Continuous riveter

A continuous riveter comprising:

• a chuck cylinder;
• a nose piston inserted to the chuck cylinder so as to be movable vertically, and provided at its lower end with an elongated cylinder;
• a jaw case piston to which a jaw case is fixed, the jaw case moving vertically within the cylinder;
• a jaw, internally inserted to a lower end of the jaw case and engageable and disengageable with and from a tapered surface on an internal lower end of the jaw case, for holding and releasing a shank of a blind rivet;
• a jaw pusher elastically biased to abut against a top of the jaw;
• a nose piston which is disposed at a lower end of the cylinder, and to which the shank of the blind rivet is to be inserted;
• and
• a rivet supply section including:
• an accommodation case for accommodating therein a web-like blind rivet holder in a wound state the blind rivet being attached to the blind rivet holder;
• and
• a tape air cylinder for supplying the blind rivet attached to the blind rivet holder along a guide plate one by one,
• wherein the guide plate is elongated from the accommodation case of the rivet supply section, and includes a linear feed section of a predetermined length and a bent section inclined at a predetermined angle with respect to the linear feed section, whereby a perpendicular section of the blind rivet holder is bent along the bent section, after being passed through the linear feed section of a predetermined length there along,
• a pressing plate is provided, for pressing and guiding the perpendicular section of the blind rivet holder, along the guide face from the linear feed section to the bent section of the guide plate, whereby the blind rivet holder sent out linearly by a feeding claw that reciprocatingly linearly moves by means of the tape air cylinder, is guided from the linear feed section to the bent section, and is then bent there along due to the pressing plate, and
• wherein the cylinder of the nose piston is disposed on a shank of a blind rivet held by an upper tab and a lower tab of the blind rivet holder immediately after the blind rivet holder has been passed through the linear feed section of the guide plate and has been bent at the bent section, so that the axis of the shank of the blind rivet coincides with the axis of the cylinder.
