mittelst einer Schablone.by means of a template.

Die vorliegende Erfindung betrifft eine Vorrichtung zum gleichzeitigen Bedrucken von Geweben mit zwei oder mehr Farben mittelst eines oder mehrerer Schablonenbiinder.The present invention relates to a device for simultaneous printing of Fabrics with two or more colors using one or more template binders.

In der Patentschrift 94973 ist bereits ein Verfahren zum Mustern von Flächen mittelst mehrerer Schablonen beschrieben worden, welches darin besteht, dafs die über einander gelegten Schablonen, auf welche die Farben von aufsen aufgebracht werden, wahrend des Auftragens oder nach jedem Auftragen beständig gegen einander verschoben werden, wobei zur Erzielung einer gröfseren Mannigfaltigkeit in der Zeichnung auch auf die dem zu bedruckenden Gewebe zugekehrte Unterseite der Schablone Farbe gebracht werden soll. Da diese Farbe auf die glatte Fläche der Schablone aufgebracht wird, ist beim Auflaufen" der Schablone auf . den Druckcylinder sehr leicht ein Verwischen der Farben möglich.In the patent specification 94973 a method for patterning surfaces is already mean several templates have been described, which consists in the fact that they are superimposed on each other laid stencils on which the colors are applied from the outside, during the Application or after each application are constantly shifted against each other, whereby to achieve a greater variety in the drawing also on the dem to be printed tissue facing underside of the stencil is to be brought color. Since this color is applied to the smooth surface of the stencil, when it comes up " the stencil. The printing cylinder can easily smear the colors.

Nach der vorliegenden Erfindung wird dieser Uebelstand dadurch vermieden, dafs die dem zu bedruckenden Gewebe zugekehrte Seite der Schablone mit Vertiefungen versehen ist, die mit der einen Farbe gelullt werden. Dies geschieht in der Weise, dafs auf die Unterseite der Schablone die eine Farbe so aufgetragen wird, dafs sie sowohl die Vertiefungen als auch die Aussparungen der Schablone ausfüllt. Die auf der glatten Unterseite der Schablone befindliche Farbe wird dann mittelst eines Schabers abgenommen,während die in den Aussparungen enthaltene Farbe zum .gröfsten Theil beim Ablaufen der Schablone von einer Führungswalze von dieser mitgenommen wird, von welcher die Farbe dann mittelst eines Schabers wieder abgenommen wird, während der noch in den Aussparungen der Schablone verbliebene Theil der Farbe durch eine auf die Aufsenseite der Schablone wirkende Filzwalze entfernt wird, deren Filzbekleidung in die Löcher der Schablone hineindringt. Es bleiben auf diese Weise lediglich die Vertiefungen der Schablone mit Farbe gefüllt und es werden dann die Aussparungen der Schablone von der Oberseite her mit einer anderen Farbe gefüllt. Die so vorbereitete Schablone wird mit dem zu bedruckenden Gewebe zusammen zwischen einem nachgiebigen Presser und einer Druckwalze hindurchgeschickt und giebt dabei die in den Vertiefungen und den Aussparungen enthaltenen Farben an das Gewebe ab.According to the present invention, this inconvenience is avoided in that the side of the stencil facing the fabric to be printed is provided with depressions which are lulled with one color. This is done in such a way that one color is applied to the underside of the stencil in such a way that it fills both the depressions and the recesses in the stencil. The color on the smooth underside of the stencil is then removed by means of a scraper, while the majority of the color contained in the recesses is carried along by a guide roller when the stencil runs off, from which the color is then removed again by means of a scraper , while the part of the color still remaining in the recesses of the stencil is removed by a felt roller acting on the outside of the stencil, the felt lining of which penetrates into the holes of the stencil. In this way, only the depressions of the stencil remain filled with color and the recesses of the stencil are then filled with a different color from the top. The stencil prepared in this way is sent through with the fabric to be printed together between a flexible press and a pressure roller and releases the colors contained in the depressions and recesses onto the fabric.

Auf der Zeichnung ist ein Theil einer derartigen Metallschablone in Fig. 1 in Ansicht und in Fig. 2 im Längsschnitt dargestellt. Fig. 3 zeigt die Druckmaschine im senkrechten Schnitt.In the drawing, a part of such a metal template is shown in FIG and shown in Fig. 2 in longitudinal section. Fig. 3 shows the printing machine in the vertical Cut.

Die Schablone α ist mit Aussparungen b sowie mit Vertiefungen c versehen, welche auf einer Seite der Schablone angebracht sind. Die Schablone ist über die beiden Cylinder d und e gelegt, welche auf den Wellen f und g befestigt sind. Die Welle g ist in dem festen Rahmen der Maschine gelagert, während die Lager der Welle f auf einem Schlitten h angeordnet sind, welcher auf Gleitschienen i verschoben werden kann, um die Schablone nach Belieben anspannen zu können. Auf demThe template α is provided with recesses b and with depressions c , which are attached to one side of the template. The template is placed over the two cylinders d and e , which are attached to the shafts f and g. The shaft g is mounted in the fixed frame of the machine, while the bearings of the shaft f are arranged on a carriage h , which can be moved on slide rails i in order to be able to clamp the stencil at will. On the

Claims

The ink container j is slidably mounted on the slide ft so that it approaches the cylinder d or can be removed from the same. The stencil lying on the cylinder d runs between the paint container j and the cylinder d and is coated with paint in the process. In order to remove the excess paint from the outside of the stencil, a scraper A mounted on the shaft is pressed against the stencil by means of loaded levers which sit at the ends of the shaft r. The color contained in the recesses b of the stencil comes into contact with the cylinder ^ when it hits the cylinder and, when the stencil α leaves the cylinder d,. completely or almost completely adhere to this and removed from it by the scraper η. The scraper η can be pressed more or less strongly against the outer surface of the cylinder d and lets the removed paint fall into the trough ο. The paint still adhering to the inner side of the stencil α is removed by a rotating cleaning roller ρ covered with felt before the stencil arrives at the next paint container. The felt lining of this roller ρ penetrates into the holes of the stencil and thus removes any paint that may still be in the same.

The second color is brought from the paint container t onto the inner surface of the stencil α and pressed through the recesses b of the stencil, while at the same time the color contained in the depressions c is printed on the material. The printing therefore takes place at the moment when the stencil is between the flexible press u and the pressure roller ν , so that the colors come exactly in the right place according to the pattern. The material to be printed is expediently carried and transported on by an endless cloth which runs over the roller ν. '■' .. '

After the printing is effected, the outer surface of the stencil is moistened with turpentine by a felt-covered rotating roller w. This roller is adjustable so they DAF's more or less current template can be geprefst against Uber'die roller e. . '■.

When the stencil has passed between n> and e , the moistened paint on the stencil is removed by a scraper χ , which can be pressed more or less strongly against the stencil in a suitable manner. If there should still be paint in the recesses c of the stencil, which the scrapers have escaped, it is removed by a rotating brush roller ^ which approaches the stencil or. can be removed from the same. The template is then passed under a cleaning roller ^ which approximates the template or. can be removed from the same, and is finally completely cleaned by the cleaning rails A covered with felt. These rails A can be pressed more or less strongly against the template.

The paint adhering to the surface of the cylinder e is removed by a scraper B , which can be pressed more or less strongly against the roller.

Of course, two or more colors can also be applied to each side of the stencil so that one can print with more than two colors. . ·
