Abstract

1,167,445. Tape reels. GRUNDIG E.M.V. ELEKTRO MECHANISCHE VERSUCHSANSTALT, INH. MAX GRUNDIG. 23 Jan., 1968 [23 Jan., 1967], No. 3547/68. Heading B8M. [Also in Division G5] A reel, for use in auto-threading tape recording apparatus, see Division G5, comprises a core 6 and concentric annular support 8 mounted for limited relative rotation and defining a space 9 between them to accommodate a leader 11 attached to the core and coupling members 10, 19 on the leader and a cassetted tape respectively. The core is initially driven by a clutch until a peg 32 on the upper reel portion (7, Fig. 3, not shown) engages the end 31 of a groove 29 in the core whereupon both portions rotate together. An outwardly-biased, pivoted sector 28 is freed from a fixed spring catch 33a and closes the gap 27 as winding proceeds. Resilient material 35 at the groove ends reduces shock.
