A system includes a first horn, a first ultrasonic transducer, a second horn, a second ultrasonic transducer, a memory, and a controller. The first horn includes a first part-interfacing surface. The second horn includes a second part-interfacing surface and is positioned relative to the first horn such that a part to be welded can be positioned between the first and second part-interface surfaces. The controller is configured to cause a first ultrasonic energy to be applied through the first horn via the first transducer to cause the first part-interfacing surface to vibrate, cause the first horn to move in a first direction at a first time, cause a second ultrasonic energy to be applied through the second horn via the second transducer to cause the second part-interfacing surface to vibrate, and cause the second horn to move in a second direction at the first time.

An anvil roll is configured to operatively engage with a tooling agent. The anvil includes an outer surface, an opposing surface opposite the outer surface and an inner surface. One or more spring elements are disposed between the opposing surface and the inner surface. The springs provide a compliance to the anvil.

A production machine for the production of collapsible pouches having a fitment. The machine has a fitment sealing station with an impulse sealing device comprising a first jaw and a second jaw and with an actuator device configured to move the first and second jaws relative to one another between an opened position and a clamped position, as well as a cooling device configured to cool each of the first and second jaws. The fitment sealing station is configured to perform an impulse sealing cycle.

An anvil is configured to operatively engage with a tooling agent. The anvil includes an outer surface, an opposing surface opposite the outer surface and an inner surface. One or more spring elements are disposed between the opposing surface and the inner surface. The springs provide a compliance to the anvil.

An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and an anvil. The anvil is positionable in close proximity to the horn. Either the horn or the anvil has a face with a width dimension and a circumference and is rotatable about a rotation axis. The face has a raised profile, and a height of the raised profile has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn and the anvil.

A package is provided that is formed from a packaging material, such as film, having increased adhesive in critical locations, such as adjacent folds in the end seal and other areas so that that the increased adhesive can at least partially fill voids adjacent such folds. The additional, localized sealant material is applied in a plurality of discrete locations in the end seal or other region adjacent where folds are formed and overlap with a sealant layer so as to provide additional sealant material for at least partially filling the voids without being present throughout the entirety, majority or large portions of the packaging material.

A welding station for producing a wrapping has a support wheel and a welding device housed on the support wheel and having a head assembly that has a welding member, a support body, and a rod axially movable between a retracted position and a forward position. The support body is integral with an axial end of the rod. The welding device has an abutment assembly having an abutment member and a base assembly engaged to the support wheel. The welding device is configurable in an open configuration where the head assembly and the abutment assembly are mutually spaced, the rod is axially retracted, and the abutment member allows the wrapping to be loaded onto and removed from the head assembly, and a welding configuration where the head assembly and the abutment assembly are mutually engaged, the rod is axially forward and the abutment is engaged by the welding member.

A fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers is provided. The fin sealer is configured to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller.

A vehicle tank, in particular for holding a fuel, in particular gasoline and/or diesel fuel, having: a first and a second partial shell, wherein the first and second partial shell are connected to one another in a partial shell joining area, and a barrier layer substantially, preferably completely, covering an outer surface of the first partial shell and an outer surface of the second partial shell, respectively, wherein the barrier layer spans the partial shell joining area on an outer surface of the vehicle tank.
