Embodiment Construction
[0034] In order to have a clearer understanding of the technical solutions, objectives and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.
[0035] The mechanized ball manufacturing method of the present invention can manufacture various types of balls, such as basketballs, volleyballs, footballs or rugby balls, etc., and is not limited to the types of balls exemplified in the following embodiments.
[0036] For clearly illustrating the method for the mechanization of the present invention, please refer to Figure 1A and 1B The step flow chart of this embodiment is illustrated with basketball as an example.
[0037] First, prepare an inner tube 10, such as Figure 1A As shown, a yarn layer 20 is formed by winding the yarn around the inner tire 10 to form a wound inner tire. The yarn layer 20 can form a protective layer similar to a cocoon to protect the inner tu...

Abstract
The invention discloses a method for mechanically manufacturing balls. The method includes preparing a winded inner bladder; coating a rubber carcass on the outside of the circumferential surface of the winded inner bladder; preparing a rubber carcass vulcanizing mold, and placing the rubber carcass into the rubber carcass vulcanizing mold to perform rubber carcass vulcanization treatment so thata vulcanized rubber carcass can be formed; preparing a cover vulcanizing mold, the inner wall face of the cover vulcanizing mold forming multiple raised strips, placing the multiple raised strips on the inner wall face of the cover vulcanizing mold, multiple leather pieces being in adjacent arrangement, and coating an adhesive agent on the faces, facing away from the cover vulcanizing mold, of theleather pieces, the material of the leather pieces being polyurethane; and placing the vulcanized rubber carcass into the cover vulcanizing mold to contact with the faces of the leather pieces coatedwith the adhesive agent, performing cover vulcanization treatment on the vulcanized rubber carcass and the leather pieces to make the multiple leather pieces vulcanized into a seamless skin layer which can be attached to the vulcanized rubber carcass, and forming multiple grooves corresponding to the raised strips of the cover vulcanizing mold on the leather layer so that a ball can be manufactured.
Description
technical field [0001] The invention relates to a method for manufacturing a ball, especially a method for mechanized manufacturing of a ball. Background technique [0002] Balls can be mainly divided into rubber balls and leather balls, which are classified and named after the outermost material. Generally speaking, the production process of a rubber ball is to paste a layer of artificial leather (such as polyurethane) on the surface of the rubber ball to make the ball have a better touch. [0003] In order to facilitate the description of the manufacturing process of traditional artificial leather balls, the following uses basketball as an example to illustrate, and please refer to Figure 3A and 3B shown. [0004] The traditional mechanized method of making a ball is to prepare an inner tube 90 first, such as Figure 3A As shown, the yarn is evenly wound on the inner tire 90, so that a yarn layer 91 is formed on the peripheral surface of the inner tire 90; then a middle...
