Winders are always expected to run full capacity especially the line installed only one winder. Capacity limit of winder directly connected to paper machine capacity. There could be many reasons that winder can not perform full capacity, such as vibration, winding quality, paper quality. Major cause is operation speed reduction or winding quality caused by vibration.
In conventional winders without special damping, vibrations can occur at higher production speeds for certain paper grades, and these vibrations can impair winding quality and production capacity. To minimize the disruptive effect of vibrations during the winding process, the production speed and accelerations rates are reduced below the maximum capability of the winder. Our solution is SmoothRun hydro-pneumatic damping bearings which can be effectively reduced the vibration even at high speeds. This mean winder can operate at high production speed constantly. At the same time, SmoothRun improves the winding results and reduces the overall mechanical stress on the machine.

In the past, one winder and one wrapping machine used to be arranged to process paper produced by one paper machine. In recent years, however, control of production data by computer has made great progress, and now we are in an environment where production data of wound rolls as finished products can be rapidly processed online.
Therefore, we have been able to develop a wrapping machine with a large processing capacity, that can automatically process various types of wound rolls produced by more than one paper machine to save labor, space and energy required by wrapping at a mill.
Our wrapping machine consists of equipment such as bar code reader, printer, wrapping machine, marking device and labelling device. Even a non skilled worker will be able to operate our wrapping machine in a short time because each equipment is reliable and can stand continuous operation for a long time, and also because of features such as complete interlocking and easy input setting, changing and monitoring by touch panel, based on our wide experience and achievements.
Through the use of our wrapping machine, complete wrapping of wound products can be performed.

In recent years, the technology for image processing has greatly improved. Digital cameras have become higher in resolution and speed, and computers are now capable of faster processing, enabling the development of new features in defect inspection systems. In this article, we will introduce some of the newly functions in SmartView inspection systems. Normally defect inspection systems only stored image data of the detected defects, but the newly developed streaming video can display, save, and replay the entire length and width of the roll. Using this streaming video data, a virtual inspection function has also been added for re-inspection of the roll. One of the new technologies is camera signal multiplexing, which generates multiple camera signals （video data） from one camera and allows separate multiple inspections to be performed in a single camera frame. The adaptive thresholding that follows background fluctuations and adjust the thresholds. SmartLearn classification combines automatic, learning classification. To use both functions SmartView system strongly supports detecting and classifying defects. Integration with external systems has also been enhanced, allowing SmartView systems to incorporate data from other systems and display that data on the SmartView screen, or transfer defect images and feature data acquired by SmartView to external systems.
Ametek intends to continue to support customers in building the most suitable inspection system for their manufacturing sites, leveraging the strengths of the defect inspection system manufacturer.

For efficient and effective pest management, the monitoring system （investigation using trapping tools such as light trap, wandering insect trap, and rat trap） plays an important role. Unless we establish the appropriate monitoring system, we can’t get accurate information about insects or rats intrusion or inhabitation, leading the customer’s complaints or the loss of products related to insects. On the other hand, there is also the possibility that excessive plan might lead to an increase the burden on the site. Therefore it is necessary to understand the importance and the role of the monitoring system in the whole managing system in order to select the right trapping tools or where to place them, based on the risk-based approach.
In this paper, several key points for monitoring systems to achieve efficient and effective pest management were mentioned. First of all, we have to understand the total structure of pest management （Pest management program）, including annual plans, organization, the way of communication, inspection/investigation, countermeasures, and training. Monitoring system is a part of pest management program, related to other elements. The meaning of “monitoring” is to analyze the sampling data and to utilize it for the root cause analysis, corrective and preventive actions, and verification, therefore we need to choose the suitable monitoring method based on the possible risks （characteristics of insects/rats and the importance of the zone in the factories）.
As for the selection of trapping tools toward flying insects, we have to select light trap model based on the properties of area and to make a decision for places of installation on the hypothesis that we suppose flying insects’ pathways of intrusion, considering not only the effectiveness to trap flying insects, but also the risk for attracting insects more than necessary. While, we select types of wandering insect trap and rat trap based on the characteristics of insects/rats or the environment around the place of installation （e.g. the floor which got wet）, and we install them on the places where wandering insects/rats can intrude or inhabit. In this manuscript, several risk-based viewpoints were provided. In addition, I introduce the latest rat-monitoring on-line system called “Pescle”, which we developed in partnership with Ryoden Trading Co., Ltd. We can only get accurate information using our original AI techniques for Pescle in order to formulate a sustainable pest-control systems.
Finally, several points to remember concerned with monitoring system, such as the interpretation of the monitoring data was provided here.

Recently, the improvement of digital technology has made it possible to accumulate large amounts of process data that had not been fully utilized.
With advances in technology of data accumulation, it is being especially important to handle big data. By using these data, it is possible to predict the occurrence of machine error or defects in products. Papermaking process is getting to be automated by application of such technology, but it still remains many controls that are set manually by operators. Therefore, it is a significant issue for paper industry to advance further digital transformation.
In this paper, we introduce our efforts focusing on foam on white water during the papermaking at the Kanazu mill, which is our DX model plant.
In our case, we had a problem of occurring defects by foam from white water and these defects had generated paper shorts. We had tried to solve this problem by utilizing big data accumulated in the Plant Information Management System. We had made a soft sensor consisting of extracted features with data analysis by Python programming and had been automated the addition of defoamer with a constructed soft sensor.
This effort enabled us to reduce occurring of defects and improvement of operational efficiency.

In papermaking processes, foam can cause a variety of problems everywhere. Foam problems not only hinder operation and productivity, but often have a negative impact on product quality, making foam control extremely important in solving problems in the papermaking process.
Since we started supplying papermaking chemicals to paper companies nationwide in 1948, we have been working together with our customers on foam control, and have developed a wide range of customized products for each customer process, and have become a chemical assistant for solving foam problems.
In recent years, the environment surrounding not only paper manufacturers but also chemical manufacturers has changed drastically due to a combination of factors such as a drastic disruption in the supply of raw materials caused by the global spread of the new coronavirus, soaring raw material prices due to inflation, and restrictions on raw material use due to various regulations aimed at environmental friendliness.
In this paper, we report on the latest trends in foam control measures that we have been working on in the midst of this rapid global situation.

In recent years, there has been an increasing trend toward more paper making defects and paper breakage problems in paper machines. Paper making conditions are becoming more severe due to the decline in the quality of pulp and recovered paper raw materials and the accumulation of contaminants caused by the closed paper machines. The focus of this study was on the fact that, based on the results of analysis of paper making defects and paper machine tool deposits, there are many cases in which slime involving microorganisms, adhesive pitch consisting of vinyl acetate, styrene, and acrylates mixed in from recovered paper, and anion trashes form a complex foreign matter. To improve the operation of paper machines, it is essential to reduce paper defects and breaks, and many paper machines have similar problems.
In terms of paper quality, the dosage of additives such as sizing agents and paper strength agents added tends to increase in order to improve and maintain quality, and in some cases, the fixation of these additives is poor. If these unsettled additives circulate and accumulate in the system, they can cause paper making defects and trouble with stains on the paper machine tools. To improve the operation of the paper machine, such as to reduce the number of paper breakages and defects, it is important to optimize the dosage of various additives without degrading the quality of the paper.
We have applied the slime control agent “CURECIDE Series” and the multifunctional coagulant “REALIZER A Series” to various fields such as paper machines, paperboard machines, and household paper machines, and conducted tests to improve the operability and paper quality of paper machines using the optimum addition method and optimum addition amount. The results of the tests will be presented.
