A METHOD OF ELECTRICALLY INSULATING AND ELECTRICAL DEVICE HAVING A BORE AND SLOTS OPENING THEREFROM, COMPRISING THE STEPS OF POSITIONING A FORMING BLADE IN THE BORE OF THE DEVICE, PLACING A ROLL OF ELECTRICAL INSULATING TAPE IN THE BORE OF THE DEVICE WITH AN END PORTION OF THE TAPE POSITIONED BETWEEN THE BLADE AND THE OPENING FROM THE BORE INTO ONE OF THE SLOTS; MOVING THE BLADE THROUGH THE OPENING INTO SAID ONE SLOT AND THEREBY PRESSING A PORTION OF SAID TAPE INTO SAID ONE SLOT BY SAID BLADE, THEN ROTATING BLADE SO AS TO FORM THE PORTION OF THE INSULATING TAPE IN SAID ONE SLOT INTO A SUSBSTANTIALLY CIRCULAR LOOP, AND MOVING THE BLADE FROM SAID ONE SLOT THROUGH THE OPENING THEREOF INTO THE BORE OF THE DEVICE; THEREAFTER MOVING THE BLADE FROM THE BORE THROUGH THE OPENING INTO A SUCCEEDING SLOT OF THE DEVICE AND THEREBY PRESSING ANOTHER PORTION OF SAID TAPE INTO SAID SUCCEEDING SLOT BY SAID BLADE, THEN ROTATING THE BLADE TO FORM THE PORTION OF THE INSULATING TAPE IN SAID SUCCEEDING SLOT INTO ANOTHER SUBSTANTIALLY CIRCULAR LOOP, AND MOVING THE BLADE FROM SAID SUCCEEDING SLOT THROUGH THE OPENING THEREOF INTO THE BORE OF THE DEVICE; AND THEREAFTER PRESSING OTHER PORTIONS OF THE INSULATING TAPE INTO EACH OF THE SUCCEEDING SLOTS OF THE DEVICE BY REPEATING THE THREE LAST-MENTIONED STEPS UNTIL A CONTINUOUS STRIP OF THE INSULATING TAPE HAS BEEN INSERTED IN ALL OF THE SLOTS OPENING FROM THE BORE OF THE DEVICE AND FORMED INTO A PLURALITY OF SUBSTANTIALLY CIRCULAR LOOPS.
