<p>A reel spring (10) for a magnetic tape cassette is formed from an elongated strip of stainless steel. The strip defines first and second edges extending throughout its length parallel to a longitudinal centerline. The strip has a flat, central base portion (18) terminating at a first pair of transverse crimp lines (22). The crimp lines define transition sections (24) which extend out of the plane of the base portion at a first angle. A second pair of transverse crimp lines (26) at the ends of the transition sections define end portions of the strip. The end portions extend at a second angle to the plane of the base portion. The width of the strip between the first and second edges is about .315 inches. <IMAGE></p> |
