The purpose of the system is to permit the employment of ultrasonic welding over extensive working areas, like for example the simultaneous sealing of a considerable number of containers set out in said area, with uniformity of sealing over the entire surface thereof, regardless of its size. To this end said system is based on the use of a battery of sonotrodes (1) pertaining to ultrasonic units functionally independent from each other, battery in which said sonotrodes are arranged forming a mosaic in which they are considerably close to each other, being separated by very reduced spaces (2). <IMAGE> |
