a stamping wheel with pressure apparatus for the wheel and a stationary ultrasonic head arranged beneath it with a sonotrode. A calibration apparatus can be arranged downstream of the stamping unit.
