The object of this paper is the derivation of a model for lateral dynamics of an endless metal belt. The minimal configuration of a metal belt is a conveyor-belt over two cylindrical bend drums. In
order to ensure a plane surface the metal belt is pre-stressed to a high level. The main problem of this configuration is to guarantee perfect lateral tracking of the belt utilizing swiveling drum axes, which should guarantee a constant lateral position of the belt´s edges under all process disturbances and geometric imperfections. In order to design an appropriate controller a dynamic process model is derived from simple geometric parameters of the belt. Measured data from a test rig are utilized to estimate a parametric black-box model, and both analytical and experimental model are validated against experimental results. The region of validity of the linear models is evaluated and the performance of the analytical model is demonstrated.
