Abstract

A stator coil lacing machine apparatus and method which enables the end windings of a stator to be bound together by lacing cord and which automatically ties a knot in the cord at the completion of the cycle to firmly secure the lacing cord in position. This method and apparatus reduces the direct labor necessary to produce the end windings and provides them in an automated and efficient manner. The lacing cord end securing knot is provided through a control system which actuates a lacing needle and cord supply tube which, with cord cutting hot wires and cord grasping jaws, interact to form a knot at the completion of the lacing cycle.
