An apparatus for bonding separators in electrical devices the separators to each other so as to sandwich an electrode, includes a transmission unit configured to generate ultrasonic oscillations, an amplifier unit configured to amplify the generated oscillations, an abutting part configured to apply the amplified oscillations to the separators so as to bond the separators to each other, and separator conveyance units configured to convey the separators to a bonding position where the abutting part bonds the pair of separators to each other, the transmission unit, the amplifier unit, and the abutting part are laid out parallel to a direction in which the separators are conveyed.

Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. A folded insert disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.

An apparatus for fabricating an elastic nonwoven material generally includes a first bonding module and a second bonding module. The second bonding module is positionable in close proximity to the first bonding module for receiving a first nonwoven fabric, a second nonwoven fabric, and at least one elastic strand therebetween. The second bonding module has a face with a width dimension and a circumferential axis and is rotatable about a rotation axis. The face has a plurality of ridges includes a first ridge and a pair of second ridges positioned on opposing sides of the first ridge along the circumferential axis. The first ridge defines a plurality of interspaced lands and notches, and the second ridges are configured to sever the at least one elastic strand when in close proximity to the first bonding module.

The present invention is intended to prevent cutting of the resilient and elastic members by a welding process. The foregoing issue is solved by passing a first sheet layer, a second sheet layer, and elongated resilient and elastic members continuously disposed in an MD direction between the two sheet layers, between a first roll with joint convex parts provided at circumferential intervals on an outer peripheral surface and a second roll opposed to the first roll, and pressurizing and heating the first sheet layer and the second sheet layer to form sheet joined sections by welding the first sheet layer and the second sheet layer in such a manner as to cross the resilient and elastic members and have MD-direction intervals therebetween, wherein circumferentially continuous grooves are formed on a pressurization surface of the second roll, passage sections of the resilient and elastic members are pressurized and heated in positions including the grooves of the second roll, and non-passage sections of the resilient and elastic members are pressurized and heated in positions not including the grooves of the second roll.

A device for producing a packaged electrode includes: a conveyance unit configured to sequentially overlay the electrode and the pair of separators from a front end side in a conveying direction while conveying the electrode and the pair of separators; a first joining chip configured to join lateral edges of the pair of separators together; at least one second joining chip positioned downstream of the first joining chip in the conveying direction and configured to join the lateral edges of the pair of separators together. Front ends of the lateral edges of the pair of separators being sequentially overlaid while being conveyed by the conveyance unit are joined together by the first joining chip positioned upstream before the front ends are conveyed to the second joining chip positioned downstream.

The technology described herein relates to breathable, vented, and insulating garments. More particularly, the technology described herein relates to articles with a plurality of interconnected chambers that are configured to retain a thermally insulating fill material such as down or synthetic fibers. The plurality of interconnected chambers are formed between at least two layers of material and between a plurality of seams. The plurality of seams are configured to join the at least two layers of material together. In one aspect, each seam of the plurality of seams is angularly oriented with respect to an adjacent or neighboring seam of the plurality of seams. One or more openings or perforations may be formed on one or more seams of the plurality of seams forming the plurality of interconnected chambers. The one or more openings may achieve evaporation of moisture and/or air transfer from an interior environment of the garment to an exterior environment.

A process of manufacturing a waterproof enclosure and sealing the waterproof enclosure includes the steps of forming a rectangular waterproof upper member and a rectangular waterproof lower member; forming four rectangular adhesive members; securing the adhesive members to the lower member by pressing and heating; securing three edges of the upper member to the lower member by pressing and heating to form a partially open enclosure having an open edge; punching a plurality of positioning holes on a periphery of the partially open enclosure; placing an article in the partially open enclosure by inserting the article through the open edge of the partially open enclosure; sealing the open edge of the partially open enclosure by pressing and heating to form a sealed enclosure; and cutting the periphery having the positioning holes to finish a waterproof enclosure.

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 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.

An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.
