摘要:
A fluid-filled chamber (33,40), which may be incorporated into articles of footwear (10) and other products, may include an outer barrier (40) and a tensile element (50). The outer barrier (40) may have a first portion, an opposite second portion, and an interior surface defining an interior void. The tensile element (50) may be secured to the first portion of the outer barrier (40) in a plurality of first bond areas (55,56) and may be secured to the second portion of the outer barrier (40) in a plurality of second bond areas (55,56). Each of the bond areas (55,56) may be connected to portions of the tensile element (50) spaced from the interior surface.
摘要:
A fluid-filled chamber, which may be incorporated into articles of footwear and other products, may include an outer barrier, a first tensile structure, and a second tensile structure. Any of the first and second tensile structures may include one or more textile tensile members. The first and second tensile structures may be located within an interior void defined by the outer barrier and may be bonded to the outer barrier. The first and second tensile structures may be bonded to the outer barrier in different areas of the outer barrier that are in fluid communication with each other. The first tensile structure may have a height greater than a height of the second tensile structure. In turn, the relative locations and differences of height between the tensile structures may impart a contour to the chamber.
摘要:
A method for producing a regionalized-firmness midsole utilizing a heat process, the method comprising: providing a plurality of plates, wherein the plurality of plates forms a receiving area; providing a first quantity of pelletized phylon (a compression-moulded EVA foam); providing a second quantity of pelletized phylon, wherein the first quantity of pelletized phylon having a first density and the second quantity of pelletized phylon having a second density; dividing the receiving area into a first zone and a second zone; placing the first quantity of pelletized phylon into the first zone; placing the second quantity of pelletized phylon into second first zone; and integrating the first quantity of pelletized phylon and the second quantity of pelletized phylon to form the regionalized-firmness midsole by heat activation.

The invention relates to systems and methods for creating a foamed part. An example method includes providing a polymer processing system, providing a mold having at least one expandable mold cavity in fluid communication with the polymer processing system, mixing polymeric material and blowing agent within the polymer processing system to produce a unfoamed mixture, injecting a volume of the mixture of polymeric material and blowing agent from the polymer processing system and into the expandable mold cavity, and expanding the mold cavity to expand the unfoamed mixture within the mold cavity and form a foamed preform. Thereafter, the foamed preform may be inserted into a compression mold to press-form the foamed preform into a finished part.
摘要:
Microwave energy is used to affix an ethylene-vinyl acetate (“EVA”) item to a rubber item by placing an at least partially cured EVA item in contact with a less than cured rubber item forming a bi-component member. The bi-component member is enclosed in a cavity formed from a material having a first dielectric constant less than or equal to a second dielectric constant of the partially cured EVA item. Microwaves and pressure are applied through the cavity to the at least partially cured EVA item and the less than cured rubber item for a predetermined amount of time to cause the affixing of the portions forming the bi-component member.
