Abstract: A method of making an amorphous metal transformer core includes the steps of providing an amorphous metal core having two legs which are connected by an upper and a lower yoke, wrapping each of the legs with a sheet of flexible material which is capable of withstanding, without degradation, the temperature which is required to anneal the amorphous metal core, and then annealing the amorphous metal core. An amorphous metal transformer core includes a stack of amorphous metal laminations, the stack being formed into two legs which are connected by upper and lower yokes in which the legs are wrapped with a sheet of flexible material which is capable of withstanding, without degradation, the temperature required to anneal the amorphous metal core.

Abstract: Disclosed is a retaining band for the magnetic core loop of an electrical transformer. The retaining band includes a locking mechanism to hold it in place around the core. The locking is accomplished by overlapping the ends of the band, cutting a pair of incisions in the overlapping region which extend from the sides of the band inwardly, and then bending the resulting tab(s) inwardly. If desired, the tabs can be spot welded to provide added locking force.
