Description

Siebplatte aus feinem. Metalldrahtgewebe, das von einer grobgelochten Rahmenplatte getragen wird. Das Zusatzpatent 8727a3 zum Hauptpatent 864791 nimmt in Anspruch, daß feine metallische Siebbeläge in thermoplastische Kunststoffplatten mit Hilfe eines erhitzten Plätteisens eingedrückt werden. Es geht dabei davon aus, daß diese vollwandige Kunststoffstützplatten gelochte einheitliche Platten etwa aus Polyvynilchlorid sind. Es wurde nun gefunden, daß diese Platten technisch auch für beliebige Formgebungen und gekrümmte Flächen erheblich tragfähiger und billiger hergestellt werden können, indem man auf mechanisch tragfähigen, perforierten oder gelochten, Eisen- oder Metallplatten, etwa durch das an sich bekannte sogenannte Flammenspritzen oder Heißluftspritzen von Kunststoffen, wie Polyäthylen od. dgl., sehr haftfähige und chemisch widerstandsfähige Filme von o,5 bis a mm Dicke aufträgt. Dadurch wird bei höherer mechanischer Tragfähigkeit in erheblichem Umfang Kunststoff gespart.Sieve plate made of fine. Metal wire mesh, which is made of a roughly perforated Frame plate is worn. The additional patent 8727a3 to the main patent 864791 takes to claim that fine metallic screen linings in thermoplastic plastic panels be pressed in with the help of a heated flat iron. It assumes that this full-walled plastic support plates perforated uniform plates about are made of polyvinyl chloride. It has now been found that these plates also technically for any shape and curved surfaces considerably more stable and cheaper Can be made by looking at mechanically stable, perforated or perforated, iron or metal plates, for example through the so-called known per se Flame spraying or hot air spraying of plastics such as polyethylene or the like., very adhesive and chemically resistant films with a thickness of 0.5 to a mm. As a result, plastic is used to a considerable extent with a higher mechanical load-bearing capacity saved up.

Auf die so vorbereiteten Metallstützplatten mit einem thermoplastisch genügend dicken Überzug werden nun die metallischen Siebbeläge aufgelegt und durch ein erhitztes Plätteisen nach der im Patent 8727a3 beschriebenen Methode eingedrückt. An Stelle eines Plätteisens mit Handarbeit kann auch der Verbund aus der Metallstützplatte und dem flammgespritzten Überzug mit dem Siebbelag unter eine geheizte Presse gelegt werden. Auch durch geheizte Walzen ist die gleiche Verbindung herziustellen. Je nach Art des verwendeten Kunststoffes kann dieser durch Flammenspritzen oder durch Heißluftspritzen auf die Metallstützplatte gebracht werden oder als dünne Folien zwischen Siebbelag und Metallstützplatte gelegt werden.On the so prepared metal support plates with a thermoplastic A sufficiently thick coating is now placed on the metallic screen linings and passed through a heated flat iron pressed in using the method described in patent 8727a3. Instead of a flat iron with manual work, the composite of the metal support plate and placed the flame-sprayed cover with the screen lining under a heated press will. Even the same connection must be made by means of heated rollers. Depending on the type of plastic used, this can be achieved by flame spraying or be brought onto the metal support plate by hot air spraying or as thin Foils are placed between the screen covering and the metal support plate.
