Abstract
In a method and apparatus for cutting and welding slugs to lead wires, a die has a bore therein through which the slug feedstock is stepwise advanced. The die is ferromagnetic and a permanent magnet is positioned with one magnetic pole adjacent the cutting end of the die. A knife has an opening therein for receiving the feedstock advancing out of the die when the hole and die are aligned. Rocking of the knife cuts free a slug. When the knife is rocked back into alignment, the slug positions itself on the freshly cut end of the feedstock. Advance of the feedstock then pushes the slug out of the knife and presents it to a clamp.
