ABSTRACT:
Two spaced stacks of magnetically soft E-cores, (17 and 18) are supported in spaced relation by pairs of magnets (38 and 39) on opposite sides of each stack. A pair of shuttles (41 and 47) move alternately toward and away from each other and under the stacks to pick off the lower core in each stack. The shuttles alternately advance the cores into a transformer frame (10) where a pair of magnets (66 and 67) are effective to hold the cores in an assembled position within the frame while the shuttles return for another E-core feeding operation. Entry of the cores into the frame is facilitated by a pair of rotating drums (71 and 72) having staggered arrays of magnets (78 and 79) which act to rapidly vibrate the E-cores (17 and 18) and thus prevent lodging of the cores against the frame.
