A sealing apparatus including a sealing tool that is movable between an inactive position and a sealing position. The sealing tool includes two actuating elements, each with a respective actuating surface that face each other. The actuating elements are configured to allow the passage of a packaging material therebetween and for transversely sealing the packaging material when the sealing tool is in the sealing position. The actuating surfaces are configured to cooperate with one another to perform the sealing. The actuating surfaces are also configured to cooperate with one another during the change in position of the sealing tool to the sealing position, and for transversely cutting the packaging material during the change in position.

A first thermoplastic component and a second thermoplastic component including a first joint portion and a second joint portion, respectively, are provided. A least a portion of a surface area of each of the first and second joint portions include a respective first and second mating surface. The first and second mating surfaces of the respective first and second joint portions are positioned in contact with one another. The first and second joint portions are fusion joined. Fusion joining the first and second joint portions forms a fused unitary portion of the first and second thermoplastic components.

Aspects of the disclosure relate to envelopes for aerial vehicle. The aerial vehicle may include an envelope including a plurality of gores. The aerial vehicle may also include a seal arranged between a pair of the plurality of gores, the seal including six layers of envelope material heat-sealed together.

Methods of producing polymer-metal hybrid components that are bonded by C—O-M bonds at the interface using at least one of the hot pressing, rolling, and injection molding methods to create chemical bond formation conditions at the polymer and metal interface. When the thermal cycle and compressive pressure specified herein is combinationally created at the polymer and metal interfaced, strong C—O-M bonds forms at the interface and strongly bonds the metal and polymer together through the reaction carbonyl groups (C═O) in polymer and the metal surface. For polymers lacking enough carbonyl groups, new functional groups can be in-situ generation through introducing distributed air pockets at the polymer-metal interface for forming 3-dimensional distributed C—O-M bonds at the interface.

A packaging device, particularly for packaging trays containing food products or technical materials in a controlled atmosphere and by means of a film of plastic material, comprising an upper chamber and a lower chamber, which can be fastened by mutually superimposing them and are each provided internally with a plurality of heat-sealing and/or cutting and/or die-cutting elements arranged concentrically, the lower chamber being provided centrally with a plurality of supporting elements for a tray.

A method for manufacturing an air bag includes forming a bag portion surrounded by a welded portion extending in an annular shape by pressing at least one welding mold against two sheet materials arranged to be stacked from a stacking direction of the sheet materials. The welding mold is pressed against the sheet materials to form the welded portion including a welding bead portion protruding to an inside of the bag portion between the sheet materials. A pressing surface of the welding mold against the sheet materials is provided with a slope portion facing in the stacking direction of the sheet materials and in a direction of the inside of the bag portion at a position further on an outside of the bag portion than a position at which the welding bead portion is formed.

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 method of manufacturing a heat exchanger array that includes stacking a plurality of heat exchanger units in an aligned configuration with respective first ports of the heat exchanger units aligned. The heat exchanger units can include a first and second sheet coupled together to define an cavity between the first and second sheets; the first port at a first end of the heat exchanger unit defined by the first and second sheets; and a second port at a second end of the heat exchanger unit defined by the first and second sheets. The method further includes stacking the plurality of heat exchanger units in an aligned configuration with the first ports of the plurality of heat exchanger units aligned and generating a first plurality of respective couplings between adjacent sheets of adjacent heat exchanger units about adjacent first ports. The coupling can be generated by an adhesive.

A bleach compatible mattress cover made of a non-woven polyolefin material and defining an interior cavity. The interior cavity configured to receive a mattress structure which may include a first and second support structure disposed in the interior cavity. In certain embodiments, the mattress cover has a Moisture Vapor Transfer Rate of greater than or equal 400 to less than 10,000, 7500 or more particularly less than 5000 grams per square meter per day and a hydrostatic head of 100 cm or greater and passes ASTM 1670 and ASTM 1671.

A process for packaging a product (P) arranged in a support (4) comprising unrolling a film (10a), transversely cutting the unrolled portion of film (10a) and preparing cut film sheets (18), moving the cut film sheets (18) to a packaging assembly (8) defining at its inside a packaging chamber (24), progressively moving a number of supports (4) inside the packaging chamber (24) of a packaging assembly (8), keeping the packaging chamber (24) open for a time sufficient for a number of supports (4) and for a corresponding number of film sheets (18) to properly position inside said packaging chamber (24), hermetically closing the packaging chamber (24) with the film sheets held above the respective support (4) and at a distance sufficient to allow gas circulation inside the support (4), optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber (24) and gas injection of a gas mixture of controlled composition, heat sealing the film sheet (18) to said support (4), wherein the cutting of the film (10a) into film sheets (18) takes place outside the packaging chamber (24) at a station remote from the location where the film sheets are coupled to the supports. An apparatus (1) for performing the above process is also disclosed.
