Abstract

The invention relates to a method of making a magnetic core from amorphous strip material for use in a transformer or similar electrical induction apparatus. In accordance with this method, a continuous strip of non-annealed amorphous metal is wound around a mandrel to form an initially round core which thereafter is clamped in a predetermined way and cut entirely through one transverse section thereof while a rust inhibiting liquid coolant is applied thereto. The resulting unconnected strips are then separated into a number of groups which are assembled together in a predetermined manner to form a substantially oval core. This core, in its final shape, is annealed and simultaneously subjected to a magnetic field of predetermined strength.
