- Hot melt or by ultrasonic welding. Because of the short welding time and the high strength and process reliability of the welded joint, this is preferably used.
- Directional sensors on the holding plate as well as structuring on the sonotrode or on the anvil further increase the perfor- mance of the ultrasonic welding.
- Filter bag especially if it consists of foil to produce.
- the welding can be further complicated if the holding plate has a mechanism for automatically closing a flap when removed from the vacuum cleaner.
- These mechanisms have different metallic springs anchored in the retaining plate. In the area of these often positive anchors are high material thicknesses precede the ultrasonic line. The spring itself often leads to an unwanted distribution of ultrasound in the workpiece so that at the actually desired Versch bridgeposition not enough energy is available.
