A4 Paper Machine
This is A4 Paper Making Machine,writing and printing paper making machine.
According to the different paper grade and working speed, this kind of paper machine is needed to select the way of papermaking, dewatering structure of press section, dryer cylinder bank, sizing and finishing equipments.
Sheet forming can use the open-type headbox, air-cushion headbox, and hydraulic headbox, gap former and inclined wire former. According to the paper uniformity requirement, it can use distributor roll or finishing surface roll.
Press dewatering type is multi-roll and multi-press nip press rather than large-diameter press. As the low basis weight and wet strength of this kind of paper, it usually makes the low strength wet sheet attached to the felt or guide rolls during each section mutual transferring and full web leading as much as possible.
Dryer section: dryer cylinder group. Paper leading: active or passive paper rope system. Finishing equipment: To choose according to the paper grade requirement.
Now we introduce the technical proposal and structural drawing of Fourdrinier advanced printing paper machine, which we made for Taiqian Minrui Huatong Paper Company in Henan province, China. The advanced printing paper of this company is the famous brand in China.

Working speed: 400m/min
Basis weight: 50-100g/sq.m.
Headbox: Air-cushion headbox
Forming table length: 15m
Suction flat box with all stainless steel micro-crystal cover.
Press section: four rolls two press nips
The wet sheet is stripped by pick-up suction unit.
The second under press nip rubber blind bottom roll diameter is Φ800mm, with drive unit;
The suction top roll diameter is Φ800mm, with drive unit.
The top press nip is made by a stone roll and a rubber roll. The rubber roll diameter isΦ800mm, with drive unit;
The stone roll diameter is Φ850mm, with cut squirt.
This structure ensures the low strength wet sheet can press smoothly and paper breaks can be reduced.
The smooth press rubber bottom roll diameter is Φ800mm; the top stone roll diameter isΦ850mm. The paper leading roll has the drive unit.
The dryer section has 32 dryer cylinders with the diameter of Φ1800mm, which is divided into five groups: three groups for before-sizing, two groups for after-sizing. The top and bottom felt of first group and the group at the back of sizing machine is equipped with six felt drying cylinder with the diameter of Φ1250mm, which can dry the moisture well and improve the drying efficiency.
The paper leading roll has the drive unit. The paper leading type is three-stage passive paper rope system.

Recently, at the 2014 International Tire Technology Forum held in Hangzhou, representatives from the tire industry at home and abroad conducted in-depth discussions on the current and future issues faced by the Chinese tire industry.
Recently, the United States Steel Workers Union of the United States on behalf of the United States to apply for the domestic industry tires "double anti-" survey, affecting the heart of the tire industry. The industry generally believes that the reason for this is that because Chinese tires have been exported to the United States too much, it has attracted the attention of domestic companies in the United States.
At the forum, John Y.Wu, director of the statistical project from the American Rubber Manufacturers Association, put forward his own opinions on the problems faced by current Chinese companies.
He said that the US market is actually an open market, but its competitiveness is also very strong. Through years of efforts, China's tire companies have successfully entered the US market. This is a relatively successful case. Further, It may be the success of a certain model.
However, he asked in reverse: "Do you want to continue this success? Or do you want to change it in other ways?"
The words of JohnY.Wu caused some thoughts of the participants. Chinese companies appear to be successful in entering the US market, but is this true success of Chinese tire companies? Or do Chinese tire companies successfully establish their own brand banner in the U.S. market?
According to analysis, this successful model is mainly based on "low-cost sales" strategy. In the United States, as long as consumers mention Chinese tires, they think of low-priced products. For a long time, this kind of impression has been deeply ingrained in the minds of consumers. The obvious thing is that without a brand, it is impossible for China to become a tire power.
Over the years, China’s tire production has been increasing year by year, especially semi-steel radial tires with cars as its main users. The output has grown rapidly. At present, the annual output has reached the number one in the world and it has become the largest tire country. However, in the international tire market, Chinese tire companies have not only increased their right to speak but have attracted one round of trade frictions.
So why are Chinese companies not raising R&D investment? Why not increase the added value of tire products and build your own tire brand?
In response to these problems, industry insiders explained that in order to increase the added value of tires, the company’s primary problem is to increase investment in R&D and increase research and development costs. However, as a result, the company’s operating costs and tire manufacturing costs also increase. The increase in the price of tires is the result. As tires are Chinese brands, they do not sell at high prices. Therefore, these two aspects seem to be in contradiction.
At the meeting, some people of insight believed that to increase the international brand image of China's tires, it was not so simple to raise prices and increase R&D investment. Breaking the bottleneck in the cost and R&D investment faced by companies in the development process was the key. The premise is that corporate decision makers must first establish brand awareness and have long-term plans for development.
Perhaps, as Secretary-General Xu Wenying of the China Rubber Industry Association stated at the meeting, this time the “double opposition†of the United States is not a good thing for China’s tire companies, but it may help companies to change the pattern of low-price exports. .
