Abstract: An automatic assembly system for assembly of transformer laminated cores of the type having three parallel legs and two yokes. The laminations are stacked in a simple or complex configuration on a movable support frame on tracks, which receives the core laminations at a lamination loading station from four movable platforms on independent tracks. The platforms are grouped circumferentially about the support frame at four lamination feed positions while it is at the lamination loading station and have thereon stacked corresponding core laminations that are to be stacked on the support frame in a proper sequence and position order for forming a transformer laminated core. The system has four travelling gantry cranes that are on independent tracks and are each provided with a pick-up frame having suction cups arranged thereon for lifting the laminations individually from corresponding platforms at the four lamination feed positions and depositing them on the support frame in a properly stacked relationship.

Abstract: The welding of the body and of the ring with the distributor of a steam turbine diaphragm is carried out in four different areas holding an assembly, formed by two semi-diaphragms, in a substantially vertical position, at most tilted a few degrees off vertical, while four welding units operate simultaneously, two for each face of the assembly, providing for each assembly face to be suitably heated. Two supports are provided, one movable in respect to the other for positioning and handling of the assembly to be treated. Provision is made for vertically adjusting the assembly position with respect to a referring surface, so that the area on which each welding unit works is always on the same level, whatever the dimensions of the assembly to be welded. Provision is also made for heating and insulating both the assembly faces.
