Patent abstract
A strip-shaped supporting adhesive tape is joined to a ring frame, and then is stuck with a cutter blade such that the cutter blade penetrates the adhesive tape. In a state where a cutting edge of the cutter blade is brought into contact with a tape joined side of the ring frame, thereafter, the adhesive tape is cut along a contour of the ring frame while electric current is fed to each of the cutter blade and the ring frame. Herein, a sensor monitors a conduction status in real time.
