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.
La présente invention concerne une navette (11) pour l~alimentation en rivets tubulaires (12) de longueur axiale relativement faible par rapport au diamètre de leur tête, le long d~un tuyau souple (26), d~un outil d~installation de rivet déplaçable, présentant une ouverture (18) s~étendant parallèlement à l~axe sur toute sa longueur. À travers cette ouverture, un rivet peut être inséré dans la navette ou bien en être retiré. Celle-ci permet également de retirer latéralement de la navette un mandrin allongé sur l~extrémité duquel un rivet a été axialement amené. L~extérieur de la navette (11) et l~intérieur du tuyau (26) présentent une section transversale similaire qui forme un ajustement coulissant et coopèrent pour maintenir la navette (11) dans une relation prédéterminée avec le tuyau (26), afin de faciliter l~insertion et le retrait du rivet susmentionné.
