PURPOSE:To maintain the packing rate of a flux constant by determining the theoretical value of a flux mass from the size factor and specific gravity of a belt-like wire and controlling the feeding out rate of the flux so as to decrease the deviation between said value and the current value of the flux mass. CONSTITUTION:The length, width and current length of a belt-like wire 2a are measured at all times with a mass detector 6 and are fed to a control device 7 which calculates the current value of the mass per prescribed length of the wire 2a from the same and the specific gravity of the wire 2a and calculates the theoretical value Mfk of the flux mass corresponding to said value as a max. target value. On the other hand, the feeding out rate of the flux (the current value of the mass) Mfa which is supplied currently onto the wire 2a from the feeding out part 8a of an electromagnetic feeder 8 is measured and is fed at all times to the device 7. The arithmetic processing of (Mfa-Mfk) is performed in the device 7 to determine a deviation value + or -DELTAMf, and the supply rate of the flux from the feeder 8 is so controlled as to maintain the value DELTAMf within the prescribed value. |
