Abstract
Very thin foil material is usually fed by roll-feeding devices. However, these devices can limit the feeding speed and cause damage to the foil surface finish. A promising alternative are electromagnetic systems. This technology is based on the working principle of a linear induction machine.
In this paper, a study is presented which examines the potential and limitations of this approach for foils. For this purpose, a parametric finite element analysis (FEA) model was developed using different ANSYS element types. With this model, the physical limits of the system, e.g. heating by the excitation of the windings and induction of eddy currents in the foil, the model is also used to optimise the ratio between feeding force and material heating.
The feeding technology presented here provides for a more efficient production and thus significantly contributes to shaping the change in the production industry.
