KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung bezieht sich auf die Herstellung von Hülsen aus Pappe, Zelluloid und ähnlichem Material. Bei diesem Verfahren werden die Zargenwände der Hülse durch Niederziehen des Werkstückes in eine aus Backen bestehende Form gebildet und dann durch einen Preßstempel an der Schlußstelle mittels vorher aufgestrichenen Leimes verbunden. Darauf wird der Boden eingelegtThe present invention relates to the production of tubes from cardboard, celluloid and similar material. In this process, the frame walls of the sleeve by pulling down the workpiece into a Formed from jaws and then formed by a ram at the end point connected by means of previously applied glue. The floor is then laid on top
ίο und durch einen anderen Preßstempel der vorher mit Leim bestrichene Zargenrand umgebogen und an den Boden gepreßt.ίο and by another press ram of the The frame edge previously coated with glue is bent over and pressed to the floor.
In beiliegender Zeichnung sind in den Fig. ι bis 3 die hauptsächlichen Teile der zur Aus-Übung des Verfahrens dienenden Maschine schematisch dargestellt. Das Werkstück wird auf die mit Anlegekanten versehene Fläche cc der Backen b b aufgelegt; an den zu verbindenden Stellen ist dasselbe schon vorher mit Leim bestrichen. Sodann wird der Dorn d abwärts geführt und dadurch das Werkstück in die Form f der Backen b b gezogen, worauf der Stempel α die Schlußstelle der Hülsen zusammenpreßt.In the accompanying drawing, the main parts of the machine used to exercise the method are shown schematically in FIGS. The workpiece is placed on the edge surface cc of the jaws bb ; at the points to be connected the same is coated with glue beforehand. Then the mandrel d is guided downwards and thereby the workpiece is drawn into the form f of the jaws bb , whereupon the punch α compresses the end point of the sleeves.
Bei Hülsen mit Boden ist die Pappe so auf die Anlage der Fläche c c aufzulegen, daß die Bodenkante um so viel, als sie über den Boden greifen soll, über die Endfläche des Domes d übersteht. Der Pappboden wird in die überstehende Hülsenzarge, welche, von dem Preßstempel α zugehalten, um den Dorn d in der Form f liegt, hineingelegt und dann der Preßstempel e mit der Vertiefung f auf den schon vor dem ArbeitsVorgang mit Leim versehenen vorstehenden Zargenrand gedrückt. Dadurch wird derselbe umgebogen und fest an den Boden gepreßt. In the case of tubes with a bottom, the cardboard is to be placed on the surface cc so that the bottom edge protrudes beyond the end face of the dome d by as much as it should reach over the bottom. The cardboard base is placed in the protruding sleeve frame, which is held closed by the ram α , around the mandrel d in the form f , and then the ram e with the recess f is pressed onto the protruding frame edge that was provided with glue before the work process. As a result, it is bent over and pressed firmly to the ground.
Nun wird der Preßstempel e wieder geöffnet, der Dorn d mit dem Preßstempel a aus der Form / der Backen b b herausbewegt und der Preßstempel α ebenfalls geöffnet. Die fertige Hülse kann nun von dem Dorn d abgezogen werden. . : Now the ram e is opened again, the mandrel d with the ram a is moved out of the mold / jaws bb and the ram α is also opened. The finished sleeve can now be pulled off the mandrel d. . :
Die sämtlichen auswechselbaren Werkzeuge, als Backen b b, Dorn d, Preßstempel α und e, sind zum Heizen eingerichtet, damit die Pappe die gewünschte Form behält und die vorher mit Leim bestrichenen und trocken gewordenen Stellen durch die Wärme wieder klebrig werden, die Verbindung herstellen und sofort trocknen.All the interchangeable tools, as jaws bb, mandrel d, ram α and e, are set up for heating so that the cardboard retains the desired shape and the previously coated with glue and dry spots become sticky again due to the heat, make the connection and dry immediately.
