  Verfahren zum Gerben von Häuten und Fellen. 



   Vorliegende Erfindung betrifft ein Verfahren zum Gerben von Häuten und Fellen, welches von den bisherigen, allgemein   üblichen Gerbvcrfahren wfsent ! ic( < abweicht. Das   Verfahren besteht darin, dass die Häute, nachdem sie in bekannter Art durch   Behandlung   mit Kalk (Kalkungsprozess) enthaart worden, zwei oder mehr Stunden (je nach ihrer Dicke) in einer mehr oder weniger gesättigten und bis auf   44-500 C angewärmten Sole (vor-   zugsweise Steinsalz bezw.   Sumpfsalzlösung)     ausgeweicht   werden.

   Die in der Sole ausgeweichten Häute werden darauf einer   10-20 Stunden anhaltenden Anräucherung unter-     worfen   und zu diesem Zwecke auf Holzgittern ausgebreitet oder an Haken in der   Raucher-   kammer aufgehängt, in   wolche   durch Verbrennen von vegetabilischem Material erzeugter Ranch eingelassen wird. Die angestellten Versuche haben ergeben, dass   überaus befriedigende   Resultate erzielt werden, wenn man als rauchbildenden Brennstoff Stroh,   Dünger, al)-   gefallenes Laub, Nadeln und Zweige von Nadelhölzern verwendet.

   Zum Schluss werden die Häute nach dem Anräuchern in einer schwachen Lösung (ungefähr 15   cm3   des im Handel vorkommenden Vitriolöls auf   10 l   Wasser) von Schwefelsäure geweicht, wobei man dieselben in der Lösung einige Stunden lang bis zur vollständigen Entfernung des Salzes liegen lässt. 



   Die auf die beschriebene Weise behandelten Häute sind weich (sammetartig beim Anfühlen) und elastisch und eignen sich für jegliche Zwecke. Es können nach diesem   Verfahren Häute   und Felle jeglicher Art von Ochsen, Kühen, Schafen, Ziegen, Pferden usw. behandelt werden. Für die Felle ist das Verfahren ganz dasselbe, nur dass dieselben nicht   gekalkt (abgehaart) werden.

  Process for tanning hides and skins.



   The present invention relates to a method for tanning hides and skins, which differs from the previously generally used tanning methods! ic (<deviates. The procedure consists in that the skins, after they have been depilated in a known manner by treatment with lime (liming process), for two or more hours (depending on their thickness) in a more or less saturated and up to 44- 500 C warmed brine (preferably rock salt or swamp salt solution) can be soaked.

   The skins soaked in the brine are then subjected to a 10-20 hour long fumigation and for this purpose they are spread out on wooden grids or hung on hooks in the smoking room, into which the ranch made by burning vegetable material is let into. The experiments have shown that extremely satisfactory results are achieved if straw, fertilizer, al) fallen leaves, needles and branches of coniferous wood are used as smoke-forming fuel.

   Finally, after fumigation, the skins are soaked in a weak solution (about 15 cm3 of the commercially available oil of vitriol to 10 liters of water) of sulfuric acid, leaving them in the solution for a few hours until the salt is completely removed.



   The skins treated in the manner described are soft (velvety to the touch) and elastic and are suitable for all purposes. Hides and skins of all kinds from oxen, cows, sheep, goats, horses, etc. can be treated with this method. The process is completely the same for the skins, only that they are not limed (haired off).
