Patentirt im Deutschen Reiche vom 20. März 1878 ab.Patented in the German Empire on March 20, 1878.
Zunächst werden durch Auswalzen oder entsprechende Operationen Hohlblechstreifen hergestellt, welche den in Fig. 2 der beiliegenden Zeichnung abgebildeten Querschnitt besitzen. Alsdann werden aus den so zubereiteten Blechen die Messerklingen in der Anordnung ausgestanzt oder durch entsprechende !Hilfsmittel ausgeschnitten, wie dies aus Fig. 1 des näheren hervorgeht. Abfall wird auf diese Weise nahezu vollständig vermieden.First of all, hollow sheet metal strips are formed by rolling or corresponding operations produced, which have the cross-section shown in Fig. 2 of the accompanying drawings. The knife blades in the arrangement are then punched out of the sheets prepared in this way or cut out by appropriate aids, as can be seen in more detail in FIG. 1. In this way, waste is almost completely avoided.
