Description
Die Erfindung betrifft ein Kreismesser zumThe invention relates to a circular knife for
Längsschneiden von Papiersträngen vor dem Falztrichter einer Rotationsdruckmaschine mit einem Ausschnitt an der Schneidkante, der den Papierstrang stellenweise unbeschnitten" läßt.Lengthwise cutting of paper strands in front of the former of a rotary printing press a cutout at the cutting edge that leaves the strand of paper uncut in places.
Ein Kreismesser dieser Art ist bereits dazuA circular knife of this type is already included
benutzt 'worden, abwechselnd Einzelblätter und Doppelblätter* herzustellen, wobei der Ausschnitt des Kreismessers notwendigerweise die Länge des Zylinderumfanges hat.used 'to produce alternating single sheets and double sheets *, with the Section of the circular knife necessarily has the length of the cylinder circumference.
Ferner ist auch vorgeschlagen worden, einIt has also been proposed to use a
Kreismesser zum stellenweisen Schneiden eines mehrfach zu falzenden Papierbögens zu dem Zwecke zu verwenden, einen möglichst glatten Falz zu erzielen.Circular knife for cutting a sheet of paper to be folded several times to use the purpose of achieving the smoothest possible fold.
Demgegenüber ist gemäß der Erfindung der Kreismesserumfang, der bei zwei Platten im Druckzylinderumfang zu diesem in dem Verhältnis von 1:2 steht,' nur so weit ausgeschnitten, daß bei dem Abwickeln des Messers auf dem Papierstrang an der Falzkante eine Stelle ungeschnitten bleibt, die durch das nachher erfolgende Querschneiden geteilt wird und zum Versiegeln des Falzproduktes dient. Eine so hergestellte Zeitung bleibt so lange gesiegelt, bis sie von dem Käufer ge- -öffnet wird.In contrast, according to the invention, the circumference of the circular knife, which is in the case of two plates The circumference of the printing cylinder is in the ratio of 1: 2 to this, 'only cut out so far, that when unwinding the knife on the paper strand at the folded edge a Place remains uncut, which is divided by the subsequent cross-cutting and serves to seal the folded product. A newspaper made in this way stays that way long sealed until it is opened by the buyer.
An sich ist das Versiegeln von Zeitungen bekannt. Z, B. hat man versucht, die Papierlagen der Zeitung an der Vorderspitze durch .Perforieren oder Leimen miteinander zu verbinden oder an dieser Stelle eine Heftklammer anzubringen. Diese Maßnahmen haben aber in der Praxis keinen Anklang gefunden, weil durch das Perforieren die Papierlagen nur sehr unvollkommen zusammengehalten werden, während das Leimen oder Heften das Anbringen eines teueren Apparates erforderlich macht, der außerdem im Betriebe sehr empfindlieh ist. Diese Nachteile sind bei der Erfindung nicht vorhanden. In itself is the sealing of newspapers known. For example, an attempt has been made to pull through the paper layers of the newspaper at the front tip .Perforate or glue to join together or a staple at this point to attach. However, these measures have not met with approval in practice because the paper layers are only held together very imperfectly by the perforation, while gluing or stapling the attaching requires an expensive apparatus, which is also very sensitive in the company is. These disadvantages are not present in the invention.
Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise dargestellt; es zeigt The drawing shows an embodiment of the subject matter of the invention, for example; it shows
Abb. ι eine Seitenansicht des Fal-ztrichters mit dem der Erfindung entsprechend ausgeführten Kreismesser undFig. Ι a side view of the former with the circular knife executed according to the invention and
Abb. 2 eine Endansicht zu Abb. 1, bei der die Trichterwalzen und das Querschneidwerk schematisch dargestellt sind.Fig. 2 is an end view of Fig. 1 in which the hopper rollers and the cross cutter are shown schematically.
Die übereinanderliegenden gedruckten Papierstränge α werden über die Leitwalze b zu dem Falztrichter c geführt, um durch die Walzen d, e und /, g zu dem Schneidzylinder h, i geführt zu werden, die das in der Längsmitte gefalzte Produkt quer schneiden und in Verbindung mit einem nicht dargestellten Falzzylinder auch quer falzen. Schräg oberhalb der Walze & ist das Kreismesser h gelagert, das von den Zahnrädern /, m gleich schnell wie die Walze b angetrieben wird und die Papierstränge in der Längsmitte schneidet.The superimposed printed paper strands α are guided over the guide roller b to the former c in order to be guided by the rollers d, e and /, g to the cutting cylinder h, i , which cut the product folded in the longitudinal center transversely and in connection with a folding cylinder, not shown, also fold transversely. The circular knife h is mounted diagonally above the roller &; it is driven by the gears /, m at the same speed as the roller b and cuts the paper strands in the longitudinal center.
Bei dem Ausführen der Erfindung erhalten die Walze & und das Kreismesser k den gleichen Durchmesser, der die Hälfte des Durchmessers des Plattenzylinders beträgt. An der Schneidkante dieses Kreismessers k ist ein Ausschnitt η vorgesehen, der die Papierstränge stellenweise ungeschnitten läßt, und zwar zweckmäßig an der Stelle, -wo nachher das Querschneiden durch die Zylinder h, i erfolgt. Diese Stelle ist in Abb. 1 durch die punktierte Linie 0 angedeutet. Diese Linie 0 teilt die ungeschnittene Strecke in zwei etwa gleich lange Teile, von denen der eine Teil nach dem Querfalzen des Produktes um die Linie p zu den vorderen Papierlagen und der andere Teil zu den hinteren Papierlagen gehört.In carrying out the invention, the roller & and the circular knife k are given the same diameter, which is half the diameter of the plate cylinder. At the cutting edge of this circular knife k a cutout η is provided which leaves the paper strands uncut in places, specifically at the point where the cylinders h, i are subsequently cut across. This point is indicated in Fig. 1 by the dotted line 0. This line 0 divides the uncut section into two parts of approximately equal length, one part of which belongs to the front paper layers after the cross-folding of the product around line p and the other part to the rear paper layers.
Bei der Anwendung der beschriebenen Vorrichtung bleiben daher die Zeitungen auf einer kurzen Länge an der oberen Kante vorn ungeschnitten und können nur in der Mitte der Papierlagen aufgeschlagen werden.When using the device described, therefore, the newspapers remain on one short length at the top edge uncut in front and can only be used in the middle of the paper layers are opened.
