<p>A shuttle (11) for feeding tubular rivets (12), which are of relatively short axial length compared with their head diameter, along a flexible hose (26) to a movable rivet- installation tool has an aperture (18) running parallel to its axis along its whole length. Through this aperture a rivet can be both inserted into, and removed from, the shuttle. It also enables the sideways removal from the shuttle of an elongated mandrel, over the end of which a rivet has been axially fed. The exterior of the shuttle (11) and the interior of the hose (26) have similar cross-sections, which are a sliding fit and which co-operate with each other to maintain the shuttle (11) in a pre-determined rotational relationship with the hose (26), to facilitate insertion and removal of the rivet as aforesaid.</p> |
