摘要:
The invention relates to ultrasonic welding of industrial fabrics. Specifically, the invention relates to methods for ultrasonically welding the seam area of industrial fabrics using a textured horn and/or anvil. The fabric edges are overlapped as woven or one or both edges can have some warp or weft yarns raveled out. The method involves ultrasonically bonding the overlapped fabric edges, reducing the caliper of the two stacked edges to match the body caliper of the fabric itself. The bonded area can then be perforated using laser or other mechanical means to produce a seam having the same woven texture and permeability (air and/or water) as the body of the fabric.

A sport ball may include a plurality of panels having a first surface and an opposite second surface, the first surface forming a majority of an exterior surface of the ball. In addition, the sport ball may include an interior layer secured to the second surface of the panels and forming substantially all of an interior surface of the ball to retain a fluid within the ball, the interior layer extending between the panels to join the panels together. Further the sport ball may include a valve secured to the interior layer.

The invention relates to a method for welding thermoweldable sheets of which at least one is made of polycarbonate. The method is characterized in that the sheets to be welded are separated from the metal electrodes (4,5) of the high frequency press by means of a glass plate (2,3). Application to the fabrication of high density magnetic cards.

A bladder includes a first polymeric film, a second polymeric film attached to the first polymeric film to form a chamber, and one or more grooves formed in an exterior surface of the chamber. In one configuration, the grooves are formed in the exterior surface of the chamber by subjecting the chamber to a laser-etching process.

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.

摘要:
An apparatus and method of manufacturing a plurality of air bags for use in a motor vehicle, and air bags made by same. First and second fabric layers of a type of fabric suitable for use in a vehicle air bag are fed into a seaming station. At the seaming station, the fabric layers are seamed together according to a predetermined seaming pattern so as to produce a composite textile structure defining a plurality of individual air bags to be cut therefrom. Depending on the application, the seaming may be accomplished by stitching or welding. If the fabric layers are not precoated, a suitable coating material may then be applied to both outer surfaces of the composite textile structure so as to render the air bags substantially impermeable to passage of air. Finally, the plurality of individual air bags are cut from the composite textile structure.
