How the ball is sealed, how to sew the last stitch 20

But it's usually hand-sewn! So there's only one answer. With a needle and thread!!Landlord, the problem of 20 years of confusion has been solved, right?

I know, because I've sewed a soccer ball before, first sew the piece and piece together, and when it's time to seal it, leave the thread of the sewing ball inside, and it's okay!

Balls like logbooks are pressed and pressed together by machines from several directions.

You don't need to sew, the machine will sew

There is a little man in it, the last seam he sewed in it, I thought about it for 25 years to come up with, I don't believe you hold the football and shout: Hello! She'll be:

How are you, your voice is very tender!! Hehehehehehehehe! Still a girl!!

Give it a try!!

Haha, I don't always get it.

Is the valve so small?

Actually, I know it's an air mouth, but I just want to be different.

How can you do it at such a small size?

The junction of any corner can be the last stitch.

There is a special machine that sticks in when the valve is not installed.

Now soccer balls are glued with high-tech and do not use needle stitching

Haha, I've been thinking about this question for a long time, haha, I don't understand.

It's basically difficult!

You can continue to think about it for another 20 years, the old man has been thinking about it for more than 80 years.

The outer layer is a layer of cowhide, and then a layer of cotton cloth is attached to the rubber bladder. However, there is already a new material to replace cowhide.

The production process is as follows: 1 cutting 2 cutting 3 sewing 4 weighing 5 stitching 6 gluing 7 veneer 8 adjusting air pressure.

FIFA International Football Match Balls:

In the early days of football, there was no restriction on the size of the ball, as long as it was spherical. It was not until the 70s of the 19th century that the circumference of the sphere should be between 69 and 74 cm.

The World Cup special ball is designated by the German company Adidas to provide the design, the 2002 World Cup and the 2006 World Cup special ball are Chinese translated into the Fevernova and Team Star (+teamgeist, English for team spirit, interpreting team spirit).

Machine sewn, not clear.

I've always been curious about this question.

Just like Rentang, by going back to a confused person and others agrees to communicate with him well with different individuals

Help with a variety of tools.

From the inside seam, the last one is left, and when the last one is turned back.

Then sew it from the outside, finally repair the thread, and then stuff it into the inside.

The professional sewing method is to use double threads and double edges, turn the football over when sewing the remaining six or seven sides, and then sew it with a complex needle method that does not show the thread outside, every three pieces of leather have an intersection, and finally the needle and thread are threaded into the leather from the intersection point of the needle, and then from another adjacent intersection point (be careful not to puncture the ball gall), tighten (do not leave a line in the middle of the ball), tie a knot (to tie it very tightly), and then pinch it, let the knot bounce into the ball from the last place where it is threaded, it will be blocked in the ball by the intersection point when the needle is closed, Invisible from the outside

The last few stitches are picked. The last needle is tied in a knot and then threaded into the needle.

It's a real high tech!

In the early years, when Adidas processed the football in Pakistan, it was completely hand-sewn, and it is said that the 32 pieces of football (10 white and 22 black) were not sewn one piece and then sewn the next piece, but first strung together the 32 pieces of skin according to the position, and then tightened the thread, tightened the ball skin, and finally tied a knot in a very hidden place and called it a day!

Older golfers should still remember that the so-called famous football "locomotive" in our country often broke a small hole and puffed up a piece of kicking, and finally only exploded ......The only reason - the technology is not good, it is not sewn well.

Today's soccer balls are made of PU material and thermal bonding technology, so there is no need for sewing.

Now that there are artificial eggs, how do you get them? I don't know.

First, sew the ball skin on the opposite side, but leave a hexagonal piece without seams (it seems to be the ball where the air hole is located), then turn it inside and out, and stuff the uninflated ball into it (the air hole of the ball bladder has fixed the last piece of ball skin), and then sew the last ball skin on; There is also a possibility that the ball skin that is wider than the ordinary ball skin is surrounded by good glue, adjust the position to cheer up, so that the ball skin and the ball gall bladder are swollen and matched, and wait for the glue to solidify; Finally, the modified skin on the surface is glued to the finished product.

There are two kinds of football, one is inexpensive and is pressed with gum at one time. Only the other one of better quality is the last piece of skin that is sewn together. This kind of football is divided into two parts, one part is the outer skin, and the other part is the inner core (i.e. the airbag) The outer skin is first sutured and then turned over, and in this process, space will be reserved on a certain piece of skin, and this reserved space is the place where the airbag is stuffed, and further sutures will be carried out after the airbag is inserted, leaving only the inflatable valve part.

The last piece is glued, and good soccer balls are not stitched, they are all glued, generally made of 12 pieces of black pentagon fabric and 20 pieces of hexagonal fabric.

What's wrong with your grandmother, you can just go to the factory that makes soccer balls.

There was a thing hiding in the sewing, and it disappeared automatically after the sewing was done.

You don't care how he sews it. I don't want you to sew.

As soon as the assembly line came out, it was already good.

I know! Our field is the production of football! Contact **0728 2694110
