ABSTRACT:
The induction coil of this invention is wrapped on a non-metallic core with convolutions of the coil adjacent to one another. An adhesive tape is applied over the convolutions with a lapped seam of the tape and with the tape preferably extending beyond both ends of the coil in order to hold the convolutions of coil against moving with respect to one another while the coil is being transported from the winding step to the next operation in which a jacket is molded over the coil in a cavity of an injection molding machine.
