Description
Es sind Abfahren bekannt, die Außenseite oder einen entsprechenden Teil eines Gegenstandes, z. B. Feldflaschen, bei Feuerverzinkung, Verbleiung, Verzinnung u. dgl. nicht metallisch zu überziehen, indem .man eine Schutzform mit einem Dichtungsmaterial, ζ. B. Borax oder auch Lehm, anbrachte und so den Überzug verhinderte. An diesem Verfahren ist sehr nachteilig, daß die SchutzformThere are known departures, the outside or a corresponding part of an object, e.g. B. canteens, for hot-dip galvanizing, Leading, tin-plating and the like not to be coated with metal by one Protective form with a sealing material, ζ. B. Borax or clay, attached and such prevented the coating. A very disadvantageous aspect of this process is that the protective form
ίο oder das Dichtungsmaterial mehr oder weniger zur Verunreinigung des Metallbades Veranlassung gab, abbröckelte, sich einseitig löste, wodurch nur eine mangelhafte Nichtverzinkung usw. der-gewünschten Teile eintrat. Der Gegenstand der vorliegenden Erfindung behebt diese Mängel bei der Feuerverzinkung u. dgl. bei mit Gewinde versehenen Teilen dadurch, daß der nicht metallisch zu überziehende Teil eines im übrigen mitίο or the sealing material more or gave less cause for contamination of the metal bath, crumbled off, turned one-sided solved, whereby only a deficient non-galvanizing etc. of the desired parts occurred. The subject matter of the present invention overcomes these shortcomings in hot dip galvanizing and the like. In the case of threaded parts, in that the part that is not to be coated with metal has an otherwise
so Metallüberzug versehenden Gegenstandes durch Anschrauben einer entsprechenden starren Schutzform geschützt wird. Wesentlich ist hierbei das durch das Anschrauben mögliche straffe Halten der Schutzform, die infolge ihrer festen Beschaffenheit nicht bröckelt, und daß sich jedes besondere Dichtungsmaterial erübrigt.thus metal plating the object is protected by screwing on a corresponding rigid form of protection. Essential is the tight holding of the protective form, which is possible by screwing on due to their solid nature does not crumble, and that every special sealing material unnecessary.
