Abstract

Die Erfindung betrifft einen Fehlbogensensor (10) einer Druckbogen verarbeitenden Maschine, insbesondere einer Bogendruckmaschine, mit einer Sendeeinrichtung (12), die auf einen zu überwachenden Bereich einer Druckbogentransportbahn einen insbesondere optischen Prüfstrahl (13) richtet, und mit einer Empfangseinrichtung (17), die den Prüfstrahl oder den an einer Reflektoreinrichtung (14) zu reflektierenden Prüfstrahl (13) als Reflektionsstrahl (16) nur dann empfängt, wenn im zu überwachenden Bereich der Druckbogentransportbahn kein Druckbogen vorhanden ist. Erfindungsgemäß trifft der Prüfstrahl (13) und/oder der Reflektionsstrahl (16) dann, wenn im zu überwachenden Bereich der Druckbogentransportbahn ein Druckbogen vorhanden ist, auf eine Druckbogenoberfläche mit einem spitzen Winkel von maximal 5° auf.

Figure imgaf001
The invention relates to a false - sheet sensor (10) of a sheet - fed processing machine, in particular a sheetfed press, having a transmitting device (12) which directs a particular optical test beam (13) onto a region of a printing sheet transport path to be monitored, and a receiving device (17) only receives the test beam or the test beam (13) to be reflected at a reflector device (14) as a reflection beam (16) if no printed sheet is present in the region of the printed-sheet transport path to be monitored. According to the invention, the test beam (13) and / or the reflection beam (16) strike a printed-sheet surface at an acute angle of at most 5 ° when there is a printed sheet in the area of the printed-sheet transport path to be monitored.
