ABSTRACT:
A tool for setting blind rivets. The load of the motor which drives the pulling head between fully forward and retracted positions is monitored. When the pulling head is displaced to set a rivet motor direction will be changed if a moderate load is not sensed in a short period of time or if following such sensing of a moderate load the sensed low drops to a minimum value. When the pulling head is displaced in the opposite direction a stop will be engaged at the fully forward position and the sensing of a moderate load will stop the motor.
