  • the measurement beam path is interrupted by this product 2a, 2b. Accordingly, the light signal is not reflected to the sensor 72.
  • FIG. 7 2 shows, by way of example, how a drawn-on printed product 2a, which is transported away by a gripper 12 of the transfer run 10, covers the product gap 9 following in the transport direction F and thus covers the measuring beam path 74 of the light signal.
  • FIG. 8 2 shows by way of example how a so-called vagabond, redundant printed product 2b, which is transported away together with a printed product 2 of the same working cycle held properly by a gripper 12 of the takeover circulation 10, covers the product intermediate space 9 following in the transport direction F and thus covers the measuring beam path 74 of the light signal.
  • the controller 61 detects a malfunction, such as the presence of a surplus printed product 2b or a mounted printed product 2a.
  • the control device 61 can now initiate one or more of the steps already mentioned above, such as emergency stop, removal of the relevant printed product 2a, 2b or generation of a warning message.
  • further reflectors can be arranged on the carrier wheel 13, which can detect further process states within further measuring time windows in interaction with the light signal source 71 and the sensor 72.
  • a continuous reflector can be arranged, wherein in each case a reflector section is associated with a measuring time window of a power stroke.
