What is the principle of seamless technology in football production?

It is getting closer and closer to build the "team star" of the 2006 World Cup in Germany with special-shaped blocks and seamless splicing technology. Although China missed the World Cup, the Super League players have already felt the charm of the World Cup "team star" in advance in training. This game ball, which has been newly designed and developed for three years, is called the best football in the world so far. Is there any good way? Let's go and have a look. Since the official appearance of Team Star at the end of last year, players and the media have almost praised it. In addition to the beautiful appearance, the most evaluation is "comfortable with the ball." So what's unique about this football? From the appearance, the "team star" is mainly composed of three colors: black, white and gold. Black and white are the traditional colors of the German national football team, the host of this year's World Cup. Gold represents the World Cup trophy. "Team Star" is the first football made by fully embedded printing technology, thus ensuring the durability of the ball's appearance pattern. Different from the previous football surface consisting of 32 skins, "Team Star" adopts brand-new irregular blocks and seamless pressing technology, which reduces the number of football spherical blocks to 14 as never before, eliminates the irregular protrusions on the ball surface to the greatest extent, makes the ball smoother and presents a more perfect arc, thus effectively improving the stability and accuracy of football operation and reducing the mistakes in football flight. The outer layer of "Team Star" continues the new composite foam developed by Bayer Company in Germany. There are many micropores with the same size in the foam layer of this structure, which has the characteristics of super compression resistance, so that the football can quickly recover its original shape, thus having excellent elasticity. A new type of mesh cloth is specially prepared under the foam layer to improve the strength of football and make it difficult to deviate when flying in the air. As the ball for the 2006 World Cup in Germany, "Team Star" has undergone a series of rigorous tests jointly conducted by the Adidas Innovation Team and the Sports Technology Research Center of Loughborough University. No matter in weight test, rebound test, ball pressure test, impact test and water absorption test, the performance of "team star" far exceeds the qualification standard set by FIFA. Finally, it is worth mentioning that Adidas named the newly designed match ball "Team Star", which means that the strength of the team is very important to win the World Cup. As the biggest football match in the world, the stars shine in the World Cup. However, even the best players must work closely with their teammates and rely on the strength of the team to win the final victory. The R&D staff of "Team Star" hope that the crystallization of their collective wisdom will make the athletes on the court know more about the value of team spirit.
