A sportsball includes a ball cover having a spherical ball cavity, an inflatable ball bladder disposed in the ball cavity of the ball cover; and a weight control arrangement which includes a plurality of weight panels. The weight panels are made of the same material of the ball bladder and are attached to the ball bladder for not only controlling a weight of the ball bladder but also strengthening the ball bladder to support the ball cover after the ball bladder is inflated.

A method of manufacturing a sports ball includes the steps of: providing a ball body having a valve stem formed thereat; providing a plurality of cover panels; integrally forming a plurality of sculptural bumps on at least a portion of one of the cover panels to form a sculptural ball surface of the cover panel; and overlapping the cover panels on said ball body to form a ball carcass in a stitch-less manner. Accordingly, the sculptural bumps are raised above an outer panel surface of the cover panel without applying a depression force to indent on the outer panel surface of the cover panel. The cover panels are interlocked and bonded with each other edge-to-edge to enclose the ball body inside the ball carcass.

A baseball, softball or the like includes a ball core and a plurality of carcass panels attaching on the outer surface of the ball core. Each of the carcass panels, which is cut into a predetermined shape, has a main portion and an edge portion formed along a peripheral edge of the main portion, wherein each of the carcass panels is attached on the outer surface of the ball core without stitching with other the carcass panels at a position that the carcass panels are attached in an edge-to-edge manner, such that the carcass panels form an outer shell at the ball core in a thread-less manner.

A sports ball includes an inflatable bladder, and a ball carcass. The ball pocket is constructed to have a true roundness shape, having an interior cavity receiving the inflatable bladder therein, wherein when the inflatable bladder is inflated, the ball pocket retains a true roundness shape of the inflatable bladder. The ball carcass includes a ball cushion and a plurality of carcass panels. Each of the carcass panels has a peripheral edge and a flat bottom surface defined within the peripheral edge, wherein the bottom surface of each of the carcass panels is entirely affixed to the ball cushion at a position that the peripheral edge of each of the carcass panels is fittingly aligned with the peripheral edges of the adjacent carcass panels to form a roundness carcass of the sportsball in a stitch-less manner.

A sewing rubber American football includes a rubber made ball cover having a valve hole thereon and a rubber bladder, which is disposed within the ball cover, having a predetermined shape and a valve stem mounted thereon and extended through the valve hole of the ball cover. The ball cover includes four elliptical cover pieces sewn edge to edge together. Each cover piece includes an outer elliptical rubber skin and an inner elliptical fabric pad integrally attached underneath the rubber skin. A top surface of the rubber skin provides a plurality of protruding pebbles evenly distributed all over the top surface. The rubber skin has a coarse bottom surface full of bumps and dents for gripping with the fiber of the fabric pad so as to firmly united with the fabric pad. Thereby, the rubber skin is reinforced by the fabric pad to form the tough and rigid cover piece which is able to be sewn easily. A ball cover made of such cover pieces is easily be grasped and thus has good slippery resistibility.

A method of manufacturing a stitchless sportsball includes the steps of: forming an integrated ball bladder; pre-making an integrated ball cover; cutting the integrated ball cover into a plurality of ball panels; and adhering the ball panels onto an outer spherical surface of the integrated ball bladder for encasing the integrated ball bladder within the integrated ball cover to form a sportsball and to form a plurality of ball channels on the sportsball. The integrated ball bladder includes an inflatable bladder encased in a reinforcing carcass in a stitch-less manner, wherein the inflatable bladder is vulcanized and integrally bonded with the reinforcing carcass for forming the integrated ball bladder in order to enhance a strength and roundness of the integrated ball bladder.

A sportsball and manufacturing method thereof are provided. The sportsball includes a carcass and a ball cover. The ball cover includes two or more cover panels having connecting sides connected with each other in edge to edge manner to form a plurality of connecting seams. The ball cover is supported and retained by the construction layer of the carcass in a desired roundness after air inflation. At least one the cover panels of the ball cover provides one or more virtual stitching seams molded to form thereon each imitating an actual stitching seam but having no stitching hole and gap. Each of the virtual stitching seams has a virtual seam recess and a plurality of virtual stitching marks along a bottom of the virtual seam recess imitating actual stitching marks of stitching thread like the actual stitching seam after sides of panels being sewn edge to edge together, so as to reduce the number of cover panels of the ball cover and minimize the presence of stitching holes and gaps of the ball cover.
