Claim 13:
14. A method of preparing self-piercing rivets for a setting operation in a self-piercing rivet setting tool having a punch for setting the self-piercing rivets, the method comprising:
providing a self-piercing rivet to a self-piercing rivet track of an escapement mechanism;
biasing a resiliently biased jaw of the escapement mechanism towards a closed configuration using a biasing force that acts in a direction that is generally parallel to the self-piercing rivet track;
wherein the resiliently biased jaw comprises a first cam surface that faces away from the self-piercing rivet track;
retaining the self-piercing rivet in the self-piercing rivet track using the resiliently biased jaw of the escapement mechanism; and
exerting, with a moveable member of the self-piercing rivet setting tool, a load upon the first cam surface of the resiliently biased jaw such that the resiliently biased jaw moves to an open configuration and simultaneously transferring the self-piercing rivet from the self-piercing rivet track to the moveable member for engagement by the punch.
