Das den Gegenstand der Erfindung bildende Verfahren, aus einem Stück Pappe, Metall u. dergl. eckige oder ovale Schachteln von beliebiger Tiefe durch Ziehen in einer Form mittelst Stempels oder Domes herzustellen, besteht darin, dafs Matrizen oder Formen benutzt werden, deren obere Eintrittsenden so gegen einander versetzt liegen, dafs zunächst zwei gegenüberliegende Seitentheile des Pappstückes bei Einführung desselben in die Matrize mittelst des Stempels aufgebogen, und dann die Seitenkanten dieser Seitentheile in trichterförmige Aussparungen der Matrize hineingezogen werden, so dafs sie sich allmälig rechtwinklig nach innen an den Dorn oder Stempel anschmiegen. Auf diese vorher mit Klebstoff versehenen Seitenkanten werden dann entweder zwei von den tiefer liegenden Eintrittskanten der Form aufgebogene Seitentheile des Pappstückes herangeklappt und im unteren Theil der Matrize mit den Seitenkanten ersterer Seitentheile verbunden, oder diese Seitenkanten überlappen einander derart, dafs sie unmittelbar mit einander verbunden werden.The method forming the subject of the invention, from a piece of cardboard, metal and the like. Square or oval boxes of any depth by pulling in a shape To manufacture by means of punches or domes consists in using matrices or molds whose upper entry ends are so offset from one another that initially two opposite side parts of the piece of cardboard when it is introduced into the die bent up by means of the punch, and then the side edges of these side parts in funnel-shaped recesses of the die are drawn in so that they are gradually at right angles cling to the inside of the mandrel or punch. On these side edges previously provided with adhesive then either two side parts of the piece of cardboard bent up from the lower leading edges of the form folded up and in the lower part of the die with the side edges of the former Side parts connected, or these side edges overlap one another in such a way that they are directly be connected to each other.
Fig. ι bis 5 beiliegender Zeichnung zeigen in mehreren Schnitten zur Ausführung des beschriebenen Verfahrens hergerichtete Matrizen mit zugehörigem Stempel und Fig. 6 bis 8 einige Muster von Schachteln in schaubildlicher Darstellung.Fig. Ι to 5 of the accompanying drawings show in several sections for the execution of the described Process-prepared matrices with associated punch and FIGS. 6 to 8 show some samples of boxes in diagrammatic form Depiction.
Die Form ist mit einem durchgehenden Kanal P versehen, und zwei einander gegenüberliegende Eintrittskanten A1 derselben treten gegen ebenfalls einander gegenüberliegende Eintrittskanten A3 um ein passendes Stück vor. Dadurch werden zunächst zwei gegenüber-The mold is provided with a continuous channel P , and two opposite leading edges A 1 of the same protrude by a suitable distance against also opposite leading edges A 3. This means that two opposite

von den Eintrittskanten A1 der Matrize gefafst und aufgebogen, wenn der Stempel F das
Pappstück in die Durchgangsöffnung P der Matrize hineindrückt. Die vorstehenden Seitenkanten
e von T1 werden bei weiterem Vorgang des Stempels F allmälig rechtwinklig
nach innen umgebogen, indem sie in trichterförmige Aussparungen der Matrize hinein-(rücken
(Fig. 3 und Fig. 6 und 8), und legen sich dabei um den Stempel F.
einer Schachtel nach Fig. 6 und
weiterem Vorgang des Stempels F die vorher mit Klebstoff bestrichenen Seitentheile T2 des
Pappstückes an den tiefer liegenden Kanten A3 der Matrize (Fig. 2, 3 und 4) gegen die in
den trichterförmigen Aussparungen umgebogenen Seitenkanten e umgeklappt, so dafs bei
weiterem Vorrücken von Stempel und Arbeitsstück im unteren Theile der Matrize, bezw.
des Kanales P derselben, durch den Druck des Stempels die Verbindung der Pappstückkanten
e mit den daraufgeklappten Seitentheilen Γ2 stattfindet.Pages T 1 , Fig. 3, of the piece of cardboard grasped by the leading edges A 1 of the die and bent up when the punch F presses the piece of cardboard into the through opening P of the die. The protruding side edges e of T 1 are gradually bent inwards at right angles during the further operation of the punch F by moving them into funnel-shaped recesses in the die (Fig. 3 and Figs. 6 and 8), and thereby wrap themselves around the punch F.
a box according to Fig. 6 and
Further operation of the punch F, the side parts T 2 of the piece of cardboard previously coated with adhesive are folded over on the lower-lying edges A 3 of the die (Fig. 2, 3 and 4) against the side edges e bent in the funnel-shaped recesses, so that with further advancement of Stamp and work piece in the lower part of the die, respectively. of the channel P of the same, through the pressure of the stamp the connection of the cardboard piece edges e with the side parts Γ 2 folded on it takes place.
Bei Bildung einer Schachtel nach dem Beispiel Fig. 8 kommt das Aufklappen der Seitentheile T'2 in Fortfall. Der Pappstreifen ist in diesem Falle derart zugeschnitten, dafs die in der trichterförmigen Eckenaussparung der Matrize umgebogenen Kanten e mit ihren Enden einander überlappen, so dafs bei voraufgegangenem Bestreichen derselben mit Klebstoff eine unmittelbare Verbindung ohne weitere Seitentheile eintritt, wenn der Stempel F in dem Matrizenkanal P weiter vorgeschoben wird. An Stelle von Pappe kann zur Herstel-When a box is formed according to the example in FIG. 8, the opening of the side parts T ' 2 is omitted. The cardboard strip is cut in this case, so the bent in the funnel-shaped corner recess of the die edges e DAF with their ends overlap each other; so that in voraufgegangenem brushing thereof enters a direct connection without further lateral parts with adhesive when the stamp F in the Matrizenkanal P is advanced further. Instead of cardboard,
lung der Schachteln etc. auch Metall verwendet werden, wobei anstatt des Klebstoffes Lothzinn in Anwendung kommt.In the case of the boxes etc., metal can also be used, with soldering tin instead of the adhesive comes into use.
Die Pappe kann aus einem Stück geschnitten sein, Oder aus zwei kreuzförmig über einander gelegten und mit einander verklebten Stücken bestehen.The cardboard can be cut from one piece, or from two cross-shaped on top of each other pieces that are laid and glued together.
