Abstract

PURPOSE:To improve measuring accuracy by varying a limit value for correcting a coil diameter increase portion operating value, based on the rotating speed of a winder, the plate thickness of a strip, etc. CONSTITUTION:A coil diameter DN of a sampling time is calculated by an arithmetic unit 3 from a rotating speed N of a winder and a strip running speed V, and a coil diameter increase portion correcting value DELTADN' is calculated by a limiter 6 from a coil diameter increase portion DELTADN of a sampling period and a limit value K. Subsequently, a coil diameter of the time of measurement is calculated by an arithmetic unit 9 from said correcting value DELTADN' and an initial value D0 of the winder. In that case, based on the speed N and the actually measured plate thickness (h) of a strip, the limit value K is calculated by a limit value arithmetic unit 14, and sent out to the device 6.
