Embodiment 1
[0037] Embodiment 1, a sports ball with a flat seam, and a preparation method for a sports ball with a flat seam:
[0038] ⑴. Use the outer layer material (single-layer leather on the surface of the ball skin, or a combination of single-layer leather on the surface of the ball skin and a layer of base cloth) to form the raw material of the ball skin. According to the sewing requirements of the ball skin, the "outer layer material "The raw material of the ball leather is divided into leather blocks of the required shape;
[0039] ⑵. According to the sewing requirements of the ball skin, divide the step 1 to get the leather block with the outside facing inward, and sew it into a spherical shell with the inside facing outward and a flip opening (generally called "no seal");
[0040] ⑶. Composite at least one layer of inner layer material to the surface of the spherical shell with the inner surface facing outward obtained in step 2 (the outer surface during the composite operation...
Embodiment 2
[0045] Embodiment 2 is substantially the same as Embodiment 1, but its manufacturing steps are as follows:
[0046] ⑴. Using at least two layers of multi-layer composite materials as the raw material of the ball skin, according to the sewing requirements of the ball skin, make several leather blocks of the same shape or different shapes;
[0047] ⑵. According to the predetermined width, draw the stitching area around the edges of each leather block;
[0048] ⑶. Removing the inner material of the sutured area around the edge of each leather block, and only retaining the outer material;
[0049] ⑷. The outer surface of the leather block obtained in step ⑶ faces inward, and is sewn into a spherical shell with the inner surface facing outward and with a turning opening;
[0050] ⑸. Turn over the composite spherical shell obtained in step 4;
[0051] ⑹. Suture the overturned opening, and leave the bladder opening;
[0052] ⑺. The bladder is made of rubber or composite materials; t...

Abstract
Then invention discloses a playing ball with flat joints and a manufacture method thereof. An outer layer of the playing ball with the flat joints is ball cover made of leather in a sewed mode, an aerated ball container is arranged inside the ball cover, the ball cover is sewed by a plurality of leather blocks, and each of the leather blocks is formed by at least two layers of materials in a composite mode. The playing ball with flat joints is characterized in that sewing areas are arranged on the edges around each of the leather blocks, each of the sewing areas is made of the outer layer material of the ball cover and is single-layer leather on the surface of the ball cover, or each of the sewing areas is formed by single layer leather and a bottom cloth in a composite mode, the middle part of an area defined by the sewing areas on the edges around each of the leather blocks is a composite layer area, wherein at least one layer of inner layer material is arranged on the lower face of the outer layer material in a composite mode, and thus a multi-layer composite material is formed. The thickness of sewing ridges of the playing ball with the flat joints is obviously smaller than the thicknesses of sewing ridges of all kinds of playing bolls in the prior art, and thus the circularity of the playing ball with the flat joints is higher than the circularity of the all kinds of playing bolls in the prior art, and the uniformity of the elasticity of all different positions of the playing ball with the flat joints is higher than the uniformity of the elasticity of all different positions of the all kinds of playing bolls in the prior art. The manufacture method of the playing ball with the flat joints is simple and practicable in process, and easy to implement.
Description
technical field [0001] The invention relates to a ball product, in particular to a sports ball with flat joints. The invention also relates to a method of making the seamed flat sports ball. Background technique [0002] Sports balls, or balls, include footballs, basketballs, volleyballs, and other balls with similar structures. Its structure is that the outer layer is a ball skin (or outer skin, spherical shell or spherical surface, etc.) sewn by leather, and an inflatable ball liner is arranged inside the ball skin, and the ball liner is generally made of rubber. , and has an inflatable tube. The skins of modern sports balls are generally sewn from multiple pieces of leather (which can be called leather pieces, leather pieces or leather pieces); generally 12 pieces of pentagonal leather pieces, or 20 pieces of hexagonal leather pieces, or 18 pieces Sewn from rectangular leather panels. It can also be made by interlacing two or more leather sheets of different shapes. ...
