摘要： A blind riveting tool head for placing blind breakstem rivets is provided with a stem-disposal device which comprises a flexible hose connected to the rear end of a passage running rearwardly through the head from the rivet-placing jaws. An air injector at the junction of the head and the hose supplies both a flow of air rearwardly along the hose to assist broken-off stem portions rearwardly therealong, and also a flow of air forwardly along the passage through the head. When the tool head is operated to place a rivet, both airflows are shut off as the rivet-placing jaws approach their rearmost position, and thereafter the rearward airflow along the hose is re-established before the forwards airflow along the passage.

摘要： In a blind riveting machine, in which a mandrel having a head is pulled downwardly by reciprocable and openable pulling jaws to draw the mandrel head through the bore of a tubular rivet supported at a setting station by normally closed, openable nose jaws, the nose jaws have yieldable detent means for resisting upward movement of the mandrel, and a reciprocable tube concentric with the mandrel for lifting further rivets along the mandrel, past the opened pulling jaws and nose jaws, to the setting station, has a spring detent which becomes frictionally engaged with the mandrel whereby the mandrel after being lifted with the rivets can be pulled downwardly again so that its head abuts the rivet at the setting station, thereby accurately adjusting the position of the mandrel relative to the pulling jaws, before the pulling jaws again grip the mandrel, in dependence upon the actual size of the rivet next to be set.
