Precise detection of web edges or line marks.

Precise detection of web edges or line marks.
Detectors can be basically divided into optical reflection types,optical transmission types and ultrasonic transmission types. Reflection type detectors are generally used in the detection of line marks and the detection of pattern edges is also possible. Transmission type detectors are mainly used in the detection of web edges,and some modeles can detect line marks.
