a skinned football

Abstract

The invention relates to a skin pasting rugby. A layer of foaming natural latex sleeve having the thickness of 0.2-0.3 mm is added to the surface layer of the inner tube, a layer or multiple layers of soaked or coated interwoven fabrics are pasted on the surface layer of the foaming natural latex sleeve as a skin pasting layer, and the interwoven fabrics are soaked in or coated by natural latex or a rubber-like material; several strips of base materials which are made of rubber materials or rubber foaming materials and have the width of 1.3-1.5 cm and the thickness of 0.8-1.3 mm and can cover the surface of the ball are pasted on the skin pasting layer, the base materials and the skin pasting layer are fixed through heating and pressurization, and a PVC, TPU, PU or real leather material is pasted on the surface layer of a semi-finished product after fixing is completed through heating and pressurization as the superficial layer.

Description

technical field [0001] The invention relates to a rugby structure and a preparation method prepared by a skinning or sewing production process. Background technique [0002] Existing pre-skin rugby (including rubber middle tire skin), all are to wrap one or more layers of wires on the surface of the inner tube, then paste the rubber layer on the surface of the line, heat and shape the mold, and then paste a layer of PVC on the surface. , or PU and leather production process, the structural characteristics of this process are: the surface layer of the inner tube is cross-wound on the surface layer by specific equipment to form an inflated and shaped strength layer, and then a layer of rubber is pasted on the surface of the winding line. After warm molding, make the surface smooth and increase the strength, and then paste PVC or PU, leather materials on the rubber surface. [0003] After the finished product produced by the above process structure is inflated to the required ...

AI Technical Summary

Problems solved by technology

[0003] After the finished product produced by the above process structure is inflated to the required air pressure, the ball is hard as a whole, and the athlete has a poor sense of control over the ball. Because the hardness of the ball is too hard, it is easy to cause injury to the athlete.

In addition, the finished products produced by the existing process structure have poor appearance and dimensional stability, poor consistency in mass production, and insufficient quality stability, which have a greater impact on the brand image.
