Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the materials utilized in the construction and method of manufacturing of a sport ball.

2. Description of Related Art

Conventionally, a variety of techniques are utilized in manufacturing a sport ball, such as hand-stitching, thermo-bonding, and machine stitching. The hand-stitching technique is comparatively extensive and requires a highly skilled labor force and prolonged manufacturing processes. Consequently, the hand-stitched ball is not cost efficient.

Thermo-bonded sport balls are manufactured within a relatively short time span by using machines, but as it is generally seamless, use of such a ball presents many disadvantages including loss of trajectory control over flight during play. Thus, the thermo-bonded ball could not gain popularity and fondness from many international professional players.

Machine-stitched balls are known for their cheap construction, machine stitching and low price. They have become successful in the market, and have gained popularity among the beginners and general public. Yet due to poor construction materials and consequently poor durability, the machine stitched ball cannot achieve the international standards of match/professional balls.

The present invention overcomes the many disadvantages present in the conventional ball technologies by utilizing distinctive construction materials, their specific arrangement within the layers, innovative techniques and highly optimized, automated machines for manufacturing the sport ball.

BRIEF SUMMARY OF THE INVENTION

The present invention relates to a DPS (dual pressure system) sport ball having distinctive construction material, their novel and specific arrangements, innovative techniques and method of manufacturing the same. The DPS sport ball incorporates two major construction components—a plurality of panels and a bladder, wherein the panels include specifically developed outer casing material bonded to multiple lining layers.

The bladder incorporated herein is a specially developed rubber bladder, which can additionally be thread wound or fabric wrapped to maintain robustness, round shape, and air retention within the ball.

During the manufacturing, the present invention utilizes highly automated and optimized machines for sheet laminating, sheet sizing, printing of panels, their debossing, cutting, die-punching, machine stitching, and their manual stitching, seam protection so that the ball manufactured is not only robust and round, but also has increased durability, quality, playability, controllability and has an excellent flight characteristics.

In an exemplary embodiment, the present invention is a DPS sport ball comprising a casing material that forms an exterior surface of the ball, a multiple lining system bonded with the casing material to form panels using highly efficient automated manufacturing processes, and a compatible bladder to maintain shape of the ball, wherein the panels are a majority stitched together on a highly optimized stitching machine and then manually stitched to finalize the product.

The casing material can be selected from the group consisting of environment friendly polyurethane (EPU), normal PU, water-borne PU dispersion (WPU), PU micro-fiber, PU high solid, and TPU (thermoplastic polyurethane).

The multiple lining system can comprise five lining layers.

The multiple lining system can comprise lining layers of foam and fabric with a specific arrangement, wherein foam and the fabric are bonded using a water-based natural adhesive.

A first lining layer can be a fabric selected from the group consisting of woven and non-woven fabric bonded to the casing material of the sport ball.

A second lining layer can be a compatible foam, wherein the foam is bonded to the first lining layer. The compatible foam can be a thermoplastic elastomer (TPE) foam.

A third lining layer can be a fabric selected from group consisting of polyester viscose, polyester cotton, and 100% polyester fabric, wherein the third lining layer is bonded to the second lining layer.

A fourth lining layer can be a compatible foam, wherein the fourth lining layer is bonded to the third lining layer. The compatible foam can be TPE foam. The dimension of the fourth lining layer can be less than the preceding layers.

A fifth lining layer can be a compatible foam, wherein the fifth lining layer is bonded to the fourth lining layer. The compatible foam can be TPE foam. The fifth lining layer can be lesser or equal in size of the bonded fourth layer. The fifth lining layer can be in the form of one or more patches. The shape of the fifth lining layer can be similar or different from the preceding layers. The fifth lining layer can be round in shape. The fifth lining layer can have a diameter in the range from 3.5 cm-5 cm. The fifth lining layer can contain one or more holes where in case of more, holes are different or similar in diameter or shape from one another. The fifth lining layer can contain a hole in the center of one or more patches. The diameter of the hole can be in the range from 0.7-2 cm.

All the lining layers can be bonded by a natural or synthetic adhesive. All the lining layers can be bonded by a water-based natural adhesive.

Each panel of the DPS can include an outer casing material and five lining layers. Each panel can have a particular shape and size. The panels can incorporate a shape selected from the group consisting of octagonal, hexagonal, pentagonal, circular, and other specific shapes.

The DPS can comprise a number of panels, for example, 6, 10, 12, 14, 20, 32, 36 panels.

The panels can be debossed with two parallel lines.

The panels can be at least partially stitched by a highly optimized stitching machine. The stitching machine can be equipped with an air pressure system.

The partially machine stitched ball is inverted inside-out so as to contain a specially developed rubber bladder in it.

The bladder can be selected from the group consisting of natural latex/rubber, synthetic latex/rubber including carbon-latex, butyl, and PU.

The bladder can additionally be wrapped with a fabric around it. The bladder can be a thread wound bladder.

Portions of panels within the ball, not stitched by a stitching machine, can be manually stitched to close the ball.

A special adhesive can be used to protect the seam gaps.

A ball that absorbs too much water will not roll very far if at all, and players will definitely notice it when they head the ball. The ball must stay afloat as much as possible and not sink like a stone. Under extreme conditions, when it has rained for hours and the ground is soaked, any ball will absorb some water. Thus, how much it absorbs is crucial.

In various embodiments, the water uptake by the present ball can be less than 0.4%.

A method of manufacturing a DPS sport ball can comprise sheet lamination, sheet sizing, printing of the panels, their debossing, cutting, die-punching, machine stitching, manual stitching and seam protection.

The sheet sizing can be done in accordance with the specific requirements of the shape and/or number of the panels by a highly specific laser guided presses.

The panels can be printed on the sheet by a highly optimized auto-printing machine.

A plurality of the panels can have a specific shape or size and printed in a single stroke. The printed panels can be debossed by a debossing machine. The printed panels can be debossed with two parallel lines.

A plurality of the panels can be cut out in a specific shape and size by a specifically developed cutting machine in a single stroke.

The multi-layered panels can be punched by computer numeric controlled (CNC) punching presses to form holes on both sides of the panels in one stroke in order to facilitate the manual stitching. The panels can be stitched together by a stitching machine. The stitching machine can contain a special air pressure system to press and control the panel while stitching. The machine-stitched panels can have a bonded bladder that is manually reversed.

The fourth and fifth lining layers can be bonded to the succeeding layers with a water-based natural adhesive so that each panel can comprise an outer casing material and five lining layers.

The ball is inverted manually and the bladder is incorporated in the partially machine stitched ball.

Remaining portions of the ball are manually stitched to close the ball.

The seam gap can be protected by a special adhesive manually applied or applied by auto-machine.

The ball can be optionally passed through a molding process to retain round shape of a ball.

These and other objects, features and advantages of the present invention will become more apparent upon reading the following specification in conjunction with the accompanying drawing figures.
