A PVC ball with a multi-layer structure, wherein the ball skin layer of the PVC ball is used as the outer ball skin, and the second PVC ball skin layer is used as the inner ball skin. The inner wall of the first PVC ball skin layer is fused with the outer wall of the second PVC ball skin layer; an air nozzle is inserted and connected to an inflation nozzle structure of the first PVC ball skin layer and the second PVC ball skin layer. The upper mold and the lower mold of the device are provided with closed mold fasteners for controlling opening and closing. One end of the rotation shaft is connected to the lower mold, the other end of the rotation shaft is rotatably connected to the mold frame, and one end of the revolution shaft is rotatably connected to the mold frame.

A recreational ball formed from a plurality of layers, a bladder and a valve. The plurality of layers is formed from a variety of different materials. Each of the materials that each of the plurality of layers is formed from is specifically oriented to create a ball that is durable, comfortable, and militates against air leaking from the bladder of the ball, as well as moisture seeping into the plurality of layers. The valve extends from a first layer of the plurality of layers, through the plurality of layers and is insertingly positioned within the bladder.

A gravity training ball includes a ball core unit having a predetermined weight specification, a buffer unit covering the ball core unit and made of a material having a shock absorbing effect, and an outer cover unit covering the buffer unit. The ball core unit includes an inner bladder defining a receiving space, and a filler received in the receiving space. The inner bladder has an inflation valve for inflation of air into the receiving space. The buffer unit has a thickness ranging from 2 mm to 30 mm. The ball core unit further includes an inner wrapped yarn layer disposed between the inner bladder and the buffer unit. The outer cover unit includes an outer cover layer covering the buffer unit.

A disco ball with an outer skin (3) which on the outside is fitted with mirror pieces (6) and has an expandable inner structure (2) comprising an inflatable inner skin which in expanded state is spherical and holds the outer skin (3) in a ball shape, characterized in that the outer skin (3) has a plurality of approximately lenticular segments (4) which are arranged next to each other, and adjacent lenticular segments (4) are releasably connected together to form the outer skin (3), and the lenticular segments (4) are each fitted with mirror pieces (6) on the outside.

Provided is a method for manufacturing an exercise ball which is made by using a pasted ball such as a soft leather ball and which has a lower impact value compared to a conventional yarn-wound ball. The exercise ball comprises a spherical hollow rubber bladder (2) in which compressed air is sealed, and a yarn-wound reinforcement layer (3) formed by evenly winding a filament yarn around the surface of the rubber bladder, wherein the exercise ball is characterized in that nylon filament yarn, obtained by hard twisting two 30-50 denier nylon filaments 1-a, 1-b in a single-direction twist is used as a winding yarn (1).

A game ball configured for organized, competitive play and having a total mass. The game ball includes an inflatable bladder, a layer of reinforcing material surrounding the bladder, an elastomeric layer surrounding the bladder, and a plurality of cover panels positioned over the layer of reinforcing material and the elastomeric layer. The bladder has a bladder mass that is greater than 25 percent of the total mass. The elastomeric layer and the layer of reinforcing material have a collective mass that is less than 55 percent of the total mass. The game ball is formed without one or more of electronics, batteries and charging coils.
