ABSTRACT:
A method of connecting a wire segment, such as a stator coil lead, to a terminal having a tang and severing the wire segment at the terminal including the steps of gripping the wire segment by gripper jaws of an industrial robot, manipulating the gripper jaws to lay the wire segment between one side of the tang and the adjacent face of the terminal, loop the wire segment around an edge of the tang, extend it past the tang, bend it over an edge of the terminal, and pull it with sufficient force that it stretches and breaks at a corner of the terminal edge. The wire segment is initially gripped with a sufficiently low pressure that it can slide along the gripper jaws as it is being manipulated to connect the wire to the terminal. The gripping pressure is increased prior to the pulling step so that sufficient pressure is applied that the free end of the wire segment is held clamped and will not be drawn through the gripper jaws when the wire segment is being stretched and severed.
