ABSTRACT:
The wrapped insulation of coils of large electric machines--motors or generators--is set by heat and pressure in a press that extends the length of both wrapped legs of the coil and supports the coil so that it is substantially free from stress. The coil may be supported with its wrapped legs level and horizontal, and the press can be adjustable for different coil sizes and configurations. The heat and pressure cycle is operable automatically to suit the requirements of the insulating material.
