Patent ID: 8636038

Claim:
An operating method of a reinforcing bar binding machine including a wire feed mechanism for feeding a wire from a wire reel rotatably disposed on a binding machine main body and a wire cutting mechanism for cutting the wire at a position between the wire reel and a portion of the wire wound around reinforcing bars after the wire has been fed and wound around the reinforcing bars, the operating method comprising: an initializing operation that includes: shutting off a wire passageway defined by a wire through hole in a cutting piece and by a wire shear port extending entirely through a cutter of the wire cutting mechanism by rotating the cutter around the cutting piece to misalign the wire shear port of the cutter from the wire through hole of cutting piece; feeding the wire by the wire feed mechanism while the wire passageway remains shut off; and deactivating the wire feed mechanism when a leading end of the wire butts against the cutter.
