Abstract
In order to perform the high-speed paper feed in printers, it is indispensable to understand the deformation-force characteristics around the feed hole. This paper deals with the dynamic characteristics and the deforming speed's influence theoretically and experimentally. The main results are as follows: (1) Regardless of the deforming speed, the characteristics are composed of the section where the force increases exponentially, the sectionwhere the force increases linearly and the section where the force increases and decreases irregularly. (2) The dynamic and static characteristics can be explained by the model that the paper around the feed hole is composed of the circular stripes. (3) As the deforming speed becomes higher, the deform-force curve extends similarly. Because when the deforming speed is high, the fiber sliding speed and the fiber breaking speed can not follow the deforming speed.
