Just wrap a ball in plastic paper

The process of making a soccer ball is as follows:

1. The cloth lining sticks to the leather.

Large pieces of synthetic leather have several layers of cloth on the back to enhance the strength of the material. The leather is fed into the press using a latex adhesive glued to the cloth lining. Less expensive balls are generally lined with two layers of cloth. Stronger, more expensive balls are generally lined with four layers of cloth.

2. Cut into pieces.

After the adhesive is completely dry, the large pieces of synthetic leather are fed into the die-cutting machine. The die-cutting machine cuts hexagonal pentagram panels of other shapes and punches out pinholes.

3. Embossed leather block.

Bring the cut pieces of leather from the previous volume to the screening area. Workers screen print the leather blocks separately, stamping them with the manufacturer's logo. This is done with a particularly quick-drying paint.

4. Make the inner liner.

The liner can be made of natural rubber or synthetic rubber. The raw material is slowly heated and pressed into the mold, where a balloon is formed. As the material cools, it wrinkles. Next, the worker removes the airbag and partially inflates it to smooth it out.

5. Stitching and final assembly.

Now you can assemble the ball. The leather block and liner are packaged in a tool for stitching. The sewing worker assembles the leather blocks in the correct order according to the illustration. The sewing worker finally sews the pieces of leather together by hand.

6 Sew the top piece of leather.

Insert the sewing needle into the gap between the inner liner and the leather block, and carefully sew the last seam.

7 The method of stitching is to ensure that each pentagon is surrounded by a hexagon, and that it is stitched on the reverse side.

8. At the end, leave one side without sewing, turn the football over from the left side, put the padding inside, and sew the last side together, and the football is ready.

Handmade football is handmade by the producer, stitched with leather, the football is round, anything is possible, the football field is changing rapidly, so we have to be careful, football is a team sport.

7. Sew 18 pieces into a new ball by hand. Generally, the football is composed of 32 pieces of pentagons, and this football is composed of 18 pieces, because the pieces are less, the splicing points and splicing lines are less, so the friction surface is less during the movement, the resistance is smaller, the flight trajectory is more stable and accurate, the shape of the ball is more round, the elasticity is higher, and the process requirements are higher. This type of ball has been used in the UK for almost a hundred years.

8. Closing is a technical work, and the fineness of the process has a great impact on product quality. In the process of closing the product, employees are given ample time to make every ball.
