When the fin falls on the lower contact plate 5, the fin conductor reduces the voltage difference between the rotating shaft 3 and the lower contact plate 5, activates the voltage difference detector 7, and notifies the time relay 8 to start. After receiving the signal for a certain period of time, the time relay 8 starts the material receiving drive structure to wind when the fins on the production line are fed in a sufficient amount.
