Abstract
The invention concerns an ultrasonic welding device, which is more fully integrated by adjacent components of coupling surface. In order to permit a adequately fixed connection between the components, while, at the same time simplifying the mounting, it is suggested that at least some of the integrated components (30, 34) are structured in their coupling surfaces (40, 42), which lie on top of each another, for the achievement of a form closure.

Welding device, in particular an ultrasonic welding device, fully integrated by adjacent components of coupling surfaces (40, 42, 56, 58, 66, 68), such as a sonotrode (16), booster and converter, sonotrode and sonotrode head or working parts of a limiting multipart anvil of a compression chamber (10),
- characterized in that
- at least some of the integrated components (30, 34, 46, 48, 60, 62) are structured in their coupling surfaces (40, 42, 56, 58, 66, 68), which lie on each other, for achieving a form closure.
Technique for welding elongated, linear-shaped workpieces by means of an ultrasonic welding device containing a compression chamber, which admits workpieces, and which is delimited by a sonotrode section, an opposite anvil section, as well as lateral limiting component, from which, by setting, the width of a compression chamber can be adjusted, whereby the
- workpieces are first placed in the compression chamber, which is uncovered, or partially uncovered by the anvil section, so than the compression chamber can be adjusted to the total transverse section of the workpieces to be welded and the workpieces can be subsequently welded by sonotrode excitation,
- characterized in that
- if M workpieces (where M≦4) are welded, the width of the compression chamber is adjusted in such a way that the workpieces, when placed, are positioned above each other in the compression chamber, and that then, if N workpieces (where N>4) are welded, the width of the compression chamber is adjusted in such a way that, the workpieces, when placed, are positioned both beside each other as well as above each other.
