ABSTRACT:
A transport-by-suction type die for use in a working machine having working stages, the die comprises a feed arm mounted in a position above the working stage in a lower part of the die to be slidable in the direction of consecutive feed and to be vertically movable with respect to a surface of the working stage; suction pads for supporting a piece part by suction, the suction pads being attached to the feed arm at the same interval as that of the working stages; a negative-pressure aspiration mechanism connected with each of the suction pads; and a drive control mechanism for causing the feed arm to move vertically and reciprocate in synchronism with working processes.
