Abstract
  P-com. Co., Ltd. is in charge of sheet finishing operations such as roll wrapping, sheet cutting and wrapping of paper sheets for Nippon Daishowa Paperboard Tohoku Co., Ltd. In the sheet finishing process, a ream feeding work by hand is very hard and there are many kinds of works. Although it is difficult to mechanize the process of a ream feeding, an automatic ream feeding has been required for cost reduction in this process. So we have solved such problems by development of semi-automatic ream feeding.
  In this paper, an operating experience and a development of Semi-automatic Ream Feeding System are introduced. After installing the system, we have been released from hard works and engaged in observing the sheet finishing process.
  The Semi-automatic Ream Feeding System was developed by Nippon Daishowa Paperboard Tohoku Co., Ltd., P-com. Co., Ltd. and SERVOARM Co., Ltd.

Operating Experience of Automatic Coil Wrapping Machine

Masayuki Saito
Nakoso Jujo Paper Industrial Corporation

Abstract
  CCP (Carbonless Copying Paper), produced in Nippon Paper Industriesf Nakoso mill, is sensitive to pressure. Because of this, rolls of CCP had been manually packed in corrugated cardboard boxes to protect them from the bruises in the transportation. As the production volume grows, manual packing is no longer efficient. Therefore the semi-automatic wrapping machine using plastic stretch film was adopted. With the raising concern over environmental issues, recently our customers have a serious problem with the disposal of the plastic film used for CCP packing. We have developed the new original wrapping paper to eliminate this problem. The features of this wrapping paper are as follows: using no plastic film, recyclable, shock absorbing, damp proof, etc. With this new wrapping paper we have started the exceptional full-automatic wrapping machine for CCP, which has an automatic labeler, a palletizing robot, etc.
  In this report the characteristics of our new original wrapping paper and our operation experience of the full-automatic wrapping machine are presented.

Retention Aid for Fillers Using in the Process of Deinked Pulp Manufacturing

Kazushige Inaoka
Research & Development Dept., Paper Chemicals Division, Harima Chemicals, Inc.

Abstract
  An inorganic particle called filler is added to printing paper for the purpose of improving optical characteristics and printability of the paper. However, the most of fillers are detached from pulp to water in the process of deinked pulp manufacturing, and it becomes the industrial waste in drainage process.
  In such a situation, we started our research based on a concept to reduce the amount of waste in the drainage process, and developed gretention aid for fillers using in the process of deinked pulp manufacturingh. We think that this development could improve the retention of fillers dramatically compared with other coagulant and flocculant due to a formation of ionic macromolecule and an improvement of the interaction between this chemical and fibers, fines and fillers.
  In this report, we introduce a characteristic and an effect of this chemical with showing application results at the actual machine.

Hidekazu Takahashi
Customer Service Dept., EAGLE INDUSTRY Co., Ltd.

Abstract
  In a pulp & paper plant, many numbers of varieties of pumps are utilized such as water pumps, pulp pumps and chemical pumps all through the production processes from digesting to painting. Recently, a mechanical seal has been selected as a standard sealing device for such pumps. A cartridge seal is coming into wide use for work improvement, for being easy to handle and for installing correctly. And then the cartridge seal is used not only non-flushing use but non-cooling use in a plant. Additionally, the cartridge seal with emergency seal is developed for pulp pumps. When a mechanical seal doesnft work and leakage starts, the emergency seal installed in the cartridge seal works and can use for a certain period. I will introduce the latest technology trend about the cartridge mechanical seal for the pulp &paper plant.

Abstracts
  Accurate estimation of timber volume in commercial plantation can serve the industry as well as the environment than sustains them. A robust estimation methodology will help the plantation industry to efficiently manage this costly and long term investment to get the utmost return. Here, we investigated an approach to estimate timber volume in several Eucalyptus globulus plantation plots of varying ages in Chile.
  Empirical relationships between temporal satellite imageries (Landsat ETM+) derived spectral feature and timber volume were investigated. A total of 12 Landsat ETM+ scenes, both radiometrically and geometrically corrected, were selected to match with the dates of ground truth allometry data. Landsat ETM+ has a ground resolution of 30 meters with a swath width of 185 km and visits the same position of the earth every 16 days making it suitable for monitoring plantations throughout a longer period of time with reasonable costs. Allometry data from a total of 8 plots spanning over four years (1999 `2004) were used. The area of the plots ranged from 30 to 150 ha and trees were planted between year 1992 and year 2000. Allometry data included diameter at breast height (DBH), height of tree (H) of individual trees at selected subplots (0.02 ha) within each plot, collected by plantation management staff.
  Mid-IR band 5 of ETM+ followed by the green band of ETM+ has the strongest correlation with timber volume for our study area. Out of several vegetation indices, Specific Leaf Area Vegetation Index (SLAVI), which uses mid-IR band 5, showed strongest linear relationship with volume. The best relationship was used to estimate total volume in each plantation plot and to produce spatial volume map. Comparison between total estimated volume and actual observed volume at each plot showed the estimation accuracy was considered satisfactory. Spatial maps could be of importance for efficient forest management.

Material Analysis Center, Oji Paper Co., Ltd.

Abstract
  It was commonly found that the aging and the manufacturing conditions were influenced on the surface properties of the paper. We assumed that the change of the surface properties was caused by the bleeding of the low-molecular-mass compounds to pulp fiber surface. In order to confirm this assumption we carried out the surface analysis of handsheets using XPS and TOF-SIMS.
  A handsheet was prepared from a hardwood pulp. TOF-SIMS and XPS analysis showed that the bleedable compounds, such as C-C chemical bonds increase on the surface of the sheet at high temperature.

Keywords: bleeding, pulp, surface analysis, TOF-SIMS, XPS
