Inflation adhesive ball fabric-liner middle tread and manufacturing method thereof

Abstract

An inflation adhesive ball fabric-liner middle tread and a manufacturing method thereof relate to an inflation ball. The invention provides a fabric-liner middle tread capable of remarkably improving the bouncing performance, dynamic stability and beating feeling of a ball, easier for controlling the ball and used for producing an inflation adhesive ball and a manufacturing method thereof. The inflation adhesive ball fabric-liner middle tread is provided with a liner, wrapping cloth and surface leather; the wrapping cloth is provided with at least 12 sheets, the 12 sheets are classified into warp sheets, weft sheets and oblique sheets according to the adhesion direction, at least four warp sheets are symmetrically arranged on a warp, at least four weft sheets are symmetric arranged on a weft, at least four oblique sheets are arranged between the warp sheets and the weft sheets, each sheet faces towards the spherical center and is wrapped on the liner through adhesive, and the liner, the wrapping cloth and the surface leather are integrated in a fusion way. The liner is inflated, after the air tightness test, the liner is placed into a standard template, and the liner is inflated to the diameter limited by the standard template; the cloth sheets are cut; glue-water is pasted on the surface of the inflation liner; the well-cut cloth sheets are coated with glue-water; and the cloth sheets are adhered onto the liner to form the middle tread.

Description

technical field [0001] The invention relates to an inflatable ball, in particular to an inflated adhesive ball cloth inner tire and a manufacturing method thereof. Background technique [0002] Adhesive inflatable balls (such as basketball, football, volleyball, rugby, etc.) are generally equipped with an inner bladder, a middle tire, an outer shell, and an air nozzle from the inside to the outside. The middle tire is located between the inner tank and the outer shell, and the middle tire plays the role of control, support and transition. The performance of the middle tire plays an important role in determining the overall performance of the ball. [0003] The middle tire of the existing adhesive inflatable ball is generally formed by wrapping yarn on the surface of the rubber liner. Such a yarn-wrapped middle tire has the following disadvantages: the slapping feel is relatively hard, and the bounce height has certain limitations (generally only 51 to 54 inches). , the beat...

[0003] The middle tire of the existing adhesive inflatable ball is generally formed by wrapping yarn on the surface of the rubber liner. Such a yarn-wrapped middle tire has the following disadvantages: the slapping feel is relatively hard, and the bounce height has certain limitations (generally only 51 to 54 inches). , the slapping sound is heavy, the dynamic stability of the ball is insufficient, and it is difficult for players to control the ball
