Abstract
In the manufacture of a capsule for a sealed beam lamp or vehicle headlight, two coiled filaments on lead-in wires are supported in a holder with sufficient rigidity to accurately maintain a predetermined spacing between the filaments during a subsequent press sealing operation. The filaments are then inserted into an open-ended glass tube and the open end is press sealed onto the filament lead-in wires at the same time that wire supports are embedded in the press seal. The wire supports are then connected to mounting rods in the finished capsule.
