Abstract

The invention discloses a rugby football which comprises a ball bladder, a composite reinforcement lining and a surface layer, wherein the composite reinforcement lining comprises a fabric layer and at least one layer of reinforcement lining; uniformly distributed recessed air grooves or air layers are arranged on one surface of the reinforcement lining; the surfaces of the air grooves or the air layers are made of foaming or rubber soft materials; the reverse surface of the reinforcement lining is made from synthetic materials; the total area of the uniformly distributed recessed air grooves or air layers is 18-65%; and the cross sections of the air grooves or the air layers are U-shaped, C-shaped, rectangular or rounded rectangular. The reinforcement linings with various air cushion structures are sewn to make rugby footballs with various specifications and grades, the process is more scientific and reasonable, the function is more excellent, the ball body structure meets the strength requirement and can become soft, and the rugby football can be well controlled by a footballer.

Description

technical field [0001] The present invention relates to the structure of a rugby ball prepared by sewing. Background technique [0002] The production process of rugby (including hand sewing and car sewing) in the existing sewing method is to paste one or more layers under the skin material (the skin material includes: rubber, PVC, PU, ​​or different levels of leather). Full-plane auxiliary materials, the auxiliary materials pasted below, are generally called reinforcing lining in the industry. The main function of this reinforcing lining is to achieve the corresponding effect of the sphere due to the fact that the sphere must be filled with gas in various sports or competitions. Various specifications and shapes, so that the function of the sphere in motion can be realized and brought into play. Because if you don’t add a reinforced lining ball, generally inflated to the air pressure range specified by the ball type, the ball will be deformed or the suture will break durin...

AI Technical Summary

Problems solved by technology

[0012] After adding the surface reinforced lining, we can sew various rugby balls with different structures. Although the strength and specifications of the sphere can meet the requirements after inflation, the overall hardness of the sphere will be harder. This is a common phenomenon. Rugby made of rubber lining is still hard; a hard or too hard ball will easily cause impact damage to the contact parts of the athlete's body during flight or hitting, and it will also make the athlete's control over the ball greatly weakened
