た。However, in the case of the former, the stop position at the tip of the coil is caused by visual stop.
Is not constant, and the cradle roll presses too much weight on the coil to cause wrinkles.Wrinkles may cause inconsistencies in the joining position when joining the end of the preceding coil, and other inconveniences. In the case of a coil, static electricity is generated, causing various problems.

トに定位置に止められない課題があった。In the latter case, as shown by the alternate long and short dash line in FIG. 4 , in the case of a thin coil, when it is drooped, the tip portion meanders to form irregularities on the surface of the coil, which makes it impossible to measure the dimensions accurately. However, if there is a large difference between the coil diameters, the reflected light may not be caught, and there is a problem that the light cannot be constantly stopped at a fixed position.

The phototube is placed below the payoff reel that rotates forward and backward, and the payoff reel is turned on until the tip of the coil crosses the phototube.
Rotate the freele in the rewinding direction and wind it after passing .
Is rotated in the direction taken to develop the coil-fore-end fixed-position stop method characterized by feeding a length L + 90 ° winding direction to <br/> rotation from the position of the phototube to the horizontal axis of the pay-off reel, adopted .
