  • Publication number: 20140059890
    Abstract: 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.

  • Publication number: 20140053968
    Abstract: The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second.

  • Patent number: 8652286
    Abstract: A stretchable appliqué made from a stretchable substrate with indicia thereon may be applied to a variety of articles including stretchable performance athletic wear. A method for making the stretchable appliqué may include applying an adhesive and a carrier layer to one surface of a stretchable substrate. Indicia may then be applied to the opposite surface of the stretchable fabric and the stretchable substrate may be cut to a desired shape to form the stretchable appliqué. The carrier layer may then be removed and the stretchable appliqué may be adhered to the desired article. The stretchable appliqué may be adhered to stretchable articles of apparel so that the appliqué may stretch when the article of apparel stretches. The carrier layer may be less stretchable than the stretchable substrate, including being completely non-stretchable.

  • Patent number: 8434244
    Abstract: A cushioning member for an article of footwear. The cushioning member is a flexible bladder having a fluidly interconnected heel chamber and forefoot chamber. The bladder is disposed above the sole and beneath the wearer's foot to provided added cushioning to the wearer. The bladder contains air at slightly above ambient pressure and can be formed by thermoforming or by welding two sheets of resilient, flexible material together. A connecting passage fluidly connects the heel chamber and the forefoot chamber. The connecting passage is narrow to control the flow of air between the two chambers.
