KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Herstellung von Wasserzeichen in Papier während der Erzeugung auf der Papiermaschine erfolgt meistenteils mittels Vordruckwalzen, welche die in Draht ausgeführten Muster auf ihrer Oberfläche aufgelöthet tragen. Es wurden auch bereits mit in Filz eingewebten Mustern sogenannte markirte Papiere hergestellt. Die durch diese Filze hergestellten Markirungen können, da sie durch Weben hergestellt wurden, nur gerade bezw. schräge Linien bilden; auch können nur zusammenhängende, aber nicht einzeln stehende Wasserzeichen gebildet werden. Die Muster traten auch nicht genügend hervor, so dafs die erzielten Markirungen nur wenig Schärfe besafsen. Besonders war es bisher auch unmöglich, auf den sogenannten Selbstabnahmepapiermaschinen, die mit Obertuch versehen sind, andere als die vorstehend beschriebenen Markirungen mit gewebten Filzen, bei welchen sich Muster an Muster reiht, herzustellen. Auch stellte die spröde Cellulosepapiermasse, die ja namentlich auf solchen Selbstabnahmepapiermaschinen verarbeitet wird, den Markirversuchen mit Wasserzeichen in Abständen von einander durch Vordruckwalzen solche Hindernisse entgegen, dafs bis jetzt Wasserzeichen in Abständen von einander auf diesen Maschinen, ebenso aber auch auf anderen gewöhnlichen Papiermaschinen mit mehreren Pressen in reinem Cellulosepapier überhaupt nicht herzustellen sind.The production of watermarks in paper during the production on the paper machine is mostly done by means of pre-pressure rollers, which the pattern executed in wire on their surface dissolved. It has also already been woven into felt Patterns of so-called marked papers are made. The markings made by these felts can, since they were made by weaving, only bezw. form oblique lines; only connected, but not individual watermarks are formed. Neither did the patterns sufficiently so that the markings obtained were not very sharp. Particularly it was previously impossible to use the so-called self-acceptance paper machines, the are provided with an upper cloth, other than the markings described above with woven ones To produce felts, in which pattern follows pattern. Also presented the brittle cellulose paper pulp, which is processed specifically on such self-acceptance paper machines the marking attempts with watermarks at a distance from one another by pre-pressure rollers are countered by such obstacles, that up to now watermarks at intervals on these machines, but also also on other ordinary paper machines with several presses in pure cellulose paper cannot be produced at all.
Nachstehend ist nun ein Verfahren beschrieben, durch welches beliebige einzelne Wasserzeichen in einfacher Weise angebracht werden können.A method will now be described by which any individual watermark can be attached in a simple manner.
Es werden den herzustellenden Wasserzeichen entsprechende Muster mit der Hand oder mittels einer Maschine durch das Tambourir-, das Soutachir- oder ähnliches Verfahren auf einem beliebigen Filz angebracht. Ebenso können aber auch fortlaufende oder sich an einander reihende Gebilde hergestellt werden.Patterns corresponding to the watermarks to be produced are made by hand or by means of one machine through the tambourir, the soutachir or similar process on one any felt attached. But they can also be continuous or connected to each other serial structures are produced.
Die so hergestellten Muster befinden sich meist an der Oberfläche, sie bilden eine ziemliche Verdickung der betreffenden Stelle und bewirken eine starke Pressung der Waare, wenn diese mit dem Filze zwischen den Walzen hindurchgeht, wodurch genügend scharfe Wasserzeichen entstehen.The patterns produced in this way are mostly on the surface, they form quite a bit Thickening of the affected area and causing a strong compression of the goods, if this goes through with the felt between the rollers, creating sufficiently sharp watermarks develop.
Infolge des Anbringens der Muster auf dem fertigen Filze kann ihnen jede beliebige Form und jeder beliebige Abstand gegeben werden.As a result of applying the pattern to the finished felt, they can be of any shape and any distance can be given.
