Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Rundbrechen von Papierstreifen,
insbesondere zur Herstellung von solchen für Lampions u. dgl.
Es sind bereits Vorrichtungen zum Rundbrechen der zusammengefalteten Papierstreifen
mit Führungsnut bekanntgeworden, diese haben aber den Nachteil, daß der Radius der Führungsnut und damit derjenigen
des rundgebogenen Streifens konstant ist.The present invention relates to a device for breaking round paper strips, in particular for producing such for paper lanterns and the like.
Devices for breaking the folded paper strips with a guide groove have already become known, but these have the disadvantage that the radius of the guide groove and thus that of the curved strip is constant.
Mit Hilfe der vorliegenden Erfindung können geriffelte Papierstreifen von beliebigem Radius dadurch hergestellt werden, daß die Nut zum Führen des rundzubrechenden Streifens teilweise durch einen endlosen Riemen abgedeckt wird, dessen Abdeckungslänge durch eine schwenkbare Führungsrolle in Verbindung mit einer federnden fliegenden ao Spannrolle regelbar ist.With the aid of the present invention, corrugated paper strips of any Radius can be produced in that the groove for guiding the strip to be round to be broken partially through an endless one Belt is covered, the length of which is covered by a swiveling guide roller in connection with a springy flying ao tensioning pulley is adjustable.
Auf der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform beispielsweise dargestellt, und zwar zeigt:In the drawing, the subject matter of the invention is, for example, in one embodiment shown, namely shows:
Abb. ι eine Draufsicht, teilweise im Schnitt,Fig. Ι a plan view, partly in section,
Abb. 2 einen Schnitt durch die Arbeitsrolle, Fig. 2 a section through the work roll,
Abb. 3 und 4 den Papierstreifen in Längsund Querschnitt.Fig. 3 and 4 the paper strip in longitudinal and cross-section.
Der Papierstreifen α wird der Rolle h zugeführt, die die dem Format des Papierstreifens entsprechende Nut b aufweist. Ein Riemen / ist über Rollen m so geführt, daß er die Arbeitsrolle h etwa zur Hälfte überdeckt. The paper strip α is fed to the roll h which has the groove b corresponding to the format of the paper strip. A belt / is guided over rollers m so that it covers about half of the work roller h.
Bei Bewegung des Riemens / wird die Arbeitsrolle h, die sich um die Achse g dreht, mitgenommen und gleichzeitig auch der Papierstreifen o, der die Nut b dort verläßt, wo auch der Riemen / sich von der Peripherie der Arbeitsrolle h entfernt.When the belt / is moved, the work roll h, which rotates around the axis g , is carried along and at the same time the paper strip o, which leaves the groove b at the point where the belt / moves away from the periphery of the work roll h .
Der Papierstreifen α weist Riffelungen i auf, die in einer besonderen, dem Erfindungsgegenstand vorgelagerten Riffelmaschine hergestellt werden.The paper strip α has corrugations i , which are produced in a special corrugating machine upstream of the subject matter of the invention.
Um den Riemen die jeweils erforderliche Spannung zu geben, ist eine der Riemenführungsrollen auf einer beweglichen Achse gelagert, deren Hebel / unter der Wirkung einer Feder steht. 5"One of the belt guide rollers is used to give the belt the required tension mounted on a movable axle whose lever / under the action of a Pen stands. 5 "
Durch Schwenken der Rolle m kann der . Riemen f so geführt werden, daß er je nach Erfordernis eine mehr oder weniger große Fläche des Umfanges der Arbeitsrolle h bedeckt, wodurch der Radius des Gebogenen. verändert werden kann.By pivoting the role m can. Belt f are guided so that, depending on requirements, it covers a more or less large area of the circumference of the work roll h , whereby the radius of the curved one. can be changed.
