Abstract (en)
[origin: EP2093173A1] The device has a sensor element i.e. complementary metal oxide semiconductor (CMOS) matrix sensor, for registering a sensor zone (308) on material webs (300, 300', 300''). The material webs operate on a predetermined material web level in a predetermined travel direction. A light transmitter (330) i.e. laser, produces light beam spots (334, 334', 335, 335') on the material webs, where the device determines a position of a deviating material web level that deviates from the predetermined material web level based on the light beam spots. Independent claims are also included for the following: (1) a material web orientation feature detecting method (2) a material web orientation feature detecting system comprising a roller subsystem.
