Claims (1)

[Scope of claim for utility model registration] Chain-like component winding in which the chain-like component is rewound from a component reel in which interlayer paper and chain-like components are overlapped and wound, and the unwound interlayer paper is then wound onto the interlayer paper reel. The return device includes a motor with a constant rotational torque that rotates the interlayer paper leak, a pulse generating means driven by the rotation of the motor, and a pulse generating means that generates pulses within a predetermined period when the number of pulses from the pulse generating means exceeds a predetermined value. An interlayer paper break detector for a chained component rewinding device, comprising: a logic circuit that detects when the interlayer paper has run out and outputs a determination that the interlayer paper is out.
