Introduction of the MFC/MF ScreenNaoyuki Iwashige1997 Volume 51 Issue 1 Pages 31-39

Released on J-STAGE: November 19, 2009
JOURNAL FREE ACCESSIn the conventional secondary fiber system, the reject rate must be larger to keep the screening efficency better, and the fiber bundles in the reject stock must be also deflaked to maintain the yield higher.
In consequence, the screen system, particularly the reject line, will go to larger and more complicated scale, and it will result in various trouble of the screen system.
The MFC/MF Screen, developed by Ishikawajima Industrial Machinery Co., is the revolutionary device which can enormously reduce the reject rate and extensively simplifies the conventional screen system, while keeping the screening efficiency of the accept stock. The MFC/MF Screen can reduce both initial and running cost by about 50 percent compared with the conventional screen system.View full abstractDownload PDF (2699K) -

JOURNAL FREE ACCESSDouble Coating is getting popular in production of wood free coated paper grades. This is the world trend. Japanese trend in coated paper production is not free from the world trend. There are several reasons to install new duble coating systems or to replace conventional single coating systems with modern double coating ones. What are the advantages of double coating, paper quality or economy ? Our answer is straightforward, “Both”. Paper quality and the production cost have to be optimized. Double coating gives us flexibility to optimize the paper quality, the production cost, and runnability, as well. No.2 Coater as Ishinomaki Mill was rebuilt from a single coating blade coater to a double coating blade coater in 1992. In this paper, we describe the fundamental concept for No.2 coater's double coating and the experiences at the mill.View full abstractDownload PDF (1885K) -

JOURNAL FREE ACCESSToday many of the paper manufactures producing coated grades are interested in cross direction coat weight control. Recenthy, Measurex has introduced new technologies for this control. An infrared coat weight sensor measures the coat weight directly with a light profile filter. ProCoat is the intelligent coat weight profile control actuator with LAN-based communication. These features provide optimized results of the cross direction coat weight control. In addition, drying rate control calculates the “Gelpoint” and optimizes each drying device output to maintain the coat surface quality with minimum energy consumption. In this paper, we introduce the successful results of the ProCoat actuator and the infrared coat weight sensor.View full abstractDownload PDF (2279K) -

JOURNAL FREE ACCESSRecently those who are paper for their off-set printing have made a severer request on the raw material, i.e. paper, because defects on the raw material are defects of their products after all. The raw material quality should be compliance with what downstream processing requires. Here we summarize the trend among the downstream processors, and propose a optimum inspection system which may fit to its trend and requirements. We further propose the date processing system, based on QC-CIM, to analyze & diagnose various inspection date for quality assurance.View full abstractDownload PDF (2299K) -

JOURNAL FREE ACCESSThe qualities of the wound rolls are known to have a significant relationship to the internal stress distribution. In order to observe the performance of wound rolls, it is essential to predict the in-roll stress profile accurately. A new numerical simulation method of predicting the in-roll stress is developed, where the effect of the axial nip distribution, center torque and tension loss are considered. The experimental verifications are also presented, which show the good agreement of the internal stresses between numerical and experimental results. The performances of two types of reels are demonstrated. One type is that the spool is transferred from primary to secondary arm, while the other type is that the spool moves on the horizontal rail and center torque can also be controlled. The numerical results clarify that axial nip distribution along the cross machine direction has a significant effect upon the in-roll stresses. Evaluating the internal stresses due to the bending of the roll from its gravity and nip loading, the latter type of reel shows to have a better profile of winding.View full abstractDownload PDF (3809K) -
