Description

Verfahren zur Vergrößerung von Härte und Festigkeit von aus getrockneter Rohhaut hergestellten Maschinenteilen. Die Erfindung besteht in einem Verfahren; zur Vergrößerung der Härte und Festigkeit von aus !getrockneter Rohhaut hergestellten Maschinenteilen-, insbesondere von; Scheiben und Zahnrädern. Das Verfahren -besteht darin, daß die Teile mit Aldehyd,, insbesondere mit Formaldehyd, behandelt werden. Für die Behandlung der Teile kann gemäß dem Verfahren auch eine .Mdschung von Formalin und Spiritus verwendet werden. -kohhautmaschi= nemteile, welche mit dem die Erfindung bildenden Verfahren zur Erhöhung ihrer Festigkeit behandelt werden, können ohne Nachteil für ihren Zustand -dem Einfluß, beispielsweise von Wasser; ausgesetzt werden.Process for increasing the hardness and strength of dried Machine parts made from rawhide. The invention consists in a method; to increase the hardness and strength of dried rawhide Machine parts, in particular of; Discs and gears. The procedure - exists in that the parts are treated with aldehyde, especially formaldehyde. According to the method, a mixture of formalin can also be used for the treatment of the parts and alcohol can be used. -kohhautmaschi = nemteile with which the invention Formative processes to increase their strength can be treated without Disadvantage for their condition -the influence, for example of water; get abandoned.
