PATENTANSPRUCH:PATENT CLAIM:Verfahren zum Herstellen von U-förmigen Schienen-Klemmplatten aus gebrauchtem Eisenbahn-Oberbaumaterial,
dadurch gekennzeichnet, daß alte Schienen-Verbindungslaschen in mehreren
Walzschritten auf den Querschnitt der U-förmigen Klemmplatten gebracht und dann unter Wegfall der gelochten Abschnitte in Klemmplatten
zerschnitten werden, die anschließend das S chraubendurchgangsloch erhalten.Process for the production of U-shaped rail clamping plates from used railway track material,
characterized in that old rail connecting straps in several
Rolling steps brought to the cross-section of the U-shaped clamping plates and then omitting the perforated sections in clamping plates
are cut, which then get the screw through hole.In Betracht gezogene Druckschriften:
