Description
Technical field
The present invention relates to a kind of hollow ball, particularly to a kind of hollow ball, manufacture method and use this sky
The sport ball of bulbus cordis body.
Background technology
The molding mode of the hollow sport ball such as basketball is first to make inner bag, is then wrapped with yarn on inner bag,
Then it is placed in the spherical shell (being also middle tire) of sewing or other mode molding.Its structure generally includes:
Inner bag, i.e. bladders, in the inside of ball, generally use black rubber, butyl rubber to make；Twine yarn, inner bag
Surface uniform winding yarn blend compounds water logging is coated with yarn, and inner bag is formed the protective layer as Bombyx bombycis, or
Laminating gauze on inner bag surface replaces winding yarn, in order to ensure the circularity after inflating；Spherical shell, inner bag and table
Supporting construction between skin, is made up of elastomeric material；Covering, be divided into rubber, synthesis skin (superfine fibre,
PU, PVC etc.), corium three major types；Ball mouth: be connected to the passage of the inflation of inner bag, air-tightness is the most crucial.
Wherein twine yarn and commonly use gauze replacement, fit with a gauze on inner bag surface, fit the tightest, protection
Effect is the best.Owing to gauze softness is yielding, need to be arched upward the most about by smooth gauze in advance before laminating
Bundle to operate, such as makes it substantially be constrained to ball with yarn gathering of tying the edge of gauze for sphere
Face.And gauze also has certain ductility, therefore after laminating, the position, edge of gauze is the most wrinkling gets loose.
Further, since during inner bag, use black rubber, so there is problem of environmental pollution, even if adopting when producing
Can not avoid completely with butyl rubber.And the necessary winding yarn in inner bag surface, otherwise inner bag cannot bear
Air pressure deformation after inflation, causes spheroid to play drum and loses circle and cannot use.
Summary of the invention
In order to overcome the deficiencies in the prior art, first purpose of the present invention is to provide a kind of hollow ball,
It has materials environmental protection, simple in construction, molding is fast, circularity good and intensity is high feature.
