Paper handling technology related to sorting, feeding and stacking, has recently become of importance as a result of the development of high-speed,, high-resolution printers. Consequently, the clarification of paper processing characteristics is of vital concern. Although there have been numerous reports on metal processing characteristics, very few studies have been carried out on paper processing characteristics such as springback. In the previous paper, a mechanical model for paper behavior was proposed. The present study deals with paper processing characteristics related to stacking. Using the previously proposal mechanical model, an analysis was made of springback in the bending phenomenon for paper and the results were compared with those for metal plates. The results were successfully applied to make clear the correlation between springback and stacking stability in a printer. The main conclusions are as follows: (1) When the strain rate dependency was taken into consideration, close agreement was found between the observed and calculated values of paper in this springback analysis. (2) The staking stability increased as springback decreased. It was seen that greater paper thickness and the absence of affixing process results in better staking characteristics.
