Description

Verfahren zur Herstellung von mit Farblacküberzügen versehenen Die Erfindung betrifft eine weitere Ausbildung des durch Patent 5o8 364 geschützten Verfahrens zur Herstellung von mit Farblacküberzügen versehenen Asbestzementschieferplatten und kennzeichnet sich der Hauptsache nach dadurch; daß die Randöffnungen der Eindrücke vor dem Aufspritzen des Farblacküberzuges mit Hilfe einer Druckplatte o. dgl. verengert werden. Hierdurch wird ein besseres Haften der Farbäste des Farblacküberzuges sowohl in der Schlikkerschicht als auch in der Platte selbst erzielt und etwa auftretende Zug- und Druckspannungen auf den unteren Teil der schwalbenschwanzförmigen Wurzeln des Farbüberzuges verteilt.Process for the production of die provided with colored lacquer coatings The invention relates to a further embodiment of that protected by patent 5o8,364 Process for the production of asbestos-cement slate panels provided with colored lacquer coatings and is mainly characterized by it; that the marginal openings of the impressions before spraying the colored lacquer coating with the help of a pressure plate or the like will. This results in a better adhesion of the colored branches of the colored lacquer coating as well achieved in the slip layer as well as in the plate itself and any occurring Tensile and compressive stresses on the lower part of the dovetail roots of the color coating distributed.

Da die Porenlöcher, wie eingangs erwähnt, eine nach unten etwa schwalbensdhwanzförmig sich erweiternde Gestalt erhalten, ist ein Heraustreten oder -wandern der Farbwurzeln oder -zapfen des Farbüberzuges unmöglich. Die erfindungsgemäße Form der Porenlöcher wird zweckmäßig dadurch geschaffen, daß die mit einem Zementschlicker versehene Asbestzementplatte, nachdem sie unter der Nadelstanze hindurchgegangen ist, mit einer Druckplatte behandelt wird, die auf die beim Stanzen der Löcher entstandenen Ränder oder Wulste der Poren drückt und so eine geringe Verengung des oberen Porendurchmessers unter gleichzeitiger Ebenung der Oberfläche der Dunststeinplatte hervorruft.Since the pore holes, as mentioned at the outset, are roughly dovetail-shaped towards the bottom Obtaining an expanding shape is a stepping out or wandering of the color roots or tapping of the paint coating impossible. The shape of the pore holes according to the invention is expediently created in that the provided with a cement slip Asbestos cement board after going under the needle punch with a printing plate is treated, which on the resulting when punching the holes Pressing the edges or bulges of the pores and thus a slight narrowing of the upper pore diameter while at the same time leveling the surface of the haze stone slab.
