THREE-DIMENSIONALLY THERMO-MOLDED FOOTWEAR
Articles of footwear including a thermo-molded upper having a skin composed of one or more low melting point thermoplastic polymers. The skin may include at least one of: a base layer composed of a low melting point thermoplastic polymer and a grid layer including a yarn composed of a low melting point thermoplastic polymer. The uppers may be formed by placing a skin and an inflatable bladder into a mold cavity and heating the mold to a predetermined temperature. The inflatable bladder may be inflated such that the skin is pressed against an interior surface of the heated mold cavity to cause the skin to take on the shape of the internal surface of the mold cavity, thereby forming an upper for an article of footwear.

CONTROLLED SHEAR VACUUM FORMING FOR SHAPING PREFORMS
A controlled shear vacuum forming method that includes forming a three-dimensional (3D) structure from a preform material on a molding tool using restraints during vacuuming to prevent wrinkling. The restraints are withdrawn during vacuuming to allowing the preform material to come into contact with the sidewalls of the molding tool in a gradual manner. Such forming method is particularly suitable for forming wing spars with bent sections and/or curved contours.
Constrained Forming of Contoured Composite Hat Stringers
Cap wrinkling in a contoured composite hat stringer is reduced by constraining the cap as the hat stringer is being formed from a flat composite charge. The cap is constrained by an inflatable bladder placed in a tool set used to form the composite charge.

Method and apparatus for forming three-dimensional curved surface on laminated substrate, and three-dimensional curved laminated substrate
A method for forming a three-dimensional curved surface on a laminated substrate is provided. In the method, the laminated substrate is brought into close contact with an elastic sheet. Here, the laminated substrate comprises a support substrate and a conductive layer on the support substrate, and the support substrate comprises a resin substrate comprising a thermoplastic resin. The elastic sheet is deformed while the laminated substrate is in close contact with the elastic sheet. The laminated substrate is brought into close contact with a temperature-controlled mold to soften the resin substrate.

Conduction heating for HVA lamination process
A method of laminating a contoured part including heating a flexible membrane, positioning the heated flexible membrane into thermal contact with the contoured part, maintaining the heated flexible membrane in thermal contact with the contoured part to raise a surface temperature of the contoured part, moving the flexible membrane out of thermal contact with the contoured part, positioning a laminate between the flexible membrane and the contoured part, conforming the laminate to a surface of the contoured part, and heating the conformed laminate and contoured part to adhere the conformed laminate to the surface of the contoured part. The laminate may be conformed to a surface of the contoured part by applying a vacuum between the flexible membrane and the contoured part.
DEVICE AND METHOD FOR FORMING A FUNCTIONAL FILM INTENDED TO BE LAMINATED ON AN OPTICAL ARTICLE
A film structure comprising at least a functional film (212), a carrier layer (20), and a counter-force liner (22), said a functional film (212) being in between said carrier layer (20) and said counter-force liner (22). The carrier layer (20) and the counter-force liner (22) are larger than the receiving area, and the film structure comprises fastening means adapted to fasten, directly or indirectly, the counter-force liner (22) to the carrier layer (20) at least on a portion of a zone outside the functional film (212). It is also proposed a corresponding machine, optical device and method for forming a functional film intended to be laminated on an optical article.
COMPOSITE STRUCTURES AND METHODS OF FORMING COMPOSITE STRUCTURES
Composite structures and methods of forming composite structures are provided. The composite structures can include one or more composite structure components.
