Abstract

PURPOSE:To untouchingly restrict the swing of a steel strip to be coated without necessity of arranging any guide means, by arranging a magnetic means, which can apply a transverse outward tensile force onto the steel strip, near a coating metal adhesion amount-controlling device. CONSTITUTION:The steel strip 1 raised from a hot-dip coating metal bath 3 passes through a coating metal adhesion amount-controlling device 5. At this time, a magnetic means 6a attached to a swing stopper 6 arranged near the device 5 applies an outward tensile force onto the steel strip 1. A gap sensor 6d attached to the end of the magnetic means 6a measures a distance between the magnetic pole 6b of the magnetic means 6a and the edge of the steel strip 1. A signal representing the measured distance is inputted into a comparater 6e, where the signal is compared with a preset value. When a deviation is generated, the magnetic means 6a is carried to a position, where the deviation becomes zero, through a screw rod 6i and a support member 6 by its differential signal. Consequently, the transverse outward tensile force to be applied onto the steel strip 1 can be maintained at a fixed level.
