ABSTRACT:
Electrical lamp sockets are moulded on and around elongated mutually insulated conductors to which the socket contacts are connected before moulding; the contacts being firmly embedded in the socket material. A transfer turntable carries a plurality of supports for mounting the socket contacts in spaced relation thereon; each support being successively brought to a moulding station and co-operation with mould elements to form a mould for the socket. The conductors are entrained through the moulding station and impaled on points of the contacts at said station prior to fully closing the mould and injecting the moulding charge.
