SELF-ADJUSTING HEAD

摘要

A system for installing fasteners (20) in a panel (22) and automatically sensing and compensating for certain error conditions which commonly arise in the installation process. The system monitors the load exerted during the installation process and compares the exerted load to nominal load values. If an error results between the two load values, appropriate corrective action is taken. If there is no corrective action which can be initiated to rectify the error condition, the system is halted.
