ABSTRACT:
An ultrasonic welding device includes a sonotrode emitting vibratory energy and an anvil having a work face cooperating with the sonotrode for supporting a workpiece positioned for welding between the sonotrode and the anvil. The anvil has a housing and a plurality of laminae individually shiftably supported in the housing in a face-to-face relationship for forming a lamina stack. Each lamina has an edge face at a side of the lamina stack; the edge faces together constitute the work face of the anvil. There is also provided a force exerting arrangement for imparting individually to each lamina a force oriented towards the sonotrode for individually urging each lamina outwardly of the housing in the direction toward the sonotrode.
