Embodiments herein include a system for joining components. The system can include a rotating base platform, a plurality of receptacles mounted to the base platform, and a rotating sonotrode platform. A plurality of sonotrodes are mounted to the sonotrode platform. Each sonotrode can correspond to a receptacle. Each sonotrode can move in a reciprocating motion between a release position distant from a corresponding receptacle and a compressing position proximal to the corresponding receptacle. The compressing position occurs at a first angular position of the sonotrode platform. Each sonotrode is energized at the compressing position.

An ultrasonic systems and methods for sealing complex interfaces or for metal forming. Complex interfaces, such as a Gable top, have multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. An example system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Another example system includes two ultrasonic transducers synchronized in frequency and phase and used to vibrate a horn mechanically to facilitate a sealing or welding interface or to assist in a metal-forming process.

An energy apparatus can be configured for providing energy to an item being transferred over a rotatable drum. The energy apparatus can include a first energy mechanism configured to be fixedly coupled to the rotatable drum and rotate with the rotatable drum. The energy apparatus can also include a second energy mechanism configured to rotate around a circumference of the rotatable drum. The energy apparatus can additionally include a translation system coupled to the second energy mechanism and configured to move the second energy mechanism to an end position that allows the second energy mechanism and the first energy mechanism to provide energy to the item while there is no relative motion between the first energy mechanism and the second energy mechanism. Methods of providing energy to an item utilizing an energy apparatus are also disclosed.

A method of applying a lid (1) onto a neck (9) of a container (10), the lid (1) having a side wall (3) extending around an axis and an end wall (2) extending transversely to said axis, comprises the following steps: —positioning the lid (1) onto the neck (9); —exerting on the end wall (2) a force directed towards the container (10), so as to level the lid (1) on the neck (9); —screwing the lid (1) onto the neck (9) by rotating the lid (1) in a screwing direction.

A welding head comprises a welding element (51) for welding a lid (1) to an opening device of a container (10). The welding head (43) further comprises a 5 compensating device (62) operable for compensating a misalignment between the welding element (51) and the lid (1), thereby centering the welding element (51) relative to the lid (1).

The invention relates to a sealing device (100) and a method for heat sealing packaging material for producing sealed packages. The invention also relates to a filling machine. The sealing device (100) comprises a first jaw (110) comprising an electromagnet (112), and a second jaw (120) comprising a magnetic element (122). The second jaw (120) is arranged opposite to the first jaw (110) to form a gap adapted to receive the packaging material, such that the first jaw (110) and the second jaw (120) are attracted to each other upon actuation of the electromagnet (112) to close the gap and clamp the packaging material between the first jaw (110) and the second jaw (120).

An apparatus for capping a container (10) comprises: a conveying device for conveying the container (10) along a path; an applying head (23) for applying a lid (1) onto a neck (9) included in an opening device of the container (10); a welding head (43) arranged downstream of the applying head (23), the welding head (43) comprising a welding element (51) for welding the lid (1) to the opening device.

A welding head comprises a welding element for welding a lid to an opening device of a container, a supporting body for supporting the welding element and a compensating device for compensating a possible mutual mispositioning of the welding element and the lid during welding of the lid to the opening device, the compensating device being interposed between the supporting body and the welding element, the compensating device comprising a planar spring arrangement provided with at least one planar spring element having a first member and a second member mutually connected by deformable elements.

An applying unit for applying lids to necks of containers may be provided. The applying unit may include a conveying device configured to advance the containers along a path in an advancement direction; a group of applying heads, each applying head configured to screw a lid onto a corresponding neck; and a movement device configured to move the group of applying heads along the advancement direction, so that each applying head may be coupled to a corresponding neck along a portion of the path. The movement device may be configured to act on a common support element configured to support the applying heads of the group, so as to synchronously move the applying heads along the advancement direction.
