To make it least necessary to interrupt the operation of a cutting apparatus 11. Whether there is a prefeeder stop cause which requires a prefeeder 120 to be stopped is detected during wire processing. Upon detecting the prefeeder stop cause, the prefeeder 120 is stopped and the operation of the cutting apparatus 11 is continued by changing a length R of a pass line PH. Even if wire processing is to be hindered unless the prefeeder 120 is stopped in the case that the kind of a wire W is changed, the wire W is entangled or a wire joint is disconnected, the cutting apparatus 11 needs not be immediately stopped, thereby making it least necessary to interrupt the operation of the cutting apparatus 11.
