Protective packaging longitudinal heat sealer

A protective packaging formation device is provided herein. The device includes an inflation assembly having a fluid conduit that directs fluid between overlapping plies of a polymeric web. The device also includes a driving mechanism that drives the film in a downstream direction. The device also includes a sealing mechanism that includes a thin film heater that heats the plies to create a longitudinal seal that seals the plies of film together. The driving mechanism drives the web such that the web slides across the heating assembly in a downstream direction to trap fluid between the plies.

Dual bonder

A system and method for producing a disposable undergarment, with the lateral edges of the undergarment bonded by means of an ultrasonic horn. When a blank is formed for an individual undergarment, the lateral edges of opposing edges of the blank will form the seam. When the edges are sealed together, a seam is formed. The individual undergarments may be later separated along the seams.

Method for the production of an insulating profile

A method for producing insulating profiles comprises manufacturing a profile body and a first functional element separately, and the profile body and the first functional element are supplied to an ultrasonic welding device, wherein the profile body and the functional element are connected to one another by a material bond by formation of a welded joint. The profile body and the functional element are brought together into a predetermined first cross-sectional geometry during formation of the welded joint and are thereafter guided in this cross-sectional geometry until the plastics material of the welded joint solidifies to such an extent that the profile body and the first functional element are fixed in the predetermined cross-sectional geometry.

Packaging apparatus and method

A packaging apparatus, in particular for packaging smoking articles, includes a wrapping device for wrapping a barrier film around an item to be packaged, such as a pack of smoking articles; and at least one sealing head having a contact surface for contacting the barrier film wrapped around the item and sealing the barrier film along a seam to form a protective enclosure around the item. The contact surface of the sealing head is at least partially discontinuous to provide a non-sealing region in the sealing head. In this way, the non-sealing region can be positioned to at least partially, and preferably wholly, overlie a frangible part or strip provided in the barrier film.

Welding head

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).

Method and device for connecting fibre-reinforced webs

Method and device for connecting two webs (1), reinforced with unidirectionally oriented continuous fibres, by ultrasonic welding, wherein the fibres are embedded in a matrix of polycarbonate and the webs have abutting edges that are substantially square and substantially flat, characterized by the following steps:arranging the webs abutting one another in the region of the abutting edges in a welding device between a sonotrode (2) and an anvil (3),welding the webs by means of ultrasound, wherein the sonotrode and the anvil exert pressure on the webs to be welded in the melting region between the webs and perpendicularly to the abutting edges of the webs,removing the welded-together webs (4) from the welding device.

Cold formed 3D cover glass articles and forming process to make the same

In some embodiments, a process comprises applying an adhesive layer to a substrate having a developable shape. The process further comprises initially applying a force to press a thin glass layer against the adhesive layer along a generation line. The generation line moves across the substrate to cold-form the thin glass layer into the shape of the substrate, while maintaining the application of force on areas of the substrate over which the generation line has passed. The application of force is maintained on areas of the substrate over which the generation line has passed until the adhesive cures.
