S [Previous technology] 5 pu material has been gradually applied to the outer surface of basketball in recent years due to its characteristics such as waterproof, abrasion resistance and softness, in order to increase the overall flexibility and financial properties of the basketball. The first picture shows a partial cross-sectional view of a blue ball with a PU surface layer. The process is first inflated inside a rubber bladder 10 layer 91 and borrowing a yarn winding machine (not shown) ) A winding layer 92 is formed on the surface of the inner tube layer 91 to maintain the overall shape stability of the inner tube layer 91. Then, a rubber victory layer 93 is cut into a plurality of sheets, which are attached to the surface of the winding layer 92, and then placed in a middle tire mold (not shown) to vulcanize to form a middle tire, and then on the surface of the middle tire. Pre-roughened 15 and glued. Then the shape of the rubber layer 93 was cut into multiple pieces and the edges were thinned. The PU layer was glued in 94 counties, and then it was completely manually attached to the surface of the corresponding rubber layer 93 piece by piece, and finally another one was placed. The tire mold (not shown) fixes its shape to obtain a finished basketball product. However, the above-mentioned steps of attaching the PU layer 94 cannot be further streamlined and shortened because the steps must be continued after the completion of the middle tire. In addition, since the ρυ layer 94 must be accurately attached to the corresponding surface of the arc surface of the rubber layer 93, it must be gradually applied by humans. Generally, the bonding time of each ball is about 20 minutes, so the labor time is extremely considerable.

At the same time as the above steps 11 to 15, as described in steps 16 and 17, 'provide a rubber layer 33 and a PU layer 34 (shown in the fifth figure) of appropriate size and all in a sheet shape, respectively. The material of the rubber layer 33 is Natural rubber is preferred, and the fibrous layer 34 has a thinner thickness than the PU leather required by conventional manufacturing methods. Then, as shown in steps 18 and 19, after combining the rubber layer 33 and the PU layer 34 ', they are cut into a plurality of panels 35 of an appropriate shape. One of the panels 35 is illustrated in the fifth figure. In this embodiment, the rubber layer 33 and the PU layer 34 are bonded with an adhesive such as rubber cement (jobber cement) 7 584566 玖, the description of the splashing light C4) '_ ^ such as mechanical compression, thermal fusion or any other suitable combination Also applicable. The size and shape of each panel 35 are not consistent, but all have an arc-shaped edge profile. Then, as shown in step 20, by applying an appropriate adhesive or other methods to the outer surface of the winding layer 32 and the inner surface of the rubber layer 33 of each panel 5 35, each of the town pieces 35 is bonded to the outer surface of the winding layer 32, and the sacral layer The material system is located in the outermost layer. As shown in the sixth figure, each panel 35 is adhered to the outer surface of the winding layer 32. All the panels 35 will generally cover the outer surface of the winding layer 32 together, and a random setting is formed between two adjacent panels 35. The groove 35 is stretched and bent as shown in the step 35. As shown in step 2: 1, the sphere 36 including the inner tube layer 31, the winding layer, the rubber layer 33, and the PU layer 34 is as shown in the seventh figure. It is shown that it is placed in a suitable mold 4 and heated and vulcanized. In this embodiment, the mold 4 is a conventional tire tyre mold, and includes two semi-spherical mold halves 41 and 42. When the $ 15 body 36 is placed on the lower mold half 41, the upper mold half 42 and the The half mold 41 2 is closed with a combination, and in a sulfurized, heated and pressurized environment for a predetermined time, the sphere 36 as a whole is fully vulcanized, so that the combination of the layers 31 to 34 is more tight and stable.
