Abstract
Sealing tools are used in a machine in which foils are guided between two sealing tools that on their sides facing the foil have bumps with uniform relative spacing T. Compensation for the tolerances between the sealing tools and the foils is achieved for a defined penetration depth of the bumps into the foil workpiece. The spacing T of the bumps is predetermined, and subsequently an experimental measurement of the force σis carried out that is necessary for the defined penetration depth of a test body of known geometry into the foils. Then, and with use of the force σapplied by the sealing machine that is determined as the quotient of the forces applied to the sealing tools per surface unit of measure of the sealing tools, the corrugated surface A required for the defined penetration depth is set based on the relation/σ.
