Continuous riveting method for fastening blind rivets

A continuous riveting method for fastening conventional blind rivets, each mounted in sequence by a pair of tabs with each blind rivet in generally spaced parallel relationship to each other on a continuous carrier, comprising the steps of:

• positioning a blind rivet having a head and an elongate stem into alignment with a hole in a workpiece to be riveted at a riveting station embodying a nose piece having an elastic ring, and jaws having through in-line apertures;
• placing the blind rivet gripped by said jaws into said hole with said head abutting against said workpiece and said stem extending along a direction generally away from said workpiece;
• initially pulling said stem:substantially along said direction while maintaining said head of said rivet against said workpiece to effect riveting action,
• further tearing and pulling said stem so as to separate a remaining torn stem core from said blind rivet;
• releasing and directing said torn stem core into a torn stem core storage compartment and maintaining said blind rivet in place with said elastic ring, and bending said pair of tabs as said nose piece and jaws descend, and releasing said torn stem core while vacuuming said torn stem core storage compartment for pulling in and receiving and storing a plurality of said torn stem cores;
• and clearing said riveting station so as to allow a further blind rivet to be prepared for riveting.
