PURPOSE:To improve quality control and production efficiency by measuring the feeding length per single rotation of winder to calculate the residual turn then comparing with the setting diameter at which the winder should be stopped thereby enabling automatic stoppage at predetermined position even for such coil as having unknown turn. CONSTITUTION:A coil having unknown turn is mounted onto a feeding machine 1 then rolled through a roller 2 and wound through a winder 3. Here, rotation detectors 4 are fixed to the feeding machine 1 and the winder 3 while a pulse generator 5 for detecting the feeding length L is provided. Upon start of operation, a pulse corresponding with the feeding length L of material per single rotation of winder 1 is counted through a counter to compare between said count and piD setting level. It is repeated for every rotation of winder and upon matching between piD setting level and the count or achieving desired winding diameter with desired thickness, a stop signal is provided to stop the operation of roller automatically resulting in improvement of quality.
