First Claim
Patent Images
1. A process for the manufacture of a transformer comprising at least a laminated transformer core having at least one transformer leg and at least one laceable joint, said transformer further comprising at least one transformer coil which process comprises the steps of:
- affixing a support to portions of at least the one transformer leg;
laying the support and the transformer core onto a stage in a generally horizontal orientation;
inserting the at least one transformer coil onto the at least one transformer leg;
reconstituting the transformer core; and
withdrawing the stage from the interior of the at least one transformer coil.
