ABSTRACT:
A boxed and encapsulated rolled metallized film capacitor susceptible to facile machine insertion is fabricated by cyclically advancing a lead frame 32 through a number of stations (36,37) whereat pairs of leads (24,26) of the lead frame are bent downwardly and secured to end electrodes (22,23) formed on the capacitors, and then boxes (29) partially filled with encapsulant are moved over each capacitor secured to a pair of leads. Next, the lead frame is advanced to move each box and capacitor into position to receive additional encapsulant from a nozzle (38) which is projected through a feed hole (34) formed in the lead frame.
