Methods for manufacturing a panel for a ball, in particular for a soccer ball, as well as panels manufactured by these methods and balls with such panels. A method comprises the following steps: providing a carrier material having an outer side and an inner side within a mold having at least one first and at least one second mold part. Three-dimensionally molding an outer layer of the panel on the outer side of the carrier material within the mold. Three-dimensionally molding an inner layer of the panel on the inner side of the carrier material using at least the first mold part.

An article comprises a cushioning assembly which includes a first bladder element forming a first fluid chamber, and a second bladder element within the first bladder element and forming a second fluid chamber sealed from and within the first fluid chamber. The first bladder element comprises an inner surface having a first feature. The second bladder element comprises an outer surface having a second feature. The first feature interfits with the second feature such that a first area of the inner surface of the first bladder element is aligned with a first area of the outer surface of the second bladder element at a bonded interface. The second bladder element is exposed to the first fluid chamber away from the bonded interface. A method of manufacturing the article includes interfitting the first feature with the second feature and bonding at the bonded interface.
摘要:
A sport ball may include a casing, a bladder, and a component. The casing forms at least a portion of an exterior surface of the ball, and the bladder is located within the casing. The bladder includes a pocket that projects toward a center of the sport ball, and the pocket defines a cavity. The component, which may be an electronic device or a counterweight, is located within the pocket. In some configurations, the bladder may include a valve that is located on an opposite side of the bladder from the pocket and component.
摘要:
An American style football including an inflatable prolate spheroidal shaped bladder, a lining positioned over the bladder, a cover assembly, a lacing, and an electronic circuit positioned between the lining and the cover assembly and generally aligned with the lacing. The cover assembly includes at least first, second, third and fourth cover panels collectively positioned over the bladder and the lining. The lacing is coupled to the first and fourth cover panels. The electronic circuit includes at least one sensor and the electronic circuit is configured to produce a signal to enable at least one characteristic of the football to be monitored during use.
摘要:
The present disclosure relates to a game ball and methods for stitching a thread with a high coefficient of friction upon a stripe member present on the game ball. At least one stitching is thus formed upon the stripe member. The stitching formed from the thread enhances the grip and/or spin characteristics of the resulting game ball, improving handling and playability.
摘要:
A sports ball having a high-performance cover formed from a plurality of embossed panels. The panels embossed at 2-3 mm from the edges of each of the panels. High tension stitching applied at the embossed regions for formulating a high performance soccer ball.
摘要:
A basketball including a carcass, cover panels, and cover strips. The carcass has an outer surface defining a first set of channels and cover panels regions between the first set of channels. The panels are respectively positioned over the panel regions and are spaced apart from each other. The strips are positioned over the channels. The strips have inner and outer surfaces extending between first and second sidewalls. The strips have a thickness that is measured radially from a centerpoint from the inner to the outer surface, and a width that is measured from the first to the second sidewall. At least one groove is formed into the outer surface. The groove has a width that extends between 20 to 70 percent of the width of the strip and has a maximum depth from the outer surface that is at least 50 percent of the maximum thickness of the strip.
摘要:
A sports ball having a high-performance cover formed from a plurality of panels with attached foam backing. The panels may be stitched together at stitch lines which are 2-4 mm from the edges of each of the panels. During manufacturing, before compression is applied, foam attached to outer layers for each of the panels may be a distance 2-6 mm away from the stitch lines. Foam attached on the inside of the sports ball may provide support and a robust round shape for manufacturing of a high performance sports ball.

摘要:
A ball includes a core, a cover, and cracking element or cracking layer. The cracking layer may be deformed or actuated to create discontinuities in the cover. The creation of discontinuities allows for easier recycling of the ball parts. The cracking layer may include one of a bladder or a hydrophilic material that expand upon the introduction of a fluid, a shape memory polymer that deforms upon application of a stimulus, or two materials that react chemically to form a gas.
