Abstract

1,179,145. Tape reels. BELL & HOWELL CO. 31 Oct., 1967 [10 Nov., 1966 (2)], No. 49463/67. Heading B8M. [Also in Division G2] A take-up reel for cine films, record tape, or other web having perforations, has flanges 15, 16 spaced by a hub on which is mounted a slipping sprocket ring 43 whose teeth 45 engage the perforations or notches 47 in the first convolution of the web coil 35, the ring being pressed into frictional engagement with an annular abutment surface of the hub by spring fingers 53. The fingers 53 extend from an annular base 51 into separate windows 49 of the hub, and may be formed in groups of different thickness and resilience to provide variable braking torque on ring 43. The periphery of ths hub is tapered to reduce friction, with the web, and the flanges may be inclined outwardly. Six spaced key-ways are provided radially of the spindle passage 27.
