What's the matter with the scratches on the inside of the big edge of the folding fan?

Today, let's talk about a mysterious thing. You must have seen several mysterious knife marks on the inside of the big bone of the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan, but many people can't tell what it is. A novice player asked me before, and I was also asked, and I fumbling and fooling around.

These traces are not moth-eaten or flaws, but marks specially made by the fan maker when he made the fan. However, what is the purpose of this mark? Why do some masters do it and some masters do not? Some masters do it covertly, and some masters do it obviously?

Many people have noticed this mark, and there is even a saying that those with this mark are hand-made fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fans, and those without this mark are made by machines. This rumor directly pokes the pain points of novice players, and it is also a clamor for a while. Many masters have received calls to ask, "There are no scratches in my fan, did I buy a machine fan?"

Here, the editor first refutes this rumor, which is very wrong and hurts a lot. Whether there is this mark or not has nothing to do with manual work or not.

This mark is the unique work habit of the masters who came out of the fan factory. Regarding the question of this trace, I also tentatively asked some friends who like fans a long time ago. Most of them are vague and guesswork.

This kind of mark first appeared in the hand-made fan bone making process of Su fan, so it is also called "Suzhou Code", and it is also called "Suzhou Ji". In the 1990s, Suzhou masters went to Anji to teach skills to help the local development. The crafts of the two places are in the same line, so the fans produced by Anji also have this mark, and they are called "playing numbers" in Anji.

Function 1: It is to distinguish the positive and negative sides of large aggregates.

Many friends may be wondering - the front and back of bamboo are not well distinguished, why do you need to make a mark? First of all, our players think that the front and back of bamboo are very easy to distinguish because what we see is the finished product. After polishing, the degree of distinction between the front and back of the raw material is not so high. Secondly, in the past, the masters of the fan factory used several sets to start work together, and there were requirements for speed, so marking them in advance was the most efficient and least error-prone way. Finally, many fan factories not only make bamboo fans, but also wooden fans. It is necessary for wooden fans to make such a mark to distinguish the front and back.

Function 2: Marking the pairing of two large bones.

You must know that even if it is Yuzhu, the two large bones must be matched in advance. Even though they all look the same, the color and the density of the bamboo threads are very different. At the end of the last century or even earlier, the masters who worked in the fan factory at that time all had production requirements, and more fans had to be started at the same time, and at most five fans could be made together. The 5 pairs of big bones are 10 pieces of bamboo, arranged in a row, and the matching must be marked, otherwise it is very likely to make a wrong pairing later. If you don't make a mark, check the pairing every time to ensure that there is no mistake, which will seriously affect the work efficiency of the factory.

Therefore, the most simple and direct method is to make a few marks after the large bone blanks are matched. The "one bar" corresponds to the "one bar", the "two bars" corresponds to the "two bars", and so on. , one-to-one correspondence. Faced with the above explanation, we must still have problems. Why do we usually only see the marks of knife scratches on one side of the big bone?

Because now the masters have become independent artists, the production process of the big bones of the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan has slowed down and the quality has improved. Now, one is finished and the next one is made. It is not like before. There is no need to make a pairing mark, or distinguish the marks on the front and back.

Then there are questions! Since it is done one by one, then the marks are not necessary at all, so why mark one of the big bones? At this time, it is time to talk about the third function of this trace.

Function 3: Record the order in which the large bones on both sides correspond to the small bones.

The single green bamboo small bones are all green on one side and spring on the other. The green is positive and the spring is negative. When arranging the small bones, it is like a line of people, everyone faces one direction. The mark on the big bone tells the fan maker which big bone the front (or back) of the small bone faces. That is to say, the mark is left for the convenience of assembly.

Then the question comes again, can it be that the small bones cannot be assembled after turning around as a whole?

It can't be said that it cannot be assembled, but it is not as good as the assembly according to the mark. Because of the difference between a manual fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan and a mechanism fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan, the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan needs to be made by hand, and the tools for making the fan.com/Products/Foldingfan/ target=_blank class=infotextkey>Folding fan are not high-precision CNC machine tools, and cannot be 100% symmetrical, so the error between the accessories cannot be ignored. It may not be so flat. So what's the best way? It must be which big bone the small bone faces when doing it, and that side when installing it!

That being said, even machine semi-manual fans need to be imprinted for final assembly. So again, this mark has nothing to do with whether it is made by hand or machine.

So why are there no marks on the fans of some masters at all? Many young masters have never worked in a fan factory or made fans in batches. From the day they learned to make fans, they have been making them by hand, so they can actually remember which way they are facing without making a mark. Or they made the marks light and sanded them off at the end. It's that simple.

In addition, there is an additional function - it is combined with the seal to form an anti-counterfeiting mark. Of course, only the fan maker knows the identification method.
