The present invention is a method for manufacturing inflatable bladders for use in articles of manufacture. The method includes the steps of providing a first polymer film, applying a curable release coating to the polymer film in a pattern that corresponds to the configuration of the inflatable bladder, curing the release coating to the first polymer film, providing a second polymer film with the first polymer film to form a layered element such that the release coating is disposed between the polymer films, positioning the layered element between two plies of material, applying heat and pressure to adhere the polymer films together except in the area where the release coating has been applied to form an inflatable compartment surrounded by a sealed perimeter, and removing the plies of material from the adhered first and second polymer films.

A packaging machine to make an airtight wrapper includes a wrapping sheet wrapped airtight around a structured assembly consisting of an organized group of smoking articles associated with a reinforcement insert. The reinforcement insert includes, in working sequence on one or more cyclical conveyor devices of the wheel or carousel type, a structured assembly formation unit, a combination unit suitable to combine the structured assembly with said wrapping sheet, a wrapping sheet work unit and a welding unit.

A radome for housing a radar system comprises a plurality of interconnected curved radome thermoplastic composite material panels, each curved radome thermoplastic composite material panel having a plurality of interconnecting edges, a foam core, an inner skin, an outer skin, and a plurality of three-dimensional fiber bundles tying the inner skin and the outer skin to each other through the foam core, inhibiting delamination. The radome includes a hydrophobic exterior surface that is self-cleaning and requires zero maintenance for 25 years.

A method for manufacturing a metal-resin joint 30 according to the present disclosure is a method for manufacturing the metal-resin joint 30 in which a synthetic resin member 10 made of thermoplastic resin and a metal member 20 made of metal are bonded to each other, the method including: a first process of exposing a surface 12 of the synthetic resin member 10 molded into a predetermined shape, to air heated to a first temperature T1 equal to or higher than a deflection temperature under load Tf of the thermoplastic resin when a load of 1.8 MPa is applied; and a second process of bonding the surface 12 of the synthetic resin member 10 and a surface 22 of the metal member 20 to each other. Accordingly, it is possible to improve the bonding strength between the metal member 20 and the synthetic resin member 10.

A sonotrode includes multiple layers of a material melted to one another to form a structure. The structure provides a base that has an attachment feature that is configured to operatively secure to an ultrasonic converter. The structure includes a shaft that extends from the base to a terminal end that provides a working surface that is configured to selectively engage a workpiece. The structure has at least one shaft that includes a first shaft that extends from the base to a first terminal end that provides a first working surface that is configured to selectively engage a workpiece. The first shaft is integrally formed with the base from the multiple layers to provide an unbroken, monolithic construction.

Manufacturing capsules, comprising preparing a first and a second capsule element, at least the first element containing a cavity, each element, being provided with a peripheral ring, bringing the elements together, so that the rings are superimposed, placing the two elements between a sonotrode and an anvil, the anvil containing an anvil recess and a striking surface, surrounding the anvil recess, the sonotrode including a sonotrode recess, with the same cross-section as the anvil recess, and a working surface surrounding the sonotrode recess, wherein the striking and working surfaces are configures to come into contact with each other on a working area, extending around the recesses, clamping the rings between the working surface and the striking surface by the proximity of a sonotrode and the anvil, activating the sonotrode and directing the ultrasound towards the anvil, whilst maintaining the clamping action, wherein the rings are detached from the capsule.

An ultrasonic processing system adapted to subject a web running in a machine direction to ultrasonic processing includes a first mechanical element defined by one of an ultrasonic horn and an anvil and a second mechanical element defined by a remainder. The web placed on an outer peripheral surface of a rotary drum moves conforming to the drum in a machine direction. The first mechanical element is provided on the inner side of the drum and the second mechanical element is provided on the outer side of the drum. The first and second mechanical elements repeat a step of forward movement and a step of backward movement in a direction intersecting the machine direction across the web. In both steps, the first and second mechanical elements come in close contact with each other by the intermediary of the web and thereby subject the web to the ultrasonic processing.

An appliance for sealing elastic hoses with a sleeve, which is plastically deformable and slipped onto the hose, has two jaws which are movable towards and away from each other. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The same jaw has a cutting edge which projects towards the other jaw and is directed transversely of the sleeve, the cutting edge making a substantially transverse cutting indication in the sleeve and the hose when the jaws are moving towards each other.

A system and method for joining a plurality of paper material together with ultrasonic welding to form a hang tab for displaying products, such as, e.g., in a retail environment, without the use of an adhesive, such as, e.g., glue, and/or printing dye or ink. The paper hang tab may replace plastic hooks or tabs, which may be more environmentally beneficial. Two or more pieces of paper may be inserted into a gap between a sonotrode and an anvil of an ultrasonic joining device. A joining force from an actuator may be applied to secure the pieces of paper, and the sonotrode may oscillate a high-frequency. Adequate compaction of the pieces of paper is produced in addition to a high development of heat from friction generated in the micro-region of the thermoplastic coating. Melting of thermoplastic coating then forms a physical connection between the pieces of paper, effectively fusing them together.

A rotary device for welding a continuous web includes a rotary element, support elements for supporting the web, supported by the rotary element, and a plurality of welding units for welding the web. Each welding unit passes from a non-operating position to an operating position and vice versa, and includes a first movement device for commanding a relative rotation of an anvil element relative to a welding tip and a second movement device for moving the anvil element relative to the welding tip such that a contact surface of the anvil element and a contact surface of the welding tip make contact with a portion of the web in a zone between them, and vice versa. First and second drive mechanisms drive the first and second movement devices. The first and second drive mechanisms are configured to vary a positioning of the welding tip relative to the axis.
