[en] Rolled target foils withstand due to their crystalline structure longer a heavy ion beam than evaporated targets. This fact is important for experiments with very heavy ions available now at the SUPER HILAC at Berkeley or at the UNILAC at Darmstadt, Germany. Because the crystalline disorientation of the targets by the heavy ion beam requires a frequent target exchange to prevent a deterioration of the energy resolution, a method was developed to produce large quantities of rolled targets with thicknesses below 1 mg/cm²
