Claim 9:
10. A nose arrangement for a self-piercing rivet setting tool having a punch for setting self-piercing rivets, the nose arrangement comprising:
a self-piercing rivet escapement mechanism that is disposed laterally with respect to the punch, the self-piercing rivet escapement mechanism comprising:
a self-piercing rivet track in which the self-piercing rivets are receivable; and
a first resiliently biased jaw that is disposed towards or at an end of the self-piercing rivet track, wherein the first resiliently biased jaw is biased towards a closed configuration in which the first resiliently biased jaw is configured to retain self-piercing rivets in the self-piercing rivet track;
wherein the first resiliently biased jaw is biased towards the closed configuration by a biasing force that acts in a direction that is generally parallel to the self-piercing rivet track;
wherein the first resiliently biased jaw is moveable to an open configuration in which a self-piercing rivet can escape the self-piercing rivet track;
wherein the first resiliently biased jaw comprises a first cam surface that faces away from the self-piercing rivet track;

the nose arrangement further comprising:
a transfer mechanism for transferring the self-piercing rivets from the self-piercing rivet escapement mechanism to under the punch, the transfer mechanism comprising a moveable member that can be moved between a first configuration and a second configuration and is configured to hold at least one self-piercing rivet;
wherein, in the first configuration, the moveable member exerts a load upon the first cam surface of the first resiliently biased jaw of the escapement mechanism such that the first resiliently biased jaw moves to the open configuration such that a self-piercing rivet escapes the self-piercing rivet track and passes to the moveable member.
