Figure 5.6: Hole recognition
For hole recognition within a web material, a beam area must be defined over the area to be monitored
and mapped to an output. All beams in this area are interrupted. If a beam becomes “free” due to a flaw
in the material, the output switches.
If, for example, the web edge wanders slightly, the beam area can be dynamically adapted by “tracking”
the start beam by selecting the
First interrupted beam (FIB)
evaluation function and the end beam by
selecting the
Last interrupted beam (LIB)
evaluation function.
