Abstract: A coil having several turns of an insulated conductor is provided with a shrinkage tube of insulating material by producing such relative movement between the conductor and the tube that the end of the conductor passes into the tube and through it a number of times until a portion of all the coil turns is enclosed within the tube. The tube, which may be corrugated to shorten its length during the winding operation, is then heated beginning at one end and expands along and contracts over the wound coil.
