Wird die Schuhwerk-Sohlendoppelmaschine zum Annähen von Sohlen an Schuhwerk mit weichem Oberleder benutzt, so kommt es vielfach vor, daß sich das weiche Oberleder an dem Gelenk in Falten legt, und daß es hierdurch in die Aussparung der Nadel.stangenführung eintritt und von der Nadel durchstochen wird.Device for preventing the puncture of soft upper leather through the needle on shoe-sole double machines.
