Abstract

Ein Verfahren zum Herstellen einer Preßform, insbesondere zum Erzeugen von Dachziegeln zeichnet sich dadurch aus, daß die aus Metall, insbesondere Stahl oder Grauguß, bestehenden Formflächen gezielt aufgerauht werden, zum Beispiel durch Sandstrahlen, Auftragen verschleißfester Pulver oder dergleichen.
