Friction Control between Paper and Roller for Web Handling System

本研究以接触力学为基础，建立输送连续纸与旋转辊间摩擦特性的理论预测模型，并将该模型应用于高速生产的造纸机和新闻印刷机等实际纸幅输送系统中，根据纸张表面形貌的观测结果，建立了纸张与钢材的接触模型，并结合实验结果成功地建立了纸幅与钢辊间摩擦特性的理论预测模型，核查。2005年，对上述理论模型进行了扩展，建立了预测卷筒纸与钢辊之间发生打滑的理论模型，预测结果与实验结果吻合良好，在此基础上提出了无缺陷卷筒纸输送系统的新概念。

This research aims to develop the theoretical prediction model for friction characteristics between transporting continuous paper and rotating roller based on the contact mechanics and to apply the model developed to the actual web handling system such as paper making machine and news printing machine with high production speeds.In 2003 and 2004, the contact model between paper and steel was constructed based on the observation results of paper surface topography, and then the theoretical prediction model of friction characteristics between paper web and steel roller was formulated successfully with experimental verifications. Moreover, the prediction model for web wrinkling under transportation due to roller skew and friction between web and roller was also presented.In 2005, extending the above theoretical model for predicting the onset of slippage between web and steel roller was formulated, and predicted results agreed well with experimental results.Based on these results, the new concept of web transportation system without generating defects was presented.
