Abstract
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.
