A method for manufacturing a laminated molded body includes a cutting-out step for cutting out a cushion layer to form a cut-out part; a base material laminating step for forming a first laminated body; an insulating material placing step of attaching an insulating material to the cut-out part; a first thermocompression bonding step for bonding the first laminated body by thermocompression; a removing step for removing the cut-out part to form an opening; a skin laminating step for forming a second laminated body; and a second thermocompression bonding step for bonding the skin at the opening part to the lower layer material by bonding the second laminated body by thermocompression, the lower layer material being arranged below the cushion layer having the opening part.

A respiratory apparatus may employ ultrasonic welds. The ultrasonic welding may be used to join a variety of headgear, mask and accessory components. This process may enhance comfort, fit and/or performance of the joined components and/or overall mask assembly. A component may be a single layer component such as a textile or fabric, or a composite or multiple layer component such as fabric and foam composites, or outer fabric layers and inner spacer fabrics. Further, a component may be a strap, some other headgear component, a mask component, an accessory component or the like.

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.

The present invention relates to breathable, vented, and insulating cold weather garments. More particularly, the present invention relates to garments with chambers to retain an insulating fill material. Perforations along the seams between the insulating chambers may achieve optimal evaporative moisture transfer from the inside (proximal to the body of a wearer) of the garment to the outside environment.

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.

Perforations along the seams between the insulating chambers may achieve optimal evaporative moisture transfer from the inside (proximal to the body of a wearer) of the garment to the outside environment.

An absorbent body forming satisfactory connections while webs are conveyed at a high speed includes at least two sheets of nonwoven fabric overlapping each other; connections at which the nonwoven fabric sheets are connected together; and an absorbent material disposed between the nonwoven fabric sheets at a small region encircled by the connections. When seen in a direction perpendicular to a main surface of the nonwoven fabric sheets, a plurality of the connections is formed with spaces therebetween on each side of imaginary polygons compartmentalizing the nonwoven fabric sheets and neighboring each other, and the connection is formed at least on a middle part of the sides common to the imaginary polygons neighboring each other. The connections are formed sequentially, and simultaneously arranged in a row parallel to each other, and the minimum number of connections per row is at least 45% of the maximum number of connections per row.
