Abstract
A laminated amorphous-metal transformer core having four sides joined by corner regions includes (a) joints located in a joint region in one of its sides and (b) side portions between the joint region and two corner regions. After annealing the core and while restraining the core laminations in a core region remote from the joint region, the joints are separated by displacing each of the side portions into a position of approximate alignment with the side of the core interconnected therewith at a corner region. Then a splint is applied to each of the side portions and the aligned interconnected side, thus holding these two parts in approximately aligned relation. The splint is relied upon to facilitate insertion of the aligned parts into the window of a coil, following which the splint is slid off the aligned parts, and core-lacing is completed.
