Abstract
Fastener installation apparatus for operating cylically so as to instal successively a plurality of fasteners of the type in which a portion is broken off at installation (e.g. breakstem blind rivets) comprises a fastener installation head (11) and a pipe (31) for conveying the broken-off portions away from the head to a receptacle (15). Detection device (48) is mounted adjacent the pipe (31) to detect the presence of a broken-off fastener portion at a pre-determined position (58) there along near the receptacle (15). When a portion is thus sensed, an electrical signal is sent by the detection device (48), via a relay (51), to the installation control system (14a, 14b), so as to allow cyclical operation of the system to continue.
