Abstract:
1. Device for ultrasound processing of a strip or web of material, comprising: a sonotrode functionally associated with an ultrasound converter and carried by a first device body part on a first side of a working area, an anvil held opposite the sonotrode by a second device body part on the other side of the working area, the first device body part and the second device body part being displaceable relative to each other with a movement producing relative displacement of the sonotrode and of the anvil toward or away from each other, manually adjustable mechanical means disposed between a first connecting portion on the first device body part and a second connecting portion on the second device body part and having elastic means for spring-loading relative displacement the first connecting portion and the second connecting portion in the direction of relative movement toward each other of the sonotrode and the anvil in the working area, elastic bearing force adjustment means in the manually adjustable mechanical means for modifying the state of compression of the elastic means, abutment means in the manually adjustable mechanical means for limiting convergent movement which oppose relative displacement between the first connecting portion and the second connecting portion in the direction of relative movement toward each other of the sonotrode and the anvil short of a minimum separation whilst allowing displacement thereof in the opposite direction, a manual minimum separation adjustment member in the manually adjustable mechanical means for adjusting the position of the abutment for limiting convergent movement and thus adjusting the minimum separation, wherein, in the manually adjustable mechanical means, the abutment means for limiting convergent movement and the elastic means are in direct or indirect bearing engagement against the manual minimum separation adjustment member so that operation of the minimum separation adjustment member to modify the minimum separation does not modify the elastic bearing force produced by the elastic means.
