Football is a sport in which two teams of 11 players go up against each other with the objective to get the spherical ball into the opposing team’s goal which is at their end of the rectangular field. In the sport football only Goalkeepers are allowed to use their hands and outfield players will only use their feet to pass, shoot and dribble the ball.
The game is won by the team that is able to score the most goals over the course of the 90 minute match, depending on the format of the competition if the game finishes a draw, it may go to extra time and if the result remains a draw it will be followed by penalties.
A regular soccer ball will be made of synthetic leather, most commonly polyvinyl chloride or polyurethane, which will then be stitched around a piece of rubber that makes up the ball’s bladder.
All modern balls have an inflation valve in comparison to older balls that were made of genuine leather and held shut with cotton laces.
The leather panels are than covered with cloth that is usually made of polyester and is sometimes a poly cotton blend.
The size requirements for standard play are: it must be
- no bigger than 28 in (71.12 cm) around, and
- no smaller than 27 in (68.6 cm).
- It must weigh 14 ounces minimum and 16 ounces as the maximum.
- It must also be filled to have air pressure of 15 lb per square in (6.8 kg per square cm).
The Process of Making
To make a football you will need to make two elements of the ball which include inner bladder which is made of rubber and the outer covering which is composed of leather and cloth.
- Synthetic Leather sheets are backed by multiple layers of cloth, which serves the purpose of strengthening the material. The sheets are then sent through a machine that a latex adhesive and this binds the cloth. Depending on the quality of the ball the number of cloths may vary, from two for a cheaper ball to 4 for a more expensive, better quality ball.
- Once the latex adhesive is completely dry, the sheets of leather are then passed through a “die cutting machine” and workers will load the cloth into the die cutter which then cuts the generic hexagonal panels into the ball and also punches and stiches the holes.
- At this point if the ball is being manufactured by a brand e.g. Nike or Adidas the ball is then taken to have the logo imprinted with the use of a special fast drying paint.
- Next you can begin to make the bladder, this is made by heating the rubber which is most commonly natural or synthetic so it is effectively forced into a mould in which it forms a balloon. Once the material cools down, it will begin to wrinkle. Once this happens the workers will remove the bladder and give it some partial inflation to smooth it out.
- Now the ball can actually be assembled, the panels and the bladder are packed in a kit in preparation for the person that will stitch the ball; the panels are then stitched together by hand.
- Once the cover is sewn, the bladder is inserted; at this point the ball is complete. Most commonly for assurance that the bladder was not punctured by a needle whilst being stitched, it is then inflated as a test. At this point it will probably be measured and weighed before it is deflated again in preparation for shipping.
