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.

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.

An ultrasonic machine tool comprises a stand that can be attached to a base plate. The machine furthermore has a vibration generator by means of which a working member can be driven, wherein the vibration generator is borne by a slide displaceably guided in the longitudinal direction of the stand. The slide is in turn borne by a linear drive attached to the stand. The vibration generator is located in the alignment of the adjustment path of the linear drive.

A method and a device are disclosed for making thin plastic films having two or more layers, which are subdivided and separated in the form of tubular bags for portioned reception of different products, wherein the plastic films are provided with welding seams running substantially transversely to the longitudinal direction with predetermined spacing between one another to form bag-like containers, and the containers are separated from one another by a cutting or separating process, the method being characterized by the steps: a) welding the films with predetermined spacing by means of an ultrasound welding process, maintaining a defined, film-dependent distance between a processing tool and a counter tool while welding; and b) separating the tubular bags welded in this way by means of a mechanical cutting process, with or without reduced ultrasound excitation at the point of the respective weld seams.

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.

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.

A sealing machine having a movable carriage assembly which utilizes a counterbalance and two servo motors is disclosed. The counterbalance allows high throughput operation without excessive mechanical vibration. The use of two servo motors allows independent control of the horizontal movement of the movable carriage assembly and the vertical movement of the jaws. The use of two servo motors also allows adaptation to articles or packages of various dimensions. In some embodiments, an optical sensor is used to detect the position of the package to be sealed, and the movement of the movable carriage assembly and the jaw is altered based on the detected position.

A pull-on garment (1) includes an outer cover (3) forming an outer surface of the garment, both lateral side edge portions of the outer cover in a front body portion F and both lateral side edge portions of the outer cover in a back body portion R being joined to each other to form a pair of side seals (4), a waist opening (8), and a pair of leg openings (9). Each of the side seals (4) includes a seal edge portion (41) where the edge portion (3F) of the outer cover (3) in the front body portion F and the edge portion of the outer cover (3) in the back body portion R are bonded to each other by a continuous linear fusion-bonded portion (40) extending in a longitudinal direction of the side seal (4). In a cross-section orthogonal to a direction in which the side seal (4) extends, the fusion-bonded portion (40) includes a narrow section (4F) which is formed at a middle portion thereof in the thickness direction Q and of which a width W along the inner-to-outer direction P is small. The narrow section (4F) includes broad sections (4A, 4B) which are provided on both sides of the narrow section (4F) in the thickness direction Q and of which the width W is larger than the width of the narrow section (4F).
