Method and apparatus for ultrasonic welding of laminated material such as, for example, paper or cardboard coated with weldable plastic. The materials to be welded to one another are clamped between a sonotrode (2) as ultrasonic transducer and an anvil (1) as abutment. In this process, the ultrasonic waves act on the material at an angle (alpha) to the vertical. Owing to this oblique positioning of the ultrasonic source, in addition to the welding of the layers of material the transport of the latter through the welding device is achieved. The anvil (1) can be configured as a roll with or without drive. <IMAGE> |
