This paper describes theoretical and experimental studies of the deformation of paper in a nip unit. It is important to investigate the strain of the paper surface in the nip unit for a precise prediction of the paper transport characteristics. First, the deformation of the neutral plane was modeled by the multi-link model, and the strain of the paper surface was derived theoretically. Next, by an experimental setup of a nip roller mechanics with a short rubber-layered roller and a short steel roller, the strain of the paper surface was obtained experimentally. Finally by comparing the experimental results and numerical ones, the shear modulus of rigidity of paper was identified, and the physical parameter of paper was cleared.
