Description
Verfahren zur Erzielung eines scharfen Bruches bei durch Maschinen gefalzten Bogen. Beim Falzen von Bogen durch die Falzmaschine wird es für die Weiterverarbeitung als störend und hinderlich empfunden, daß der gefalzte Bogen einesteils an der nicht offenen Seite stärker bleibt als an der anderen und daß er andernteils vom zweiten Bruch ab lästige Falten zeigt, die keinen sauberen einwandfreien Bruch ermöglichen. Dies ist darauf zurückzuführen, daß nach dem zweiten Bruch die sich zwischen dem einmal gefalzten Bogen haltende Luft beim weiteren Falzen nicht entweichen kann und dadurch dem Bruch Widerstand entgegensetzt, wodurch die eingangs erwähnten Nachteile auftreten.Process for achieving a sharp break in by machines folded sheet. When the sheet is folded by the folding machine, it is used for further processing felt as annoying and a hindrance that the folded sheet on the one hand not on the open side remains stronger than on the other and that it is on the other part of the second Breakage shows annoying folds that do not allow a clean, faultless break. This is due to the fact that after the second break between the Once a sheet has been folded, air cannot escape during further folding and thereby opposes the breakage resistance, whereby the disadvantages mentioned at the beginning appear.
Nach dem den Gegenstand der vorliegenden Erfindung bildenden Verfahren werden diese Nachtr,ile dadurch beseitigt, daß in den zu falzenden Bogen an den Schnittpunkten zweier sich kreuzenden Falzkanten bzw. Bruchlinien Ausschnitte eingestanzt oder eingeschnitten werden, aus denen die Luft dann beim Falzen entweicht.According to the process which is the subject of the present invention these disadvantages are eliminated by the fact that in the sheet to be folded at the Intersections of two crossing fold edges or break lines cutouts punched or incised, from which the air then escapes during folding.
Das .Verfahren ist auf der Zeichnung in einem Ausführungsbeispiele erläutert, und zwar zeigen Fig. i einen im Dreibruch gefalzten Bogen, und Fig. 2 den Bogen vor dem Falzen mit de'n Ausschnitten.The .Verfahren is on the drawing in an exemplary embodiment 1 shows a sheet folded in three-folds, and FIG. 2 the sheet with the cut-outs before folding.
Wie auf der Zeichnung (Fig. z) -dargestellt, werden die Ausschnitte a in dem Schnittpunkte zweier beim Falzen sich in der Mitte kreuzenden Falzkanten bzw. Bruchlinien angebracht. Sie können ausgestanzt oder ausgeschnitten werden - - doch. betrifft dies nicht das Wesen der Erfindung -, und zwar entweder durch einen . besonderen Arbeitsvorgang vor dem Falzen oder während desselben oder auch schon bereits auf der Druckmaschine. Es werden längliche Ausschnitte, wie' auf der Zeichnung veranschaulicht, die bei der Weiterverarbeitung durch den Beschnitt in Wegfall kommen, vorgesehen.As shown in the drawing (Fig. Z), the cutouts a at the intersection of two folded edges that cross in the middle when folding or break lines attached. They can be punched out or cut out - - but. this does not concern the essence of the invention - either by one . special work process before folding or during the same or even before already on the press. There will be elongated cutouts, like 'on the drawing illustrated, which can be omitted during further processing due to the trimming, intended.
Ein besonderer Vorteil kann durch die Ausschnitte a noch dadurch erreicht werden, daß sie gleichzeitig zum Anlegen der Bogen benutzt werden können, derart, daß Nadeln zur gegebenen Zeit in die Ausschnitte eingeführt werden, die den Bogen vor dem Falzen in die richtige Lage bringen, wodurch das bisherige übliche zeitraubende Anlegen nach den Punkturlöchern ersetzt wird.A particular advantage can be achieved by the cutouts a that they can be used at the same time to lay out the arches, in such a way that that needles are inserted at the appropriate time into the cutouts that form the arch Bring it into the correct position before folding, eliminating the time-consuming process that was previously done Apply after the puncture holes is replaced.
