Description

Randes beider Bogen und in vorbestimmter Lage mit Bezug auf den Papierbogen 2.Edge of both sheets and in a predetermined position with respect to the sheet of paper 2.

Es ist klar, daß beim Anlegen dieser genau geschnittenen Stellen an Anlegemarken 3 und 4 der kaschierte Wellpappebogen mit Bezug auf den darauf liegenden Papierbogen einwandfrei gerichtet werden kann, unabhängig von den Eigenschaften der Wellpappe. It is clear that when these precisely cut points are created at the mooring marks 3 and 4, the concealed Corrugated cardboard sheet must be properly aligned with respect to the sheet of paper lying on it can, regardless of the properties of the corrugated board.

Die Anzahl und/oder die Lage der Einschnitte kann natürlich vom dargestellten Beispiel abweichen. Im vorliegenden Fall liegen die Einschnitte im Papierbogen, welcher gleichzeitig mit dem Wellpappebogen geschnitten wird. Man könnte aber auch die Einschnitte so verlegen, daß nur der Wellpappebogen geschnitten würde.The number and / or the position of the incisions can of course differ from the example shown. In the present case, the incisions are in the sheet of paper, which is at the same time as the sheet of corrugated cardboard is cut. But you could also relocate the incisions so that only the sheet of corrugated cardboard would cut.

Das Verfahren kann etwa mit einer Vorrichtung wie derjenigen der F i g. 3 ausgeübt werden.The method can be carried out, for example, with a device such as that of FIGS. 3 can be exercised.

Bei 7 sind die Wellpappebogen gestapelt und werden durch einen Anschlag 8 zurückgehalten, derart, daß der jeweils unterst liegende Bogen vorgeschoben werden kann. Solche Vorrichtungen zum stückweisen Einführen der Bogen in eine sie bearbeitende Maschine sind an sich bekannt. Die einzelnen Bogen. werden in Richtung des Pfeiles 9 durch ein Förderband 10 mitgenommen.At 7 the corrugated cardboard sheets are stacked and held back by a stop 8, in such a way that that the bottom sheet in each case can be advanced. Such devices for piece by piece Introducing the sheets into a machine processing them are known per se. The individual arches. are taken along in the direction of arrow 9 by a conveyor belt 10.

: Bei 11 befindet sich der Stapel der vornehmlich vorgedruckten Papierbogen. Er liegt auf einem Tisch 12. Der Druck, gegenüber welchem die Bogen gerichtet werden müssen, befindet sich auf der Unterseite. . ■: At 11 is the stack of the predominantly preprinted sheets of paper. He lies on a table 12. The pressure against which the sheet is directed is on the bottom. . ■

Eine an sich gleichfalls bekannte Vorrichtung erfaßt die einzelnen obersten Bogen nacheinander und führt sie der geneigten Ebene 13 entlang zu Greifern 14 einer Fördertrommel 15, die sich in Richtung des Pfeiles 16 tangential zur Förderebene der Wellpappebogen dreht. Beim Vorbeiwandern vor einer Klebstoff auftragenden Walze 17 wird die Rückseite jedes einzelnen Blattes mit Klebstoff überzogen.A device, which is also known per se, is detected the individual uppermost sheets one after the other and leads them along the inclined plane 13 to grippers 14 of a conveyor drum 15 which extends in the direction of arrow 16 tangentially to the conveying plane of the sheet of corrugated cardboard turns. When walking past an adhesive-applying roller 17, the back of each single sheet covered with glue.

Erreicht ein Greifer 14 die tangentiale Lage mit dem Förderband 10, so gelangt an diese Stelle die Vorderkante eines Wellpappebogens, wonach Papier und Pappe zusammen unter die Trommel fahren und das Papier auf die Pappe angedrückt und geklebt wird. Weitere Druckrollen oder Zylinder 18 halten Papier und Pappe zusammen. Ferner wird vorausgesetzt, daß die Greifer 14 die Papierbogen 11 in gerichteter Lage erfassen, was kein Problem stellt.When a gripper 14 reaches the tangential position with the conveyor belt 10, the Leading edge of a sheet of corrugated cardboard, after which the paper and cardboard run together under the drum and the paper is pressed and glued onto the cardboard. Hold additional pressure rollers or cylinders 18 Paper and cardboard together. It is also assumed that the gripper 14, the paper sheets 11 in directional Capture the location, which does not pose a problem.

Neben jedem Greifer 14 ist endlich mindestens ein Schneidwerkzeug 19 in der Trommel 15 radial beweglich angeordnet. Dieses oder diese Schneidwerkzeuge liegen normalerweise im Innern der Trommel, werden aber nach 19' vorgerückt,- und zwar im Augenblick, wo.der Papierbogen mit dem Wellpaprpebogen in Berührung kommt. In diesem Augenblick werden also die weiter oben beschriebenen Einschnitte ausgeschnitten. Es ist selbstverständlich, daß die Umfangsgeschwindigkeit der Trommel 15 gleich sein soll der Fördergeschwindigkeit des Förderbandes 10. . In Wirklichkeit können mehrere solche Förderbänder nebeneinander liegen und die Schneidwerkzeuge zwischen den Bändern angeordnet sein. Ihr Vorrücken kann z. B. mit Hilfe einer Leitkurve stattfinden. '. ' . : ■-...Next to each gripper 14 there is finally at least one Cutting tool 19 arranged in the drum 15 so as to be radially movable. This or these cutting tools are usually inside the drum, but are advanced after 19 '- in the Moment where the sheet of paper with the sheet of corrugated cardboard comes into contact. At that moment, the cuts described above take place cut out. It goes without saying that the peripheral speed of the drum 15 is the same should be the conveying speed of the conveyor belt 10.. In reality there can be several such conveyor belts next to each other and the cutting tools be arranged between the bands. Your advance may e.g. B. take place with the help of a guide curve. '.

Die schematische Darstellung der Fig.4 zeigt, in einem größeren Maßstab, die gegenseitige Lage des mit Klebstoff versehenen Papierbogens 1Γ, des Wellpappebogens T und des Schneidwerkzeuges 19' im Augenblick, wo es tätig wird.The schematic representation of FIG. 4 shows, on a larger scale, the mutual position of the sheet of paper 1Γ provided with adhesive, the sheet of corrugated cardboard T and the cutting tool 19 'at the moment when it is activated.

Es könnten selbstverständlich andere Fördermittel der Papierbogen benützt werden als eine Trommel, z. B. Schwinghebel.Of course, other means of conveying the paper sheets could be used than a drum, z. B. rocker arm.
