摘要： A blind rivet setting device which automatically feeds blind rivets into a rivet table (62), then sets the rivet (R) by pulling and detaching the mandrel (M). The rivet feed mechanism includes a thin strip or ribbon (150) of flexible material capable of holding the mandrel tips pierce/therethrough and evenly spaced apart. The strip (150) is drawn from a magazine (152a) for holding a quantity of blind rivets so connected to the strip (150) through a transverse feed slot (116) formed through the rivet table (62) generally orthogonal to the longitudinal axis of the device (10). A spring biased retracting device (156) continuously pulls the strip (150) through the feed slot (116) so that the next rivet in succession facing the rivet table (62) is automatically drawn into axial alignment within the rivet table (62) ready for positioning and setting into a work surface (W). A worn gear (132) with eccentric output (136) drives a connecting rod (138) for pulling and fracturing each mandrel (M) from the rivet body.
