Abstract
There is disclosed a sonotrode comprising: a head which defines a sealing surface elongated along a first direction orthogonal to a second direction and at least one first slot which extends through the head transversally to the first direction; the first slot extends parallel to a third direction inclined to both the first direction and the second direction; the first direction defines an acute angle with the second direction.
Claims16
A sonotrode comprising:
- a head which defines a sealing surface elongated along a first direction orthogonal to a second direction;
- and
- at least one first slot which extends through said head transversally to said first direction;
- wherein said at least one first slot extends parallel to a third direction inclined to both said first direction and second direction;
- said first direction defining a first angle with said second direction;
- said sonotrode further comprising a pair of second slots which extend along respective fourth directions inclined with respect to both said first direction and said second direction;
- and
- said fourth directions being symmetric with respect to a symmetry plane of said sonotrode parallel to said second direction and defining, each, a second angle with said plane.
