Machine for punching out electronic circuitry parts, method for replacing tape supply reels, and method for producing electronic circuitry parts from tape

摘要

Carrier tapes, each carrying electronic circuitry parts at predetermined intervals on a carrier portion, are successively and continuously fed to a punching station from a tape feeding station with at least a pair of tape supply reels. While a carrier tape from a first supply reel is being fed to the punching station, a carrier tape from a second supply reel is set in a standby position. As soon as the carrier tape from the first supply reel is consumed to a last electronic part, a head end of the carrier tape from the second supply reel is spliced to a tail end of the carrier tape of the first supply reel by means of tape holder members located in the course of a tape supply route between the tape feeding station and the tape punching station, thereby make replacement of the tape supply reel quicker and easier.
