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.

A product processing apparatus that performs packaging or box packing of products is disclosed. The product processing apparatus includes a storage component and a display component. The storage component is configured to store settings relating to the packaging or the box packing of the products. The display component is configured to display adjustment-requiring parts that requires adjustment in the product processing apparatus when changing the settings.

A head for a horizontal flow wrapper packaging machine for forming a bandolier of product packages. The head includes a rotatable first shaft having a plurality of knife elements each including a blade and first and second upper crimping elements. The head also includes a rotatable second shaft having a plurality of anvil elements. A rotation speed of the second shaft is independent of the rotation speed of the first shaft. Each anvil element includes perforation and cutting surfaces and first and second lower crimping elements. A rotation speed of either the first shaft or second shaft is changed to move either a knife element or an anvil element, respectively, between a perforation position and a cutting position. The first upper and first lower crimping elements and the second upper and second lower crimping elements also mate to crimp the packaging material in either the perforating or cutting positions.

A fill-packaging method for plural rows, a fill-packaging machine for plural rows and a fill-packaged body include a wide-width cylindrical body forming process for continuously longitudinal-sealing a plastic film longitudinally unreeled in the longitudinal direction to continuously form a single wide-width cylindrical body, a sealing and cutting process for continuously heat-sealing one or more widthwise positions of the wide-width cylindrical body to form longitudinally border sealed portions and continuously cutting the longitudinally border sealed portions in the longitudinal direction to cut out the wide-width cylindrical body into a plurality of narrow-width cylindrical body rows independently arranged in parallel, and a bag-making process for continuously manufacturing packaged bodies by applying horizontal sealing to each of the narrow-width cylindrical body rows separated and run independently in the longitudinal direction at predetermined intervals while filling a packing material therein.

A bag-making and packaging apparatus includes a bag-making and packaging unit, a film feeding unit, a splicing device, and a control unit. The control unit allows a bag-making operation to continue by utilizing an auto-feeding function that feeds to the bag-making and packaging unit a film F spliced by the splicing device to take the place of a film F currently being fed to the bag-making and packaging unit. When the control unit judges that at least one of the film feeding unit and the splicing device is malfunctioning in a case where the control unit is utilizing the auto-feeding function, the control unit stops the auto-feeding function and executes a non-auto-feeding mode. The non-auto-feeding mode allows the bag-making operation to be continued by the bag-making and packaging unit and a film roll holding unit that is operable among plural film roll holding units.

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.

The film sealing and wrapping machine with a rotary cut and seal jaw is provided. The rotary cut and seal jaw has an internal sliding mechanism which provides for smooth and quiet operation. The rotational speed of the jaw may be varied to increase through put and to provide for a title bag around products. The rotary cut and seal jaw may comprise a seal bar and pressure pad may both be spring loaded to self align the seal bar and pressure pad during the sealing and cutting process. Lastly, a gap defined by a belt disposed upstream and downstream of the seal bar and pressure pad may be mechanically linked to the pressure pad through a control carriage.

The present invention relates to a method for portion-packing of an oral pouched snuff product (1′, 1″). The method comprises a) supplying and advancing a tubular web (19, 19′, 19″) of packaging material enveloping a continuous feed (23, 23′, 23a″, 23b″) of filling material in a direction of travel (L), b) forming transverse seals (39) in the tubular web across the continuous feed of filling material by means of ultrasonic welding, the transverse seals extending in a transverse direction (T) being perpendicular to the direction of travel. The present invention further relates to an arrangement (17, 17′, 17″) for portion-packing of an oral pouched snuff product.

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.

A rotary impulse sealer for forming a series of discrete bonds in a bondable material. The rotary impulse sealer has a roller rotatable about an axis. The roller has a roller body and a plurality of seal bars extending radially outwardly from the roller and spaced apart around the roller body. At least one of the seal bars has a body and a selectively heatable heating element extending along at least a part of a length of the seal bar body. The roller is rotatable through a pre-heating pressure application region in which the at least one seal bar is adapted to apply pressure to a bond area of the bondable material, followed by a heating region in which the at least one seal bar is adapted to heat the bond area, the regions being stationary with respect to the rotation of the roller. A method of forming packages containing fluid or fluent material includes continuously providing at least two sheets of bondable material having a fluid or fluent material therebetween, applying pressure to a transverse bond area of the bondable material to force the fluid or fluent material away from the transverse bond area, and heating the transverse bond area to form a seal.
