ABSTRACT:
A method and machine for making screw-on connectors is disclosed. The connectors have an insulating shell with a bore open at one end and a wire coil in the bore of the shell. The method includes the steps of heating the coils sufficiently so that it in turn heats the bore of the shell in contact with it to soften the interior of the bore, and applying a compressive axial thrust between the shell and coil while the interior of the bore is still soft to force them together to a predetermined axial relation. A suitable machine for accomplishing the steps of this method is also disclosed.
