ABSTRACT:
In manufacturing an electric lamp having at least one current supply wire connected to a lamp cap after having been passed through an aperture in the cap, the end of the wire is guided through the aperture after folding back the free end of the wire to provide a rounded surface which does not snag. Preferably the wire is folded back at a predetermined distance from its point of emergence from the lamp envelope, thereby eliminating the need for snipping off the excess length.
