    Abstract: A wire guider includes a guiding unit having an inner path extending along the running direction of the wire to guide the running of the wire and an air supply unit for supplying air into the inner path to form a spiral air flow having a current rate faster than a running rate of the wire between an outer surface of the wire and an inner surface of the inner path. Wire Vibration resulting from a thrust force of mill rolls can be damped to more stably carry out one-direction running of the wire and minimize contact between the wire and a guide path. This reduces surface defects of the wire and abrasion of the guide system and protects a sensor unit from damage.
