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.

The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.

A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

The lid portion has a first body, a first rib protruding from the first surface of the first body and extending along the first surface, and the storage section has a second body, a second rib protruding from the second surface of the second body and extending along the second surface. The first and second ribs have main welded portions welded at intersections crossing each other, and the lid portion and/or the storage portion has main welded portions extending from one of the first and second ribs to the other between the main welded portions adjacent to each other. The lid portion and/or the storage section has an auxiliary rib extending from one of the first and second ribs to the other between the adjacent main welded portions, and the auxiliary rib has a sub-welded portion that is welded to the other at the intersection with the other.

The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus [1] for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.

A pair of thermoplastic resin members are placed on an anvil. A pressing force of a tool horn vibrating ultrasonically in a direction not perpendicular to but along upper surfaces of the pair of thermoplastic resin members is applied to the upper surfaces. The application of the pressing force of the tool horn vibrating ultrasonically allows melting of a vicinity of the upper surfaces of the pair of thermoplastic resin members. A welded structure part is formed on an unwelded structure part, thereby welding the pair of thermoplastic resin members as an overlap structure including the welded structure part arranged on the unwelded structure part. The distance and positional relationship between the pair of thermoplastic resin members after the welding are unchanged before and after the welding. The surfaces, placed on the anvil, of the thermoplastic resin members are neither burned nor discolored.

Method of making a shaped article (5) comprising at least two parts (10, 15) wherein the first part comprises at least one projection (20) and the second part comprises at least one recess (22) by preparing said first part and said second part in a moulding process and joining the prepared first and second part together by engaging the at least one projection with the at least one recess to form said shaped article.
