Description
und 7 paarweise und versetzt zueinander angeordnet. Die Abtaseinrichtungen 6, 7 sind an Haltern 8, 9 befestigt, die ihrerseits im wesentlichen in der Höhe verstellbar an den Maschinenseitenwänden 15 angeordnet sind.and 7 arranged in pairs and offset from one another. The scanning devices 6, 7 are attached to holders 8, 9, which in turn are arranged on the machine side walls 15 so as to be essentially adjustable in height are.
Aus der F i g. 2 ist der Verlauf der Lichtstrahlen der Abtasteinrichtungen 6, 7 ersichtlich, die vorzugsweise, wie aus F i g. 1 hervorgeht, unter einem Winkel von etwas weniger als 90° zur Bahn geneigt angeordnet sind. Jede Abtasteinrichtung besteht in bekannter Weise aus einer Lichtquelle 10 bzw. 10' und einem auf der gegenüberliegenden Bahnkante angeordneten lichtempfindlichen Empfänger 11 bzw. 11'. Lichtquelle und lichtempfindlicher Empfänger sind dabei nicht auf einer zur Bahnebene parallelen Linie, sondern höhenversetzt angeordnet. Die beiden Lichtstrahlen eines Paares verlaufen demnach in der Vorderansicht überkreuz unter einem flachen Winkel zueinander, wobei die Lichtquelle der benachbarten Abtasteinrichtung sowohl auf der gleichen Seite als auch auf der gegenüberliegenden Seite ebenso wie der lichtempfindliche Empfänger angeordnet sein kann. Diese sich kreuzende Anordnung der Lichtstrahlen soll verhindern, daß die Einrichtung nicht anspricht, wenn sich der Bogen seitwärts parallel zu einem der Lichtstrahlen hochhebt, er wird dann immer noch vom benachbarten Lichtstrahl getroffen, wodurch in bekannter Weise das Abschalten auf elektronischem Wege erfolgt. Da nicht voraussehbar ist, in welcher Richtung die Bahn beim Bruch abgelenkt wird, sind unterhalb derselben in der gleichen Weise wirkende Abtasteinrichtungen 7 angeordnet, deren Lichtquellen und lichtempfindliche Empfänger ebenfalls in unterschiedlichem Abstand von der Bahnebene befestigt sind.From FIG. 2 shows the course of the light beams of the scanning devices 6, 7, which preferably, as shown in FIG. 1 it can be seen, are arranged inclined at an angle of slightly less than 90 ° to the web. Each scanning device consists in a known manner of a light source 10 or 10 'and a light-sensitive receiver 11 or 11' arranged on the opposite web edge. The light source and the light-sensitive receiver are not arranged on a line parallel to the plane of the web, but offset in height. The two light beams of a pair therefore cross at a flat angle to one another in the front view, whereby the light source of the adjacent scanning device can be arranged on the same side as well as on the opposite side, as can the light-sensitive receiver. This crossing arrangement of the light beams is intended to prevent the device from not responding when the sheet rises sideways parallel to one of the light beams; it is then still hit by the adjacent light beam, which in a known manner switches off electronically. Since it cannot be foreseen in which direction the web will be deflected upon breakage, scanning devices 7, which act in the same way and whose light sources and light-sensitive receivers are also attached at different distances from the plane of the web, are arranged below the same.
Die Halter 8, 9 für die Abtasteinrichtungen 6, 7 sind mit Längslöchern 12, 13 versehen, um ein Verschieben der Abtasteinrichtungen mit den Haltern gegenüber der Papierbahn 3 zu ermöglichen. Außerdem sind die Lichtquellen 10 und die lichtempfindlichen Empfänger 11 schwenkbar an den Haltern 8, 9 befestigt, wie bei 14 angedeutet ist, um das Einstellen der Lichtquellen 10 zu den lichtempfindlichen Empfängern 11 bzw. 11' zu ermöglichen.The holders 8, 9 for the scanning devices 6, 7 are provided with longitudinal holes 12, 13 to allow displacement to enable the scanning devices with the holders opposite the paper web 3. aside from that the light sources 10 and the light-sensitive receivers 11 are pivotable on the holders 8, 9 attached, as indicated at 14, in order to adjust the light sources 10 to the light-sensitive receivers 11 or 11 'to enable.
Die Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt. Es ist im Rahmen derselben denkbar, auch Abtasteinrichtungen zu verwenden, bei denen jeweils eine oder beide Lichtquelle(n) und ein oder beide lichtempfindlichen Empfänger in einem Gehäuse untergebracht sind und mit einer ähnlichen an der gegenüberliegenden Papierbahnlängskante zusammenarbeiten. Außerdem können Lichtquelle und lichtempfindlicher Empfänger zur Papierbahnebene höhenversetzt und zugleich in Laufrichtung verschoben zueinander angeordnet sein.The invention is not restricted to the exemplary embodiment shown. It's under the same It is also conceivable to use scanning devices in which one or both light source (s) and one or both photosensitive receivers are housed in a housing and with a similar work together on the opposite longitudinal edge of the paper web. Also can Light source and light-sensitive receiver offset in height from the plane of the paper web and at the same time in Be arranged shifted to each other running direction.
