Description

Verfahren zum Herstellen von Preß- oder Gießformen für Dachziegel mit gerauhter Oberfläche In dem Patent 523 750 ist ein Verfahren zum Herstellen von Preß- oder Gießformen für Dachziegel mit gerauhter Oberfläche beschrieben und unter Schutz gestellt, bei welchem die Mutterform, die zur Herstellung der erst zur Formung der Ziegel dienenden Preßformen Verwendung findet, eine Rauhung erhält, beispielsweise durch Auftragen von Sand: Hierdurch erhält auch jede von dieser Mutterform abgenommene,- der Herstellung .des Ziegels unmittelbar dienende Preßform eine derartige Rauhung und letzten Endes auch der mit dieser Preßform hergestellte Ziegel.Process for the production of compression molds or casting molds for roof tiles with a roughened surface In the patent 523 750 a process for the production of compression molds or casting molds for roof tiles with a roughened surface is described and protected Forming the brick-serving press molds is used, a roughening is obtained, for example by applying sand: This means that every press form removed from this mother mold - directly serving the production of the brick receives such a roughening and ultimately also the brick made with this press mold.

Das Maß. der durch Auftragen von Sand auf die Oberfläche der Mutterform zu erreichenden Rauhigkeit ist begrenzt. Eine sehr starke Rauhigkeit läßt sich nach diesem Verfahren nicht erreichen, weil nicht einfach an Stelle des Sandes noch grobkörnigere Bestandteile genommen werden können.The measure. that by applying sand to the surface of the mother mold The roughness that can be achieved is limited. A very strong roughness can be reduced This method cannot be achieved because it is not simply a coarser one instead of the sand Components can be taken.

Will man die Oberfläche der mit den Preßformen hergestellten Ziegel D ganz besonders stark aufrauhen, so wird erfindungsgemäß die Oberfläche der Mutterform mit Stahlbürsten ttreuht. Hierdurch ist es_ ferner auch t möglich, die Art der Rauhung auf der Oberfläche des Ziegels beliebig zu gestalten, beispielsweise Längs- oder Querstreifenrauhtnmg oder sog. Tupfenrauhung auszuführen, wobei die Mutterform mit den Stahlbürsten entweder in der Längs- oder in der Querrichtung oder durch Betupfen mit der Stahlbürste bearbeitet wird. Hierdurch können Ziegel hergestellt werden, bei denen nicht nur infolge der rauhen Oberfläche sehr bald eine schön wirkende Patina erhalten wird, sondern auch die Wirkung der -so entstehenden Patina von vornherein -beliebig bestimmt werden kann, je nachdem, ob man Längs- oder Querstreifen aufrauht oder das Aufrauhen durch Betupfen herbeiführt.If you want to roughen the surface of the bricks D produced with the press molds to a particularly high degree, according to the invention the surface of the master mold is made with steel brushes faithful. This also makes it_ t It is possible to design the type of roughening on the surface of the brick as desired, for example longitudinal or transverse roughening or so-called polka-dot roughening, the master form being worked with the steel brushes either in the longitudinal or in the transverse direction or by dabbing with the steel brush. In this way, bricks can be produced in which not only a beautiful patina is obtained very quickly due to the rough surface, but also the effect of the resulting patina can be determined from the outset, depending on whether one roughened longitudinal or transverse strips or the roughening is brought about by dabbing.
