摘要： Apparatus for making electrical pins with frusto-conical end portions, comprises a wire feed station for the supply of a length of metal wire to a wire severing station at which a wire severing wheel severs the wire into pin blanks, in cooperation with a fixed bushing. The wheel pushes the blanks along a track to a pin blank rolling station at which the end portion of the pin blanks are rolled to frusto-conical shape between a pin rolling fixture and a pin rolling wheel having mounted for rotation relative thereto, a pin blank entraining ring having pin blank receiving grooves.
