Embodiment 1

[0076] Such as figure 1 As shown, the present embodiment provides a foamed middle tire, including an inner container 1, an anti-inner container deformation layer 2 and a foam layer 3, the anti-inner container deformation layer 2 is wrapped on the outer surface of the inner container 1, and the foam layer 3 covers It is arranged on the outer surface of the anti-deformation layer 2 of the liner.

[0077] As a preferred embodiment, the anti-deformation layer 2 of the liner adopts a yarn layer or a first patch layer. The yarn layer or the first patch layer is arranged on the outer surface of the inner tank, which can fix the circumference of the inner tank, prevent the inner tank from expanding infinitely during the inflation process, and prevent the inner tank from being deformed. However, the material of the anti-deformation layer of the liner is not limited to yarn or patch, and other fabric layers that prevent the deformation of the liner also belong to the scope of protectio...

Embodiment 2

[0083] The difference between this embodiment and embodiment 1 is that the inner tank deformation prevention layer 2 is a composite layer composed of a yarn layer and paste or latex, or a composite layer composed of the first patch layer and paste or latex.

[0084] Further paste or latex on the outer surface of the yarn layer, the first patch layer or other fabric layers, the paste or latex can make the yarn layer, the first patch layer or other fabric layers more compact after drying and solidification, Strong, can better prevent the deformation of the liner.

[0085] Similarly, the anti-deformation layer 2 of the inner tank in this embodiment is not limited to the yarn layer or patching layer, and other composite layers composed of fabric layers and paste or rubber that prevent inner tank deformation also fall within the scope of protection of this solution.

[0086] The foamed middle tire provided by the present embodiment is made by the following method:

[0087] (1) A l...

Embodiment 3

[0096] The difference between this embodiment and Embodiment 1 is that a middle tire for basketball or rugby is provided, and the outer surface of the foam layer 3 is pasted with stem lines. As a preferred embodiment, the material of the stem line is selected from synthetic materials such as PVC, PU, ​​and fiber materials according to actual needs.

Abstract

The invention discloses a foamed middle tube, a leather stuck ball and a manufacturing method. The foamed middle tube comprises a liner, a liner deformation preventing layer and a foam layer, whereinliner deformation preventing layer is coated on the outer surface of the liner; and the foam layer is coated on the outer surface of the liner deformation preventing layer. According to the foamed middle tube, the foam layer is directly stuck to the liner deformation preventing layer, so that based on the characteristic that the foam layer is light in weight, the weight of the liner can be increased by using the middle tube with the same weight, and the thickness of the liner made from the same material can be increased, so that the airtightness of the liner is improved; the foamed middle tubecan be applied to a volleyball with the relatively light weight, and also can meet the requirement of the liner with a complex structure; in addition, the ball has better bounce and flexibility without the constraint of a middle rubber layer; meanwhile, the original flexibility of yarns or patches and foam can be kept, the sense of flapping touch is softer and more comfortable; the foamed rubbermiddle tube layer is replaced with the foam layer, a vulcanization technology and a polishing process during a manufacturing process can be avoided, and bad and nonuniform foaming during a vulcanization process also can be avoided.

Description

technical field [0001] The invention relates to the field of ball products, in particular to a foamed middle tire, a leather-coated ball and a manufacturing method thereof, in particular to a foaming middle tire, a leather-coated ball and a manufacturing method free from vulcanization and grinding. [0002] technical background [0003] With the development of the economy and society and the awakening of the health awareness of the whole people, the number of people participating in physical exercise in our country is increasing day by day. As a large category of sports, ball games are increasingly favored by people, including basketball, football, volleyball, rugby And so on, especially basketball and football are becoming more and more popular in the sports of school students, and corresponding teaching courses have been set up. In order to improve the user's experience and give full play to the technical level of athletes, various new ball products have also appeared. [...
