摘要： A sonotrode for the ultrasonic welding of materials is described, wherein a discoidal body (50) rotating about an axis of symmetry (Z) comprises a peripheral welding surface (52) adapted to be brought in contact with materials to be welded, a pair of pins (51) for connecting said body (50) to driving or balancing members, and a pair of opposite faces (53) each having a peripheral portion joining said welding surface and an inner portion joining one of said pins. The pins are surrounded by a substantially smooth annular groove (55).

摘要： The invention relates to a rotary horn for ultrasonic welding of materials, wherein the discoidal body (8) has a pair of opposite outer faces (9, 10) which are profiled in a manner such that the minimum thickness (Smjn) of the discoidal body is at a minimal distance (Rmin) from the hub (4), said distance being in any case shorter than half the radial extension (Rd) of said faces.
