Abstract: A method for manufacture of lamp bulbs wherein four wires are arranged in parallel with and spaced apart by a suitable distance from each other and supported by a plurality of glass beads which are melted when the wires are attached. Two inner wires of the four wires are cut off at predetermined points and bent at cutout ends whereby lead and anchor wires are provided whereas the two outer wires are bent to form frame wires, whereby a filament-supporting assembly is provided; thereafter filaments are supported between the lead wires of the filament supporting assembly and engaged with the anchor wire; the filament-supporting assembly with the filaments supported thereon is placed into a glass envelope; the envelope is evacuated and sealed; and a base is attached to the envelope.
