Description

B e s c h r e i b u n g Schreibleinen mit Wasserzeicheneffekt.D e c tio n n g Writing lines with watermark effect.

Für gewisse Zwecke, z. B. Ausweise verschienster Art, erscheint es wünschenswert über beschreib-oder bedruckbares appretiertes Gewebe (sog. Schreibleinen) zu verfügen, das in seiner Struktur den von Papier bekannten sog."Wasserzeichen-" effekt aufweist. Ein solches Material erschwert jede Fälschung bzw. unerwünschte Nachbildung der betreffenden Stücke, da die Musterung radierfest und nahezu unverwüstlich und ihre Erzeugung schwierig ist.For certain purposes, e.g. B. ID cards of various types, it appears desirable over writable or printable finished fabric (so-called writing lines) to have the so-called "watermark" known from paper in its structure has an effect. Such a material makes any counterfeit or undesirable Replica of the pieces in question, as the pattern is erasable and almost indestructible and it is difficult to generate.

Die Erfindung besteht in einem Sicherheits-Schreibleinen in Gestalt eines beidseitig mit einer Appreturmasse vorgestrichenen, geprägten, fertiggestrichenen, gedämpften und glatt gewalzten Trägergewebes, das in seiner Struktur eine der Prägung entsprechende, als Wasserzeicheneffekt in Erscheinung tretende Bemusterung aufweist.The invention consists in a security pen in the form one on both sides with a finishing compound prepainted, embossed, finished coated, dampened and smoothly rolled carrier fabric, the structure of which is one of the embossing has a corresponding pattern appearing as a watermark effect.

Das anliegende Muster ist wie folgt hergestellt : Das entschlichtete und gebleichte Trägergewebe üblicher Struktur '-' wurde beiderseits mit einer gefärbten, wasserlöslichen Appretur- masse, der auch Kunstharze beigefügt sein können, vorgestrichen und anschließend geprägt, wodurch an der Oberfläche der Bahn erhabene und vertiefte Partien entstanden.The attached pattern is produced as follows: The desized and bleached carrier fabric of the usual structure '-' was coated on both sides with a colored, water-soluble finish mass, to which synthetic resins can also be added, prepainted and then embossed, creating raised and recessed areas on the surface of the web.

Die Ware wurde nun mit derselben Appreturmasse fertig gestrichen, wobei die erhabenen Partien nur einen hauchdünnen Auftrag annahmen, während die vertieften Stellen voll ausgestrichen wurden. Beim anschließenden Dämpfen, wobei Wasserdampf auf, die fortlaufende Bahn geblasen wurde, unterlagen die vollausgestrichenen und satten Partien einer stärkeren Quellung als die dünn beschichteten Stellen.The goods have now been finished with the same finishing compound, whereby the raised areas only accepted a wafer-thin application, while the recessed areas have been fully streaked out. During the subsequent steaming, whereby Water vapor on the continuous web was blown, subject to the fully spread out and saturated areas of greater swelling than the thinly coated areas.

Durch das nachfolgende Kalandern mittels eines Roll-und Friktionskalanders, dessen Stahlwalze auf etwa 120-140 0 aufgeheizt und dessen Papierwalze mit einer Last von 30 bis 40 t gegen die Stahlwalze angedrückt war, wurde bewirkt, daß die erhabenen Partien der Bahn infolge ihrer sehr schwachen Beschichtung wesentlich heller erscheinen als die satt gestrichenen Stellen. Erst bei diesem Arbeitsgang trat der gewünschte Unterschied in j der Liohtdurchlässigkeit hervor, sodaß die Musterung als ein Wasserzeicheneffekt angesprochen werden kann. Gleichzeitig er- hielt die Ware durch das Kalandern die geforderte spiegelglatte und schreibfähige Oberfläche.The subsequent calendering by means of a roll and friction calender, the steel roller of which was heated to about 120-140 ° and whose paper roller was pressed against the steel roller with a load of 30 to 40 t, caused the raised parts of the web to be very weak as a result of their very weakness Coating appear much lighter than the heavily painted areas. It was only during this process that the desired difference emerged j the light permeability, so that the pattern as a Watermark effect can be addressed. Simultaneously the goods kept the required mirror-smooth and writable surface through calendering.

Naturgemäß zeigt die Rückseite der Ware den oben beschriebenen Wasserzeicheneffekt in einem viel schwächeren Grad, weil die negative Prägung wesentlich flacher zum Ausdruck kommt.Naturally, the back of the goods shows the watermark effect described above to a much weaker degree, because the negative embossing is much flatter to the Expression comes.
