Abstract
With rapidly-operating packaging machines for cigarette packages, monitoring of blanks is becoming increasingly necessary, such a system supervising the feed of correct blanks in the correct relative position. The same applies to monitoring systems for revenue seals. In the method according to the invention for monitoring blanks or revenue seals with the aid of a sensor, contours of an edge and of a surface of the blank or of the revenue seal are scanned. Pulses obtained thus are compared with a reference value by an evaluating unit.
