Description
Verfahren zum Durchsichtigmachen von Papierblättern an bestimmter Stelle, vorzugsweise für Fensterbriefumschläge. Die vorliegende Erfindung betrifft ein. Verfahren zum Durchsichtigmachen von Papierblättern an bestimmter Stelle, insbesondere zur Herstellung von Fensterbriefumschlägen.Method for making sheets of paper transparent at certain Place, preferably for window envelopes. The present invention relates to a. Process for making sheets of paper transparent at a certain point, in particular for the production of window envelopes.
Bisher werden Papiere an bestimmter Stelle auf folgende Weise durchsichtig gemacht: Die betreffenden Stellen werden mit Lakken, Harzen, ölen oder einem sonstigen geeigneten Durchsichtigmachungsmittel versehen. Dann läßt man dieses Mittel bei gewöhnlicher Temperatur auf das Papier einwirken und trocknen; oder die mit dem Duichsiidhtigmachungsmittel versehenen Papiere werden einem erwärmten Raum zugeführt. Bei: diesem Verfahren erfolgt sowöhl die Dumchsichtigmachung der - Papiere wie auch die Trocknung des betreffenden Dwrchsichtigmadamgsmittels rascher als' bei dem obergenannten Verfahren.So far, papers have become transparent at a certain point in the following way made: The affected areas are made with lacquers, resins, oils or something else provided with suitable transparency means. Then you leave this remedy at act on the paper at ordinary temperature and dry; or the one with the Papers provided with anti-absorbing agents are fed into a heated room. In this process, both the paper and the papers are made clear the drying of the cosmetic agent in question is quicker than that of the above-mentioned one Procedure.
Dies zweite Verfahren hat aber den Nachteil, daß die Wärme, welche den ganzen Rauar erfüllt, die Papiere leicht ungünstig beeinflußt; die Farben werden leicht blaß oder sonstwie verändert.This second method has the disadvantage that the heat, which fills the whole room, slightly unfavorable influences on the papers; the colors will be slightly pale or otherwise changed.
Es ist ferner bekannt, -ein endloses Band, das mit einem geeigneten Durchsichiigm.achungsmittel getränkt ist, so lange auf das Papier durch teilweise beheizte Stempel aufzupressen, bis das Papier durchsi@c'htig ist.It is also known -an endless belt with a suitable Sealing agent is soaked so long on the paper through partially Pressing on heated stamps until the paper is transparent.
Nach dem Verfahren nach vorliegender Erfind'wng wird eine mit einem Durch:sich:tigmachwngsmittel versehene Stelle der zu behandelnden Papierblätter in den Wirkungsbereich der Heizfläche von wandernden, elektrisch erwärmten, der Größe und Form jener durchsichtig zu machenden Stelle entsprechenden Heizkörpern gebracht und so lange in dieser Lage belassen, bis die Durchsi-c'htigmac'hung und Trocknung vollzogen ist.According to the method according to the present invention, a with a Point of the paper sheets to be treated which has been provided with a stimulating agent in the area of action of the heating surface of migrating, electrically heated, the Size and shape of the place to be made transparent corresponding to radiators brought and left in this position until the breakthrough and Drying is complete.
Nach diesem Verfahren bleiben vom DurchsIchtigmachungsmittel nicht bedeckte Stellen des Papiers denn schädlichen Einfluß von Trockenwärme entzogen und daher der Gefahr einer Änderung in Ton und Farbe nicht ausgesetzt.After this procedure, there are no persistent threats Covered areas of the paper because the harmful influence of dry heat is withdrawn and therefore not exposed to the risk of a change in tone and color.
Das vorliegende Verfahren l,äßt sich vorteilhaft mit Hilfe von Einrichtungen, durchführen, wie sie auf der Zeichnung beispielsweise dargestellt sind.The present method can be advantageously carried out with the aid of facilities perform as shown in the drawing, for example.
In der Zeichnung ist mit a das durchsichtig zu machende Papier und mit b der entsprechende Heizkörper bezeichnet. Abb. r zeigt schematisch die Lagerung des Papiers a über dem entsprechenden Heizkörper b, während Abb. z die Lagerung des durchsichtig zu machenden Papiers a unmittelbar auf dem entsprechenden Heizkörper b schematisch zeigt. In Abb. 3 und q. sind zwei Arten der Wanderung mit endlosem Band oder endloser Kette schematisch angedeutet, während Abb. 5 das Schema der Wanderung des Heizkörpers nach Art eines russischen Karussells andeutet.In the drawing, a is the paper to be made transparent and with b denotes the corresponding radiator. Fig. R shows schematically the storage of the paper a over the corresponding radiator b, while Fig. z shows the storage of the paper to be made transparent a directly on the corresponding radiator b shows schematically. In Fig. 3 and q. are two types of hike with endless Band or endless chain indicated schematically, while Fig. 5 shows the scheme of the migration of the radiator in the manner of a Russian carousel.
Nachdem die Papierblätter a in bekannter Weise je an der gewünschten Stelle und in gewünschter Größe und Form mit einem Durchsichtigmachumgsmittel versehen sind, werden sie j e eines nach dem andern auf ein. Transportband abgelegt, in welches elektrisch beheizte Heizkörper b von der Größe und Form der durchsichtig zu machenden Stellen eingebaut ..sind.After the paper sheets a in a known manner depending on the desired Place a clearing means in the desired size and shape are, they will each one after the other one at a time. Conveyor belt stored in which electric heated radiator b on the size and shape of the see-through places to be made ... are built in.
Die Papierblätter werden entweder unmittelbar aui die Heizkörper gelegt oder in einem entsprechenden Abstande darüber angebracht.The sheets of paper are either placed directly on the radiators or attached at a corresponding distance above.
Nun wandern die einzelnen Papierblätter a je mit dem unter ihnen befindlichen Heukörper auf dem Transportband, bis dieses auf der Walze Y2 umgelenkt wird (Abb. ;3 und 4); an dieser Stelle rutschen die Blätter vom Transportband herab und stapeln sich von selbst auf. Die Zeit, die vom Auflegen der Blätter auf das Band bis zurr Abrutschen vergeht, kann reit der Temperatur der Heizkörper derart abgestimmt werden, daß dann das Durchsiehtigmachungsmittel auch völlig trocken ist. Die mechanische Bewegung der Heizkörper kann z. B. auch. mittels einer Einrichtung ähnlich einer russischen Schaukel bewerkstelligt werden (Abb.5).Now the individual sheets of paper move along with the one below them Hay body on the conveyor belt until it is deflected on roller Y2 (Fig. ; 3 and 4); at this point the sheets slide off the conveyor belt and pile up by itself. The time from placing the sheets on the belt to the r Slipping disappears, the temperature of the radiator can be adjusted so that that then the clarifying agent is also completely dry. The mechanical Movement of the radiator can e.g. Belly. by means of a device similar to a Russian swing (Fig.5).
