Abstract

PURPOSE:To prevent the damaging of a tape by detecting the rotation of a reel, deciding that it is abnormal when the number of upper limited rotations is exceeded, braking the reel, stopping the drum, operating simultaneously a supplying side reel and a winding side, and unloading them. CONSTITUTION:When a condition 6, in which a tape 8 is wound to a drum 1 due to dewing, etc., is caused a reel 2 is quickly changed from the normal rotation of an arrow 9 to the abnormally fast rotation of an arrow 10. A pulse generating circuit to detect the reel 2 and its rotation is provided, it is detected that the rotation is faster than a prescribed value, the reel braking is operated and the drum 1 is stopped. After the tape 8 is stopped, both supplying side reel 2 and winding side reel 3 are rotated in a tape winding direction while the rotation of the drum 1 is stopped, and thus, the sticking to an upper drum and a lower drum of the tape is separated, and unloading can be executed without damaging the tape.
