ABSTRACT:
A continuous strip (16) of metal with boxed discrete capacitors (10) assembled thereon is cyclically advanced to move a leading section of the strip into a positioned chamber (48) of a multi-chamber magazine (46). After a predetermined number of advancements of the strip, a cutter (76,83) is operated to sever the strip and then an auxiliary feed device (107-118) is rendered effective to advance the trailing extremity of the severed strip into the magazine chamber. Immediately thereafter the magazine is indexed to position another chamber to receive a subsequently advanced section of the strip. Upon loading of a magazine with a strip and assembled capacitors in each chamber, facilities (127-142) are rendered effective to advance a new magazine into position to receive additional sections of the strip with the assembled capacitors.
