The weapon tycoon who traveled to Daqin

Shang Wen came to the sewing workshop of the female worker. This workshop mainly produced the airbags of the airship. Now the airship needs to be re -transformed. Shang Wen cannot let them be idle. Let them make some clothes for the army stationed in the north.

The first sewing machine of the sewing machine is to make the birth of shoes. The original purpose of Shangwen is also for this. The airship needs a large number of pilots. These pilots need a large number of parachutes. Parachola requires paratroopers.

It is difficult for women to pierce the wooden board with their hands.

The sewing machine uses the legacy of the coil. The coil sewing method is very different from the ordinary handmade sewing. In the simplest manual sewing, the sewing person is tied to a line in the small eye on the tail of the needle, and then the needle connects the thread through two through two through two.

Wear the fabric from one side to the other, and then wear back the original side. In this way, the needle drives the lines in and out of the fabric, and sews them together.

Although this is very simple for handmade, it is extremely difficult to pull it with a machine. The machine needs to release the needle on the side of the fabric, and then grab it again on the other side.

The fabric, the direction of the rotation needle, and then repeat all the steps in the opposite direction. This process is too complicated to a simple machine and is not practical, and even if it is hand -to -hand, it is easy to use when it is shorter.

Then, then

On the contrary, the sewing machine only needs to pass the needle through the fabric. On the needle needle, the needle eye is behind the pointed, not at the end of the needle.

The needle is fixed on the needle rod. The needle rod is trapped through a series of gears and cam traction. When the tip of the needle passes through the fabric, it pulls a small coil on the other side.

This coil, then wrap it in another coil of another line or the same line. The principle is simple, but the current sewing machine can only make shoes, because this is the first, or a single -line chain hand -shaped sewing machine.

This kind of hand -shaped sewing machine can only be used to turn on the sewing machine, and the actual significance is not great. First of all, it is okay to make shoes, but the degree of strong. However, the female workers are very excited.

Shaking your arm, you can complete it yourself, and the performance is very excited.

The simplest coil suture is chain suture. If you want to sew out the chain suture, the sewing opportunity online uses a wire of the same length. The fabric is located on a metal plate under the needle.

At that time, the needle passes through the fabric to pull out a coil. One of the coils grab the coil before the needle is pulled out. The device is mounted with the needle. Once the fabric is pulled out, the fabric will be pulled forward.

When the needle passes through the fabric again, the new coil will directly pass through the middle of the previous coil. The device of the coil will grasp the wire again and make the coil around the next coil. In this way, each coil will fix the next coil in place in place.

Then, then

The main advantage of chain sewing is that it can be sewn very fast. However, it is not particularly strong. If the end of the line is loosened, the entire sewing may be loosened.

Sew.

The most important component of the locking device is the shuttle hook and the wire shaft component. The line shaft is a roll of wires under the fabric. It is located in the center of the shuttle. The latter rotates under the drive of the motor and synchronizes with the movement of the needle.

Same as the chain suture, the needle passes through the fabric to pull out a coil. While sending the fabric to move the fabric forward, it rises again, and then puts another coil.

Together, but connecting them with another section of the line from the line shaft.

When the needle puts the thread into the coil, the rotating shuttle shuttles grab the coil with a hook needle. With the rotation of the shuttle shuttle, it pulls the coil around the wire from the wire shaft. This makes the suture very strong.

This spin shuttle has also evolved through the shuttle.

The original reasons of the sewing machine's coil s stits evolved to the spin shuttle, and it entered the mature period.

But at present, this maturity period is far from reaching. The next improvement will be very exploratory.

"Who invented this kind of sewing machine?" Shang Wen asked. The word invention, some far -fetched. Because Shang Wen has provided three sewing machine drawings before, one is the current single -line chain sewing machine.

Hook's chain wire sewing machine. The last one is a mature lock sewing machine.

"I, I." A half -big child stood up.

"Oh." Shang Wen was interested at all of a sudden. The child looks like 14 or five years old.

"What's your name, how old this year is this year." Shang Wen asked.

"My name is Bai Ai. I am fifteen this year." Bai Ai said.

"Where are you?" Shang Wen asked.

"People from Qin Guo County." Bai Ai said. Shang Wen at the beginning of hearing Bai, he guessed that the child is likely to be Qin people. Because Bai is mostly surnamed in Qin Kingdom.

"Who else is there at home?" Shang Wen asked.

"There is another old mother. I got sick." It was said to have lowered her head. What does it mean to be sick and sick. It is estimated that it is a certain type of serious illness. The current medical and health situation is so bad, Shang Wen doesn't want to think about anything.

"Did you see the drawing of the sewing machine?" Shang Wen asked.

"Well, my master is watching. When I stepped forward to send food, I accidentally saw it." Bai Ai said.

This child only glanced at the principle, and it seemed quite talented. Shang Wen thought.

"Follow me in the future." Shang Wen patted Bai Ai's small shoulder.

"Also come with me, fill in the form of this technical patent. You get a technical invention. Get 20 gold rewards." Shang Wen said with a smile.

"Really." Bai Ai said happily.

"Really." Shang Wen said with a smile.

"However, I still have several sewing machines. If you can understand it all. And you can do it, then the rewards obtained by your technical patent will be very rich." Shang Wen said.

"Can I see it?" Bai Ai said eagerly.

"Yes, come with me." Shang Wen called.

"By the way. Give the ladies." Shang Wen's name was not suitable, but in order to reflect the respect of women. Shang Wen still used it.

"I have a proposal, that is, blending technology. Putting wool and hemp. Or a piece of silk and hemp mixing in one piece. So it is a brand new fabric. There are wool to keep warm and breathable. How about it? Try it.

Make a new fabric. Reward ten gold. "Shang Wen said with a smile.

"Ah, ten gold." The female worker suddenly exploded, and they never thought of it, so much money. The money was spent casually. This life is enough.

"Let's go." Shang Wen called Bai Ai. Then he turned and left.
