Abstract
The system includes means for moving a rivet or a collar from a storage bin to an initial position for the respective gripping assemblies. The presence of the rivet and/or collar is recognized as it moves through a feeding mechanism. After the rivet or collar is gripped, they are moved either into an opening in the workpiece, in the case of a rivet, or onto the tail of a lockbolt, in the case of a collar. The gripping assembly is then released from the rivet or the collar, with the gripping means moving back to an initial position. Further operations can then be carried out on the rivet or collar.
