ABSTRACT:
A coil placing machine having an improved operating sequence for positioning prewound coils and coil separating insulators in certain core slots is disclosed. A portion of each insulator is supported obliquely to the core axis and then both insulators and coils are moved toward the core, coil movement is interrupted while the insulators continue to move into their ultimate position within the core and thereafter coil movement is resumed to complete the coil and insulator placing operation. In the preferred aparatus a conventional coil stripper and insulation inserting gauge and blade alignment tool are separately actuated to pass into the core so that the axial separation between the stripper and tool is at first constant and then increases and finally decreases as the coil and insulator insertion progresses.
