Abstract

PURPOSE:To measure the length of a coiled strip with good accuracy by measuring coil diameters with lapse of time, and operating the length of the strip from the coil diameter change line obtained by analyzing these regressively. CONSTITUTION:The diameters of a wound coil are measured with lapse of time from the number of revolutions of a take-up reel 3 and the feed speed of a strip 4. The respective plots P of the coil diameter D'c is linearly regressively analyzed, whereby a change line A for coil diameters on the reel 3 is provided. The coil diameter D''c determined from this line A is applied to a prescribed operation equation, whereby the length of the strip is operated. According to this method, the length of the strip wound to the coil 2 is measured with good accuracy, and the coils which are made into products are controlled adequately.
