Description
Technical field
The utility model relates to a kind of hollow ball, particularly to a kind of hollow ball and the motion using this hollow ball
Ball.
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 will
It is placed in sewing or the spherical shell (being also middle tire) that is molded of other modes is interior.Its structure generally includes: inner bag, i.e. bladders, at ball
The inside, generally uses black rubber, butyl rubber to make；Twining yarn, the uniform winding yarn blend compounds water logging of inner bag surface applies yarn
Line, forms the protective layer as silk cocoon to inner bag, or the laminating gauze on inner bag surface replaces winding yarn, in order to ensure to fill
Circularity after gas；Spherical shell, the supporting construction between inner bag and epidermis, it is made up of elastomeric material；Covering, is 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 very crucial.
Wherein twining yarn and commonly using gauze replacement, fitted by a gauze on inner bag surface, fit tighter, protected effect is got over
Good.Owing to gauze softness is yielding, needing before laminating arches upward smooth gauze in advance is substantially constrained to sphere to operate,
Such as it is made substantially to be constrained to sphere with the gathering that carries out tying of the edge to gauze for the yarn.And gauze also has certain extension
Property, after therefore fitting, the position, edge of gauze is easily wrinkling gets loose.
Further, since during inner bag, use black rubber, so there is problem of environmental pollution when producing, even with butyl rubber
Glue can not be avoided completely.And the necessary winding yarn in inner bag surface, otherwise inner bag cannot bear air pressure deformation after inflation, causes
Spheroid plays drum and loses circle and cannot use.
