  "abstract": "The present invention relates to a security system ( 10 ) for securing a restricted access area in a converting machine. The security system ( 10 ) comprises a detection unit ( 20 ) comprising a plurality of sensors ( 22 ) arranged side by side an having a vertical sensing direction. Each sensor has an individual control zone (Z). The detection unit is configured to detect control signals ( 23 ) indicating an arrival time (t 1 ) and a departure time (t 2 ) of an object ( 24, 32 ) transported through each of the control zones. The security system further comprises an evaluation unit ( 26 ) configured to receive the control signals ( 23 ) from the detection unit and a memory ( 25 ) containing a program to cause the evaluation unit to determine an error state indicating the presence of a prohibited access based on the control signals ( 23 ).",
