Description

  The present invention relates to an improved structure of a baseball, and in particular, improves the moisture-proof elastic layer of the baseball, and quickly covers one moisture-proof elastic layer on the outer surface of the ball core to reduce the manufacturing cost. The present invention relates to an improved structure of a baseball that improves production efficiency and prevents the core from being dampened during the manufacturing process.

Referring to FIG. 1, a ball core 10 of a general baseball for an official game is formed by twisting a blended yarn or other spinning line layer. Since the blended wool yarn or other spinning line is rich in water absorption, in order to prevent the spherical core 10 from being deformed due to moisture and affecting its performance, after the spherical core 10 is manufactured, further moisture-proofing is applied to the outer surface. The elastic layer 20 is covered, and the outer layer 30 is further stitched to the outer surface of the moisture-proof elastic layer 20 to complete the ball. In order to adhere and fix the moisture-proof elastic layer 20 and the outer layer 30, a single spinning wire layer 40 is usually placed on the outer surface of the moisture-proof elastic layer 20, and an adhesive gel is applied on the spinning wire layer 40.

Currently, the moisture-proof elastic layer 20 (shown in FIG. 2) is mainly formed by heating and sulfiding the mold 50 using rubber as a raw material. Therefore, the molding of the moisture-proof elastic layer 20 requires a mold 50 and a molding tool, and purchase costs and maintenance costs of production facilities are also required. With rubber materials, it takes time to heat-sulfide molding the mold 50, and the production cost is reduced. To do. In particular, in the current production technology, the molding speed of the spherical core 10 is faster than the molding speed of the moisture-proof elastic layer 20, so there is a waiting time after the spherical core 10 is molded until the moisture-proof elastic layer 20 is molded. The spherical core 10 receives moisture during the waiting time.

The moisture-proof elastic cover has at least an opening, and the moisture-proof elastic cover is smaller than the spherical core before being provided on the outer surface of the spherical core.

The outer layer is the same as the ball core of a general official game ball, and is formed by stitching two pieces of eight-shaped sheet bodies to the outer surface of the moisture-proof elastic cover.

With the above-described element, after molding the spherical core, at least two moisture-proof elastic covers are bound to the outer surface of the spherical core in a corresponding direction to form a moisture-proof layer having elasticity. The two moisture-proof elastic covers that are tightly bound to the outer surface of the sphere core achieve the purpose of preventing moisture from the sphere core. A single moisture-proof elastic layer is quickly covered on the outer surface of the sphere core to reduce manufacturing costs, improve production efficiency, and prevent the sphere core from becoming wet during the manufacturing process.
