A fluid-filled may include including an outer barrier, a tensile member, and a fluid. The tensile member may be located within barrier and formed from a textile element that includes a pair of spaced layers joined by a plurality of connecting members. A method of manufacturing the chamber may include locating a textile tensile member between two polymer elements. Pressure and heat are applied to the tensile member and the polymer elements in a first area and in a second area. The pressure is greater in the first area than in the second area. In addition, the polymer elements are bonded together around a periphery of the tensile member.

A hollow lineal profile ( 16 ) formed from a continuous fiber reinforced ribbon (“CFRT”) that contains a plurality of continuous fibers embedded within a first thermoplastic polymer matrix ( 6 ). To enhance the tensile strength of the profile, the continuous fibers are aligned within the ribbon in a substantially longitudinal direction (e.g., the direction of pultrusion). In addition to continuous fibers, the hollow profile of the present invention also contains a plurality of long fibers that may be optionally embedded within a second thermoplastic matrix to form a long fiber reinforced thermoplastic (“LFRT”) ( 4 ). The long fibers may be incorporated into the continuous fiber ribbon or formed as a separate layer of the profile. Regardless, at least a portion of the long fibers are oriented at an angle (e.g., 90°) to the longitudinal direction to provide increased transverse strength to the profile.

Принадлежит: Intex Recreation Corp

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.

An integrated process for making an inflatable laminated article comprises extruding a first film and a second film, followed by cooling the first film and the second film so that the films will not fuse to one another upon contact with each other. The films are then brought into contact with one another, and selected portions of one or both films are heated so that the films are heat sealed to one another in a selected area having a desired pattern. The unsealed area between the film provides inflatable chambers between the first film and the second film. An alternative process utilizes a film tubing in lay-flat configuration to produce a laminated inflatable article.

The invention relates to a method for producing hollow bodies from thermoplastic material and to an apparatus for carrying out the method. The method comprises the molding of at least two sheet-like preforms in web form of thermoplastic material into two complementary shells in a multi-part tool, which in a closed position forms a mold impression, and the joining together of the shells to form an essentially closed hollow body, the preforms being brought between the parts of the tool in an opened receiving position of the parts of the tool and the preforms being placed into the part-cavities by applying differential pressure and being at least partially molded in them into shells. The shells are joined together to form an essentially closed hollow body by closing the tool to form a closed mold impression. The method is distinguished by the fact that the preforms are molded in the part-cavities while the parts of the tool are located in the opened receiving position.

A method and system for hydraulic blow molding a container from a preform . A molding medium is injected into the preform from a nozzle during a first molding stage. In the first molding stage, the molding medium is injected so as to be specifically directed at a closed end of the preform . During the first molding stage, the preform is axially stretched in response to the force exerted on the preform by the molding medium. The molding medium is also injected into the preform during a second molding stage, where the molding medium is injected at a flow rate greater than a flow rate during the first molding stage. During the second molding stage, the preform is radially expanded into the shape of the container.
