Methods and apparatuses for manufacturing portions of absorbent articles may include or facilitate conveying a substrate through a nip formed between a first device and a second device, transmitting vibrational energy from the second device toward the first device via the nip to alter the substrate, and cooling the second device by transferring thermal energy from the second device.

An ultrasonic welding apparatus includes a sonotrode comprising a structured working surface that comprises a plurality of apexes, a plurality of nadirs between immediately adjacent ones of the apexes, and planar sidewalls that extend between the nadirs and the apexes, and for each of the apexes the planar sidewalls on either side of the respective apex extend along first and second planes that intersect one another at an acute angle.

In a method of applying a weld to a target surface, a guide rail arrangement is attached to the target, the guide rail arrangement including at least one guide rail. A weld head carriage having a carriage housing, a rail follower assembly, and a sonotrode is movably mounted to the guide rail arrangement so that the follower assembly engages each guide rail for movement there-along. The weld head carriage is positioned adjacent the target surface, feedstock material is deposited onto the target surface, and the sonotrode is extended to engage the deposited feedstock material and apply a welding force to the feedstock material and the target. Relative movement between the carriage and the guide rail arrangement is initiated and ultrasonic vibrations are conducted into the feedstock material and the target, thereby welding the feedstock material to the target surface.

A welding device (10a; 10b) for welding an outlet element (12a; 12b) to a packaging material (14a; 14b) has at least one anvil (16a; 16b) comprising at least one receiving region (18a; 18b) for receiving the outlet element (12a; 12b) that is to be welded, has a holding element (20a; 20b) which the anvil (16a; 16b) is arranged on, and at least one welding die (22a; 22b), in particular a sonotrode, which is configured to interact with the anvil (16a; 16b) for a welding of the outlet element (12a; 12b) to the packaging material (14a; 14b), wherein the welding device (10a; 10b) comprises at least one support unit (24a; 24b) for supporting the anvil (16a; 16b), comprising at least one movably supported support element (26a; 26b), which is configured to exert a holding force onto the anvil (16a; 16b) in a welding operation state of the welding die (22a; 22b).

An ultrasonic metal welding device for welding electrical conductors using a compression chamber that is adjustable at least n height and that is delimited on opposite sides by a section of a sonotrode as a first delimiting surface and by at least one section of a counter electrode (156) as a second delimiting surface, wherein for welding, the counter electrode and the sonotrode are displaced relative to one another. The counter electrode used is one that comprises sections (152, 154) of geometrically different working surfaces or is composed of at least two sections that are displaceable relative to one another.

The present invention concerns an ultrasonic welding installation comprising an ultrasonic vibration unit having a sonotrode and a converter, wherein the sonotrode and the converter are arranged in mutually adjacent relationship along a longitudinal axis and the ultrasonic vibration unit can be caused to resonate with an ultrasonic vibration in the direction of the longitudinal axis with a wavelength λ, wherein there can be provided an amplitude transformer arranged between the sonotrode and the converter, wherein there is provided a holder for holding the ultrasonic vibration unit. To provide an ultrasonic welding installation having a holder which allows simple adjustment of the ultrasonic vibration unit and simple replacement thereof it is proposed according to the invention that the holder has a clamping device which is reciprocable between an opened position in which the ultrasonic vibration unit can be removed from the holder and a closed position in which the clamping device comes into contact with the ultrasonic vibration unit and exerts a force on same so that the ultrasonic vibration unit is held.

An ultrasonic horn (50) includes: a vibration source part (53) to which an ultrasonic vibrator (58) is mounted; a tip end part (56) to which a capillary (18) is mounted; and an intermediate part (54) which is interposed between the tip end part (56) and the vibration source part (53) and propagates vibration generated by the ultrasonic vibrator (58) to the tip end part (56).
