(54) Bag binding machine


(57) A press-bonding device (6) is constituted by a base plate (27), a release plate (28), a die plate (29) and a press plate (30), and a downward ultrasonic type oscillator (30a) is provided in a tip portion of the press plate. The four plates carries out one cycle for descending and ascending through the longitudinal reciprocating motion of a shifter (31), and a binding piece is inserted and interposed between the base plate and the die plate with right and left leg portions overlapped so that a dowel is formed by means of a punch and a hole. Then, the press plate descends and the tip end face of the ultrasonic type oscillator comes in contact with the dowel of the binding piece (9) so that the two leg portions of the binding piece are welded.
