ABSTRACT:
A storage reel (10, 10') particularly adapted for winding bandoliered, axially leaded, tubular components thereon, such as capacitors (18), includes a core (12, 12') formed with a uniquely configured peripheral relief (32, 44, 46). The relief, in accordance with one preferred embodiment (32), has a concave base, and is dimensioned to accommodate the lower half body portions of a predetermined number of bandoliered, forward end capacitors (18), when wound as part of the first wrap of such components on the core, via a pair of laterally spaced lead-supporting tape carriers (26, 27). The relief is centrally located on the core so as to define on each side thereof a circumferentially displaced, lead-supporting peripheral core border region (12a or b). The relief, as dimensioned and located, cooperates with the core border regions to eliminate any possible tape carrier-induced bending of those bandoliered components in the first wrap that are partially nested therewithin, and to substantially minimize the otherwise maximum possible bending that can occur in the leads of those components in the second wrap that overlie the relief. Thereafter, the then considerably larger, and progressively increasing, effective diameter of the core, and the use of a paper separator (29) interposed between adjacent wraps, both contribute in preventing any detrimental permanent bends being formed in the leads as the capacitors continue to be wound in bandolier fashion on the reel core.
