Plastic tape reel |
摘要 |
Recording tape reel having a plastic hub of I-beam construction and a pair of plastic flanges interconnected by an annular array of radially-elongated lugs through slots in the central web of the hub. Clearances permit the hub to be compressed under forces applied by a wound tape without substantially transmitting those forces to the flanges.
