Zusatz zum Patente 167232 vom 24. September 1904.*)Addendum to patent 167232 of September 24, 1904. *)

Patentiert im Deutschen Reiche vom 18. Juli 1905 ab. Längste Dauer: 23. September 1919. Patented in the German Empire on July 18, 1905. Longest duration: September 23, 1919.

Gegenstand vorliegender Erfindung ist eine Ausführungsform des Verfahrens der Patente 167232 und 167613, durch welche die Herstellung des Blockes, aus dem die Dreifarbenraster gewonnen werden, wesentlich beschleunigt und verbessert wird.The present invention is an embodiment of the method of the patents 167232 and 167613, through which the manufacture of the block from which the three-color raster is obtained is significantly accelerated and is improved.

Man verfährt hierbei in der Weise, daß man durch Übereinandergießen oder Übereinanderkleben der einzelnen dünnen, durchsichtigen Farbenschichten zunächst Platten in der Stärke von etwa ι mm herstellt. Diese Platten werden alsdann bis zur gewünschten Blockhöhe übereinandergelegt, nachdem sie an den Berührungsflächen mit dem Klebemittel versehen wurden, und nun durch hydraulischen Druck miteinander zu einem homogenen Block vereinigt.One proceeds here in such a way that one is poured or glued on top of one another of the individual thin, transparent layers of paint initially produce plates with a thickness of about ι mm. These Panels are then placed on top of one another up to the desired block height after they on the contact surfaces were provided with the adhesive, and now by hydraulic Pressure combined into a homogeneous block.

Die Vorteile dieses Verfahrens ergeben sich aus folgender Betrachtung.The advantages of this method result from the following consideration.

Zur Herstellung eines Blockes gemäß den Patenten 167232 und 167613 sind viele tausend Einzelschichten erforderlich. Soll der Raster z. B. 60 cm breit sein und 20 Linien pro Millimeter haben, dann sind 12000 Lagen erforderlich. Sollen diese Lagen nach und nach bis zur vollen Blockhöhe übereinander geschichtet werden, so kann hierzu nur ein einzelner Arbeiter verwandt werden. Werden aus den einzelnen Lagen aber zunächst Platten von etwa 1 mm Stärke gebildet, die dann zum Block vereinigt werden, so kann man eine beliebige Anzahl von Arbeitskräften beschäftigen und auf diese Weise wesentlich schneller arbeiten.Many thousands are required to produce a block according to patents 167232 and 167613 Single layers required. Should the grid z. B. be 60 cm wide and 20 lines per millimeter then 12,000 layers are required. Should these layers be after and are layered on top of each other up to the full block height, only one can be used for this individual workers are used. However, the individual layers are first made into panels about 1 mm thick, which are then combined into a block, so you can employ any number of manpower and thus become essential work faster.

In technischer Beziehung stellt das Verfahren aus folgenden Gründen eine Verbesserung dar:Technically, the method is an improvement for the following reasons dar:

Werden die einzelnen Lagen bis zur vollen Blockhöhe übereinander geschichtet, dann ist es nicht möglich, vollkommene Liniengradheit zu erzielen. Sobald nämlich der Block eine bestimmte Höhe erreicht hat, hat man einen mehr oder weniger weichen, plastischen Körper vor sich, welcher einerseits schon durch sein Eigengewicht, andererseits durch den auf ihn unvermeidlich beim Weiterarbeiten ausgeübten ungleichmäßigen Druck geringe Deformationen erleidet. Diese Deformationen erscheinen alsdann bei den Linienrastern als schwach wellenförmig verlaufende Linien.If the individual layers are stacked up to the full block height, then it is it is not possible to achieve perfect line straightness. As soon as the block has reached a certain height, one has a more or less soft, plastic one Body in front of you, which on the one hand by its own weight, on the other hand by reduce the uneven pressure inevitably exerted on him as he continues to work Suffers deformations. These deformations then appear in the line grids as slightly wavy lines.

Dieser Übelstand wird vermieden, wenn man zunächst Platten herstellt, welche eine so geringe Dicke haben, daß die einzelnen Lagen, aus denen sie bestehen, notwendigerweise parallel zu der ebenen Unterlage verlaufen müssen, auf welcher das Ubereinanderschichten erfolgt. Werden die Platten alsdann in der hydraulischen Presse zum Block vereinigt, so bleibt diese Parallelität im ganzen Block erhalten, denn der gleichmäßige Druck der Presse kann sie nicht mehr zerstören. This inconvenience is avoided if one first produces plates, which one are so thin that the individual layers of which they are made are necessarily must run parallel to the flat surface on which the layers he follows. If the plates are then combined to form a block in the hydraulic press, this parallelism remains in entire block, because the even pressure of the press can no longer destroy it.

Soll der Block nicht zu einzelnen Blättern aufgeschnitten, sondern zu langen Bändern aufgeschält werden, dann werden aus den etwa ι mm starken Platten zweckmäßig kreisrunde Tafeln gestanzt oder geschnitten und diese dann in der hydraulischen Presse zu einem zylindrischen Block vereinigt.Should the block not be cut into individual sheets, but into long ribbons are peeled, then the approximately ι mm thick plates are expediently circular Sheets are punched or cut and then combined in the hydraulic press to form a cylindrical block.
