Abrégé

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.

Abrégé

A rotary sonotrode for ultrasonic cutting is described, which comprises a body ( 50) being radially symmetrical about an axis of rotation. The body has a pair of opposite faces ( 51, 51 ' ) which are peripherally joined together into a cutting edge ( 52 ) for cutting materials. The body is also provided with at least one arm (4 ), located at the centre of one of said faces and extending along the axis of rotation. The thickness of the sonotrode body in a radial plane about the axis of rotation decreases according to a strictly decreasing monotonic law from the arm to the cutting edge. The invention also relates to an ultrasonic cutting machine using said sonotrode.

Abrégé

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).
